Import controls on plastic waste require authorised types, document certification, lab testing and environmental clearances before clearance. Policy restricts import of plastic waste/scrap to the capacity and specific types authorised in a unit's Letter of Approval, permitting only virgin/new fractions meeting a technical definition and PET bottle waste; each consignment must have a factory certificate and importer declaration, be sampled and laboratory-tested prior to clearance, and units must obtain pollution control consents and hazardous waste permissions as applicable.
