The US Marine Mammal Protection Act (MMPA) will officially take effect on January 1, 2026, bringing one of the most significant seafood import bans in history. The new regulation will restrict $3.6 billion worth of seafood products that fail to meet US standards for marine mammal protection and sustainable fishing practices.
With the United States importing around $25.8 billion in seafood annually, the impact of the MMPA will be felt across global seafood trade, from Asia to South America.
What Is the US Marine Mammal Protection Act (MMPA)?
The MMPA is designed to prevent seafood imports from fisheries that harm marine mammals through bycatch or unsustainable fishing practices. To enter the US market, seafood products must now carry joint certification from both the exporting country’s competent authority and the US importer, confirming compliance with NOAA’s rules.
According to NOAA Fisheries, US Customs and Border Protection will work together to enforce the ban, ensuring that restricted products do not enter the country.
Which Seafood Products Are Restricted?
The US National Marine Fisheries Service (NMFS) has identified 178 seafood products for priority regulation. These include:
- Wild-caught prawns, cobia, flatfish, grouper
- Multiple species of tuna and squid
- Swimming crab, lobster, snapper, cuttlefish
- Anchovies, herring, hairtail, yellow croaker
- Swordfish, mackerel, pomfret, shad
Even semi-finished products are affected — for example, Russian haddock processed in China and re-exported will no longer be eligible for the US market.
Countries Most Affected by the US seafood import ban 2026
The regulation will reshape seafood supply chains worldwide. Some of the hardest-hit exporters include:
- Vietnam: 12 restricted products, including tuna, squid, grouper, lobster, and swimming crab.
- Chile: Trawled mackerel and hake.
- Indonesia: Swimming crab placed on watchlist due to trawl gear.
- Ecuador: Multiple species of tuna, swordfish, and mackerel.
- China: Anchovies, croaker, squid, pomfret, herring, and crab from the East China Sea, South China Sea, and Bohai Sea.
- Russia: Semi-finished haddock processed in third countries banned.
Other affected nations include Mexico, South Korea, the Philippines, Colombia, Turkey, Venezuela, Senegal, Myanmar, Malaysia, Bangladesh, Saudi Arabia, Ireland, UAE, Nigeria, Oman, Namibia, Ghana, and Togo.
By contrast, Canada and India — two of the US’s largest seafood suppliers — remain unaffected since their products already comply with MMPA standards.
Industry Reactions and Global Concerns
The MMPA has sparked strong pushback from exporting nations:
- The Vietnam Association of Seafood Exporters and Producers (VASEP) warned that the ban threatens the livelihoods of hundreds of thousands of fishermen, disrupts supply chains, and harms Vietnam’s international reputation in sustainability.
- The Vietnamese government has formally appealed to the US Department of Commerce, urging a review of NOAA’s decision.
- Other industry stakeholders argue the regulations could unfairly penalize compliant fisheries that are caught up in blanket restrictions.
What’s Next for Exporters?
Countries on the restricted list may reapply for compliance after January 1, 2026, but only if they can prove alignment with US marine mammal protection standards.
For now, exporters face two urgent challenges:
- Adapting supply chains to avoid restricted products.
- Securing NOAA certification to continue accessing the lucrative US seafood market.
Key Takeaways
- Effective Date: January 1, 2026
- Impact: $3.6 billion in restricted seafood products
- Major Suppliers Affected: Vietnam, Chile, Indonesia, Ecuador, China, Russia
- Exempt Countries: Canada and India
- Global Effect: Reshaping seafood trade flows and compliance requirements
The US seafood import ban under the Marine Mammal Protection Act is more than just a regulatory shift — it’s a global trade disruptor that will redefine how seafood is harvested, certified, and exported. For exporters, compliance is no longer optional; it is the only way to maintain access to the world’s largest seafood consumer market.
