About HS Code 730629

This HS code covers casing and tubing made of iron or steel (excluding cast iron), specifically used in drilling for oil and gas, but importantly, these are *not* seamless and *not* of stainless steel. These products are typically welded pipes, offering a cost-effective alternative to seamless pipes for certain applications within the oil and gas industry, particularly where extreme pressures or highly corrosive environments are less critical. Importers include oilfield service companies, pipeline construction firms, and energy project developers. Exporters are large steel pipe manufacturers. Trade volumes are influenced by global energy demand, the scale of new oil and gas exploration projects, and the ongoing maintenance of existing energy infrastructure.

Products Under This Code

Welded oil well casing, welded production tubing, welded line pipe for oil/gas, structural pipe for offshore platforms, API 5L welded pipe, ERW (Electric Resistance Welded) casing, spiral welded pipes

Real World Examples

EVRAZ welded OCTG, Tenaris welded casing, JFE welded line pipe, TMK welded production tubing, Welspun welded pipes

Common Misclassification

Often confused with 730429 (seamless OCTG) or 730621 (stainless steel OCTG), as the 'non-seamless' (welded) and 'non-stainless' characteristics are the key differentiators for this code.

EU Regulatory Requirements

This product falls under the Carbon Border Adjustment Mechanism (CBAM). Importers to the EU must declare embedded carbon emissions and purchase CBAM certificates.
