U.S. imports of master alloys of copper (HS 740500) totaled $1.8M in July 2026, traded with 13 countries.
Master Alloys of Copper imports of $1.8M in July 2026 ran 225% above the year-to-date monthly average of $544K.
Last updated: July 2026 dataCopper master alloys are intermediate metallurgical products — concentrated blends of copper with one or more alloying elements — used to introduce precise chemistry into copper and copper-alloy melts during foundry and casting operations. The US schedule distinguishes phosphorus-bearing master alloys containing 5–15% phosphorus (7405001000), beryllium copper master alloy (7405006030), and all other types (7405006050). Belgium leads US supply, with Kazakhstan, Italy, India, and Germany also significant sources. Beryllium-containing grades warrant particular attention to occupational safety and handling regulations given beryllium's toxicological profile.

Phosphor copper master alloys in the 5–15% phosphorus range are specifically used as deoxidizers and brazing alloy components in copper processing. The narrow phosphorus range defines the tariff line; alloys outside that range or containing different primary alloying elements fall under the NESOI lines. Importers should provide mill certificates confirming elemental composition to support classification.
Yes. Beryllium is a regulated toxic substance, and beryllium-containing alloys are subject to EPA and OSHA requirements governing handling, labeling, and workplace exposure. While there is no import permit requirement specific to beryllium copper master alloys, importers and downstream users must comply with applicable hazardous materials regulations, and proper safety data sheets should accompany shipments.
