US declares emergency, suspends AD/CVD duties on Moroccan phosphate fertilizer imports

Mechanism

Section 318(a) of the Tariff Act of 1930 (19 U.S.C. 1318(a)) grants the President emergency authority to suspend, in whole or in part, any provision of the customs/tariff laws when domestic supply of an essential commodity is threatened. Invoking that authority on 29 June 2026, the President declared an emergency over fertilizer availability and instructed Treasury, Commerce and (in consultation) DHS to suspend collection of duties — and deposits of estimated duties — under 19 U.S.C. §§1671 (CVD), 1675 (administrative/sunset reviews) and 1677j (downstream product AD/CVD provisions) specifically on phosphate fertilizer imports from Morocco. The suspension runs for the earlier of eight months from the proclamation or the emergency's termination.

This layers on top of an already-shrinking AD/CVD wall: a December 2025 US Court of International Trade remand cut the CVD rate applied to Morocco's OCP Group to 2.11%, down from the original higher rate set in the 2020-21 CVD investigation. The emergency duty suspension goes further, zeroing out even that reduced rate (plus any AD exposure) for the suspension window, reopening duty-free flow of Moroccan phosphate fertilizer into the US market during the northern-hemisphere planting season.

Why now

The proclamation's stated rationale — "threats to the availability of sufficient supplies of fertilizers to meet expected agricultural demand" — lands squarely in the aftermath of China's NDRC-coordinated phosphate export suspension (in force since December 2025, running to August 2026), which removed roughly 40% of global phosphate-fertilizer export supply from the market and pushed Q1 2025 Chinese export volumes to ~111,000 t versus a three-year average of 785,000 t. With China's supply effectively off the table through the 2026 planting season, Morocco — holding ~70% of world phosphate-rock reserves and already the top phosphate exporter — is the only source with the scale to backfill US demand. This action is best read as the US demand-side counterpart to that China supply shock: rather than building new domestic capacity, Washington is clearing the tariff wall on its largest viable external supplier for the duration of the shortage.

Downstream implications

• OCP Group (Morocco, state-owned) gains duty-free access to the US market

for up to eight months, a material volume and margin opportunity given the US is a large import-dependent buyer of DAP/MAP.

• US domestic producers (Mosaic, Nutrien) face increased import competition

during the suspension window, a reversal of the protective effect the AD/CVD order previously provided them.

• Reinforces Morocco's position as the residual swing supplier now that

China's phosphate exports are suspended — OCP is simultaneously the primary beneficiary of the CN NDRC action (2025-12-12) and of this US duty relief.

• Distinct from the separate Morocco Mining Code Article 72.24 item tracked

in ops/queue/upcoming.md (a different Moroccan-issued instrument) and from any standalone AD/CVD administrative case action.

Open questions

• Whether Treasury/Commerce implementing regulations narrow the suspension

to specific tariff lines or apply it across all phosphate fertilizer HS codes from Morocco.

• Whether the "termination of the emergency" trigger is exercised before

the eight-month backstop (i.e., once China's suspension lifts in August 2026 and global supply normalises).

• Whether this sets a precedent for Section 318(a) emergency authority being

used more broadly against future AD/CVD orders on critical agricultural or industrial inputs.
