Packaging:
The bottles have APCHEM lables show-casing the name of the solvent, the grade it belongs to, the required specifications of the solvents, UN No., CAS No., Country of Origin as well as the necessary precautions to be taken at the time of usage or transit. These lables are printed as per the international standards. The bottles will be placed in a polystyrene box and packed in 5-ply corrugated box. All our cartons are UN approved and adequate for export by sea and road.
