9902.02.20 - Thymol (2-isopropyl-5-methylphenol) (CAS No. 89-83-8) (provided for in subheading 2907.19.40)

This HTS category, 9902.02.20, specifically covers Thymol, also identified by its CAS Number 89-83-8 and chemical name 2-isopropyl-5-methylphenol. While its primary classification is within Chapter 29 (Organic Chemicals), this special provision allows for its identification and potential modification of duties or restrictions under Chapter 99, which deals with temporary legislation and proclamations. Thymol is a naturally occurring phenolic compound, often used in medicinal and cosmetic preparations, as well as a flavoring agent and antiseptic.

As a leaf node within Chapter 99, this category does not have direct subcategories at this level. Its distinction from sibling categories within Chapter 99 lies in its specific designation for Thymol, a chemical compound. Other categories within Chapter 99 typically cover temporary measures for a wide array of goods, often related to trade agreements, agricultural adjustments, or specific import restrictions. This node isolates Thymol for specialized treatment, signaling that its tariff treatment may differ from its standard classification under subheading 2907.19.40 due to temporary legislative actions.
