HS Code for Refined copper billets

Refined copper billets are classified under HS code 7403.13. Billets are a specific form of unwrought refined copper, typically produced by continuous casting or by casting into molds. They are characterized by their solid cylindrical shape and are primarily used as the starting material for the extrusion of copper tubes, pipes, and rods. Under the Harmonized System, Chapter 74 Note 1(a) defines refined copper based on specific purity thresholds (minimum 99.85% copper or specific impurity limits). Heading 7403 covers unwrought forms, and 7403.13 is the specific subheading for billets. Because these items are cast and have not been subjected to further mechanical working like rolling or drawing, they remain in the unwrought category rather than being classified as semi-finished products.

Products Included

• Refined copper billets (cylindrical casting)
• Unwrought copper logs for extrusion
• Cast copper cylinders of refined copper
• Refined copper extrusion billets
• Unworked cylindrical copper castings

Common Misclassification

Refined copper billets are frequently misclassified under HS code 7407.10, which covers refined copper bars and rods. The distinction lies in the manufacturing process: 7403.13 is for "unwrought" (cast) billets, while 7407.10 is for products that have been "worked" (rolled, extruded, or drawn). If the cylindrical shape has been further processed to achieve precise dimensions or improved grain structure through mechanical means, it is no longer a billet. Another error is using 7403.19, which is a residual category for other unwrought shapes like slabs or cakes. Billets must be cylindrical to qualify for 7403.13. Lastly, if the billet is made of a copper alloy (e.g., brass), it must be classified under 7403.21-29.

FAQ

What is the HS code for copper billets?

Refined copper billets are classified under HS code 7403.13.

What is the difference between a billet and a rod?

A billet (7403.13) is an unwrought, cast product used as a raw material, whereas a rod (7407.10) is a semi-manufactured product that has been rolled or extruded from a billet.
