High Impact Polystyrene Resin (HIPS) from United States
High impact polystyrene resin (HIPS) is a copolymer of styrene and butadiene, with butadiene content typically under 5% by weight. It is classified under tariff item 3903.19.00 as 'other' polystyrene, since the styrene monomer unit predominates and the butadiene content is below the threshold for other subheadings. HIPS is used for applications requiring impact resistance, such as appliance housings and toys.

Import Tips
• Provide a certificate of analysis showing the butadiene content is less than 5% by weight to support classification under 3903.19.00
• Ensure the resin is in primary form (pellets or granules)
• Check if the resin is subject to any Canadian chemical regulations, such as those under CEPA
