Import Tips
• Include FDA prior notice and shellfish tags documenting harvest waters to meet U.S. sanitation standards
• Label clearly as 'chilled clams' to distinguish from frozen or dried, preventing duty reassessment
• Watch for misdeclaration as mussels, which fall under a separate heading 0307.31
