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, 7304.59.80.40, specifically designates seamless tubes, pipes, and hollow profiles made from iron or steel, which are of a circular cross-section and composed of alloy steel. Crucially, these items are further defined by their substantial wall thickness, requiring it to be 19 mm or greater. The outer diameter of these products falls within the range exceeding 114.3 mm but less than 190.5 mm.

The distinguishing feature of this category lies in its precise wall thickness requirement. It is differentiated from sibling category 7304.59.80.30, which covers similar alloy steel tubes with wall thicknesses less than 12.7 mm, and from 7304.59.80.35, which encompasses those with wall thicknesses of 12.7 mm or more but less than 19 mm. Therefore, only alloy steel tubes with an outer diameter between 114.3 mm and 190.5 mm, and a wall thickness of precisely 19 mm or more, will fall under this specific code.

As this is a leaf node within the HTS structure, there are no further subdivisions. Classification to this level signifies a complete and specific identification of the product based on its seamless construction, material composition (alloy steel), circular cross-section, outer diameter range, and substantial wall thickness. Examples of goods that might be classified here include heavy-duty industrial piping for high-pressure applications or structural components requiring significant wall integrity.
