7306.30.50.35 - Tube and pipe hollows for redrawing

This HTS classification, 7306.30.50.35, pertains to "Other" tubes and pipes of iron or non-alloy steel that are welded, have a circular cross-section, and possess a wall thickness of 1.65 mm or more. Specifically, this subcategory covers items that are not imported with a coupling already attached. The "Other" designation at this granular level indicates that while these tubes meet the broader criteria of welded, circular, and wall thickness, they do not fit into any more specific, pre-defined sub-classifications within this particular branch of the tariff schedule.

The key distinguishing factor for this category, when compared to its sibling "Imported with coupling," lies in the presence or absence of a coupling. Goods classified here are those without any pre-attached coupling mechanism. This distinction is crucial for customs purposes, as the inclusion of a coupling can alter the product's perceived function and commercial presentation, potentially influencing duty rates or import regulations.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the classification ends with the specific criteria outlined: welded, circular, iron or non-alloy steel, wall thickness of 1.65 mm or more, an outside diameter not exceeding 114.3 mm, and not imported with a coupling. This detailed set of physical and conditional attributes ensures precise identification of the imported goods for customs and trade purposes.
