Refined Shark Liver Oil from China
Shark liver oil, particularly from species like deepwater sharks, is refined to concentrate squalene and omega-3s for cosmetic and supplement use. Falls under HTS 1504.10.40.00 as 'other' fish-liver oils, provided no chemical modification occurs. Squalene content distinguishes it but doesn't change base classification.

Import Tips
• Document shark species and liver extraction method; CITES permits may apply for certain endangered sharks
• Confirm refinement process via processing records to differentiate from crude oils or modified versions
• Test for squalene purity if marketed as such, as impurities could trigger reclassification or FDA rejection
