About amine-function compounds; aromatic amines and their derivatives; o-, m-, p-phenylenediamine, diaminotoluenes and their derivatives; salts thereof

HS code 292151 covers a diverse range of aromatic amine compounds, which are essential building blocks in the production of various chemicals, pharmaceuticals, and specialty materials. These compounds play a crucial role in the global chemical industry, finding applications in the synthesis of dyes, pigments, pesticides, and a wide array of other products that are integral to modern life. As such, the trade and production of these amine-function compounds are of significant economic importance, with their demand closely tied to the performance and growth of numerous downstream industries.

Production process

The production of the amine-function compounds covered under HS code 292151 typically involves a series of chemical reactions, including nitration, reduction, and purification steps. The key process generally starts with the nitration of aromatic hydrocarbons, such as benzene or toluene, to form nitro-aromatic compounds. These nitro-compounds are then subjected to catalytic hydrogenation, which reduces the nitro group to an amino group, yielding the desired amine-function compounds. Depending on the specific product, additional purification and separation steps may be necessary to obtain the final high-purity material.

Production inputs

The production of HS code 292151 compounds requires a range of raw materials, including aromatic hydrocarbons, such as benzene and toluene, as well as various reducing agents, catalysts, and solvents. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the efficient and high-quality manufacture of these amine-function compounds. The availability and cost of these key inputs can significantly impact the overall competitiveness and profitability of the industry.

Production outputs
