2620.11.00.00 - Hard zinc spelter

This HTS category, 2620.11.00.00, specifically classifies "Hard zinc spelter." Hard zinc spelter is a particular type of zinc alloy that is hard and brittle, often a byproduct of smelting processes. Its primary characteristic is its high zinc content, along with significant amounts of other metals like lead and cadmium, which contribute to its hardness. It is distinct from other zinc-containing residues and is typically used as a raw material in further metallurgical refining processes or for the production of specific alloys.

The distinction between this category and its sibling, 2620.19 ("Other"), lies in the specificity of the material. While 2620.19 covers a broader range of zinc-containing ashes, residues, and drosses, 2620.11.00.00 is reserved for the precisely defined hard zinc spelter. This means that only materials meeting the metallurgical and physical characteristics of hard zinc spelter will be classified here, whereas other zinc-rich waste materials would fall under the "other" category.

As this is a leaf node, there are no further subcategories to introduce. Therefore, the focus for classification within this code remains on accurately identifying the material as hard zinc spelter. Customs professionals should verify that the imported or exported material meets the established definitions and composition for hard zinc spelter to ensure correct classification and compliance with tariff regulations.
