Import Tips
• Ensure accurate weight declaration including shells, as duties apply to gross weight for in-shell molluscs
• Comply with Lacey Act by providing species declaration to trace origin and prevent illegal fishing penalties
• Avoid common pitfall of declaring as 'mixed seafood' which could trigger higher scrutiny or reclassification
