U.S. imports of plates, sheets & strip of other copper alloys (nesoi) over 0.15 mm thick (HS 740990) totaled $1.6M in April 2026, traded with 19 countries.
Importers of Plates, Sheets & Strip of Other Copper Alloys (NESOI) Over 0.15 mm Thick paid $640K in duties in April 2026 — an effective duty rate of 46% on $1.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Plates, Sheets & Strip of Other Copper Alloys (NESOI) Over 0.15 mm Thick imports of $1.6M in April 2026 ran 10% below the year-to-date monthly average of $1.8M.
Last updated: April 2026 dataBeryllium copper and other engineered copper alloys not classifiable as brass, bronze, cupro-nickel, or nickel-silver fall into this residual heading, which covers flat-rolled products used in aerospace spring contacts, precision tooling, and high-conductivity electronic substrates. The US schedule explicitly calls out beryllium copper at the 10-digit level — lines 7409901030, 7409905030, and 7409909030 — distinguishing it from other NESOI copper alloy flat-rolled products across the same thickness and width tiers. Germany and Japan lead US imports, reflecting their roles as precision alloy producers for electronics and aerospace supply chains. Beryllium copper handling may trigger occupational safety documentation requirements, as beryllium dust is a regulated substance under EPA and OSHA frameworks.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The US schedule carves out beryllium copper explicitly at the 10-digit level across all three dimension tiers: 7409901030 (5 mm or more thick), 7409905030 (sub-5 mm, 500 mm or wider), and 7409909030 (sub-5 mm, under 500 mm wide). All other copper alloy flat-rolled products not classifiable under a named alloy heading fall into the parallel NESOI lines. A mill certificate confirming beryllium as the principal alloying element is essential to support the beryllium copper classification.
While beryllium copper in solid, worked form does not typically trigger import permit requirements at the border, downstream handling — cutting, grinding, or machining — generates beryllium-containing dust subject to EPA and OSHA beryllium exposure regulations. Importers and end-users should ensure their facilities comply with applicable occupational health standards and that safety data sheets accompany shipments to downstream processors.
