Overview
This HTS category, 9902.11.37, specifically classifies a mixture composed of polymers derived from formaldehyde and 1,3-benzenediol (also known as resorcinol), in a 1:1 ratio, alongside unreacted 1,3-benzenediol. The CAS numbers provided, 24969-11-7 for the polymer mixture and 108-46-3 for the unreacted component, serve as precise identifiers for these chemical substances. This classification is within Chapter 99, which pertains to temporary legislation and modifications, indicating that this specific duty rate or restriction is not a permanent fixture in the tariff schedule.
Distinguishing this category from its siblings, which are predominantly comprised of live animals in Chapter 01, is straightforward due to the fundamental difference in product type. Chapter 01 addresses living creatures, while 9902.11.37 deals with a specific chemical mixture. The "provided for in subheading 3909.40.00" note indicates that the underlying classification for these polymers, absent the temporary provisions, would be under Chapter 39 (Plastics and articles thereof), specifically within the group of amino resins, phenolic resins, and polyurethanes. This category is unique in its treatment within the temporary provisions of Chapter 99, focusing on a particular chemical composition with specific import considerations.
As a leaf node within the HTS database, this classification has no further subcategories. Therefore, the focus is on understanding the precise nature of the chemical mixture as defined by its components and their CAS numbers. Classification under this provision will depend on the importer's ability to demonstrate that the imported goods precisely match the description of the polymer mixture of formaldehyde-1,3-benzenediol and unreacted 1,3-benzenediol as specified. This often requires accompanying laboratory analysis or manufacturer certifications to confirm the identity and composition of the product being imported.
