U.S. imports of unwrought zinc alloys (HS 790120) totaled $1.1M in April 2026, traded with 8 countries.
Last updated: April 2026 dataUnwrought zinc alloys — pre-alloyed ingots and slabs blending zinc with aluminum, copper, or magnesium — are a primary feedstock for pressure die casting in the automotive, hardware, and consumer electronics sectors. Mexico leads US imports of this material, followed by Peru and Italy, reflecting both proximity and established smelting capacity in those countries. Imports from China are subject to Section 301 tariffs, a factor that has influenced sourcing patterns toward Western Hemisphere and European suppliers.

The most commercially significant families are the ZAMAK alloys (zinc-aluminum-magnesium-copper), widely used in pressure die casting, and zinc-aluminum alloys used for hot-dip galvanizing baths. The specific alloy composition should be documented on the commercial invoice to support correct classification and to satisfy any applicable alloy-grade specifications required by the buyer.
CBP may request a mill certificate or metallurgical analysis confirming the alloying elements and their percentages. Providing this documentation proactively with the entry package reduces the risk of a hold or reclassification into a different HTS heading, particularly where the zinc content approaches the threshold that would place the material under a different chapter.
