Overview
This HTS classification covers welded tubes and pipes of iron or steel, specifically those of stainless steel with a circular cross-section. The defining characteristic for this category is a wall thickness measuring 1.65 millimeters or greater. These tubes are generally intended for specialized industrial applications such as boilers, superheaters, heat exchangers, condensers, refining furnaces, and feedwater heaters, and may be manufactured through various welding processes.
Distinguishing this category from its sibling, "Other, cold-drawn or cold-rolled (cold- reduced)," lies in the manufacturing process and subsequent dimensional tolerances. While both fall under "Other, welded, of circular cross section, of stainless steel," this classification specifically addresses welded tubes and pipes of the specified wall thickness, whereas the sibling focuses on items subjected to cold reduction processes which typically result in tighter dimensional controls and smoother surface finishes.
As this node represents a leaf in the HTS classification structure, there are no further subcategories. Therefore, classification within this specific code (7306.40.50.15) relies on meeting all preceding criteria: being a welded tube or pipe of iron or steel, made of stainless steel, having a circular cross-section, and possessing a wall thickness of 1.65 mm or more. The descriptive note regarding suitability for specific industrial equipment further guides classification, although the physical dimensions and material are the primary determinants.
