Overview

This HTS category, 7304.29, encompasses seamless tubes, pipes, and hollow profiles made of iron or steel, specifically those used in drilling for oil or gas, but which are neither drill pipe of stainless steel (7304.22) nor other drill pipe (7304.23), and are also not classified under the "other, of stainless steel" provision (7304.24). Essentially, this residual category captures seamless steel drilling-related tubular goods that do not meet the more specific criteria of the preceding subheadings.

The primary distinction for classification within 7304.29 lies in its exclusion of explicitly defined drill pipe and stainless steel variants, as well as general stainless steel tubular goods not intended for oil and gas drilling. This code therefore functions as a catch-all for oil and gas drilling pipes, casing, and tubing made from non-stainless steel alloys or with specifications that fall outside the more narrowly defined categories.

Within this category, further distinctions are made between casing and tubing. Casing refers to larger diameter pipes used to line the borehole, preventing collapse and isolating different geological formations. Tubing, conversely, is generally of smaller diameter and is inserted within the casing to transport oil or gas to the surface. Understanding the specific application and dimensions will be crucial for correctly classifying goods under these sub-classifications.
