Products classified under HTS 2908.99.40.00
2-sec-Butyl-4,6-dinitrophenol (DNBP)
2-sec-Butyl-4,6-dinitrophenol, commonly known as DNBP or dinoseb, is a nitrated phenol derivative used as a herbicide for post-emergence control of broadleaf weeds in crops. It falls under HTS 2908.99.40.00 as a dinitrobutylphenol, matching the chemical structure with two nitro groups and a butyl chain on a phenolic base. This pure organic compound is supplied as technical grade material for agricultural formulations.
Dinoseb Sodium Salt
Dinoseb sodium salt is the sodium salt form of 2-sec-butyl-4,6-dinitrophenol, a water-soluble variant used in herbicide formulations for better handling and application. Classified under HTS 2908.99.40.00 per chapter note 5(C)(1), as inorganic salts of organic compounds follow the parent organic compound's heading. It's a chemically defined compound with two nitro groups on a butylphenol backbone.
2-tert-Butyl-4,6-Dinitrophenol
2-tert-Butyl-4,6-dinitrophenol is an isomer of dinitrobutylphenol used in specialty herbicide applications and as a chemical intermediate. It precisely matches HTS 2908.99.40.00 due to its dinitrated butylphenol structure, a separate chemically defined organic compound. Primarily imported as high-purity powder for synthesis.
Dinoseb Ammonium Salt
The ammonium salt of dinoseb (dinitrobutylphenol) offers improved solubility for foliar herbicide sprays in agriculture. HTS 2908.99.40.00 applies via chapter note 5(C)(1) for salts of the parent nitrated phenol compound. It's imported as a crystalline solid for formulation into crop protection products.
4,6-Dinitro-2-(1-methylpropyl)phenol
This synonym for DNBP, 4,6-dinitro-2-(1-methylpropyl)phenol, is a key active ingredient in selective herbicides for cereals. It qualifies under HTS 2908.99.40.00 as a chemically pure dinitrobutylphenol without impurities altering its classification. Supplied in drums for industrial pesticide production.
Dinoterb (2-tert-Butyl-4,6-Dinitrophenol) Technical Grade
Dinoterb technical grade is 2-tert-butyl-4,6-dinitrophenol at 95-98% purity, used as a herbicide for grass weed control. Classified in HTS 2908.99.40.00 as it meets the dinitrobutylphenol definition, with minor impurities allowed per chapter note 2(a). Ideal for manufacturing emulsifiable concentrates.
DNBP Potassium Salt
Potassium salt of dinitrobutylphenol (DNBP) enhances water dispersibility in herbicide tank mixes. Per HTS 2908.99.40.00 and chapter note 5(C), salts classify with the parent dinitrobutylphenol. Imported as flakes for quick dissolution in ag applications.
