7304.59.10.00 - Suitable for use in the manufacture of ball or roller bearings

This HTS classification covers seamless tubes and pipes, and hollow profiles, made from iron or steel, specifically those of a circular cross-section and manufactured from "other alloy steel" that is not otherwise specified. The key defining characteristic of this category is its suitability for use in the manufacture of ball or roller bearings. This implies that the tubes and pipes meet stringent specifications for material composition, dimensional accuracy, surface finish, and mechanical properties essential for bearing production.

At this level of the tariff schedule, "other alloy steel" distinguishes these articles from those made of non-alloy steel or specific types of alloy steel that may be classified under different headings. The "circular cross-section" differentiates them from other shapes of hollow profiles. The presence of the phrase "Suitable for use in the manufacture of ball or roller bearings" is a critical functional criterion that dictates classification, overriding purely physical attributes in some instances.

Since this is a leaf node, there are no further subcategories. Therefore, the classification hinges on correctly identifying the material as an alloy steel, confirming the circular cross-section, and most importantly, verifying its intended use in bearing manufacturing. Examples would include precision steel tubing used for bearing races or cages, where tight tolerances and specific alloy compositions are paramount.
