Import Tips & Compliance
• Declare exact stabilizer identity and concentration (<0.5% typically) per Chapter Note (f) limits
• Stabilizer must be GRAS-listed for food contact applications to maintain chemical classification
• Avoid hydroquinone or BHT levels exceeding 0.1% which trigger specific use determination
