3915.20.00.00 - Of polymers of styrene

This HTS category, 3915.20.00.00, specifically classifies waste, parings, and scrap derived from polymers of styrene. This includes materials such as polystyrene (PS), acrylonitrile butadiene styrene (ABS), and styrene-acrylonitrile (SAN) that are in a waste or scrap form, unfit for their original intended use but potentially recyclable or usable as raw material in other manufacturing processes. Examples include offcuts from styrene-based plastic manufacturing, rejected styrene molded products, or collected post-consumer styrene plastic waste.

It is crucial to distinguish this category from its siblings. HTS 3915.10.00.00 covers waste, parings, and scrap of polymers of ethylene (e.g., polyethylene), while HTS 3915.30.00.00 pertains to waste and scrap from polymers of vinyl chloride (e.g., PVC). HTS 3915.90.00 encompasses waste and scrap from all other plastic polymers not specifically enumerated in the preceding subheadings. Therefore, classification under 3915.20.00.00 hinges on the definitive identification of styrene as the primary polymer in the waste material.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification is directly determined by the material composition of the waste, parings, or scrap, which must be predominantly composed of styrene polymers. The focus for customs purposes is on the material identity of the waste product to ensure accurate duty assessment and trade statistics.
