Classification of welded stainless tubes - CN 730640
CN code 730640 covers other welded stainless steel tubes up to 406.4 mm diameter, not under line pipe or casing subheadings. These are ERW or TIG welded stainless tubes for general industry: chemical, food, pharmaceutical, decorative and structural. Produced from austenitic AISI 304, 316L, 321 or ferritic 430 per EN 10217-7 or EN 10296-2. Diameters 10 mm to 406 mm. Welded stainless tubes are a cost-effective alternative to seamless where welding does not reduce functionality.
Import requirements and PED for stainless tubes CN 730640
Importing under CN 730640 follows Union Customs Code. Pressure tubes under PED 2014/68/EU with CE marking. EN 10217-7 specifies requirements. Documents: commercial invoice, material certificate EN 10204, weld and corrosion test reports, transport documents, certificate of origin. Food-contact pipes must comply with Regulation (EC) No 1935/2004. From 1 January 2026, CBAM may apply.

Welded stainless tubes are a significant market segment. Major suppliers: China, India, Taiwan, Korea, EU. Total costs: MFN, AD, safeguard, CBAM, VAT. TARIC for current rates.
Customs classification of other welded stainless tubes ≤406 mm (CN 7306 40)
CN code 7306 40 of the Combined Nomenclature covers other welded stainless tubes ≤406 mm within Chapter 73, which deals with articles of iron or steel. Classification in this chapter is based on the type of article, its intended use, manufacturing method (casting, forging, welding, stamping) and base material (cast iron, non-alloy steel, stainless steel or alloy steel). Correct classification requires analysis of technical documentation. Where classification is uncertain, importers can obtain Binding Tariff Information (BTI) ruling from customs authorities, valid for three years throughout.
Frequently asked questions
How do welded stainless (730640) differ from seamless (730441)?
Welded tubes are produced by forming strip and welding, seamless from solid material. Welded tubes are cheaper but have a weld seam as potential weak point. Seamless preferred for pressure and critical applications. Welded tubes sufficient for many decorative and structural uses.
Do AD duties apply to welded stainless from China?
EU AD duties on welded stainless tubes from China and India are established. AD rates vary by producer. Current scope and rates should be verified in TARIC as measures are periodically reviewed.
Are welded stainless tubes subject to CBAM?
From 1 January 2026, CBAM enters full operation. Welded stainless tubes under Chapter 73 may be subject to CBAM. Verify scope for 730640 and comply if covered.
How to obtain a BTI ruling for other welded stainless tubes ≤406 mm (CN 7306 40)?
