Meaning
Mandatory border verification executed by the General Administration of Customs of China evaluates imported plastic resins and recycled plastic pellets against national environmental and quality standards. Covering customs entry points across China, a GACC import inspection verifies material declarations and chemical compliance under standards such as GB/T 40006 for recycled plastics. Customs officials sample shipments to identify unwashed post-consumer waste or misdeclared polymer grades.
The inspection boundary ends upon customs release or official rejection at the port of entry.
Border Sampling
Physical sampling of imported bulk container loads takes place at port customs control zones. Applying a GACC import inspection involves selecting container units for visual inspection and moisture verification. Inconsistent pellet coloration or non-polymeric debris triggers immediate laboratory analysis.
Sampling delays accumulate port storage charges while waiting for chemical verification reports.
Purity Verification
Laboratory testing of sampled polymer lots determines compliance with impurity thresholds established by national standards. A standard GACC import inspection measures ash content, volatile organic compounds, heavy metal residues and foreign polymer inclusions. Contamination levels exceeding national thresholds result in mandatory return of cargo to the port of origin.
Rejection orders cannot be appealed through secondary processing or local sorting within Chinese territory.
Declaration Matching
Documentation submitted through customs portals must match the physical characteristics of the imported polymer load. Discrepancies identified during a GACC import inspection lead to cargo seizure and administrative fines.
