Classification of stainless welded casing - CN 730621

CN code 730621 covers stainless steel welded casing and tubing pipes up to 406.4 mm diameter for oil and gas wells. Stainless casing is used in wells with elevated corrosion risk from CO2 or H2S environments. Produced from martensitic stainless (13Cr, Super 13Cr) or duplex (22Cr, 25Cr) by laser or TIG welding. API 5CT specifies requirements. Classification requires welding, stainless steel and casing/tubing purpose. Stainless casing represents the highest unit-value segment of oilfield tubular products.

Import requirements for stainless casing CN 730621

Importing under CN 730621 into the EU is subject to Union Customs Code and oil industry requirements. Pipes must comply with API 5CT or ISO 11960. Required documents include commercial invoice, material certificate with corrosion test results, weld and NDT inspection reports, transport documents and certificate of origin. From 1 January 2026, imports may be subject to CBAM. Pipes for corrosive environments must meet ISO 15156.
