U.S. imports of bronze plates, sheets & strip over 0.15 mm thick, in coils (HS 740931) totaled $9.6M in April 2026, traded with 12 countries.
Importers of Bronze Plates, Sheets & Strip Over 0.15 mm Thick, in Coils paid $5.3M in duties in April 2026 — an effective duty rate of 51% on $10.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCopper-tin alloy (bronze) flat-rolled products in coil form are used in bearing liners, spring components, electrical contacts, and marine hardware where tin content imparts hardness and wear resistance beyond what brass or refined copper can provide. The US schedule divides coiled bronze strip into three lines: 7409311000 for material 5 mm or more thick, 7409315000 for sub-5 mm coils at least 500 mm wide, and 7409319000 for narrower sub-5 mm material. Germany leads US imports, with the United Kingdom and China also among the top sources. Phosphor bronze and other tin-bearing grades are the most commercially significant varieties within this heading.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Phosphor bronze is a copper-tin base alloy in which phosphorus is added as a deoxidizer in small quantities, not as a principal alloying element. It therefore remains a copper-tin base alloy and classifies under heading 740931 (coiled) or 740939 (non-coiled) depending on presentation. The phosphorus content alone does not redirect it to the NESOI copper alloy headings.
A mill test certificate or material certification specifying the alloy designation (e.g., C510 phosphor bronze, C630 aluminum bronze) and confirming that tin is the principal alloying element after copper is the standard supporting document. If the alloy is aluminum bronze or silicon bronze, those are not copper-tin base alloys and would fall under the NESOI copper alloy headings rather than 740931.
