Overview
This HTS category, 7304.29.61.30, specifically classifies seamless tubing made from alloy steel, intended for use in drilling for oil or gas. A key defining characteristic of this tubing is its wall thickness, which must exceed 9.5 mm. This classification is relevant for tubing where the primary function and material composition align with oil and gas extraction operations, and the robust wall thickness indicates a requirement for higher pressure or structural integrity.
This category is distinguished from its sibling, 7304.29.61.15, by the specific wall thickness criterion. While both are seamless alloy steel tubing for oil and gas drilling and have an outside diameter not exceeding 114.3 mm, 7304.29.61.15 covers tubing with a wall thickness of 9.5 mm or less. Therefore, the critical differentiator for this particular code is the *greater* than 9.5 mm wall thickness, suggesting applications demanding enhanced strength and durability.
As this is a leaf node in the HTS classification system, there are no further subcategories under 7304.29.61.30. Classification decisions at this level rely entirely on the precise physical attributes (wall thickness) and intended application (oil and gas drilling) as outlined in the parent categories and the specific description for this code.
