Import Tips
• Provide a certificate of analysis demonstrating the product meets the surface tension and emulsion stability criteria of Chapter 34 Note 3
• If the emulsifier is mixed with other additives for a specific end-use, consider whether it remains a surface-active agent or becomes a prepared additive
• Keep records of the chemical composition to distinguish from petroleum-based products of Chapter 27
