Atactic Polystyrene Granules from United States
Atactic polystyrene granules are an amorphous, non-crystalline form of polystyrene supplied in primary form (granules). They are classified under tariff item 3903.19.00 as 'other' polystyrene, since they are not specifically named in any other subheading of heading 39.03. These granules are commonly used as blend modifiers to improve clarity and impact resistance in various plastic products.

Import Tips
• Ensure the granules are in primary form (e.g
• granules, pellets) and not mixed with other polymers that could change classification
• Keep a technical data sheet showing the styrene content and amorphous nature to support the tariff classification
• Verify whether the goods are subject to any Canadian anti-dumping or countervailing measures before shipping
