HS Code for Steel tubing

Steel tubing used specifically for oil and gas drilling is classified under HS code 7306.29. This code applies to other tubes and pipes (typically welded or otherwise joined) that are not made of stainless steel and are not seamless. The classification is functional, targeting the casing and tubing used in the extraction of hydrocarbons. Heading 7306 covers tubes, pipes, and hollow profiles with a circular cross-section and an external diameter not exceeding 406.4 mm, or those with non-circular cross-sections. The distinction between 7306.29 and other subheadings is based on the intended use in the petroleum industry and the specific manufacturing method. Because these are not seamless, they are excluded from heading 7304. Furthermore, because they are not made of stainless steel, they are excluded from 7306.11 and 7306.21. This classification ensures that specialized industrial piping for the energy sector is tracked separately from general-purpose plumbing or structural tubing.

Products Included

• Welded carbon steel oil well casing
• Electric resistance welded (ERW) tubing for gas wells
• Non-seamless drill pipe sections
• Threaded steel casing for oil extraction
• Welded steel liners for boreholes

Common Misclassification

The most frequent misclassification occurs with HS code 7304.29, which is for seamless casing and tubing. Importers often confuse welded and seamless varieties. Another common error is using 7305.20, which is reserved for casing and tubing with an external diameter exceeding 406.4 mm. If the tubing is made of stainless steel, it must be classified under 7306.21. General purpose welded pipes not intended for oil/gas wells should be classified under 7306.30 or 7306.61.
