Biphenyl Flakes (Diphenyl)
Pure biphenyl, also known as diphenyl, supplied in flake form as a white crystalline solid. This cyclic hydrocarbon falls under HTS 2902.90.60.00 due to its chemical structure consisting of two linked phenyl rings and specific presentation in flakes, distinguishing it from other cyclic hydrocarbons.
Technical Grade Biphenyl Flakes
Technical-grade biphenyl flakes with minor impurities, used primarily as a chemical intermediate in dye and pesticide production. Classified under HTS 2902.90.60.00 as it meets the chapter note for separate chemically defined organic compounds in flake form.
Industrial Biphenyl Flakes 99% Purity
99% pure biphenyl flakes for industrial applications like optical brightener synthesis. Falls under HTS 2902.90.60.00 as a chemically defined cyclic hydrocarbon explicitly listed in flake form, per chapter provisions.
Flaked Diphenyl for Dye Manufacturing
Biphenyl in flake form specifically for azo dye production intermediates. Classified in HTS 2902.90.60.00 as it is a separate chemically defined organic compound meeting the precise description, ahead of later chapter headings per classification note.
