Oysters, Prepared or Preserved

Smoked oysters are specifically classified at 1605514000, while all other prepared or preserved oysters (including those in brine, oil, or sauce) fall under 1605515000. Products that contain fish meat or are sold as prepared meals are classified under 1605510500. The smoking process is therefore a primary classification determinant.

China is the leading supplier by a wide margin, followed by South Korea and Japan. Vietnam and Spain are also notable sources. The Pacific Rim's dominance reflects large-scale oyster aquaculture and established canning and smoking operations in those countries.

FDA regulates prepared oysters under the Seafood HACCP program. Hermetically sealed, thermally processed oyster products may additionally fall under FDA's Low Acid Canned Food (LACF) regulations, requiring foreign processor registration of their thermal processes. Admissibility and classification are complex — consult a licensed customs broker or FDA before importing.
