9902.03.46 - Dimethyl carbonate (CAS No. 616-38-6) (provided for in subheading 2920.90.51)

HTS code 9902.03.46 specifically covers Dimethyl carbonate (CAS No. 616-38-6). This classification is found within Chapter 99, which is designated for temporary legislation, modifications pursuant to trade agreements, and additional import restrictions. Its inclusion under this chapter signifies that its tariff treatment may be subject to change based on specific proclamations or legislative actions, often differing from its standard classification under the main body of the HTS.

Unlike other categories within Chapter 99 which might cover a broad range of temporary measures or specific trade agreement provisions, this particular subheading is singularly focused on a chemical compound, Dimethyl carbonate. Its presence here indicates a specific, likely temporary, duty rate or restriction applied to this particular chemical, potentially for policy, trade, or domestic industry protection reasons.

As a leaf node, HTS code 9902.03.46 has no further subcategories. The classification is final at this level, meaning that any Dimethyl carbonate imported under this provision will be subject to the specific rules and duties associated with this exact code. It is important to note that this code references subheading 2920.90.51 for its primary classification, suggesting that the 9900 series code represents a modification or special provision applied to the goods otherwise classified under 2920.90.51.
