HTS CHAPTER

Chapter 38: Miscellaneous Chemical Products

HTS Chapter 38, titled "Miscellaneous Chemical Products," encompasses a diverse range of chemical substances that do not fall under other specific categories. This chapter includes products such as industrial cleaning agents, chemical preparations used in agriculture, and various types of adhesives and sealants. Common examples include surfactants, herbicides, insecticides, and certain types of specialty coatings. Industries like agriculture, manufacturing, and pharmaceuticals often import these goods to enhance production processes, improve product performance, or meet regulatory standards. Importers should be aware of regulatory considerations, such as compliance with the Environmental Protection Agency (EPA) regulations for pesticides and adherence to safety data sheet (SDS) requirements for hazardous materials. Additionally, some chemicals may be subject to import restrictions or require specific documentation to ensure safety and compliance. Understanding these nuances within Chapter 38 is crucial for U.S. importers to navigate the complexities of international trade effectively and maintain compliance with all pertinent regulations.
