Import Tips
• Ensure documentation specifies liver origin and refinement only (no chemical alteration) to stay in 1504.10; test for peroxide values
• Comply with US FDA seafood import rules, including Hazard Analysis and Critical Control Points (HACCP) plans for fish oils
• Avoid common pitfalls like mislabeling as 'fish oil' generically, which could lead to scrutiny over liver-specific classification
