7306.40.50 - Having a wall thickness of 1.65 mm or more
Sub-classifications

7306 4050 05
Overview
This HTS category, 7306.40.50, specifically classifies welded tubes, pipes, and hollow profiles made of iron or steel, which have a circular cross-section and are constructed from stainless steel. The defining characteristic for inclusion in this subcategory is a wall thickness that measures 1.65 millimeters or greater. These are typically robust tubular products intended for applications where significant structural integrity or fluid containment under pressure is required.
Distinguishing this category from its sibling, 7306.40.10, hinges solely on the wall thickness. While both cover welded, circular, stainless steel tubes, pipes, and hollow profiles, 7306.40.10 encompasses those with a wall thickness *less than* 1.65 mm. Therefore, this current category is reserved for the heavier-gauge stainless steel variants.
The subcategories under 7306.40.50 further refine the classification based on the specific alloy composition of the stainless steel. The option 7306.40.50.05 is designated for products made of "high-nickel alloy steel," indicating a premium grade stainless steel with a significant nickel content. All other stainless steel variants that meet the circular cross-section, welded construction, and wall thickness of 1.65 mm or more, but are not specifically high-nickel alloy steel, fall into the "Other" subdivision.
