9902.03.79 - 2-Ethyl-6-methylaniline (CAS No. 24549-06-2) (provided for in subheading 2921.49.50)

This HTS category, 9902.03.79, specifically covers 2-Ethyl-6-methylaniline (CAS No. 24549-06-2). This chemical compound, a substituted aniline derivative, is classified here under the temporary legislation provisions of Chapter 99. Its inclusion in this chapter signifies that it is subject to specific temporary modifications or additional import restrictions proclaimed pursuant to trade agreements legislation or Section 22 of the Agricultural Adjustment Act. The reference to subheading 2921.49.50 indicates its primary classification within the broader chemical chapters before being subject to these special provisions.

As a leaf node, this category does not have further subcategories. Its specificity is thus critical for accurate declaration. Importers and exporters must ensure that the substance being declared precisely matches the chemical identity and CAS number of 2-Ethyl-6-methylaniline. Any variations in chemical structure or impurities could potentially lead to classification under a different HTS code, potentially affecting duty rates, import eligibility, and compliance requirements.

The presence of this specific chemical under Chapter 99 signifies that its importation is governed by rules beyond the standard classification under chemical chapters. This often pertains to national security, agricultural protection, or other policy-driven import controls. Therefore, adherence to the specific requirements associated with this HTS code, including any documentation or licensing mandated by the temporary provisions, is paramount for smooth customs clearance.
