The Harmonized System (HS) is the global standard for classifying traded goods. For chemicals, getting the HS code right is the difference between smooth clearance and costly delays.
Why HS Codes Matter
Your HS code determines the applicable duty rate, the documentation required, and whether the shipment triggers additional regulatory checks. A wrong code can mean penalties, seizures or re-classification at the border.
How Chemicals Are Classified
Most chemicals fall under Chapters 28 (inorganic) and 29 (organic) of the HS, with further subdivisions by compound family. Pharmaceutical ingredients often sit in Chapter 30, while specialty preparations may fall elsewhere depending on composition and use.
Getting It Right
Work from the exact chemical identity — name, CAS number and purity — rather than the commercial description. A reliable supplier provides the correct HS code alongside the Certificate of Analysis so your paperwork is consistent end to end.
