9902.08.98 - Resin cement based on calcium carbonate and silicone resins (CAS Nos. 471-34-1 and 68037-83-2) (provided for in subheading 3214.10.00)

This HTS category, 9902.08.98, specifically covers resin cements formulated with calcium carbonate and silicone resins. The inclusion of CAS numbers 471-34-1 and 68037-83-2 provides precise chemical identification for these key components. Importantly, this classification is for informational and temporary purposes, as it indicates the provision of these goods under subheading 3214.10.00 of the primary HTS structure, which deals with putties, glaziers' putty, stoppings, and mastics.

As a category within Section XXII, Chapter 99, this entry signifies temporary legislation or modifications. It does not directly represent a broad commodity group like the numerous Chapter 01 headings for live animals. Instead, it pertains to specific, potentially duty-altering or restriction-related treatments for a particular type of resin cement. The distinction from sibling categories is evident in its highly specialized nature, addressing a specific chemical composition and its temporary classification status rather than a general trade good.

Given that this is a leaf node, there are no further subdivisions under 9902.08.98. Classification within this entry is contingent upon the product meeting the described chemical composition and being subject to the specific temporary provisions outlined for this code. Users should consult the relevant trade agreements, legislation, or proclamations referenced in Section XXII and Chapter 99 to understand the full implications and requirements for goods classified under this HTS code.
