7411.10.10.30 - Having an outside diameter of 6 mm or more but not exceeding 16 mm, in coils on spools

This HTS category, 7411.10.10.30, specifically classifies seamless tubes and pipes made of refined copper that possess an outside diameter ranging from 6 mm up to and including 16 mm, and which are presented for shipment in coils wound onto spools. The defining characteristics for this sub-classification are the precise dimensional parameters of the tubing and its packaging format.

Distinguishing this category from its sibling, 7411.10.10.90, which covers "Other" seamless tubes and pipes of refined copper, is crucial. The "Other" category encompasses all seamless refined copper tubes and pipes that do not meet the specific diameter range (6 mm to 16 mm outside diameter) or the coil-on-spool packaging requirement stipulated in this classification. Therefore, any seamless refined copper tube outside this diameter range, or presented in a different form such as straight lengths or on different types of reels, would fall under the sibling category.

As this is a leaf node within the HTS classification system, there are no further subcategories branching from 7411.10.10.30. Classification decisions at this level are final based on the specified diameter and packaging criteria. This ensures precise identification of specific types of seamless refined copper tubing for customs purposes.
