U.S. imports of threaded copper screws, bolts & nuts (including iron/steel with copper heads) (HS 741533) totaled $5.1M in July 2026, traded with 32 countries.
Importers of Threaded Copper Screws, Bolts & Nuts (Including Iron/Steel with Copper Heads) paid $2.7M in duties in July 2026 — an effective duty rate of 57% on $4.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataThreaded screws, bolts, and nuts of copper — or of iron/steel fitted with copper heads — are classified across five 10-digit lines that distinguish wood screws (7415330500), Muntz or yellow metal bolts (7415331000), and general threaded fasteners subdivided by shank-thread diameter relative to 6mm (7415338010 and 7415338050), plus a residual line (7415338550). Muntz metal, a high-zinc brass alloy, has its own dedicated line due to its historical use in marine and architectural applications. Taiwan leads US supply, with China and India also significant. The diameter-based split between 7415338010 (over 6mm) and 7415338050 (under 6mm) is a common classification decision point for importers of general-purpose copper bolts.

Muntz metal is a high-zinc brass alloy (approximately 60% copper, 40% zinc) historically used for ship sheathing, condenser tubes, and architectural hardware due to its strength and marine corrosion resistance. Its dedicated line (7415331000) reflects its distinct alloy composition and long-standing commercial identity separate from standard brass or pure copper fasteners.
The shank-thread diameter of the bolt — not the head diameter or overall length — determines whether the article falls under 7415338010 (over 6mm) or 7415338050 (under 6mm). Importers should measure the nominal thread diameter as specified in the product standard or technical drawing and document that measurement in their classification records.
