Product classification
HS code for Copper alloy sheet: 7409.90
Copper, plates, sheets and strip, of a thickness exceeding 0.15mm, of copper alloys (other than copper-zinc base alloys, copper-tin base alloys, copper-nickel base alloys or copper-nickel-zinc base alloys).
Classification of copper alloy sheet under HS 7409.90
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.

Codes often confused with 7409.90
Common mistake. 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.
Top exporters and importers of HS 740990 (the code used for copper alloy sheet), 2025
In 2025, the largest exporter of HS 740990 (the code used for copper alloy sheet) in UN Comtrade data was Japan, with 28% of world exports; the largest importer in UN Comtrade data was China, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about copper alloy sheet
What is the HS code for Copper alloy sheet?
The HS code for Copper alloy sheet is 740990 (Copper; plates, sheets and strip, of a thickness exceeding 0.15mm, of copper alloys (other than copper-zinc base alloys, copper-tin base alloys, copper-nickel base alloys or copper-nickel-zinc base alloys)). The HS code for copper alloy sheets (excluding brass, bronze, and cupro-nickel) with a thickness exceeding 0.15mm is 7409.90.
How do I classify Copper alloy sheet for customs?
Copper alloy sheet is classified under HS code 740990 — Copper; plates, sheets and strip, of a thickness exceeding 0.15mm, of copper alloys (other than copper-zinc base alloys, copper-tin base alloys, copper-nickel base alloys or copper-nickel-zinc base alloys). This is a 6-digit subheading level code.
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).
Which countries are the top exporters of copper alloy sheet (HS 740990)?
In 2025, the top exporters of HS 740990 (the code used for copper alloy sheet) in UN Comtrade data were Japan ($290M, 28% of world exports), Germany ($261M) and South Korea ($90M). World exports came to about $1.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
