HS Code for Zinc alloys
Zinc alloys are classified under HS code 7901.20, which falls within Chapter 79 (Zinc and articles thereof). Heading 7901 covers unwrought zinc, and the subheading 7901.20 is specifically designated for zinc alloys in primary forms such as ingots, blocks, or slabs. According to the Section XV notes of the Harmonized System, a metal is considered an alloy if the total weight of the alloying elements (such as aluminum, copper, or magnesium) exceeds the limits defined for "unalloyed" zinc. For zinc, this typically means the zinc content must be less than 97.5% by weight, or the content of any other single element must exceed the limits specified in the chapter notes. These alloys are primarily used in die-casting and galvanizing processes where specific mechanical properties, such as hardness or fluid flow, are required that pure zinc cannot provide.

Common Misclassification
Zinc alloys are frequently misclassified under HS code 7901.11 or 7901.12, which are reserved for unalloyed zinc (containing at least 97.5% zinc by weight). Importers must verify the mill test certificate to ensure the alloying elements meet the threshold for 7901.20. Another common error is using 7902.00, which is for zinc waste and scrap; while scrap may contain alloys, it is classified by its physical state as waste rather than as a primary unwrought product. Additionally, if the zinc alloy has been worked into bars, rods, or profiles, it must be classified under 7904.00 instead of the unwrought heading 7901.
FAQ
What is the HS code for zinc alloys?
The HS code for unwrought zinc alloys is 7901.20.
How is a zinc alloy defined for customs?
