Import Tips
• Confirm via NMR/CoA that sulfur is NOT directly carbon-linked as sulfonated derivative to avoid 2930 misclassification
• Ship with anticaking stabilizer only if necessary for transport (note f); excess additives trigger specific-use exclusion
• Declare CAS 121-47-1 precisely; customs often challenges sulfonic acids against organo-sulfur headings
