Import Tips

• Provide chemical structure diagrams and CAS number (if available) in import docs to match the precise nomenclature in 2922.19.2000

• Declare as lab or industrial chemical with stabilizer if added for transport, per Chapter 29 note (f), to avoid reclassification

• Watch for pharma-specific FDA regs; improper end-use claims could trigger scrutiny under medicinal headings like 3002
