9902.02.37 - 2-(Hydroxymethyl)-2-(prop-2-enoxymethyl) propane-1,3-diol (CAS No. 91648-24-7) (provided for in subheading 2909.49.60)

This HTS category, 9902.02.37, pertains to a specific chemical compound: 2-(Hydroxymethyl)-2-(prop-2-enoxymethyl) propane-1,3-diol, identified by CAS No. 91648-24-7. This classification falls under Chapter 99, which encompasses temporary legislation and modifications related to trade agreements and additional import restrictions. The specific inclusion of this chemical within Chapter 99 indicates it is subject to special regulatory treatment, distinct from its primary classification under subheading 2909.49.60, which deals with other ethers and their halogenated, sulfonated, nitrated, or nitrosated derivatives.

Unlike the broad categories of live animals or other general goods found at the root level of the HTS database, this node represents a highly specific chemical substance. Its inclusion in Chapter 99 signifies that its import may be subject to temporary restrictions, quotas, or specific documentation requirements beyond standard customs procedures. The temporary nature of this classification suggests it is likely tied to specific trade policies or adjustments that are not permanent.

As this node is a leaf node, there are no further subcategories. Therefore, classification within 9902.02.37 is definitive for the described chemical. Importers should ensure that the substance they are declaring precisely matches the chemical name and CAS number provided, and they must be aware of any accompanying temporary regulations or restrictions associated with this Chapter 99 entry.
