Overview
This HTS category, 9902.11.18, specifically covers sulfonated polyethylene terephthalate, identified by CAS No. 63534-56-5. This material is a modified form of polyethylene terephthalate (PET) that has undergone a sulfonation process, altering its chemical properties. It is important to note that while classified within Chapter 99, which pertains to temporary legislation and trade agreement modifications, the product itself is provided for in subheading 3907.60.00, indicating its primary classification based on material composition.
As a leaf node, this category does not have further subdivisions. Its distinction from other categories within Chapter 99 lies in its specific identification of a chemical compound with a particular CAS number and processing (sulfonation). While other categories in Chapter 99 might deal with temporary restrictions or modifications on various goods, this entry is narrowly focused on this specific sulfonated polyester resin, emphasizing its unique chemical identity and the temporary legislative framework under which it is managed. Its classification is therefore crucial for accurately applying any special provisions or restrictions that may be in effect for this particular product.
