2603.00.00.30 - Zinc content

This HTS category, 2603.00.00.30, specifically addresses the classification of zinc content derived from copper ores and concentrates. It pertains to the elemental zinc present within these mineral products, which is a crucial component for subsequent extraction and processing. The classification is activated when zinc is the primary element of interest or a significant co-product being accounted for within the context of copper ore or concentrate trade.

Distinguishing this category from its siblings is essential for accurate customs declarations. While 2603.00.00.10 focuses on the copper content itself, and 2603.00.00.20, 2603.00.00.40, and 2603.00.00.50 denote lead, silver, and gold content respectively, this classification (2603.00.00.30) isolates the zinc component. This implies that the declaration is for the value or quantity of zinc present, potentially as a byproduct or a key element in a complex ore, distinct from the primary copper value.

As a leaf node, 2603.00.00.30 does not have further subdivisions. Therefore, classification within this code relies on clearly identifying the zinc content as a component of the copper ore or concentrate being imported or exported. Practical classification will involve analyzing assay reports and other documentation that quantifies the percentage or mass of zinc present in the shipment, ensuring it is correctly reported according to customs regulations.
