Polystyrene is one of the most widely used synthetic polymers across various industries, playing a vital role in the production of packaging, construction, and industrial products. Owing to properties such as lightness, thermal resistance, flexibility, and insulation, it is extensively used in automotive, home appliances, and electronics. Therefore, customs clearance of polystyrene requires precise knowledge of tariff codes, standards, and document verification.

Immediate & Free Consultation1) Types of Polystyrene, HS Code, and Applications
Depending on the type and grade, polystyrene has different customs tariff codes. Below are the most important types with HS Codes and applications:
1. General-Purpose Polystyrene (GPPS) — HS: 39031100
Features: Transparent, relatively brittle and rigid; easy to mold; suitable for lightweight and disposable products.
Disposable containers and packaging • Acoustic/thermal insulation • Lightweight electronic parts • Model making and decorative items
2. High-Impact Polystyrene (HIPS) — HS: 39031200
Features: Higher impact resistance and flexibility than GPPS; suitable for durable parts.
Appliance housings (refrigerator/washer) • Automotive interior parts • TV and electronics enclosures • Durable toys
3. Expanded Polystyrene (EPS) — HS: 39031900
Features: Expandable into an ultra-light foam with excellent thermal/acoustic insulation; widely used in packaging and construction.
Building insulation • Packaging of sensitive products • Lightweight panels • Product protection in transportation
4. Special/Reinforced Grades — HS: 39039000
Features: Enhanced for specific resistances (chemical/thermal) tailored to specialized industrial applications.
Industrial products requiring high resistance • Chemically resistant coatings • Certain medical equipment
| Polystyrene Type | Short Description | HS Code |
|---|---|---|
| General-Purpose Polystyrene (GPPS) | Transparent, moldable, for light/disposable uses | 39031100 |
| High-Impact Polystyrene (HIPS) | More impact-resistant and flexible than GPPS | 39031200 |
| Expanded Polystyrene (EPS) | Foamed, lightweight, thermal/acoustic insulation | 39031900 |
| Special reinforced grades | Improved chemical/thermal resistance | 39039000 |
Exact classification depends on form of supply, grade, packaging, and end use.
2) Key Points for Clearing Polystyrene from Customs
Document consistency: Prepare the invoice, packing list, and certificate of origin accurately and in compliance with Iranian regulations.
Standards and hygiene: For food-related applications, providing health and compliance certificates is mandatory.
Quality and weight assessment: QC, weight, and volume control are essential to avoid discrepancies.
Taxes and duties: Correct calculation based on the HS Code is crucial to avoid delays/penalties.
