Import Tips
• Clarify the degree of chemical modification, as heavily sulphated products may be classified as synthetic tanning agents
• Provide a technical data sheet to CBSA showing the sulphation process and the vegetable base
• Check if the product is considered a 'colouring matter' under Chapter 32 notes, which could affect classification
