Overview

This HTS category, 7304.29.20.30, specifically covers seamless tubes and pipes of iron or nonalloy steel that are used in drilling for oil or gas. These items are further defined as "casing" and must possess an outside diameter ranging from 215.9 mm to 285.8 mm, inclusive. The defining characteristic of this particular classification is a wall thickness that is strictly less than 12.7 mm.

It is crucial to distinguish this category from its sibling, 7304.29.20.40. The primary differentiator lies in the wall thickness. While this node encompasses casing with a wall thickness *less than* 12.7 mm, the sibling category applies to casing with a wall thickness of *12.7 mm or more*. Both categories share the same requirements regarding material (iron or nonalloy steel), application (oil and gas drilling), and outside diameter range.

As a leaf node within the HTS classification system, this category does not have further subcategories. Therefore, the classification is finalized based on the provided criteria: seamless casing of iron or nonalloy steel, used for oil and gas drilling, with an outside diameter between 215.9 mm and 285.8 mm, and crucially, a wall thickness less than 12.7 mm. Careful measurement of these physical attributes is essential for accurate classification and compliance with import/export regulations.
