How to Source Aluminum Alloy from China: Grades, Specs, Suppliers & Import Tips
When you source aluminum alloy from China, price per ton is only the starting point. A reliable order also depends on alloy, temper, product form, tolerance, surface quality, inspection documents, packing and trade terms.
For example, 3003-H24 roofing coil, 6061-T6 machining bar and 8011 foil stock require different production routes. Therefore, buyers need a clear sourcing method before they compare quotations.
For that reason, this guide gives importers, OEM teams and fabricators a practical buying framework. First, it explains the main product forms and alloy families. Next, it covers tempers, applications, RFQ details and supplier checks. Finally, it reviews pricing, shipping, import duties and selected export-control risks.
Why Global Buyers Source Aluminum Alloy from China
A Broad Supply Base for Aluminum Products
China offers a deep supply chain for aluminum sheet, plate, coil, strip, foil stock, billet, bar, rod and extruded profiles. In addition, many suppliers can arrange slitting, sawing, protective film, surface treatment, inspection and export packing within one order.
Because of that, overseas buyers can source both standard mill products and processed components. For instance, one project may require coated coil, machining bar and anodized profiles from the same supply program.
Competitive Production for Standard Grades
Standard industrial grades and repeat container orders usually deliver the strongest commercial value. Likewise, common sizes generally offer shorter lead times and lower minimum quantities.
However, the lowest price is not always the lowest landed cost. Tight tolerances, non-standard widths, special finishes and small coils can raise conversion fees. Therefore, buyers should compare quotations only after every technical and commercial term matches.
Integrated Processing Can Reduce Purchasing Work
A capable supplier can coordinate mill production and downstream processing. As a result, the buyer works with fewer vendors and receives one set of shipping documents.
This approach is especially useful when the order includes slitting, cutting, protective film, anodizing or cut-to-length service. Nevertheless, buyers should confirm which operations are completed in-house and which are subcontracted.
Why Melt and Casting Routes Matter
Some integrated producers transfer molten primary aluminum directly into casting instead of remelting standard ingot. Consequently, the melt may face less oxidation and re-contamination before filtration.
Even so, a broad marketing claim is not enough. Buyers of foil stock, surface-critical sheet or electrical material should request measurable process information and batch records.
When China May Not Be the Best Route
Very small trial lots and urgent local deliveries may cost more after freight and handling. Similarly, some aluminum products face anti-dumping or countervailing duties in the destination market.
Aerospace-controlled parts, domestic-origin programs and projects with strict local-content rules may also require a different sourcing route. Therefore, regulatory screening should happen before price comparison.
In short, treat China as a complete aluminum supply chain, not only as a low-cost market. The clearer the specification, the easier it is to select the right supplier.
Main Aluminum Alloy Product Forms Available from China
Aluminum Sheet and Plate
Aluminum sheet and plate serve building panels, machinery covers, electrical enclosures, tooling, signs and CNC-machined parts. Therefore, buyers should state thickness, width, length, flatness, surface condition and protective-film requirements.
For flat-rolled products, ASTM B209 is a common official reference. However, the purchase order should still define alloy, temper, dimensions, tolerance and inspection scope.
Surface Acceptance for Sheet and Plate
Decorative and coated sheet needs a clear surface standard. Accordingly, the RFQ should address scratches, roller marks, oil stains, dents, color variation and film type before production begins.
For machined plate, flatness and internal stress may matter more than appearance. Therefore, buyers should explain the cutting and machining route when they request a quote.
Aluminum Coil and Strip
Coil and strip feed roofing panels, wall cladding, transformers, electronics, honeycomb skins and stamped components. In practice, a complete inquiry includes coil ID, maximum OD, maximum coil weight, edge condition and thickness tolerance.
Slit Coil Requirements
When narrow widths are required, confirm the slitting route before approving the quotation. In addition, state burr limits, camber, telescoping limits, slit-width tolerance and packing orientation.
Buyers can review LYH's slitting service for the main processing and inspection points used in coil conversion.
Aluminum Foil Stock
Foil stock supports food packaging, pharmaceutical packaging, containers, capacitors, insulation and battery applications. However, final acceptance often depends on melt cleanliness, hydrogen control, edge quality and downstream rolling behavior.
Why the Final Foil Application Matters
Food foil, pharmaceutical foil, battery foil and container foil require different alloy and processing routes. Therefore, the supplier must know the final gauge, rolling process, annealing condition and cleanliness target.
In addition, the RFQ should define pinhole expectations, edge condition and surface defects. Otherwise, two suppliers may quote technically different foil stock under the same alloy name.
Aluminum Bar, Rod and Billet
Bar, rod and billet serve extrusion, forging, CNC machining, molds and structural components. For these products, buyers should specify diameter, length, straightness, heat-treatment condition and machining allowance.
Internal Quality for Bar and Billet
High-load parts may need ultrasonic testing, mechanical test results or tighter chemistry control. Consequently, the required NDT method and acceptance level should appear on the inquiry.
Large-diameter high-strength round bar may also require additional export-control screening. Therefore, buyers should provide the final end user and end use before signing a contract.
Aluminum Profiles and Extrusions
Aluminum profiles are common in solar frames, heat sinks, machine frames, doors, windows and electronic housings. First, approve the technical drawing. Next, confirm die cost, wall thickness, straightness and dimensional tolerance.
Extrusion Surface and Packing Requirements
Buyers should also define anodizing thickness, powder-coating color, film protection, bundle size and separator material. ASTM B221 covers common extruded bars, rods, profiles and tubes.
The official ASTM B221 page provides the standard scope. Nevertheless, the drawing remains the controlling document for custom profiles.
How to Choose the Right Aluminum Alloy Grade
Alloy selection balances strength, formability, conductivity, weldability, machining performance and corrosion resistance. Usually, improving one target changes another. Therefore, start with the application and downstream production route.
1xxx Series: Purity, Conductivity and Formability
Grades such as 1050, 1060, 1070, 1100 and 1235 offer high aluminum purity and excellent forming behavior. As a result, they suit foil stock, electrical parts, heat-transfer components, reflectors and deep-drawn products.
Their main limitation is lower structural strength. Therefore, they are rarely the first choice for heavily loaded components.
When to Select a 1xxx Alloy
Choose this family when conductivity, reflectivity, corrosion resistance or deep forming matters more than mechanical strength. For example, 1060 and 1100 often appear in electrical, cookware and heat-transfer applications.
3xxx Series: The Sheet and Coil Workhorse
Grades 3003, 3004, 3005 and 3105 combine moderate strength with good forming and corrosion resistance. Consequently, they dominate roofing, wall panels, cookware, tanks and heat-exchanger stock.
3003 vs 3105
Grade 3003 suits general forming and fabrication. Meanwhile, 3105 often appears in coated building products where panel strength and coating performance both matter.
Even so, temper and coating compatibility still affect the final result. Therefore, the base alloy cannot be selected separately from the finishing process.
5xxx Series: Corrosion Resistance and Weldability
Magnesium-alloyed grades such as 5052, 5083 and 5754 provide more strength than 3xxx alloys. In addition, they perform well in humid, outdoor, transportation and marine environments.
When to Select a 5xxx Alloy
Choose this family when corrosion resistance, fatigue strength and welding matter. However, confirm the correct marine, pressure-vessel or transportation standard when the application is safety-critical.
For formed sheet, 5052 provides a useful balance between strength and bendability. By contrast, 5083 targets heavier marine and structural duty.
6xxx Series: Profiles, Machining and Structures
Grades 6061, 6063, 6005A and 6082 balance strength, extrusion performance, machining and corrosion resistance. Therefore, 6061 and 6082 are common for machined or structural parts.
Meanwhile, 6063 and 6005A often suit profiles, architectural systems and solar frames.
6061 vs 6063
Grade 6061 provides higher structural strength and better machining performance. By contrast, 6063 offers better extrusion behavior and surface appearance for architectural or decorative profiles.
Accordingly, 6061 is often the safer choice for machined brackets and structural parts. However, 6063 usually performs better for thin, visible and anodized extrusions.
2xxx and 7xxx Series: High-Strength Applications
Grades 2024, 2A12, 7075 and 7A04 offer high strength. By contrast, they provide less general corrosion resistance and require tighter heat-treatment control.
Use these alloys only when load, stiffness or fatigue performance justifies the added cost. Moreover, require mechanical test results, heat traceability and NDT where the drawing specifies them.
Why Heat Treatment Matters
Strength in 2xxx and 7xxx alloys depends heavily on heat treatment. As a result, a correct chemistry certificate does not prove that the material meets the required mechanical properties.
Therefore, the RFQ should state the exact temper, tensile requirement and inspection document.
8xxx Series: Foil and Packaging Specialties
Grades 8006, 8011, 8021 and 8079 support packaging and foil production. Specifically, buyers select them for rolling behavior, barrier performance, deep drawing and surface cleanliness.
However, one 8xxx grade cannot cover every foil application. Final gauge, annealing route, forming method and hygiene requirements must appear in the RFQ.
Related Material Selection Guides
For a wider conductor-material comparison, see LYH's guide to copper, brass and aluminum in electrical engineering.
Food-equipment buyers can also review 304 stainless steel vs aluminum alloy before choosing a material for direct food contact or equipment frames.
Aluminum Temper Designations: The Half of the Specification Buyers Forget
Why Temper Changes Material Performance
Grade alone is not a complete specification. For example, 3003-O, 3003-H14 and 3003-H24 differ in hardness, elongation and forming behavior.
Therefore, the wrong temper can cause cracking, weak panels, excessive springback or failed deep drawing.
Base Temper Codes
| Temper | Meaning | Buyer Interpretation |
|---|---|---|
| F | As fabricated | Mechanical properties may not be tightly controlled |
| O | Annealed | Softest condition; suitable for forming and deep drawing |
| H | Strain hardened | Used for non-heat-treatable aluminum alloys |
| W | Solution heat treated | Unstable transitional condition |
| T | Thermally treated | Used for heat-treatable grades such as 6061-T6 |
Common H Tempers
H14 means half-hard, while H18 describes a harder condition with lower formability. Meanwhile, H24 combines strain hardening with partial annealing.
H26 provides more strength than H24 for selected stiffness requirements. However, higher hardness usually reduces forming margin.
How the H Subdivision Works
The second digit shows the hardness level. In general, HX1 sits near the soft end, HX4 marks a middle condition and HX8 indicates a hard temper. HX9 means extra-hard.
The first H digit also matters. H1 means strain hardened only. By contrast, H2 means strain hardened and partially annealed.
T Tempers for Heat-Treatable Alloys
Grades in the 2xxx, 6xxx and 7xxx families often use T tempers. For instance, T6 normally indicates solution heat treatment followed by artificial aging.
Even so, buyers should not assume every T6 product has the same properties. The alloy, product form, thickness and governing standard still control acceptance.
A Practical RFQ Rule
Write the alloy and temper together. For example, “3003-H24 aluminum coil, 0.8 mm × 1220 mm” gives suppliers a usable starting point. “3003 aluminum coil” does not.
Aluminum Alloy Selection by Application
The table below gives buyers a practical shortlist. However, the final decision must also account for forming, welding, coating, service environment and customer-specific standards.
| Application | Recommended Grades | Common Forms | Key Buying Points |
|---|---|---|---|
| Food packaging foil | 1235, 8011, 8079, 8006 | Foil stock, coil | Cleanliness, pinholes, surface quality |
| Pharmaceutical foil | 8011, 8021, 8079 | Foil stock | Barrier performance, hygiene, edge quality |
| Heat exchanger and AC fin | 1060, 1100, 3102, 3003 | Coil, strip, foil stock | Conductivity, gauge tolerance, surface |
| Roofing and wall panels | 3003, 3105, 3004, 5052 | Sheet, coil | Flatness, coating, corrosion resistance |
| Cookware and deep drawing | 1060, 1100, 3003 | Sheet, coil | Elongation, temper, surface, forming test |
| Solar frames | 6005A, 6063, 6061 | Profiles, billet | Drawing, extrusion tolerance, anodizing |
| CNC machining | 6061, 6082, 7075 | Plate, bar, billet | Strength, machining, heat treatment, traceability |
| High-load parts | 2024, 2A12, 7075, 7A04 | Bar, plate, profile | Certification, NDT, compliance screening |
Selection Notes for Packaging Products
For packaging foil, cleanliness and rolling behavior can outweigh nominal strength. Therefore, the final application and final gauge must be disclosed before the supplier recommends a grade.
Selection Notes for Building Products
For roofing and wall panels, coating compatibility, flatness, temper and corrosion resistance often drive rejection risk. Consequently, the RFQ should define both the base metal and coating system.
Selection Notes for Solar Profiles
Solar profiles need an approved drawing, stable extrusion dimensions and controlled anodizing. In addition, packing must prevent profiles from rubbing against each other during sea freight.
Selection Notes for CNC Parts
For machined components, determine whether the part will be welded, anodized or highly loaded. As a result, the choice between 6061, 6082 and 7075 becomes easier.
How to Write an Aluminum RFQ That Gets an Accurate Quote
Information Every RFQ Should Include
- Product form: sheet, plate, coil, strip, foil stock, bar, billet or profile.
- Alloy grade, temper and governing standard.
- Dimensions and tolerance requirements.
- Quantity in metric tons, pieces, coils or containers.
- Surface condition, protective film and edge condition.
- Application and downstream processing route.
- MTC, chemical testing, mechanical testing and inspection needs.
- Export packing, destination port and Incoterm.
Extra Information for Aluminum Coil
State coil ID, maximum OD, maximum coil weight, edge type, rolling direction and packing orientation. In addition, define surface protection, slit-width tolerance and burr limits.
Extra Information for Foil Stock
State the final foil use and final gauge. Moreover, specify pinhole limits, surface cleanliness, edge quality, annealing route and any hydrogen-control requirement.
Extra Information for Bar and Billet
State straightness, heat treatment, machining allowance, mechanical requirements and NDT. For high-strength round bar, provide the final end user and end use for compliance screening.
Extra Information for Aluminum Profiles
Attach a drawing with alloy, temper, length, wall thickness and tolerance. Then define die ownership, sample approval, finish, color, film and packing.
Weak RFQ vs Professional RFQ
Weak: “We need aluminum coil. Please send price.” Better: “Please quote 3003-H24 coil, 0.8 mm × 1220 mm, mill finish, slit edge, 25 MT, CIF Jebel Ali, with MTC and seaworthy packing.”
Useful RFQ Preparation Tools
Before release, use LYH's Dimensional Tolerance Calculator as a discussion aid.
For early freight planning, the Metal Weight Calculator can support a shipment-weight estimate.
What Separates a Reliable Aluminum Supplier from a Cheap One
Understanding of Grade and Temper
A reliable supplier asks about forming, welding, anodizing, machining and service conditions before quoting. Therefore, an instant price with no technical questions should trigger further review.
Melt Cleanliness and Hydrogen Control
For demanding foil or surface-critical products, ask for measurable production controls. For example, a mill may monitor hydrogen through online analysis.
However, the buyer should request records for the actual production route rather than rely on a general statement.
Degassing and Filtration
Effective filtration removes coarse and fine inclusions before casting. In practice, filter-media condition, metal flow, degassing stability and change intervals influence final cleanliness.
Surface and Flatness Control
For lighting, electronics, architecture and decorative sheet, surface and flatness drive production yield. Therefore, agree the measurement method and defect limits before the trial order.
Metallurgical Control for Foil Stock
Battery and packaging foil stock needs more than rolling capacity. Specifically, particle distribution, annealing control, melt cleanliness and grain uniformity affect downstream performance.
Batch-to-Batch Consistency
One approved sample does not prove stable serial production. Instead, compare chemistry, mechanical properties, thickness, surface and forming behavior across later batches.
Documentation and Packing Ability
A qualified export supplier should provide an MTC, dimensional report, packing list, invoice and product labels. In addition, the supplier should support certificates of origin and third-party inspection where required.
For first orders, define checks through LYH's Quality Inspection page.
Surface-sensitive buyers can also review the Surface Treatment workflow.
How to Evaluate and Select a Chinese Aluminum Supplier
Identify the Supplier Type
A mill fits large standard orders and stable repeat programs. By contrast, a processor fits slitting, coating, cut-to-size work or custom finishing.
A trading company may suit mixed sourcing and smaller lots. Therefore, the best supplier type depends on quantity, product mix and processing needs.
Check Product and Process Fit
Ask whether the supplier regularly handles your product form, grade, temper and size range. Moreover, request recent production examples that match the required thickness, diameter or finish.
Review Technical Communication
Confirm standards, tolerances, MTC format, packing, export experience and inspection support. In addition, ask about duty or export-license risks before the contract is signed.
Use Samples for Appearance-Sensitive Products
Samples are valuable for coated sheet, anodized profiles, deep-drawing stock and foil. Likewise, third-party inspection can reduce first-order risk.
Audit Critical Suppliers
For long-term or high-value programs, consider a factory audit. The audit should cover production equipment, calibration, traceability, nonconforming-material control, packing and complaint handling.
Pricing, Payment and Trade Terms for Aluminum Imports
How Export Aluminum Prices Are Built
Most quotations combine a metal basis, regional premium and conversion fee. Suppliers then add alloy, temper, dimensions, surface treatment, packing, freight and currency effects.
Because aluminum prices move, quotations often have short validity. Buyers can review the official LME Aluminium page for benchmark-market information.
Avoid False Price Comparisons
Do not compare an EXW offer with a CIF offer. Likewise, do not compare mill-finish coil with coated or slit material.
Tight tolerances, smaller coil weights and protective film can also change conversion cost. Therefore, normalize every commercial and technical term first.
Common Incoterms
| Incoterm | Buyer Meaning |
|---|---|
| EXW | Buyer controls pickup and export; highest buyer responsibility |
| FOB | Supplier delivers to port and clears export |
| CFR | Supplier includes ocean freight; buyer arranges insurance |
| CIF | Supplier includes ocean freight and insurance |
| DAP | Supplier delivers near destination; quoted price is higher |
Payment Terms for First Orders
T/T and irrevocable L/C at sight remain common. However, first orders should balance deposit risk with inspection, production progress and shipping documents.
What the Contract Should Lock
Record alloy, temper, standard, tolerance, surface, inspection, packing, delivery date and Incoterm in the sales contract. Otherwise, later discussions may rely on assumptions rather than agreed requirements.
Logistics, Export Packing and Shipping Documents
Sheet and Plate Packing
Use moisture barriers, interleaving material, edge protection and stable pallets. In addition, labels should show alloy, temper, size, lot reference and quantity.
Coil and Foil Packing
Confirm eye-to-wall or eye-to-sky orientation. Then require inner and outer protection, edge guards, moisture barriers, stable skids and secure container bracing.
Profile and Bar Packing
Profiles need film, separators and end protection. Meanwhile, bar bundles need stable supports, surface protection, clear length marking and sufficient lifting points.
Standard Shipping Documents
The usual document set includes the commercial invoice, packing list, bill of lading, MTC and certificate of origin when required. Wooden packaging may also require ISPM-15 evidence.
Plan Container Weight Early
To estimate shipment weight, use LYH's Metal Density Chart.
Aluminum is light compared with steel. Nevertheless, dense coil orders may still reach container weight limits before they use all available volume.
HS Codes, Import Duties and Anti-Dumping Risks
Common HS Categories for Aluminum
- 7601 — unwrought aluminum.
- 7604 — aluminum bars, rods and profiles.
- 7606 — aluminum plates, sheets and strip over 0.2 mm.
- 7607 — aluminum foil up to 0.2 mm.
- 7608 — aluminum tubes and pipes.
- 7610 — aluminum structures and structural parts.
Why Correct Classification Matters
The final customs code drives duty, documentation and trade-remedy exposure. However, the correct subheading depends on alloy, form, thickness, processing and destination-country rules.
Anti-Dumping and Countervailing Measures
Some markets apply anti-dumping or countervailing duties to Chinese foil, common-alloy sheet or extrusions. Therefore, check the current measure with a customs broker before calculating landed cost.
The WTO Trade Remedies Data Portal and the European Union's Access2Markets portal are useful official starting points.
Country-Specific Duty Changes
Duty rates and product scopes change over time. For one market example, review LYH's article on Thailand aluminum extrusion duties.
Even so, use current customs advice for the final landed-cost decision.
China Export-Control Screening for High-Strength Aluminum
Why Some Orders Need Extra Review
Most commercial aluminum sheet, coil, foil and standard profiles are not affected by the specific high-strength cylindrical-product test discussed below.
However, selected high-strength round bars and tubes require careful screening before the exporter confirms shipment.
The 1C202 Aluminum Test
Entry 1C202 covers aluminum alloys that meet two conditions. First, the alloy must be capable of reaching at least 460 MPa ultimate tensile strength at 20°C.
Second, it must be supplied as a tube or solid cylindrical bar, including forgings, with an outside diameter above 75 mm.
Why “Capable of” Matters
The phrase “capable of” includes strength that can be achieved after heat treatment. Therefore, shipping an alloy in O or F temper does not automatically create an exemption.
Which Orders Need Early Screening
Large-diameter 2024, 2A12, 7075 or 7A04 round bar may require additional review. By contrast, flat-rolled sheet, coil and foil generally sit outside the cylindrical-form test.
Information the Buyer Should Provide
The Chinese exporter completes the formal screening and any required application. Meanwhile, the overseas buyer may need to provide end-user information, end-use information and non-diversion commitments.
A supplier that asks these questions is showing compliance discipline rather than creating unnecessary paperwork.
Official Compliance Sources
Review MOFCOM Announcement No. 51 of 2024 and the Dual-Use Items Export Control Regulations.
Import duties and Chinese export licensing are separate compliance gates. Clearing one does not clear the other. This article provides general guidance and is not legal advice.
Common Mistakes Aluminum Buyers Should Avoid
Buying by Alloy Name Alone
An alloy without temper, tolerance, surface, form or application is incomplete. Consequently, suppliers may quote different products under the same general grade name.
Ignoring the Temper
A wrong temper can cause forming cracks, weak panels, excessive springback or poor machining. Therefore, temper should appear beside the alloy on every purchase document.
Comparing Different Commercial Terms
EXW, FOB, CFR and CIF prices are not directly comparable. Likewise, a basic mill-finish quotation should not be compared with a coated, slit, filmed and inspected product.
Skipping Samples for Sensitive Products
Coated sheet, anodized profiles, deep-drawing stock and foil products often need samples. Otherwise, the first full container may become the first real production trial.
Ignoring Export Packing
Moisture, edge damage, coil movement and profile abrasion can create major losses. As a result, packing should be agreed before production, not after the goods are finished.
Checking Duties Too Late
Anti-dumping duties can change the landed-cost calculation completely. Therefore, confirm the customs treatment before approving the purchase order.
Discovering Compliance Issues After Signing
High-strength large-diameter round bar may require additional documentation or licensing review. Early screening protects both the buyer's schedule and the exporter's compliance position.

Frequently Asked Questions About Sourcing Aluminum Alloy from China
Grade and Specification Questions
What is the best aluminum alloy to import from China?
No single grade is best. For example, 1050 and 1060 suit conductivity and forming, while 3003 and 3105 suit general sheet and coil. Meanwhile, 5052 adds corrosion resistance, and 6061 or 6082 suits machining and structural parts.
What should I include in an aluminum RFQ?
Include product form, alloy, temper, standard, dimensions, tolerances, quantity, surface, application, packing, inspection documents, destination port and Incoterm. In addition, provide end-use details for high-strength large-diameter bar.
What is the difference between 3003 and 5052 aluminum?
Grade 3003 offers good forming and moderate strength for cookware, roofing and general sheet. By contrast, 5052 offers higher strength and better corrosion resistance for outdoor, marine and structural-sheet applications.
Is 6061 or 6082 better for machining?
Both alloys machine well. Usually, 6061 offers broad availability and balanced performance. However, 6082 can provide higher strength in selected tempers. Final selection depends on the drawing, load, tolerance and supply range.
Which aluminum grades are common for foil stock?
Common grades include 1235, 8011, 8079, 8006, 8021, 1100, 1060 and 3003. Nevertheless, buyers must also define final gauge, pinhole expectations, cleanliness, annealing and downstream rolling requirements.
Why is aluminum temper important?
Temper governs strength, hardness, elongation and forming behavior. Therefore, the same alloy can perform very differently in O, H14, H18, H24 or T6 condition.
Supplier, Shipping and Compliance Questions
Can Chinese suppliers provide a mill test certificate?
Many export-oriented suppliers can provide an MTC. However, buyers should confirm the standard, test items, batch traceability and document format before production starts.
Do aluminum alloys from China require an export license?
Most standard flat-rolled products do not fall under the high-strength cylindrical-product test. However, selected high-strength tubes or solid round bars over 75 mm may require further review. Verify the current rules for each order.
How can I reduce aluminum quality problems?
Use a complete specification, approved samples, an MTC, clear surface limits and pre-shipment inspection. In addition, confirm moisture protection and container loading before shipment.
Do I need to check anti-dumping duty?
Yes. Some Chinese aluminum sheet, foil and extrusions face trade remedies in certain markets. Therefore, verify the current measure and product scope with a local customs broker before ordering.
What is the usual MOQ for aluminum products?
MOQ depends on product form, grade, temper, width and production route. Generally, standard sizes have lower minimums. Custom widths, special profiles and surface-treated products require larger production runs.
Source Aluminum by Specification, Not by Price Alone
Overall, a reliable aluminum order starts with alloy, temper, product form, tolerance, surface and final application. Once those points are clear, buyers can compare price, packing, documents and delivery on an equal basis.
In addition, clear both regulatory gates before signing. The destination market may apply import duties or trade remedies, while China may require extra screening for selected high-strength cylindrical products.
Send your grade, temper, dimensions, application, annual volume and destination port through Contact Us. If the alloy is not yet fixed, LYH can review the application and help prepare a quote-ready specification.
Note: Alloy properties, import duties and export-control entries can change by standard, destination and date. Confirm current requirements before ordering.
