Import Tips
• Provide detailed chemical analysis certificates confirming purity and acyclic diol structure to avoid reclassification as mixtures
• Ensure SDS and CAS number (504-63-2) documentation matches HTS description for acyclic alcohols
• Verify stabilizer additions comply with chapter note (f) to prevent exclusion from Chapter 29
