SITCSection 6
U.S. imports of zinc alloys, unwrought (SITC 68612) totaled $1.1M in April 2026, traded with 8 countries.
Importers of Zinc Alloys, Unwrought paid $4K in duties in April 2026 — an effective duty rate of 4.6% on $94K in dutiable value, based on actual customs collections rather than the published tariff schedule. Zinc Alloys, Unwrought imports of $1.1M in April 2026 ran 14% above the year-to-date monthly average of $963K.
Last updated: April 2026 dataUnwrought zinc alloys — including the ZAMAK family (zinc-aluminum-magnesium-copper), zinc-aluminum alloys for die casting, and zinc-copper alloys — are engineered feedstocks for pressure die casting of automotive components, hardware, electrical connectors, and consumer goods. Alloy composition, particularly aluminum content, determines fluidity, strength, and dimensional stability in the die-casting process, making chemistry certification a commercial and classification necessity. Demand is closely tied to automotive production cycles, where zinc die castings are valued for their ability to hold tight tolerances at high production volumes.

The ZAMAK alloys (Nos. 2, 3, 5, and 7) are the most widely used, differing in aluminum, magnesium, and copper content to balance strength, ductility, and castability. Zinc-aluminum alloys with higher aluminum content (ZA-8, ZA-12, ZA-27) offer greater strength for structural die castings. Each alloy family has specific ingot chemistry specifications, and buyers should require a certificate of analysis confirming composition against the relevant ASTM or equivalent standard.
A producer's certificate of analysis showing the percentage of each alloying element (aluminum, copper, magnesium, and impurities such as lead, cadmium, and tin) is the standard supporting document. This not only confirms classification as an alloy rather than unalloyed zinc but also satisfies quality-assurance requirements for die-casting customers who must meet ASTM B86 or equivalent specifications.
