HS Code for Copper alloy sheet

Copper alloy sheets are classified under HS code 7409.90 because they consist of copper alloys other than the specific categories of brass, bronze, cupro-nickel, or nickel silver, and possess a thickness exceeding 0.15mm. The General Rules for the Interpretation (GRI) of the Harmonized System dictate that products are classified based on their material composition and physical dimensions. Since these sheets are made of "other" copper alloys—such as beryllium copper or chromium copper—they fall into the residual category of heading 7409. The classification requires the product to be in a flat-rolled shape, whether in coils or not, and not to have the character of articles or products classified elsewhere. The 0.15mm threshold is a critical technical boundary; anything thinner would typically be classified as foil under heading 7410.

Products Included

• Beryllium copper sheets
• Chromium copper plates
• Zirconium copper flat-rolled products
• Tungsten copper alloy sheets
• Copper-zirconium alloy plates exceeding 0.15mm thickness

Common Misclassification

This code is frequently confused with HS code 7409.11 or 7409.19, which are reserved for refined copper rather than copper alloys. Additionally, importers often mistakenly use 7409.21 (copper-zinc base alloys/brass) or 7409.31 (copper-tin base alloys/bronze) for specialty alloys. Another common error involves HS code 7410.22, which covers copper alloy foil; the distinction rests entirely on the thickness, where 7410 is for items 0.15mm or thinner.

FAQ

What is the HS code for copper alloy sheet?

The HS code for copper alloy sheets (excluding brass, bronze, and cupro-nickel) with a thickness exceeding 0.15mm is 7409.90.

How is a sheet distinguished from a foil in the HS system?

Under Chapter 74, any flat-rolled product with a thickness of 0.15mm or less is classified as foil (7410), while products thicker than 0.15mm are classified as plates, sheets, or strip (7409).
