Import Tips & Compliance
• Ensure the product is a mixture of octyl derivatives of diphenylamine and not a single chemically defined compound, as this affects classification
• Keep a technical data sheet showing the composition to present to the CBSA if requested
• Verify whether the goods qualify for duty relief under a free trade agreement, as the MFN rate may not apply
