Overview

This HTS category, 7315.89.30.00, specifically classifies chain and parts thereof, made of iron or steel, that are "other" than those already specified, and feature links with essentially round cross-sections. The defining characteristic of this subcategory is that the diameter of these round cross-sections exceeds 8 millimeters. This means the chains classified here are generally of a more robust and heavy-duty nature, designed for applications requiring greater strength and load-bearing capacity compared to smaller diameter chains.

The critical differentiator for this classification lies in the dimension of the chain links. While the parent category covers "other chain" with essentially round cross-section links, this specific subcategory is distinguished from its sibling, 7315.89.10.00, by the diameter of those links. Chains classified under 7315.89.10.00 will have links with a round cross-section measuring not over 8 mm in diameter, whereas this category exclusively covers those exceeding that threshold. This diameter measurement is the primary physical characteristic used for classification at this level.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Therefore, the classification process for goods falling under 7315.89.30.00 is complete once the criteria of being an iron or steel chain with essentially round cross-section links, and a diameter over 8 mm, are met. Examples of products that would fall here include heavy industrial chains for towing, lifting, anchoring, or heavy machinery operation where significant strength is paramount.
