9902.06.13 - 2,3-Pyridinedicarboxylic acid (CAS No. 89-00-9) (provided for in subheading 2933.39.61)

This HTS chapter, specifically subheading 9902.06.13, pertains to temporary import restrictions related to 2,3-Pyridinedicarboxylic acid (CAS No. 89-00-9). This classification is not for general trade but rather for specific goods that are subject to additional import limitations as proclaimed under Section 22 of the Agricultural Adjustment Act, as amended, or other trade agreement legislation. The primary purpose of this chapter is to manage or restrict the importation of certain commodities for reasons of national economic policy or agricultural protection.

Unlike the broad categories found in earlier chapters of the HTS (e.g., Chapter 01 for live animals), this subheading falls under Section XXII, which deals with special provisions and temporary measures. Therefore, its scope is highly specific and dictated by the particular proclamations or agreements that established it. The existence of the parenthetical note "(provided for in subheading 2933.39.61)" indicates that the underlying chemical substance, 2,3-Pyridinedicarboxylic acid, is normally classified elsewhere under the HTS but is subject to these additional, temporary restrictions when imported.

As a leaf node, subheading 9902.06.13 does not have further subdivisions. Its classification is definitive for 2,3-Pyridinedicarboxylic acid when subject to the stipulated temporary legislation. Importers must refer to the specific text of the proclamations or trade agreements referenced by this classification to understand the exact nature of the restrictions, which could include quotas, specific documentation requirements, or outright prohibitions, in addition to any regular duties applicable to the substance under its primary HTS classification.
