HS Code for Oilfield tubing
Oilfield tubing under HS code 730629 includes welded casing and tubing used in oil and gas drilling that is not made of stainless steel and does not exceed the diameter limits of heading 7305. This code serves as a residual category for welded oil-country tubular goods (OCTG) that are not elsewhere specified. Tubing is the pipe through which oil or gas is produced from the wellbore to the surface. The classification depends on the welding method (such as Electric Resistance Welding or ERW) and the intended use in the petroleum industry. It is distinct from seamless tubing (7304) and large-diameter welded casing (7305). Importers must be careful to distinguish between tubing (used for production) and casing (used for structural lining), although they often fall under the same subheadings if the manufacturing method and material are identical. The 730629 code is specifically for items that are not stainless steel; stainless steel versions would fall under 730621. This classification requires the product to be of a kind used in drilling for oil or gas, which implies specific threading and pressure-bearing capabilities that standard structural pipes do not possess.
Products Included
- Electric resistance welded (ERW) production tubing
- Welded steel casing (diameter ≤ 406.4mm)
- Non-seamless oilfield production pipes
- Welded iron tubing for gas wells
- Carbon steel welded OCTG tubing
Common Misclassification
The most common misclassification is with 730429, which is for seamless tubing. Another common error is using 730630, which is for general-purpose welded pipes of circular cross-section. Because oilfield tubing is a specialized product, it must stay within the 73062x subseries.
