Yes. Frozen fish products from China, including tilapia and catfish under this heading, have been subject to Section 301 tariffs. Importers should verify the current tariff treatment in ACE and confirm the correct origin, as the additional duty applies on top of the base MFN rate and can significantly affect landed cost.

Line 0304930000 covers these species frozen in forms not elsewhere specified (typically whole or dressed). Line 0304931010 applies to minced product (excluding surimi) in bulk or containers over 6.8 kg. Line 0304931090 covers non-minced meat of these species in bulk or containers over 6.8 kg. The key classification variables are whether the product is minced and whether the container weight threshold is met.

Frozen catfish from Vietnam — and catfish-like species — may also fall under USDA FSIS jurisdiction depending on species classification under the 2008 Farm Bill catfish inspection provisions. Importers should confirm whether the specific species triggers FSIS mandatory inspection or remains under FDA HACCP oversight, as the two regimes have different facility approval and reinspection requirements.
