HS Code for High purity magnesium

High purity magnesium is classified under HS code 8104.11. This code is specifically designated for unwrought magnesium that contains at least 99.8% magnesium by weight. In the context of the Harmonized System, \"unwrought\" refers to primary forms such as ingots, blocks, or slabs that have been produced by casting or sintering and have not been further worked. The high purity requirement (99.8%) is a strict threshold; if the magnesium content is lower, it is considered an alloy or a lower-grade metal. This material is essential in specialized industries, including aerospace and chemical synthesis, where impurities can compromise the structural integrity or chemical reactivity of the final product. The classification is governed by the Section XV notes and the specific subheading text for Chapter 81.

Products Included

• Unwrought magnesium ingots (99.8% purity or higher)
• High purity magnesium slabs and billets
• Magnesium T-bars and pigs for remelting
• Ultra-pure magnesium crystals for vacuum deposition
• Refined magnesium blocks for alloying purposes

Common Misclassification

High purity magnesium is often confused with magnesium alloys, which are classified under 8104.19. Alloys contain less than 99.8% magnesium and include other elements like aluminum or zinc to enhance specific properties. Another common error is classifying magnesium waste and scrap under this code; scrap is correctly classified under 8104.20. Additionally, magnesium raspings, turnings, and granules are classified under 8104.30, even if they are of high purity, because they are not in \"unwrought\" primary forms.

FAQ

What is the HS code for high purity magnesium?

The HS code for unwrought magnesium containing at least 99.8% magnesium by weight is 8104.11.

Is magnesium wire included in this HS code?

No, magnesium wire is considered a \"wrought\" product and is classified under 8104.90, as 8104.11 is strictly for unwrought primary forms.
