Phenol or phenol-alcohol derivatives, sulphonated, nitrated or nitrosated derivatives thereof; 4,6-dinitro-o-cresol (DNOC (ISO)) and its salts

HS v2017 Code: 290892

About phenol or phenol-alcohol derivatives, sulphonated, nitrated or nitrosated derivatives thereof; 4,6-dinitro-o-cresol (dnoc (iso)) and its salts

HS code 290892 covers a range of chemical compounds derived from phenol or phenol-alcohol. These substances are important intermediates in the production of various pharmaceuticals, pesticides, dyes, and other specialty chemicals. The global market for these derivatives is driven by the growing demand from the pharmaceutical, agrochemical, and specialty chemical industries, making this code a crucial component of the broader chemical supply chain.

Production process

The production of the chemicals covered under HS code 290892 typically involves a multi-step process. The starting point is the sulfonation, nitration, or nitrosation of phenol or phenol-alcohol compounds. This is often followed by further purification and separation steps to obtain the desired derivatives, such as 4,6-dinitro-o-cresol (DNOC) and its salts.

Production inputs

The main inputs required for the production of the chemicals under HS code 290892 include phenol, phenol-alcohol, and various reagents for the sulfonation, nitration, or nitrosation processes. Additionally, specialized equipment such as reactors, distillation columns, and purification systems are necessary to ensure the quality and purity of the final products.

Production outputs

The outputs of the industry covered by HS code 290892 include a range of sulfonated, nitrated, or nitrosated phenol or phenol-alcohol derivatives, which are then used as intermediates in the production of 300490 (Medicaments (excluding goods of heading 30.02, 30.05 or 30.06) consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses (including those in the form of transdermal administration systems) or in forms or packings for retail sale), 380810 (Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, put up in forms or packings for retail sale or as preparations or articles (for example, sulphur-treated bands, wicks and candles, and fly-papers)), and other specialty chemicals.
