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 category encompasses welded tubes, pipes, and hollow profiles made of iron or steel, specifically of circular cross-section and composed of other alloy steel. These items are characterized by having a wall thickness of 1.65 mm or greater and do not fall under the "cold-drawn or cold-rolled (cold-reduced)" designation. The primary purpose of these articles is for use in demanding thermal applications such as boilers, superheaters, heat exchangers, condensers, refining furnaces, and feedwater heaters, irrespective of whether they have undergone a cold-drawing process.

This classification distinguishes itself from its sibling category (7306.50.50.30) by the method of manufacture. While this node covers welded tubes of other alloy steel with a wall thickness of 1.65 mm or more, the sibling category specifically addresses those that have been cold-drawn or cold-rolled (cold-reduced). Therefore, the key differentiator lies in whether the final shaping process involves cold reduction techniques.

As this is a leaf node within the HTS classification structure, there are no further subcategories. Classification at this level is determined by the material (other alloy steel), the manufacturing method (welded), the cross-sectional shape (circular), the wall thickness (1.65 mm or more), and the intended application in specialized thermal equipment.
