HS Code for Refined unwrought copper

Refined unwrought copper is classified under HS code 740319. Heading 7403 covers refined copper and copper alloys in unwrought forms, such as ingots, blocks, or slabs. The classification within this heading is highly specific based on the shape and purity of the copper. Subheading 740311 is for cathodes and sections of cathodes, 740312 is for wire-bars, and 740313 is for billets. HS code 740319 serves as the residual category for all other forms of refined unwrought copper that do not fit into those specific shapes. To be classified as "refined copper," the material must contain at least 99.85% copper by weight, or at least 97.5% copper provided that no single other element exceeds specific limits defined in the Chapter 74 notes. This classification is critical for the metals industry to distinguish between high-purity refined metal and unrefined or alloyed copper.

Products Included

• Refined copper ingots
• Refined copper cakes
• Refined copper slabs
• Refined copper blocks
• Unwrought refined copper shapes (not cathodes or billets)
• Refined copper pellets for melting

Common Misclassification

Refined unwrought copper is often misclassified under 740311 if the customs broker assumes all unwrought refined copper is a cathode. It is also frequently confused with copper alloys (740321 to 740329); however, if the copper content meets the "refined" definition, it must stay in the 74031x series. Another error is classifying it as copper waste and scrap (740400), which is only for worn-out or damaged copper items, not for newly refined unwrought metal.

FAQ

What is the HS code for refined unwrought copper?

The HS code for refined unwrought copper (other than cathodes, wire-bars, or billets) is 740319.

What defines copper as "refined" in the HS system?

Refined copper must have a copper content of at least 99.85% by weight, or meet specific impurity thresholds defined in the legal notes of Chapter 74.
