HS Code for Oil and gas pipe

Oil and gas pipes are classified under HS code 7304.19 when they are seamless and made of iron (other than cast iron) or non-stainless steel. Chapter 73 covers articles of iron or steel, and heading 7304 is reserved for tubes, pipes, and hollow profiles that are seamless. Subheading 7304.19 specifically covers "line pipe of a kind used for oil or gas pipelines" made of steel other than stainless steel. The classification is determined by the manufacturing method (seamless), the material composition (carbon steel or alloy steel, but not stainless), and the specific intended application (line pipe for transporting hydrocarbons). These pipes must meet specific industrial standards, such as API 5L, to be categorized as line pipe under this heading. The seamless nature of these pipes is critical for high-pressure applications in the energy sector, distinguishing them from welded alternatives which are classified elsewhere based on their diameter and welding method.

Products Included

Common Misclassification

Oil and gas pipes are frequently misclassified under HS code 7304.11, which is specifically for stainless steel seamless pipes. Another common error is using HS code 7305 or 7306; these codes are for welded pipes. Specifically, 7305 covers welded pipes with an external diameter exceeding 406.4 mm, while 7306 covers other welded pipes. If the pipe has a longitudinal or spiral seam, it cannot be classified under 7304.

FAQ

What is the HS code for oil and gas pipe?

The HS code for seamless line pipe of iron or non-stainless steel used for oil and gas pipelines is 7304.19.

Does this code include welded pipes?

No, welded pipes are classified under HS code 7305 (for large diameters) or 7306 (for smaller diameters), depending on their specific dimensions and construction.
