7306.40.10.90 - Other

This HTS category specifically classifies welded tubes, pipes, and hollow profiles made of iron or steel that have a circular cross-section and are constructed from stainless steel. A key defining characteristic is their wall thickness, which must be less than 1.65 millimeters. These are typically used in applications where lightweight yet corrosion-resistant tubing is required, such as in certain mechanical components, fluid conveyance systems, or as structural elements in various industries.

This subcategory is distinguished from its sibling category, "Containing more than 0.5 percent by weight of nickel," by the absence of a specific nickel content requirement. While stainless steel inherently contains nickel, this classification focuses solely on the wall thickness criterion for welded, circular cross-section stainless steel tubes, pipes, and profiles. The sibling category would apply to similar items that also meet the nickel percentage threshold, potentially indicating specific material compositions or intended uses associated with higher nickel content.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification within this specific code relies entirely on meeting the defined criteria: welded construction, circular cross-section, stainless steel material, and a wall thickness under 1.65 mm. Accurate measurement of the wall thickness is the primary determinant for assigning goods to this classification.
