Overview
This HTS category, 7304.29.41.60, specifically classifies seamless tubes and pipes made of iron or steel that are intended for use in drilling for oil or gas. These are further defined as casing, which is used to line the borehole to prevent collapse and contamination. Crucially, this particular subcategory applies to casing with a wall thickness of 12.7 mm or more.
The distinction from its sibling category, 7304.29.41.50, lies solely in the specified wall thickness. While both fall under "other" casing made of "other alloy steel" with an outside diameter exceeding 285.8 mm but not exceeding 406.4 mm, this classification requires a heavier wall construction. This thicker wall implies greater structural integrity and is often chosen for applications demanding enhanced pressure resistance or durability in challenging drilling environments.
As a leaf node, this HTS code represents the most specific classification for these particular oil and gas well casing pipes. Classification within this code is determined by the combination of their seamless construction, alloy steel composition, intended use in oil and gas drilling as casing, an outside diameter within the specified range (285.8 mm to 406.4 mm), and the critical wall thickness of 12.7 mm or greater.
