About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification, 7304.39.00.36, specifically covers seamless tubes and pipes of iron or nonalloy steel that have a circular cross-section and a wall thickness measuring less than 12.7 mm. These products are distinct from those with thicker walls; they fall within a broader category of "Other" seamless tubes and pipes of circular cross-section made from iron or nonalloy steel, but are further refined by their specific wall dimension.

The crucial distinguishing factor for this subcategory is the wall thickness. Unlike sibling categories such as 7304.39.00.40, which covers wall thicknesses of 12.7 mm or more but less than 19 mm, and 7304.39.00.44, for wall thicknesses of 19 mm or more, this classification is exclusively for tubes and pipes with walls *thinner* than 12.7 mm. This precise measurement is a key determinant for accurate customs declaration and duty assessment, ensuring correct placement within the tariff schedule.

As a leaf node, 7304.39.00.36 does not have further subdivisions. Therefore, classification within this category relies solely on meeting the specified criteria: being a seamless tube or pipe of iron or nonalloy steel, having a circular cross-section, and importantly, possessing a wall thickness strictly less than 12.7 mm. Examples would include various types of piping used in fluid conveyance where thinner wall profiles are suitable for lower pressure applications or where weight reduction is a consideration.
