Classification of cold-drawn alloy seamless tubes - CN 730451
CN code 730451 of the Combined Nomenclature covers seamless tubes of alloy steel (other than stainless), cold-drawn or cold-rolled, of circular cross-section. Alloy steel under the CN means steel containing specified alloying additions (molybdenum, chromium below 10.5%, vanadium, nickel and others) conferring special strength or heat resistance properties. These tubes are manufactured from hot-rolled base tubes through cold drawing, providing tight dimensional tolerances and improved mechanical properties. Applications include power generation (boiler tubes, superheater tubes), petrochemical, automotive and aerospace industries. Commonly produced from grades 13CrMo4-5, 10CrMo9-10, 16Mo3, 25CrMo4, 34CrMo4 and 42CrMo4 per EN 10216-2 or EN 10305. Classification requires three criteria: seamless, alloy steel (not stainless) and cold working.
Import requirements and PED for alloy tubes CN 730451
Importing cold-drawn alloy seamless tubes under CN code 730451 into the EU is subject to Union Customs Code provisions and stringent technical requirements. Alloy pressure tubes fall under PED 2014/68/EU requiring CE marking, declaration of conformity and conformity assessment. EN 10216-2 specifies requirements for pressure tubes from non-alloy and alloy steel for elevated temperature service. Required documents include commercial invoice with technical specification, material certificate EN 10204 type 3.1 or 3.2, NDT reports (UT, ET), transport documents and certificate of origin. From 1 January 2026, imports may be subject to CBAM. Alloy tubes for power plant applications often face additional qualification requirements from plant operators and technical inspection authorities.
Trade measures for alloy seamless tubes CN 730451
Cold-drawn alloy seamless tubes under CN code 730451 are subject to EU safeguard measures in TRQ form with an additional 25% duty. Anti-dumping duties on seamless steel pipes from China may cover alloy tubes. Imports from Russia and Belarus are subject to EU sanctions prohibitions. AD duties may apply to tubes from India and Turkey. Preferential rates are available under free trade agreements. Cold-drawn alloy tubes represent a specialist high-value-added segment used in power generation and chemical industries. Major suppliers include producers from Japan, Korea, China, India 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 cold-drawn alloy seamless tubes (CN 7304 51)
CN code 7304 51 of the Combined Nomenclature covers cold-drawn 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.
Frequently asked questions
What alloy steel grades are used in tubes under CN 730451?
Most common are heat-resistant grades: 13CrMo4-5, 10CrMo9-10 and 16Mo3 for service temperatures up to 580 degrees Celsius. Quenched and tempered grades 25CrMo4, 34CrMo4 and 42CrMo4 are used in machine components and automotive. Grade selection depends on operating temperature, pressure and required mechanical properties. Material certificate confirms grade and properties.
Do cold-drawn alloy tubes require CE marking?
Alloy pressure tubes are subject to PED 2014/68/EU and require CE marking, EU declaration of conformity and technical documentation. Higher pressure categories require notified body involvement. Boiler and superheater tubes face particularly stringent requirements. Material certificate EN 10204 type 3.1 or 3.2 is mandatory.
Are alloy tubes (CN 730451) subject to CBAM from 2026?
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 CBAM scope for subheading 730451. Where applicable, registration and embedded emissions reporting are required.
What is the EU duty rate for CN code 7304 51 in 2026?
The duty rate for CN code 7304 51 (cold-drawn 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.
