Classification of other alloy seamless tubes - CN 730459
CN code 730459 of the Combined Nomenclature covers other seamless tubes of alloy steel (other than stainless) not included under subheading 730451 (cold-drawn). These are hot-rolled or hot-finished alloy tubes of circular cross-section. Used in power generation, petrochemical, chemical and district heating where resistance to elevated temperatures and pressures is required. Produced from heat-resistant and quenched-and-tempered alloy steels per EN 10216-2 or ASTM A335. Classification under 730459 is residual, covering seamless alloy tubes not cold-worked. Diameters range from 21 mm to 610 mm, wall thicknesses from 2 mm to 100 mm.
Import requirements and regulations for alloy tubes CN 730459
Importing alloy seamless tubes under CN code 730459 into the EU is subject to the same requirements as subheading 730451. Pressure tubes fall under PED 2014/68/EU with CE marking and conformity assessment. EN 10216-2 specifies material and testing requirements. Required documents include commercial invoice with technical specification, material certificate EN 10204 type 3.1 or 3.2, NDT reports, transport documents and certificate of origin. From 1 January 2026, imports may be subject to CBAM. Power plant and heating plant tubes face additional technical inspection requirements.
Trade defence measures for alloy tubes CN 730459
Alloy seamless tubes under CN code 730459 are subject to EU safeguard measures in TRQ form with an additional 25% duty. Anti-dumping duties on seamless steel pipes from China may apply. Imports from Russia and Belarus are subject to EU sanctions prohibitions. Preferential rates are available under free trade agreements. Hot-finished alloy tubes are more price-accessible than cold-drawn but have wider tolerances. Major suppliers include producers from China, India, Japan and EU countries. Total import costs include MFN duty, AD duties, safeguard surcharge, CBAM charges and VAT. Current rates should be verified in TARIC.
Customs classification of other alloy seamless tubes (CN 7304 59)
CN code 7304 59 of the Combined Nomenclature covers other alloy seamless tubes 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 the EU.
Frequently asked questions
How do tubes under CN 730459 differ from cold-drawn (730451)?
Tubes under 730459 are hot-rolled or hot-finished without final cold working, resulting in wider dimensional tolerances. Tubes under 730451 undergo cold drawing with tighter tolerances. The final processing method confirmed in technical documentation is the distinguishing criterion. Hot-finished tubes are more price-accessible.
What standards govern hot-finished alloy seamless tubes?
Heat-resistant alloy pressure tubes are governed by EN 10216-2 specifying material, dimensional and testing requirements for service temperatures up to 580 degrees Celsius. The US equivalent is ASTM A335. Material certificate EN 10204 type 3.1 or 3.2 is mandatory. CE marking is required under PED 2014/68/EU.
Are hot-finished alloy tubes (CN 730459) subject to CBAM?
From 1 January 2026, CBAM enters its full operational phase. Alloy seamless tubes as steel products under Chapter 73 may be subject to CBAM under Annex I of Regulation (EU) 2023/956. Importers should verify the current scope for subheading 730459. Where applicable, registration and emissions reporting are required.
What is the EU duty rate for CN code 7304 59 in 2026?
The duty rate for CN code 7304 59 (other alloy seamless tubes) is set in the TARIC tariff and depends on the country of origin. Preferential rates may apply under EU trade agreements. The current rate can be checked in the European Commission's.
