Product classification
HS code for Bronze strip coil: 7409.31
Copper, strip, of a thickness exceeding 0.15mm, of copper-tin base alloys (bronze), in coils.
Classification of bronze strip coil under HS 7409.31
The Harmonized System (HS) code 740931 specifically classifies copper strip of a thickness exceeding 0.15mm, made from copper-tin base alloys (bronze), and presented in coils. This classification is precise, focusing on the material composition (bronze, a copper-tin alloy), the physical form (strip), its dimensions (thickness greater than 0.15mm), and its packaging (in coils). The "copper-tin base alloys" component is critical, distinguishing it from other copper alloys. The "strip" form implies a product with a relatively high width-to-thickness ratio, suitable for further processing such as stamping or forming. The "in coils" aspect indicates a continuous length, typical for industrial applications requiring automated feeding.

Codes often confused with 7409.31
Common mistake. Common misclassifications often arise from confusion with other copper alloys or forms. HS code 740911 covers strip of refined copper, in coils, which differs significantly in material composition from bronze. HS code 740940 pertains to strip of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver), also in coils, which are distinct in their alloying elements. Furthermore, HS code 740921 covers strip of copper-zinc base alloys (brass), in coils, which is a common error due to the similar appearance and application of brass and bronze. The key differentiator for 740931 is the specific copper-tin alloy composition.
Top exporters and importers of HS 740931 (the code used for bronze strip coil), 2025
In 2025, the largest exporter of HS 740931 (the code used for bronze strip coil) in UN Comtrade data was Germany, with 41% of world exports; the largest importer in UN Comtrade data was the United States, with 16% 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 that did not report are estimated from what other countries recorded trading with them. 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. 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 bronze strip coil
What is the HS code for Bronze strip coil?
The HS code for Bronze strip coil is 740931 (Copper; strip, of a thickness exceeding 0.15mm, of copper-tin base alloys (bronze), in coils). The HS code for bronze strip coil, specifically those made from copper-tin base alloys with a thickness exceeding 0.15mm and presented in coils, is 740931.
How do I classify Bronze strip coil for customs?
Bronze strip coil is classified under HS code 740931 — Copper; strip, of a thickness exceeding 0.15mm, of copper-tin base alloys (bronze), in coils. This is a 6-digit subheading level code.
What distinguishes bronze strip from brass strip for HS classification?
For HS classification, bronze strip (740931) is primarily a copper-tin base alloy, whereas brass strip (740921) is a copper-zinc base alloy. This fundamental difference in primary alloying elements dictates their respective HS codes.
Which countries are the top exporters of bronze strip coil (HS 740931)?
In 2025, the top exporters of HS 740931 (the code used for bronze strip coil) in UN Comtrade data were Germany ($331M, 41% of world exports), Japan ($139M) and China ($124M). World exports came to about $804M, 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.
