9902.01.84 - 1,6,7,8,9,14,15,16,17,17,18,18-Dodecachloropentacy- clo[12.2.1.16,9.02,13.05,10]octadeca-7,15-diene (CAS No. 13560-89-9) (provided for in subheading 2903.89.31)

This HTS category, 9902.01.84, pertains to a specific, highly chlorinated organic compound identified as 1,6,7,8,9,14,15,16,17,17,18,18-Dodecachloropentacyclo[12.2.1.1^6,9.0^2,13.0^5,10]octadeca-7,15-diene, also recognized by its CAS Number 13560-89-9. It is crucial to note that this classification is designated under Chapter 99, which houses temporary legislation and special provisions, including restrictions proclaimed pursuant to Section 22 of the Agricultural Adjustment Act. This signifies that the importation of this substance is subject to specific, temporary trade policies and potential additional restrictions beyond standard tariff classifications.

As a leaf node within the HTS, this category does not have further subcategories. Its inclusion under Section XXII and Chapter 99 underscores its unique regulatory status. Unlike the general tariff classifications found in earlier chapters (e.g., Chapter 29 for organic chemicals), this entry is specifically for a controlled substance with a designated, temporary duty rate or restriction, reflecting a policy decision rather than a general product grouping. The "provided for in subheading 2903.89.31" note is vital; it indicates that while the substance is chemically described, its present importation circumstances necessitate its classification in this special provision. Importers must consult the specific trade agreements and proclamations associated with this HTS code to understand all applicable duties, quotas, or prohibitions.
