Bio Based Resin Sourcing and Industrial Composting Compliance
Industrial composting compliance requires verifying bio-carbon via ASTM D6866, disintegration via EN 13432, and total fluorine screening below 100 ppm.
HS Code 390770
Meaning
International trade classifications assigned under the Harmonized System for poly(lactic acid) organize the customs documentation and duty rates for renewable polyester resins. The category hs code 390770 applies specifically to polylactide in primary forms, including pellets, granules, and powders. It distinguishes this bio-based polymer from traditional petroleum-based polyesters like polyethylene terephthalate.
This code governs the cross-border movement of polylactic acid.
Tariff Classification
Customs authorities use this specific entry to monitor the volume and origin of imported bioplastics. Under the global tariff system, hs code 390770 ensures that polylactic acid is not misclassified under broader polyester categories that carry different import duties. Accurate documentation prevents delays at international ports.
It provides the basis for statistical tracking of global bio-polyester trade.
Regulatory Compliance
Moulders and compounders must declare this classification on all commercial invoices and shipping manifests. Using the wrong tariff code can trigger customs audits and financial penalties for the importer of record. Compliance with hs code 390770 requirements is verified by chemical testing or material datasheets that confirm the polylactide chemistry of the resin.
Procurement teams rely on these documents to maintain clear customs declarations across regional warehouses.
Sourcing Cost
Import duties for this material vary by jurisdiction. Correct application of hs code 390770 allows polymer buyers to claim preferential tariff rates. The feasibility of replacing fossil-based resins relies directly on these duty calculations.
