Import Tips & Compliance
• Bulk blocks need weight-out certificates accurate to 0.1%; discrepancies lead to valuation disputes
• Refrigerated container specs mandatory (reefer set to -25°C); heat damage voids claims
• Screen for block-processed fillets disguised as whole, shifting to higher-duty 0304
