9902.11.36 - 4-tert-Butylphenol; formaldehyde; 4-[2-(4-hydroxyphenyl)propyl]phenol (CAS No. 54579-44-1) (provided for in subheading 3909.40.00)

This HTS classification, 9902.11.36, pertains to specific chemical compounds: 4-tert-Butylphenol, formaldehyde, and 4-[2-(4-hydroxyphenyl)propyl]phenol (CAS No. 54579-44-1). These are notable for being specifically provided for within subheading 3909.40.00, indicating their primary use or nature as components or precursors related to amino resins, phenolic resins, and polycondensation products. This temporary classification is enacted under Section XXII of the Harmonized Tariff Schedule, dealing with special classification provisions, temporary legislation, and modifications related to trade agreements and agricultural adjustment acts.

Distinguishing this category from its sibling entries requires understanding its placement within Chapter 99. Chapter 99 codes are generally reserved for temporary modifications, special provisions, or additional import restrictions and do not represent standard product categories like those found in Chapters 1 through 97. While other entries in Chapter 99 might cover temporary importations or specific quota restrictions on various goods, 9902.11.36 specifically targets these identified phenolic compounds, signaling a unique regulatory treatment or temporary measure applied to them, rather than a broad product group.

As this node is a leaf node, there are no further subcategories to introduce. Classification under 9902.11.36 is definitive for the specified chemicals when they are subject to the temporary provisions outlined by the encompassing Chapter 99. Importers should ensure that the goods precisely match the chemical identity and CAS number provided, and be aware of any accompanying documentation or conditions required under the temporary legislation.
