Meaning
A trade nomenclature code identifies polyethylene with a specific gravity of 0.94 or higher for customs and statistical purposes. The designation hs 3901.20 is reserved for high density polyethylene which is commonly used in blow moulding for bottles and extrusion for piping. It serves as the primary identifier for tracking the global movement of high density resins.
High Density
The molecular structure of the material consists of long, unbranched chains that pack closely together. Resins classified under hs 3901.20 exhibit greater stiffness and higher tensile strength than the lower density variants. This increased density is the defining characteristic that border authorities use to verify the declaration against the physical goods.
Molecular Weight
The physical properties of the plastic must meet the specific criteria of the harmonized system. While hs 3901.20 covers a wide range of melt flow indices, the density must remain above the 0.94 threshold. Laboratory certificates of analysis are provided with every shipment to prove that the resin meets these technical requirements.
Export Category
Global trade statistics rely on the accurate use of this code to monitor the supply and demand of industrial plastics. Declaring goods as hs 3901.20 ensures that the shipment is grouped with similar high performance resins rather than flexible packaging materials. This distinction is vital for companies that manufacture durable goods and need to ensure the correct application of trade quotas.
Proper classification under this code prevents the financial risk of duty reassessment during the import process.
