About heading 7305
Other tubes and pipes (for example, welded, riveted or similarly closed), having circular cross sections, the external diameter of which exceeds 406.4 mm, of iron or steel
Heading 7305 covers welded or similarly closed iron or steel tubes and pipes with circular cross sections and an external diameter over 406.4 mm. It is split first by use, line pipe for oil or gas pipelines, casing for oil or gas drilling, and other pipes, then by weld method and by iron or nonalloy steel versus alloy steel.

Frequently asked questions
What is the HTS code for large oil or gas line pipe?
Longitudinally submerged arc welded line pipe of nonalloy steel with an external diameter over 406.4 mm but not over 609.6 mm is 7305.11.10.30, and the general (MFN) rate is Free. If the external diameter is over 609.6 mm, use 7305.11.10.60, and the general (MFN) rate is Free.
What is the duty on oil and gas well casing?
The general (MFN) rate for threaded or coupled casing of iron or nonalloy steel under 7305.20.20.00 is Free. The general (MFN) rate for other casing of iron or nonalloy steel under 7305.20.40.00 is Free.
How do I classify large welded alloy steel pipe?
For other welded pipe that is longitudinally welded, stainless steel pipe over 406.4 mm is 7305.31.60.10, and the general (MFN) rate is Free. Other alloy steel pipe in that group is 7305.31.60.90, and the general (MFN) rate is Free.
