Import Tips

Provide structural formula verification; customs may test for sulfur-carbon linkage per Chapter 29 organo-sulfur definition

Declare CAS number (14484-64-1) accurately to prevent confusion with iron salts

Avoid packaging over 25kg drums if claiming pure compound status to dodge bulk chemical prep classification
