Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refined copper alloy, straight lengths
Non-coiled brass plates/sheets/strip ≥5mm thick use 7407.12 for refined copper-zinc alloys.
If thickness <5mm but >0.15mm
Thinner brass coils within chapter 74 stay in 7409.21 but different statistical suffix.
If further manufactured into articles like fittings
Finished brass articles from these coils classify under Chapter 74 Article headings like 7419.

Import Tips & Compliance
• Submit EN 12420 or ASTM B124 certification for alloy grade to confirm brass composition
• Measure coil thickness at multiple points; variations could trigger reclassification if average <5mm
• Avoid declaring as scrap; clean mill product status requires proof of production process
