Import Pure Copper from China: C11000, C10200, C12200 Buyer's Guide

Why "Pure Copper" Is Not Enough for International Procurement

Many buyers send inquiries for "pure copper," "red copper," or "copper sheet from China." However, the supplier may quote T2, TU1, TU2, TP1 or TP2, while the drawing actually specifies C11000, C10200, C10100 or C12200. These grades are commercially related, yet they are not always interchangeable.

One Word Hides Several Different Materials

In practice, "pure copper" means different things by application. For example, C11000 suits busbars and general electrical parts, while C10200 and C10100 target vacuum and high-purity duty. By contrast, C12200 is built for tube, HVAC and brazed systems. As a result, a single label cannot guide a serious purchase.

Pricing adds another layer. LME-linked copper value moves daily, yet not every quotation separates raw metal cost from processing fee. Moreover, a supplier may send an MTC, but buyers still need to verify grade, standard, heat number, chemistry, temper and conductivity before they trust it.

Not sure whether you need C11000, C10200 or C12200? Therefore, send your application and drawing first, and the team can help identify the right grade before you request pricing through the pure copper product range.

Why International Buyers Source Pure Copper from China

A Mature Ecosystem for Copper Semis and Custom Parts

China has a deep supply base for copper semis, tube mills, strip processing, busbar fabrication and cut-to-size parts. In addition, many foreign buyers do not need raw mill output. Instead, they need a partner who can slit, punch, bend, machine, pack and document the product correctly.

Because of that, China is especially competitive for C11000 sheet, plate, strip and busbar; for C12200 tube and pipe; and for slit strip, coil and drawing-based components. By contrast, it is less convenient for very small lots of specialty high-purity copper, or for jobs where the buyer cannot define standard, tolerance or documentation.

Plan Around the Production Calendar

One practical risk is timing. Chinese New Year (usually late January to mid-February) and Golden Week (the first week of October) pause most mills and fabricators for one to three weeks. Therefore, buyers shipping in February or October should confirm capacity and shipping cut-off at least six weeks ahead, and agree the LME fixing date in writing to avoid price drift during the closure.

In short, China is often competitive when buyers define the grade, product form, tolerance, inspection requirement and export packing clearly, not simply when they ask for the lowest price.

Pure Copper Grades at a Glance

First, here is the comparison many buyers keep on hand. Still, treat it as a shortlist tool, because the final pick depends on the drawing, the standard and the service.

Grade-by-Grade Selection Guide: Six Pure Coppers Buyers Should Know

Next, here is each grade in practical buyer language. For each one, the logic combines purity, conductivity and joining behavior.

C11000 ETP Copper — The Default for General Electrical Use

C11000 is the standard commercial pure copper for many electrical, thermal and industrial parts. Namely, it offers high conductivity, good ductility and broad availability across sheet, plate, strip, busbar, rod and wire. In Chinese terms, buyers usually see T2 or T1 type, and the relevant references include ASTM B152 and ASTM B187. For sheet, strip and bar requirements, the international standard ASTM B152 is the right one to cite.

However, do not default to C11000 for vacuum, reducing-atmosphere or hydrogen-sensitive duty. In those cases, C10200 or C10100 is safer.

C10200 Oxygen-Free Copper — When Oxygen Content Matters

C10200 is oxygen-free copper, selected when buyers need cleaner chemistry and stable behavior in special environments. As a result, it suits vacuum components, RF and microwave parts, battery connectors and high-performance busbars. The Chinese reference is usually TU1 or TU2 type.

Still, do not over-specify C10200 when ordinary C11000 already meets the electrical and processing requirement. Because oxygen-free copper costs more, the application should justify it.

C10100 OFE Copper — For High-Purity Electronic and Scientific Parts

C10100 is oxygen-free electronic copper, chosen for extremely low impurity levels and high reliability. For example, it appears in vacuum electronic devices, semiconductor-related parts, accelerator components and precision scientific equipment. In China, TU0 type is the common reference.

By contrast, C10100 is not a low-cost industrial grade. Therefore, specify it only when the drawing or service condition truly requires OFE-level purity.

C12200 DHP Copper — The Preferred Grade for Tube and HVAC

C12200 is phosphorus-deoxidized copper, and it is one of the most important tube grades because it brazes and solders well. Consequently, it dominates HVAC systems, refrigeration lines, heat exchangers, plumbing and brazed tube assemblies. The Chinese reference is TP2 type. For air-conditioning and refrigeration tube in North America, cite ASTM B280; for European refrigeration duty, cite EN 12735.

Even so, C12200 is not the first choice for high-conductivity busbars. So buyers should not pick it only because "brazing is easier" when the duty needs maximum conductivity.

C12000 DLP Copper — Balanced Joining and Conductivity

C12000 is low-phosphorus deoxidized copper. Accordingly, it fits buyers who need good formability, brazing or welding while keeping useful conductivity. Typical parts include heat exchanger components, brazed assemblies and formed tube. The Chinese reference is TP1 type.

However, when maximum conductivity is the main requirement, compare C12000 carefully against C11000 or C10200 before ordering.

C10700 / C11600 Silver-Bearing Copper — For High-Temperature Electrical Parts

C10700 and C11600 contain silver to resist softening at elevated temperature. As a result, they suit electrical contacts, commutator segments, resistance welding parts and motor components. The Chinese reference is TAg type.

Still, silver-bearing copper is a specialty material. Therefore, it should not replace ordinary copper sheet, plate or tube unless the temperature and electrical duty justify it.

Chinese Copper Grade Equivalents: Useful, But Not Always Identical

Because many buyers search for Chinese equivalents, a clear translation table helps. However, an equivalent name is a communication aid, not a substitute for the governing standard.

How to Decode the Chinese Designation

The prefix carries the meaning. For instance, T marks tough-pitch copper (T2 is standard commercial purity), while TU marks oxygen-free copper (TU0 is the highest purity, TU1 and TU2 allow more oxygen). Meanwhile, TP marks phosphorus-deoxidized copper (TP1 is low phosphorus, TP2 is standard DHP), and TAg marks silver-bearing copper.

In other words, equivalence is a procurement reference, not a legal substitute for the standard written on the drawing or purchase order. To cross-check fast, buyers can use the Grade Equivalent Chart before the RFQ.

Match the Copper Grade to the Product Form

Buyers do not purchase "copper." Instead, they buy a product form with a grade, a temper and a tolerance. So the form usually decides which details matter most.

Copper Sheet and Plate

For general electrical and industrial sheet, C11000 is the workhorse, while C10200 covers oxygen-free duty and C12000 helps where joining matters. In addition, buyers should state thickness, width, length, tolerance, temper, surface and any cut-to-size need. For flat products, the Copper Sheet and Plate page is the natural entry point.

Copper Strip and Coil

Strip and coil drive connectors, terminals and stamped parts. Therefore, C11000 fits most stamping, while C10200 suits high-end electronic or battery conductors. Moreover, buyers should define thickness, width, coil ID/OD, slitting tolerance, edge condition and temper. For tighter widths, the slitting service pairs well with the Strip and Coil supply.

Copper Busbar and Flat Bar

Flat bar and busbar carry the main current path. Consequently, C11000 covers standard power distribution, while C10200 suits oxygen-free or high-reliability duty. Importantly, buyers should specify width, thickness, length, conductivity (%IACS), edge condition, hole pattern, bending and any plating. The Flat and Round Bar stock covers these shapes.

Copper Rod and Bar

Rod and bar feed machining and contact parts. For example, C11000 suits general machining, while C10200 and C10100 serve vacuum and electronic parts. In addition, define diameter, length, straightness, temper and machining allowance. For cut-to-length blanks, the laser cutting option can speed fabrication.

Copper Tube and Pipe

Tube and pipe lead HVAC, refrigeration, plumbing and heat exchanger work. Namely, C12200 covers most tube duty, while C12000 fits selected brazed or formed applications. Furthermore, buyers should state OD, wall thickness, length or coil size, application standard, cleanliness and end protection. The Copper Tube and Pipe range covers straight and coil forms.

Copper Wire and Custom Parts

Wire and machined parts close the list. So C11000 suits general conductive wire, while C10200 and C10100 cover high-conductivity or high-purity work. Finally, send a drawing with grade, tolerance, surface finish, plating and inspection method through the Copper Wire range.

Choose the Right Copper Grade by Industry

Application drives the safest grade choice. Therefore, this table maps common industries to forms, grades and the main procurement risk to control.

Specifications to Confirm Before Requesting a Quote

A vague request such as "please quote pure copper sheet" usually returns prices that cannot be compared. Therefore, a professional RFQ should define the following fields:

• Grade: C11000, C10200, C10100, C12200, C12000 or silver-bearing copper.
• Standard: ASTM, EN, JIS, GB or the project standard.
• Product form and dimensions: sheet, strip, busbar, rod, tube or wire, plus thickness, width, length, OD and wall thickness.
• Tolerance and temper: dimensional and flatness tolerance, plus soft (O60), half-hard (H02) or hard (H04).
• Conductivity and surface: %IACS if required, and mill, bright, polished, degreased or film-protected finish.
• Documents and terms: MTC type (EN 10204 3.1 or 3.2), CO, RoHS, REACH, Incoterms and destination port.

Because details drive accuracy, buyers can confirm tolerance bands with the Dimensional Tolerance Calculator and finishes with the Surface Finish Chart. In other words, the more precise the RFQ, the more reliable the quotation.

Understanding LME-Based Pricing for Copper from China

How a Copper Export Quotation Is Built

A copper quotation usually stacks several layers. First, it starts from a copper metal basis, often linked to LME Copper or a domestic reference. Next, it adds the processing fee, then cutting, slitting, drilling or machining cost. Finally, it adds surface protection, packing, inland freight, documentation, and ocean freight depending on Incoterms.

Questions Buyers Should Ask About Price

Because metal value moves daily, buyers should ask whether the quote is fixed or floating. Moreover, they should confirm when the LME basis is fixed: at order confirmation, at shipment, or over an agreed average. Also, compare the processing fee only when grade, form, size, tolerance, temper, packing and documents match.

A price far below normal copper value deserves caution. For example, possible reasons include the wrong grade, scrap-based material, missing documents or an unrealistic quotation. Therefore, verify the source, grade, MTC and payment terms before paying a deposit. To translate tonnage into unit cost, the Ton-to-Piece price tool helps buyers compare offers cleanly.

How to Vet a Chinese Pure Copper Supplier

Confirm Identity and Supplier Type

Start with business identity. Specifically, check the business license, export experience, registered scope, address and consistent bank and email domains. In China, the business license can be cross-checked through the National Enterprise Credit Information Publicity System.

Next, identify the supplier type, because a mill, a fabricator, a stockholder and a trading company serve different needs. For example, a capable fabricator or stockholder may suit cut-to-size sheet, slit strip, busbar or mixed-grade shipments better than a mill that prefers large single-grade runs.

Run Practical First-Order Checks

For a first order, request redacted MTC samples and photos or videos of stock, processing and packing. In addition, use third-party inspection for first or high-value orders, since SGS, Bureau Veritas, TÜV Rheinland and Intertek all operate in China. Finally, confirm export history to your destination and the exact packing method before shipment. The Quality Inspection workflow outlines what a pre-shipment check should cover.

How to Read a Chinese Copper Mill Test Certificate

EN 10204 3.1 vs 3.2 — The Distinction That Matters

International procurement should state which MTC type is required, because "please provide MTC" without a type is a common source of dispute. For reference, the EN 10204 standard defines four document types.

What Buyers Should Verify on the Certificate

An MTC should show the maker, grade, standard, heat number, dimensions, chemistry (Cu, O, P and impurity limits), temper and conductivity where required. So buyers should check that the heat number matches the labels, the grade matches the PO, and the chemistry suits the grade (for example, Cu ≥ 99.90% for C11000, ≥ 99.95% for C10200, and ≥ 99.99% for C10100).

However, an MTC is not a substitute for clear specifications, traceability and inspection. For new suppliers or critical service, third-party verification may still be necessary.

Need EN 10204 3.1 documentation, third-party inspection or seaworthy packing? Therefore, share your documentation requirements before production so the team can build them into the quotation.

Packing, Logistics and Incoterms for Copper Export Orders

Copper Is Valuable, Heavy and Easy to Damage

Because copper marks and dents easily, packing matters as much as the metal. For example, sheet and plate need pallets or cases with edge and moisture protection, while strip and coil need eye protection, moisture-proof wrapping and clear ID/OD marking. Meanwhile, busbar needs anti-oxidation paper and protection for holes and plated faces, and tube needs bundles, end caps and cleanliness control for refrigeration or heat exchanger duty.

Choose Incoterms by Experience and Risk

Incoterms should match the buyer's logistics capability. For instance, EXW gives control but adds coordination, while FOB suits experienced importers. By contrast, CIF or CIP often helps first-time buyers, since the seller arranges marine freight and insurance. Still, confirm loading weight with both supplier and forwarder, because destination road limits and shipping-line rules vary.

To plan freight and cost, buyers can estimate mass with the Metal Weight Calculator and copper density with the Metal Density Chart. In addition, the same Chinese New Year and Golden Week windows affect container booking, so plan well ahead.

Customs Documentation and HS Code Reference

Buyers should discuss classification with their own broker, because final duty treatment varies by country. As a starting point, however, the common HS code directions for copper are:

• 7407 — copper bars, rods and profiles.
• 7408 — copper wire.
• 7409 — copper plates, sheets and strip over 0.15 mm thick.
• 7410 — copper foil, 0.15 mm or less.
• 7411 — copper tubes and pipes.
• 7412 — copper tube or pipe fittings.

Documents commonly required include the commercial invoice, packing list, bill of lading and MTC. In addition, depending on destination and application, buyers may need a certificate of origin, a third-party inspection report, RoHS or REACH declarations, or PED documentation for pressure equipment into the EU. Therefore, confirm the final classification and import requirements before shipment.
