Last updated: July 2026 dataNew Zealand green-lipped mussels (Perna canaliculus) and Chilean blue mussels (Mytilus chilensis) together account for the bulk of frozen mussel imports into the US, with New Zealand leading overall volume. The single US tariff line (0307320000) covers both Mytilus spp. and Perna spp. frozen product, meaning species must be declared in commercial documentation even though classification does not change. Frozen mussels are subject to FDA seafood HACCP regulations, and product from China — a growing supplier — may be subject to Section 301 tariffs. The frozen format supports longer shelf life and broader distribution into retail and foodservice channels compared to live product, making this a high-volume segment of the shellfish import market.

Both are classified under 0307320000, so species must be specified in purchase contracts and labeling.
