About HS Code 390311
This HS code specifically covers expansible polystyrene (EPS) in its raw, primary forms, typically as beads containing a blowing agent like pentane. It's a critical material for insulation and protective packaging due to its ability to expand significantly when heated, forming lightweight, shock-absorbing, and thermally insulating foam. Chemical manufacturers are the primary exporters, while construction companies, packaging manufacturers, and appliance makers are the main importers. Key considerations include the blowing agent's environmental impact and the shift towards more eco-friendly alternatives, fire retardancy requirements for building applications, and the increasing global demand for energy-efficient building materials and protective packaging solutions.
Products Under This Code
EPS beads, pre-expanded EPS beads, flame-retardant EPS, high-density EPS, low-density EPS, graphite-enhanced EPS, recycled content EPS beads
Real World Examples
BASF Styropor, Versalis Edistir, Sunpor EPS, TotalEnergies Styrenics EPS, Synthos EPS
Common Misclassification
Can be confused with 390319 (other non-expansible polystyrene) if the 'expansible' characteristic is overlooked, or even 3923 for finished packaging products made from EPS.
Products Classified Under 3903.11
Industry
This code belongs to the Plastics & Rubber industry.
Trade Overview
China, Germany, and South Korea are major exporters, with China, USA, and European Union countries being top importers.
