Import Tips

Verify purity certificate and CAS number (75-07-0) matches HTS 2912.12.00.00 for acyclic aldehydes; impurities may shift classification

Include Material Safety Data Sheet (MSDS) showing stabilizer if present, as per Chapter 29 note (f), to avoid reclassification

Ensure UN-approved containers for flammable liquids (UN 2832) to prevent customs delays on hazardous goods declarations
