9902.11.12 - Mixtures of α-(3-(3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl) -1-oxopropyl)-ω-hydroxy-poly (oxy-1,2-ethanediyl) (CAS No. 104810-48-2); α-(3-(3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl) -1-oxopropyl)-ω- (3-(3-(2H-benzotriazol-2-yl) -5-(1,1-dimethylethyl) -4-hydroxyphenyl) -1-oxopropoxy)-poly (oxy-1,2-ethanediyl) (CAS No. 104810-47-1); and polyethylene glycol (CAS No. 25322-68-3) (provided for in subheading 3907.20.00)

This HTS category, 9902.11.12, specifically covers certain mixtures and individual components that are subject to temporary modifications or restrictions proclaimed under trade agreements legislation or Section 22 of the Agricultural Adjustment Act. The core components of this classification are specific chemical compounds: mixtures of polymer derivatives of alpha-(3-(3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl)-1-oxopropyl)-omega-hydroxy-poly(oxy-1,2-ethanediyl) and alpha-(3-(3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl)-1-oxopropyl)-omega-(3-(3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl)-1-oxopropoxy)-poly(oxy-1,2-ethanediyl), identified by CAS numbers 104810-48-2 and 104810-47-1 respectively, along with polyethylene glycol (CAS No. 25322-68-3). Notably, these polyethylene glycols are also provided for under subheading 3907.20.00, indicating a specific tariff treatment within this Chapter 99 provision.

Distinguishing this category from its siblings within Chapter 99 requires understanding the precise nature of the goods. While other Chapter 99 headings may cover temporary import restrictions or modifications for various goods, this particular subheading is narrowly defined by the specific chemical substances and their CAS numbers. It is not a broad category for all restricted chemical compounds but rather targets these particular benzotriazole derivatives and polyethylene glycols, suggesting a specialized regulatory purpose. The inclusion of specific CAS numbers serves as a precise identifier, ensuring that only these exact chemical entities fall under this classification, rather than general categories of polymers or other chemical substances.

As this node is a leaf node, it does not have subcategories. Therefore, the focus is on the definitive classification of the enumerated chemical mixtures and compounds. Importers must ensure that the goods precisely match the chemical descriptions and CAS numbers provided, as this HTS code signifies a specific regulatory treatment, potentially including duties, quotas, or other import restrictions, distinct from their classification under the standard HTS Chapters. Verification of the chemical composition and origin of the imported material is crucial for correct customs declaration.
