Verifying Inorganic Filler Concentrations in Foreign Masterbatches Crossing Trade Borders
Verify masterbatch ash content via ISO 3451 calcination at 600°C to protect duty lines, catch mineral substitution, and prevent process failures.
HS Code 3901.20
Meaning
Commodity trade classification designates high density polyethylene polymers possessing a specific gravity of zero point nine four or higher. Raw resin declared under hs code 3901.20 includes blow moulding grades, extrusion pipe resins and injection moulding materials. The code applies to virgin virgin pellets, uncompounded powders and natural virgin granules, stopping where low density polyethylene or modified ethylene copolymers are imported.
Density Boundary
Physical property thresholds require exact density verification to distinguish high density grades from linear low density polyethylenes. Entry under hs code 3901.20 relies on standard displacement density testing of unpigmented polymer samples. Misclassifying resin density leads to incorrect tariff applications and customs compliance audits.
Resin Classification
Primary polymer forms imported for plastic conversion undergo mandatory tariff categorization based on monomer content. Assigning hs code 3901.20 confirms the material consists of ethylene homopolymer or ethylene alpha-olefin copolymer with high density metrics. Proper resin classification facilitates international trade accounting and raw material tracking.
Sourcing Economics
High density polyethylene sourcing relies on clear commodity code declarations to negotiate international freight rates. Utilizing hs code 3901.20 aligns bulk resin purchasing with regional trade agreements and duty drawback programs. Accurate trade reporting supports cost forecasting for large scale injection and blow moulding operations.
