Import Tips
• IQF requires proof of individual freezing process in entry docs to distinguish from block-frozen under same code
• Test for histamine levels mandatory for scombroid species relatives; herrings prone to issues
• Avoid partial thawing in shipping; CBP may reject if not demonstrably frozen whole fish
