How to Source Aluminum Alloy from China: Grades, Suppliers, RFQ & Import Guide
To source aluminum alloy from China successfully, do not start with price per ton. Start with the exact product form, alloy, temper, standard, dimensions, tolerance, surface, application and inspection requirement. Only then should you compare suppliers and commercial terms.
A 3003-H24 roofing coil, 6061-T6 machining plate, 6063 extrusion and 8011 foil stock require completely different production routes and supplier capabilities. The best Chinese aluminum supplier is therefore the one that matches your specification—not simply the supplier with the lowest quote.
How to Source Aluminum from China: 7-Step Buyer Checklist
The safest sourcing sequence is: define the application → choose product form → specify alloy + temper → issue a complete RFQ → verify supplier capability → approve quality requirements → check landed cost and compliance before placing the PO.
Tell the supplier whether the material will be formed, machined, welded, anodized, coated, rolled into foil, exposed outdoors or used as a structural component.
Decide whether you need sheet, plate, coil, strip, foil stock, bar, billet or extrusion.
“6061 aluminum” or “3003 coil” is incomplete. Use specifications such as 6061-T6 or 3003-H24.
Include standard, dimensions, tolerances, finish, quantity, inspection, packing, destination and Incoterm.
Confirm whether the company is the mill, processor or trader and whether it regularly supplies your exact product form and alloy.
Use MTC review, dimensions, surface inspection, sample approval, PMI or NDT where applicable.
Review freight, duties, trade remedies, customs classification and any current Chinese export-control requirement before signing.

Mill, Processor or Trading Company: Which Chinese Supplier Do You Need?
| Supplier Type | Best Fit | Main Advantage | What to Verify |
|---|---|---|---|
| Mill | Large repeat orders and standard production programs | Direct production control and stable batch supply | Actual product range, MOQ, lead time and export capability |
| Processor / Service Center | Slitting, cutting, film, coating or cut-to-size requirements | Flexible dimensions and downstream processing | Which processes are in-house and inspection capability |
| Trading / Sourcing Company | Mixed products, smaller quantities and multi-supplier projects | Supplier coordination and consolidated purchasing | Traceability, source transparency and quality-control process |
1. Why Buyers Source Aluminum Alloy from China
China offers a broad supply base for aluminum sheet, plate, coil, strip, foil stock, billet, bar, rod and extruded profiles. Many export programs also combine mill supply with slitting, cutting, protective film, coating, anodizing and export packing.
This can reduce the number of suppliers required for a project, but only when the sourcing company or mill can demonstrate reliable technical control and traceability.
Broad Product Range
Common industrial alloys and product forms can often be consolidated within one sourcing program.
Processing Capability
Slitting, cutting, film, coating and custom packing can reduce downstream handling.
Commercial Scale
Standard grades, repeat orders and common sizes usually provide the strongest cost advantage.
2. Main Aluminum Product Forms Available from China
Aluminum Sheet and Plate
Sheet and plate serve machinery, enclosures, tooling, transportation, signs, building panels and CNC-machined parts. State thickness, width, length, flatness, surface condition and tolerance.
ASTM currently lists ASTM B209/B209M-21a as the active specification for aluminum and aluminum-alloy sheet and plate.
Aluminum Coil and Strip
Coil and strip are widely used for roofing, cladding, heat exchangers, electronics, transformers and stamped parts. Narrow-width coil orders should define edge condition and slitting tolerances before quotation.
See LYH's Slitting Service .
Aluminum Foil Stock
Food foil, pharmaceutical foil, container foil, capacitor material and battery-related foil stock can require different alloy and rolling routes. Tell the supplier the final use and final gauge before accepting an alloy recommendation.
Aluminum Bar, Rod and Billet
Bar, rod and billet are used for machining, forging, extrusion and structural components. Specify diameter, length, temper, straightness, machining allowance and any ultrasonic or mechanical-test requirement.
Aluminum Profiles and Extrusions
Profiles are widely used in solar frames, machine structures, doors, windows, electronics and heat sinks. Confirm drawing tolerances, wall thickness, die requirements, straightness, anodizing or coating and packing protection.
ASTM currently lists ASTM B221-21 as active for aluminum-alloy extruded bars, rods, wire, profiles and tubes.
3. How to Choose the Right Aluminum Alloy Grade
| Series | Typical Grades | Main Strength | Common Applications |
|---|---|---|---|
| 1xxx | 1050, 1060, 1100, 1235 | Purity, conductivity, formability | Electrical, foil, heat transfer, deep drawing |
| 3xxx | 3003, 3004, 3105 | Formability + moderate strength | Roofing, cladding, cookware, heat exchangers |
| 5xxx | 5052, 5083, 5754 | Corrosion resistance + weldability | Transportation, marine, outdoor fabrication |
| 6xxx | 6061, 6063, 6005A, 6082 | Balanced strength, extrusion, machining | Profiles, structures, solar, CNC parts |
| 2xxx / 7xxx | 2024, 2A12, 7075, 7A04 | High strength | High-load and performance-critical components |
| 8xxx | 8006, 8011, 8021, 8079 | Foil-specific processing behavior | Packaging, pharmaceutical and specialty foil |
6061 vs 6063
6061 is widely selected for machined and structural components, while 6063 is widely used for extrusions where profile quality, anodizing and appearance matter.
High-Strength 2xxx and 7xxx Alloys
For 2024, 2A12, 7075 and similar high-strength products, chemistry alone does not confirm final performance. Temper, mechanical tests, heat treatment, traceability and any required NDT should be included in the PO.
4. Aluminum Temper Is Part of the Grade
One of the most common sourcing mistakes is specifying the alloy but not the temper. 3003-O and 3003-H24 are not interchangeable, just as 6061-T6 is not equivalent to an unspecified 6061 product.
| Temper | General Meaning | Buyer Interpretation |
|---|---|---|
| F | As fabricated | Properties may depend heavily on manufacturing route |
| O | Annealed | Soft condition, strong forming capability |
| H | Strain hardened | Common for non-heat-treatable sheet and coil |
| W | Solution heat treated | Generally an unstable transitional condition |
| T | Thermally treated | Common for heat-treatable alloys such as 6061-T6 |
5. How to Write an Aluminum RFQ That Gets a Comparable Quote
Supplier quotations are only comparable when the technical and commercial scope is the same.
- Product form: sheet, plate, coil, strip, foil stock, bar, billet or profile.
- Alloy + temper: e.g. 5052-H32 or 6061-T6.
- Standard: ASTM, EN, GB, customer drawing or another specified basis.
- Dimensions: thickness, width, length, diameter, coil ID/OD or profile drawing.
- Tolerances: thickness, width, flatness, straightness, burr, camber or dimensional profile limits.
- Surface: mill finish, anodized, coated, protective film, oil or cleanliness requirement.
- Quantity: tons, pieces, coils or annual demand.
- Inspection: MTC, mechanical test, dimensions, surface, PMI or NDT as required.
- Packing: pallet/skid, moisture barrier, coil orientation and seaworthy protection.
- Commercial: destination, Incoterm and required delivery date.
Example: Weak RFQ vs Quote-Ready RFQ
Weak
“We need aluminum coil. Please send your best price.”
Better
“Please quote 3003-H24 aluminum coil, 0.8 mm × 1220 mm, mill finish, slit edge, 25 MT, MTC, seaworthy packing, CIF Jebel Ali.”
Useful RFQ Tools
6. How to Verify a Chinese Aluminum Supplier
Technical Fit Comes Before Price
Ask whether the supplier regularly produces or processes your exact form, alloy, temper and dimensional range. A supplier that has never produced thin foil stock should not be evaluated the same way as a specialist foil mill.
First-Order Supplier Checklist
| Check | What to Ask For | Why It Matters |
|---|---|---|
| Company / factory identity | Business information and production location | Confirms who actually manufactures or processes the material |
| Product capability | Recent examples in similar alloy, temper and size | Reduces trial-and-error risk |
| Quality documents | MTC sample and inspection format | Confirms test scope and traceability |
| Surface / tolerance control | Measurement method and defect criteria | Prevents disputes after production |
| Sample / trial | Trial material for sensitive products | Validates forming, coating, machining or appearance |
| Export packing | Packing drawing / photos / packing standard | Prevents moisture, edge and transport damage |
| Pre-shipment inspection | Dimensions, surface, quantity, documents and packing | Finds defects before the container leaves China |
Samples and Trial Orders
Sample approval is especially useful for anodized profiles, coated sheet, deep-drawing material, decorative surfaces and foil stock. Keep the approved sample, drawing and inspection record as the baseline for repeat orders.
Inspection Before Shipment
First orders should normally verify the MTC, dimensions, visual surface, quantity, labeling and export packing before shipment.
See: LYH Quality Inspection .
For appearance-sensitive material, also review: Surface Finishing .
7. Aluminum Pricing, Payment and Incoterms
Aluminum quotations normally combine the metal basis with conversion cost and any premium for alloy, temper, dimensions, coating, film, processing, packing and freight.
Buyers can use the LME Aluminium page as a market benchmark, but the final supplier conversion price still depends on the specific product.
Do Not Compare Different Incoterms
| Incoterm | Buyer Interpretation |
|---|---|
| EXW | Buyer takes the largest logistics responsibility from supplier premises |
| FOB | Supplier delivers the goods for export shipment at the agreed port |
| CFR | Supplier includes ocean freight but not buyer-arranged cargo insurance |
| CIF | Supplier includes ocean freight and specified insurance |
| DAP | Supplier arranges delivery to the agreed destination point, excluding import clearance/duties unless otherwise agreed |
8. Export Packing and Shipping Documents
Sheet / Plate
Use moisture protection, interleaving, edge protection and stable pallets or skids.
Coil / Foil
Confirm eye orientation, edge guards, moisture barrier, skid design and container securing.
Profiles / Bars
Protect visible surfaces, ends, bundle supports and lifting points.
Typical Shipping Document Set
- Commercial invoice
- Packing list
- Bill of lading
- Mill Test Certificate where required
- Certificate of origin where required
- Inspection report where specified
- ISPM-15 evidence for regulated wooden packaging where applicable
For early material-weight planning, see the Metal Density Chart .
9. HS Codes, Trade Remedies and China Export-Control Screening
Common HS Headings
- 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.
These are broad HS headings. Final customs classification depends on the actual product, alloy, dimensions, processing and destination-country tariff.
Anti-Dumping and Countervailing Duties
Some markets apply trade remedies to selected Chinese aluminum sheet, foil, extrusions or related products. Always verify current product scope with a customs broker before calculating landed cost.
Useful official starting points include the WTO Trade Remedies Data Portal and the EU Access2Markets portal.
China Dual-Use Export-Control Screening
Most ordinary commercial aluminum orders should not be treated as controlled simply because the alloy is high strength. However, selected aluminum products can fall within China's dual-use export-control framework depending on technical parameters, physical form, end user and end use.
Because the controlled-items list can be updated, buyers should not rely on a permanently embedded threshold copied from an older article. The Chinese exporter should classify the actual item against the current list at the time of order and obtain the required authorization where applicable.
For potentially sensitive high-strength bars, tubes or special industrial material, be prepared to provide end-user and end-use information.

Regulations: Regulations on Export Control of Dual-Use Items .
10. Common Mistakes When Buying Aluminum from China
Buying by Alloy Only
Alloy without temper, tolerance, product form and application is not a complete specification.
Comparing Unequal Quotes
EXW and CIF, mill finish and coated, or standard and tight-tolerance products cannot be compared directly.
Skipping Samples
Surface-critical, coated, anodized, foil and deep-drawing material often needs trial approval.
Ignoring Packing
Moisture, coil movement, edge damage and profile abrasion can destroy otherwise acceptable material.
Checking Duties Too Late
Trade-remedy exposure can completely change landed cost.
No Pre-Shipment Inspection
First discovering a size, surface or packing problem after the container arrives is far more expensive.
Aluminum Sourcing Tools and Quality Support
FAQ: Sourcing Aluminum Alloy from China
1. What should I send a Chinese aluminum supplier for a quote?
Send product form, alloy, temper, standard, dimensions, tolerances, quantity, surface, application, inspection requirements, packing, destination and Incoterm.
2. How do I choose an aluminum supplier in China?
Start by confirming whether the supplier regularly handles your exact alloy, temper, form and dimensional range. Then review MTC capability, tolerance control, samples, inspection support, export experience and packing.
3. Should I buy directly from an aluminum mill?
Not always. Mills fit large repeat programs, while processors are often better for slitting, coating and custom dimensions. A sourcing company can be useful for mixed products or multi-supplier orders.
4. Why is aluminum temper important?
Temper affects strength, hardness, elongation and forming behavior. Always specify the alloy and temper together.
5. Which aluminum grades are common for sheet and coil?
Common examples include 3003, 3004, 3105 and 5052 for general sheet and coil, although the correct grade depends on forming, coating and service environment.
6. Which aluminum grades are common for CNC machining?
6061 and 6082 are common general-purpose machining alloys. 2024 and 7075 are used where higher strength is needed, subject to the required temper and certification.
7. Can Chinese aluminum suppliers provide an MTC?
Many export suppliers can provide an MTC, but buyers should confirm the actual test scope, batch traceability, standard and document format before production.
8. Do I need a sample before importing aluminum?
Samples are especially useful for coated sheet, anodized extrusions, deep-drawing stock, decorative surfaces and foil products.
9. Do Chinese aluminum products face anti-dumping duties?
Some products do in some markets. Product scope and duty rates change, so check the current destination-country trade-remedy rules before calculating landed cost.
10. Do aluminum exports from China require an export license?
Most ordinary commercial orders should not be assumed to require a license solely because they are aluminum. Selected products may fall within China's dual-use export-control framework depending on their parameters, form, end user and end use. The exporter should screen the current list for each order.
11. What is the normal MOQ for aluminum from China?
MOQ varies by mill, product form, alloy, temper, width, finish and production route. Standard products normally allow lower minimums than custom profiles, special widths or coated products.
12. What is the safest process for a first aluminum order from China?
Issue a detailed RFQ, compare technically equivalent quotations, approve samples where required, lock the specification into the contract and complete pre-shipment inspection before release.
Source Aluminum by Specification, Not by Price Alone
A reliable aluminum order begins with application + product form + alloy + temper + standard + tolerance + surface + inspection.
Once those requirements are fixed, quotations can be compared fairly on price, lead time, processing, packing and logistics.
