7304.29.50 - Of iron or nonalloy steel

This HTS category, 7304.29.50, specifically classifies tubing made from iron or nonalloy steel that is used in drilling operations for oil or gas. These are seamless tubes designed for the demanding environments of exploration and extraction. They are distinct from casing and drill pipe, which serve different functions within the drilling process, and also from other types of tubing not intended for this specific industry application.

Within this category, further distinctions are made based on the outside diameter of the tubing. This allows for more precise classification and helps to differentiate products based on their intended use and the specifications required for different drilling scenarios. The subsequent subcategories are defined by specific diameter ranges, ensuring that each segment of the market for oil and gas drilling tubing is accurately accounted for.

The subcategories under 7304.29.50 are: tubing with an outside diameter not exceeding 114.3 mm; tubing with an outside diameter exceeding 114.3 mm but less than 215.9 mm; tubing with an outside diameter of 215.9 mm or more but not exceeding 406.4 mm; and tubing with an outside diameter exceeding 406.4 mm. This granular breakdown facilitates accurate tariff application based on the physical dimensions of the tubular goods.
