Ammonium dihydrogenorthophosphate (Monoammonium phosphate) and mixtures thereof with diammonium hydrogenorthophosphate (Diammonium phosphate)
HS 31054000 — Ammonium dihydrogenorthophosphate (Monoammonium phosphate) and mixtures thereof with diammonium hydrogenorthophosphate (Diammonium phosphate) — sits in Chapter 31 (Fertilisers). Nitrogen, phosphate, potassium fertilisers; compound fertilisers. 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 31054000
Under Commission Implementing Regulation (EU) 2025/486, EU importers of fertilisers under CN 31054000 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 0.290 tCO₂e/t (cleanest: New Zealand) to 0.670 tCO₂e/t (highest: China) across CBAM-eligible origins — a 2.3× spread that makes origin choice a real cost lever.

| Morocco | 49.0% | 0.370 | 0.374 | 0.374 | 0.374 |

US initiates full five-year review of phosphate fertilizer CVD orders
The U.S. International Trade Commission announced on 17 June 2026 that it will conduct full five-year reviews of existing countervailing duty (CVD) orders on phosphate fertilizers from Morocco and Russia. Under the Tariff Act of 1930, the Commission must determine whether revoking these orders would likely cause a recurrence of material injury to the domestic industry. The outcome will determine whether the CVD orders remain in force or are revoked. A detailed schedule for the reviews will be published later.
