Products classified under HTS 7901.20.00.00
Zamak 3 Zinc Alloy Ingot
Zamak 3 is a high-pressure die casting zinc alloy containing approximately 96% zinc with aluminum, magnesium, and copper, supplied in unwrought ingot form for melting and casting. It falls under HTS 7901.20.00.00 as a zinc alloy where zinc predominates by weight and other elements exceed 2.5%. Used primarily in automotive and hardware die castings.
Zamak 5 Zinc Alloy Billets
Zamak 5 billets are unwrought forms of a zinc-based die casting alloy with enhanced strength due to higher aluminum and magnesium content, where zinc exceeds other elements by weight. Classified under HTS 7901.20.00.00 per chapter note (b) for zinc alloys. Ideal for precision castings in electronics and appliances.
ZA-8 Zinc-Aluminum Alloy Ingots
ZA-8 is a gravity casting zinc alloy ingot with about 91% zinc, 8% aluminum, and trace elements, provided in unwrought form for foundry use. It qualifies under HTS 7901.20.00.00 as zinc predominates and total other elements >2.5%. Commonly used for heavy-duty bearings and hardware.
ACuZinc 5 Zinc Alloy Pig
ACuZinc 5 pigs are pig-shaped unwrought castings of a zinc-copper-aluminum alloy for die casting, with zinc as the predominant metal per chapter definitions. Classified in HTS 7901.20.00.00 for zinc alloys used in plumbing fixtures and locks.
ZnAl4Cu3 Zinc Alloy Bars
ZnAl4Cu3 unwrought bars are cast zinc alloy stock with 4% aluminum and 3% copper for remelting in foundries, qualifying under HTS 7901.20.00.00 due to zinc predominance. Suitable for corrosion-resistant castings.
