HS v2017 Code: 3202

About tanning substances; synthetic organic or inorganic tanning substances; tanning preparations, whether or not containing natural tanning substances, enzymatic preparations for pre-tanning

HS code 3202 covers a diverse range of tanning substances and preparations used in the leather and textile industries. These materials play a crucial role in the processing and treatment of raw hides and fabrics, transforming them into high-quality, durable products. The tanning industry is a vital component of the global supply chain, supporting a wide range of downstream industries, from fashion and furniture to automotive and construction.

Production process

The production of tanning substances and preparations involves several key steps. Synthetic organic or inorganic tanning agents are typically manufactured through chemical synthesis, while natural tanning substances may be extracted from plant materials. Tanning preparations can also include enzymatic pre-tanning agents, which help to prepare the raw materials for the tanning process. These preparations are then formulated and blended to meet the specific requirements of different applications.

Production inputs

The main inputs for the tanning industry include a variety of raw materials, such as chemicals, plant extracts, and enzymes. Specialized machinery and equipment, such as reactors, mixers, and drying systems, are also essential for the production of tanning substances and preparations. Additionally, the industry relies on a skilled workforce, including chemists, process engineers, and technicians, to ensure the quality and consistency of the final products.

Production outputs

The primary outputs of the tanning industry under HS code 3202 are tanning substances, synthetic organic or inorganic tanning agents, and tanning preparations. These materials are then consumed by the 4101 Hides and skins and 5301 Flax industries, where they are used to process and treat raw materials for the production of leather, textiles, and other related products.
