Import Tips & Compliance
• Verify that the isinglass is not treated with enzymes, as enzymatic preparations fall in Chapter 35 but under different headings
• Declare the fish species (e.g
• sturgeon) to the CBSA, as some species may be regulated under CITES
• Keep import permits for any controlled species ready for inspection
