Overview

This HTS category, 7306.29.60.10, specifically classifies tubing made of iron or non-alloy steel that is imported with a coupling already attached. These are hollow profiles intended for use in drilling for oil or gas, often referred to as "casing" or "tubing" in the oil and gas industry. The presence of a pre-attached coupling is a key defining characteristic for classification within this specific subheading.

This subheading distinguishes itself from its sibling, 7306.29.60.50 ("Other"), by the explicit inclusion of the coupling. While the sibling category covers similar tubing of iron or non-alloy steel used in oil and gas drilling, it would apply to such tubing that is *not* imported with an attached coupling. The focus here is on the integrated nature of the product as received.

As this is a leaf node, there are no further subcategories. Therefore, classification under 7306.29.60.10 is final for oil and gas drilling tubing of iron or non-alloy steel that is imported with a pre-attached coupling. Importers should ensure that the material composition is consistent with iron or non-alloy steel and that the intended use is for oil and gas extraction operations.
