Import Tips
• Declare exact alkyl chain length; n-propyl vs iso-propyl determines subheading precision
• Pharma-grade requires USP/EP certificates; technical grade may face lower duties but stricter safety rules
• Monitor REACH compliance for EU transshipment; affects US import documentation requirements
