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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for very high purity variants with minimal alloying
Meets unalloyed zinc definition if other elements <=2.5% by weight.
If alloyed primarily with copper exceeding zinc weight
Shifts to Chapter 72 if copper predominates, as zinc-copper alloys like brass are classified by base metal.
If aluminum predominates over zinc
Aluminum alloys heading applies when aluminum is the predominant metal by weight.

Import Tips & Compliance
• Use spectrographic analysis reports to prove zinc predominance and alloy status during entry
• Avoid common pitfall of declaring as scrap; unwrought alloys must be distinguished from 7902 waste/scrap
• Label shipments clearly as 'unwrought zinc alloys' to prevent misclassification
