Import Tips & Compliance
• Verify purity exceeds 90% active sulfonate content to avoid reclassification as mixtures under Chapter 38
• Provide chemical analysis certificates confirming only sulfo groups present, no halogens or nitro groups
• Ensure proper SDS and CAS# 25155-30-0 documentation for customs chemical classification
