Mass Balance Verification Protocols for Recycled Polyolefin Customs Audit Compliance
Verify polyolefin mass balance imports by auditing site-level yield losses, enforcing ISO 22095 credit retirements, and anchoring claims to batch records.
Rule of Origin Verification
Meaning
Trade protocols confirm where the essential transformation of a resin occurred for customs purposes. A rule of origin verification determines if a product qualifies for preferential tariff treatment under a free trade agreement. Customs authorities look for evidence that the raw materials were significantly processed in a member country.
If the processing was minor, the goods may be treated as coming from a non-member state.
The Value
Local labour and materials must exceed a certain cost threshold.
A Shift
Change in the tariff classification code signals a substantial transformation. During a rule of origin verification, the importer must show that the input chemicals were converted into a new product with a different four digit tariff heading. This shift proves that real manufacturing took place rather than simple packaging or assembly.
Documenting this transition is the most common way to satisfy the requirements of international trade laws.
Companies Burden
Detailed records of sourcing and production costs must be maintained. A rule of origin verification can be triggered years after the goods have crossed the border. If the manufacturer cannot provide the necessary cost breakdowns and supplier declarations, the importer may be forced to pay the full duty rate.
This risk makes accurate and organized record keeping a necessary part of the global plastic trade.
