Last updated: August 2026 dataCopper chain and its component parts serve industrial, decorative, and marine applications where corrosion resistance and electrical conductivity are valued over the tensile strength of steel alternatives. Classification precision matters here because chain of base metals is distributed across several headings by metal type, and misidentifying alloy composition — particularly copper-zinc (brass) versus pure copper — can shift the applicable duty rate. Parts of chain, such as individual links or connecting hardware, are classified alongside the chain itself under this heading rather than as separate fittings.

Brass is a copper alloy, so brass chain generally falls within the copper chain heading rather than under a separate base-metal provision. However, the precise alloy composition and the applicable HTS schedule should be confirmed with a customs broker, as alloy thresholds can affect classification.
Parts of copper chain are explicitly covered alongside the chain itself under this heading, so individual links, clasps, and connectors made of copper or copper alloy are typically classified here rather than as general copper fittings or hardware.
