Import Tips
• Verify that the ammonia content is within the 'very small amounts' allowed for stabilizers per chapter note 5(B)(iii) to avoid reclassification
• Provide a safety data sheet (SDS) for the latex, as it is a liquid with ammonia
• Confirm the latex is not prevulcanized unless it retains raw rubber character
