3915.90.00.10 - Of polyethylene terephthalate (PET) plastics

This HTS category, 3915.90.00.10, specifically classifies waste, parings, and scrap of plastics that are composed of polyethylene terephthalate (PET). This includes material remnants generated during the manufacturing or processing of PET, such as production scrap, offcuts, and used PET articles that are intended for recycling or disposal. The key distinguishing factor for this classification is the material composition – the presence of PET is paramount.

Compared to its sibling category, 3915.90.00.90 ("Other"), this classification is reserved exclusively for PET-based plastic waste. The "Other" category would encompass waste and scrap from any plastic material *not* specifically identified by a preceding subheading, which could include a wide variety of other polymers. Therefore, if the plastic waste is definitively identified as PET, it falls under this heading, and not the broader "Other" category for miscellaneous plastic waste.

As this is a leaf node in the HTS structure, there are no further subcategories within 3915.90.00.10. Classification decisions at this level will rely on confirming the presence and primary composition of polyethylene terephthalate in the waste or scrap material. This often involves reviewing supplier declarations, analytical reports, or visual inspection of the material's characteristics.
