The U.S. extends the exemption period of the 301 investigation, providing a temporary 90-day safety period for blackline cod and flounder species.
This extension of the exemption covers 178 items, including 10 seafood products worth $105 million (2024 trade value), such as black cod fillets and halibut fillets.
In 2024, the U.S. imported 22,742 tons of frozen black cod and halibut fillets from China, with 11,963 tons imported in the first half of 2025. Most of the raw materials for black cod and halibut are sourced from Norway or Alaska, processed in China, and then re-exported to the U.S., completing a significant closed-loop supply chain through Chinese processing plants.
Section 301 of the U.S. Trade Act of 1974 authorizes Washington to investigate and respond to unfair trade practices by foreign countries, including imposing tariffs and other restrictive measures. In 2018, then-U.S. President Trump initiated an investigation into China for stealing intellectual property from U.S. companies.
In July and August 2018, Trump imposed tariffs on $34 billion and $16 billion worth of imported goods, respectively. In September of the same year, Trump imposed tariffs on approximately $200 billion worth of imported goods, expanding the scope to include seafood such as tilapia, squid, shrimp, tuna, and crab. President Biden maintained these tariffs during his term without any adjustments.
As of 2024, U.S. importers have cumulatively paid over $1.1 billion in Section 301 tariffs, placing a heavy burden on the entire industry, and causing significant price increases for some U.S. seafood products. However, these tariffs have not prompted any changes from China in recent years. The new tariff exemption extension will provide a temporary reprieve for the black cod and halibut supply chain, but policy remains uncertain after November.
