9902.03.34 - Methoxyacetic acid (CAS No. 625-45-6) (provided for in subheading 2918.99.50)

This HTS category, 9902.03.34, specifically covers Methoxyacetic acid, identified by its CAS number 625-45-6. This classification falls under Chapter 99, which pertains to temporary legislation and special provisions. The "provided for in subheading 2918.99.50" notation indicates that while Methoxyacetic acid has a primary classification within the standard HTS structure (likely for organic compounds with carboxylic acid functional groups and other oxygen hetero-atom substituents), this Chapter 99 code represents a specific, temporary tariff or trade measure applied to it. This often involves duties, quotas, or other restrictions implemented under trade agreements or specific agricultural legislation.

As a leaf node, this category does not have further subdivisions. Its uniqueness lies in its application of special classification provisions to a specific chemical compound. Unlike sibling categories at the Chapter 99 level, which might cover a broader range of temporary measures or other specific goods subject to special treatment, 9902.03.34 is narrowly focused on Methoxyacetic acid. The primary purpose of this code is to flag Methoxyacetic acid for specific import/export procedures dictated by temporary legislative actions, rather than its general chemical properties which are addressed in its principal HTS classification.

Therefore, when encountering HTS 9902.03.34, importers and exporters should recognize that this is not a general classification for organic acids, but a directive for specific tariff treatment. The relevant information for classification under this code is the identity of the good as Methoxyacetic acid and the current status of the temporary legislation associated with this specific HTS number. Consultation of the most recent trade regulations and the official HTS annotations is crucial for accurate compliance.
