HS Code for High purity zinc

High purity zinc is classified under HS code 7901.11. This code is part of Chapter 79, which covers zinc and articles thereof. Heading 7901 specifically addresses unwrought zinc, and subheading 7901.11 is reserved for zinc (not alloyed) containing by weight 99.99% or more of zinc. This grade is commercially known as Special High Grade (SHG) zinc. The classification is determined by the purity of the metal and its physical state as \"unwrought,\" meaning it is in primary forms like ingots, blocks, or slabs. The Harmonized System uses these purity thresholds to distinguish between high-grade industrial feedstock and lower-purity or alloyed metals. Classification follows the General Rules of Interpretation and the specific notes to Section XV regarding base metals.

Products Included

• Special High Grade (SHG) zinc ingots
• Unwrought zinc slabs (99.99% purity)
• Zinc jumbo blocks for continuous galvanizing
• High purity zinc anodes (unwrought)
• Zinc plates for remelting with 99.99% purity

Common Misclassification

High purity zinc is often confused with other grades of unwrought zinc. For instance, zinc containing less than 99.99% but at least 97.5% zinc is classified under 7901.12. Zinc alloys, which contain other elements added for specific properties, are classified under 7901.20. Additionally, if the zinc has been worked into semi-finished shapes like sheets, plates, or foil, it moves to headings 7903 through 7905. Zinc dust, powders, and flakes are also excluded from 7901.11 and are classified under 7903.

FAQ

What is the HS code for high purity zinc?

The HS code for unwrought, non-alloyed zinc with a purity of 99.99% or higher is 7901.11.

What does \"unwrought\" mean in this classification?

Unwrought refers to the primary form of the metal, such as ingots or blocks, produced by smelting or electrolysis, which has not yet been rolled, extruded, or forged into a finished shape.
