7304.59 - Other:
Sub-classifications
Overview
This HTS category, 7304.59, encompasses tubes, pipes, and hollow profiles of iron or steel that are seamless and of circular cross-section, but are not made from cast iron or other alloy steels. The defining characteristic of this "Other" category is that the tubes and pipes are not subjected to cold-drawing or cold-rolling processes as described in the sibling category 7304.51. Therefore, this section focuses on seamless, circular, non-alloy steel hollow profiles that do not meet the specific processing criteria of the preceding subheadings.
The distinction from sibling categories is crucial for accurate classification. While 7304.51 specifically addresses items that have undergone cold-forming, 7304.59 covers those that have not. This means items classified here would typically be produced through methods like hot rolling or extrusion, without subsequent cold reduction. The absence of the cold-working designation is the primary differentiator, impacting physical properties and permissible tolerances, which are key considerations in international trade.
This category is further subdivided to provide more granular classification. The primary subcategory, 7304.59.10.00, is designated for seamless, circular, non-alloy steel hollow profiles that are specifically engineered and suitable for use in the manufacture of ball or roller bearings. The subsequent "Other" subdivision under 7304.59 captures all remaining seamless, circular, non-alloy steel tubes, pipes, and hollow profiles that do not meet the specific criteria for bearing manufacturing.
