9902.06.28 - 3-tert-Butyl-5-chloro-6-methyluracil (Terbacil) (CAS No. 5902-51-2) (provided for in subheading 2933.59.10)

This HTS category, 9902.06.28, specifically classifies the herbicide known as 3-tert-Butyl-5-chloro-6-methyluracil, also recognized by its CAS number 5902-51-2 and common trade name Terbacil. It is important to note that this classification is made *for the purpose of* subheading 2933.59.10, indicating that while Terbacil falls under the broader chemical classifications of Chapter 29, its temporary or specific import treatment is governed by Chapter 99 provisions. This chapter addresses temporary legislation, modifications made pursuant to trade agreements, and additional import restrictions enacted under Section 22 of the Agricultural Adjustment Act.

The primary function of Terbacil is as a selective herbicide, primarily used for pre-emergence or early post-emergence control of broadleaf and grassy weeds in various agricultural applications, including sugarcane, citrus, and mint. Its classification within Chapter 99 signifies a potential for specific import regulations, duty rates, or quantity limitations that deviate from its standard classification within the chemical chapters of the HTS. This temporary provision is distinct from other chemical compounds that may be classified under Chapter 29 without such specific import controls.

As this HTS code is a leaf node, it does not contain further subcategories. Its purpose is to provide a precise entry point for the specific chemical compound, Terbacil, allowing for the accurate application of any temporary or special import provisions that may be in effect. Understanding the context of Section 22 of the Agricultural Adjustment Act and trade agreement legislation is crucial for correctly interpreting the import requirements associated with this classification.
