Terbutryn is an organic chemical with the IUPAC name (4E)-4-(Ethylimino)-N-(2-methyl-2-propanyl)-6-(methylsulfanyl)-1,4-dihydro-1,3,5-triazin-2-amine. While its primary HTS classification is found under subheading 2933.69.60, this chapter 99 code indicates it is subject to specific temporary legislation, trade agreement modifications, or additional import restrictions under Section 22 of the Agricultural Adjustment Act.

As a leaf node within Chapter 99, this classification does not have further subcategories. Its purpose is to identify terbutryn when it falls under these special provisions.
