Import Tips

• Provide CoA confirming aromatic substitution on lactone ring to distinguish from aliphatic GBL (2932.20.5010)

• Include end-use statement specifying industrial solvent/pharma intermediate to avoid DEA scrutiny

• Package in industrial drums, not consumer sizes, to maintain chemical compound classification
