International (HS 2022) · Section XV
Iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), welded, of square or rectangular cross-section, n.e.c. in chapter 73
HS 730661 — Iron or steel (excluding cast iron); tubes, pipes and hollow profiles (not seamless), welded, of square or rectangular cross-section, n.e.c. in chapter 73 — sits in Chapter 73 (Articles of iron or steel). Pipes, fittings, structural steel, fasteners, fencing, and steel kitchenware. These goods trigger the EU Carbon Border Adjustment Mechanism in addition to standard MFN duty — EU importers pay both customs charges and a per-tonne carbon cost calculated from country-specific emission defaults (see the CBAM panel below for live values). Classification disputes are decided by the section + chapter legal notes shown below — these are legally binding interpretation rules, not advisory text. The duty table renders live rates from authoritative tariff sources (EU TARIC, HMRC XI, USITC HTS); cross-country rows compare treatment under five tariff schedules.

Default emissions intensities for CN 730661
Under Commission Implementing Regulation (EU) 2025/486, EU importers of iron and steel under CN 730661 that cannot provide verified actual emissions from their supplier must use these country-specific default values. Defaults carry a regulatory markup that grows each year — +10% in 2026, +20% in 2027, +30% from 2028 — to incentivise verification. Multiplied by the EU CBAM certificate price (currently €75.36/tCO₂e) and shipment tonnage, this is the carbon-cost line on every consignment.
