Seamless Steel Pipe HS Code List (HS 7304)
Heading 7304: Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel.
The subheadings below follow the HS 2022 six-digit structure. National tariffs add further digits; see “Does the HS Code Differ by Country?” below.
| Category | HS code (6-digit) | Description |
| Carbon and non-alloy steel (general-purpose tubes) | 7304.31 | Circular cross-section, of iron or non-alloy steel, cold-drawn or cold-rolled |
| 7304.39 | Circular cross-section, of iron or non-alloy steel, other (not cold-drawn or cold-rolled) | |
| Stainless steel (general-purpose tubes) | 7304.41 | Circular cross-section, of stainless steel, cold-drawn or cold-rolled |
| 7304.49 | Circular cross-section, of stainless steel, other | |
| Other alloy steel (general-purpose tubes) | 7304.51 | Circular cross-section, of other alloy steel, cold-drawn or cold-rolled |
| 7304.59 | Circular cross-section, of other alloy steel, other | |
| Line pipe for oil or gas pipelines | 7304.11 | Line pipe, of stainless steel |
| 7304.19 | Line pipe, other than of stainless steel | |
| Casing and tubing for oil or gas drilling | 7304.24 | Casing and tubing, of stainless steel |
| 7304.29 | Casing and tubing, other than of stainless steel | |
| Drill pipe for oil or gas drilling | 7304.22 | Drill pipe, of stainless steel |
| 7304.23 | Drill pipe, other than of stainless steel | |
| Other seamless products | 7304.90 | Other seamless tubes, pipes and hollow profiles of iron or steel |
In this table, “general-purpose” means round tubes other than the line pipe and the oil and gas casing, tubing and drill pipe covered by 7304.11 to 7304.29.
Seamless carbon steel pipe is usually classified under the non-alloy subheadings (7304.31 or 7304.39) when it is a general-purpose tube. Whether a steel counts as non-alloy or alloy follows the composition limits in the HS Chapter 72 notes, so check the chemical composition on the mill test certificate. Oil and gas line pipe, casing, tubing and drill pipe have their own subheadings.
