Last updated: August 2026 dataBrass tubes and pipes — copper-zinc base alloys — serve heat exchangers, musical instruments, architectural trim, and fluid-handling systems where machinability and moderate corrosion resistance outweigh the need for pure copper's conductivity. The heading splits into seamless (7411211000) and non-seamless (7411215000) forms, a distinction that affects both duty rates and end-use suitability. Canada leads US imports under this heading, with South Korea and China also supplying the market.

Seamless tube is produced by extrusion, drawing, or piercing without a longitudinal weld seam. Non-seamless (welded) brass tube is formed from strip and joined along a seam. The manufacturing method — confirmed by mill test reports or producer documentation — is the determining factor. Seamless and non-seamless lines carry separate 10-digit codes and may have different duty rates.
Yes — visually similar dimensions can lead to misclassification. A mill certificate specifying the alloy composition (zinc content typically 5–40% for brass) is the definitive document. Customs may request laboratory analysis if the certificate is absent or ambiguous. Refined copper tube (7411.10) and brass tube (7411.21) are separate subheadings with distinct duty treatment, so accurate alloy documentation is essential.
