HS Code for Seamless steel line pipe

Seamless steel line pipe is classified under HS code 7304.19. This classification applies to tubes and pipes of a kind used for oil or gas pipelines, manufactured without a welded seam. Line pipes are designed to transport oil, gas, or water over long distances from the extraction site to refineries or storage facilities. Heading 7304 covers seamless products, and the 10-series subheadings (7304.11 and 7304.19) are specifically for line pipe. Subheading 7304.19 is used for pipes made of iron or steel other than stainless steel. These pipes are typically manufactured to API 5L specifications, which define the requirements for various grades of line pipe. The classification is based on the intended use (pipelines) and the manufacturing method (seamless), as well as the material composition (non-stainless steel).

Products Included

• API 5L seamless line pipe (Grades B, X42, X52, etc.)
• Seamless pipes for natural gas transmission
• Seamless oil transport pipelines
• Hot-finished seamless line pipe for energy infrastructure
• High-pressure seamless line pipe

Common Misclassification

Seamless line pipe is often misclassified under 7304.39 or 7304.59, which are general-purpose subheadings for "other" seamless pipes. However, if the pipe is specifically designed and rated for use in oil or gas pipelines (e.g., meeting API 5L standards), 7304.19 takes precedence due to its specific functional description. Another common error is confusing it with welded line pipe, which falls under 7305 (for large diameters) or 7306 (for smaller diameters). Additionally, line pipe made of stainless steel must be classified under 7304.11, not 7304.19. It is vital to distinguish line pipe from casing (7304.29), as line pipe is for transport while casing is for wellbore lining.

FAQ

What is the HS code for seamless steel line pipe?

The HS code for seamless steel line pipe (non-stainless) used for oil or gas pipelines is 7304.19.

Can 7304.19 be used for water pipes?

While 7304.19 is specifically described for oil and gas pipelines, pipes of the same specification used for high-pressure water transmission are often classified here if they meet the technical standards of line pipe. However, general-purpose water pipes are usually classified under 7304.39 or 7304.59.
