International (HS 2022) · Section XV
Tubes, pipes and hollow profiles, of cast iron
HS 7303 — Tubes, pipes and hollow profiles, of cast iron — 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.

EU CBAM emissions defaults
Default emissions intensities for CN 7303
Under Commission Implementing Regulation (EU) 2025/486, EU importers of iron and steel under CN 7303 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.
Intensity ranges from 1.350 tCO₂e/t (cleanest: Myanmar) to 7.890 tCO₂e/t (highest: Indonesia) across CBAM-eligible origins — a 5.8× spread that makes origin choice a real cost lever.
| Origin | Share of EU imports | Default tCO₂e/t | 2026 (+10%) | 2027 (+20%) | 2028+ (+30%) |
|---|---|---|---|---|---|
| India | 47.7% | 2.840 | 3.124 | 3.408 | 3.692 |
| China | 38.0% | 2.191 | 2.410 | 2.629 | 2.848 |
| Turkey | 8.5% | 2.480 | 2.728 | 2.976 | 3.224 |
| Iran | 3.4% | 1.860 | 2.046 | 2.232 | 2.418 |
| United Arab Emirates | 2.4% | — | — | — | — |
