HS Code for Seamless steel tubing

Seamless steel tubing classified under HS code 7304.29 is categorized based on its specific end-use in the extraction of natural resources. This subheading covers casing and tubing of a kind used in drilling for oil or gas, provided they are made of iron or steel (excluding stainless steel and cast iron) and are manufactured using a seamless process. Classification follows GRI 1 and the specific nomenclature of heading 7304. These products are often referred to as Oil Country Tubular Goods (OCTG). The seamless nature is critical for withstanding the extreme subterranean pressures and corrosive environments found in oil and gas wells. Unlike general-purpose pipes, these tubes must meet rigorous standards, such as those set by the American Petroleum Institute (API), regarding tensile strength and collapse resistance. Subheading 7304.29 acts as a residual category for casing and tubing that does not meet the definitions of other specific subheadings within the 7304.2x group, such as those made of specific alloy steels or those with different finishing characteristics.

Products Included

• Seamless oil well casing
• Seamless production tubing for gas wells
• OCTG tubing (non-stainless)
• Seamless drill pipe (if not classified elsewhere)
• External upset tubing for oil extraction

Common Misclassification

A common error is classifying these products under 7304.11 or 7304.19, which are reserved for line pipe used for oil or gas pipelines. Line pipe is used for transporting fluids over distances, whereas 7304.29 is for the actual drilling and extraction process within the wellbore. Another misclassification occurs with 7304.39, which is for general-purpose non-alloy seamless tubes. If the tubing is intended for oil/gas drilling, the specific use-based code 7304.29 takes precedence over the general-purpose code. Furthermore, if the tubing is made of stainless steel, it must be classified under 7304.22 or 7304.24.

FAQ

What is the HS code for oil well casing?

Seamless casing used in oil or gas drilling is classified under HS code 7304.29, provided it is not stainless steel.

Is line pipe classified under HS code 7304.29?

No, line pipe used for the transport of oil or gas is classified under heading 7304.11 or 7304.19, depending on the material.
