HS Code for Bronze billets

Bronze billets are classified under HS code 7403.22 because they represent unwrought forms of copper-tin base alloys. According to the General Rules of Interpretation (GRI) and the Harmonized System Explanatory Notes, heading 7403 covers refined copper and copper alloys in unwrought forms. Subheading 7403.22 specifically targets bronze, which is defined as an alloy of copper and tin, with or without other elements. Billets are semi-finished casting products, typically cylindrical or rectangular, intended for further processing such as extrusion or forging. Because they have not been worked beyond simple casting or sintering, they remain in the unwrought category. If these items were further processed into specific shapes like rods or bars through rolling or drawing, they would move to heading 7407. The classification depends heavily on the metallurgical composition, where tin must be the primary alloying element after copper. Customs authorities require precise chemical analysis to ensure the alloy meets the definition of bronze rather than brass or other copper alloys.

Products Included

• Cast bronze billets
• Sintered bronze blocks
• Unwrought bronze slabs
• Bronze extrusion billets
• Continuous cast bronze rounds

Common Misclassification

Bronze billets are frequently confused with bronze bars classified under HS code 7407.29. The distinction lies in the level of processing; 7403.22 is for unwrought forms (cast or sintered), while 7407 is for products that have been rolled, extruded, or drawn. Additionally, they may be misclassified under 7403.21 if the zinc content exceeds the tin content, which would define the material as brass rather than bronze.

FAQ

What is the HS code for bronze billets?

The HS code for bronze billets is 7403.22, which covers unwrought copper-tin base alloys.

What is the difference between a bronze billet and a bronze bar in HS classification?

A billet (7403.22) is an unwrought form produced by casting, whereas a bar (7407.29) is a wrought product that has undergone mechanical working like extrusion or rolling.
