Acids; aromatic polycarboxylic acids; other esters of orthophthalic acids

HS v2017 Code: 291734

About acids; aromatic polycarboxylic acids; other esters of orthophthalic acids

HS code 291734 covers a range of aromatic polycarboxylic acids and their esters, which are essential chemicals used in various industries. These compounds play a crucial role in the production of plastics, dyes, pharmaceuticals, and other important materials. As a key component of the broader organic chemicals industry, this code represents a significant segment of international trade and economic activity.

Production process

The production of the chemicals covered under HS code 291734 typically involves a multi-step process. The starting point is often the oxidation of aromatic hydrocarbons, such as xylene or naphthalene, to form the desired polycarboxylic acid. This is then further processed, often through esterification reactions, to yield the final esters and other derivatives.

Production inputs

The main inputs required for the production of the chemicals under this code include aromatic hydrocarbons, such as 290243 xylene and 290215 naphthalene, as well as various alcohols and other reagents needed for the esterification and other chemical processes. Additionally, specialized production equipment, such as reactors, distillation columns, and purification systems, are essential for the manufacturing of these products.

Production outputs

The chemicals produced under HS code 291734 are used as intermediates in the production of a wide range of other products. The aromatic polycarboxylic acids and their esters find applications in the manufacture of plastics, dyes, pigments, and pharmaceutical compounds, among other uses. Some of the other HS codes that may consume the outputs of this industry include 390120 Polymers of ethylene, in primary forms, 320411 Synthetic organic coloring matter and preparations based thereon, and 300490 (Medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale).

Revisions to 291734
