HS v2022 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, providing essential inputs for a wide range of consumer and industrial goods.

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 incorporate enzymatic treatments for pre-tanning processes. These specialized formulations are designed to effectively remove impurities, condition the material, and impart desired properties such as color, texture, and resistance to wear and tear.

Production inputs

The tanning industry relies on a range of raw materials and resources. Synthetic tanning agents are produced from petrochemical feedstocks, while natural tanning substances may be derived from tree bark, leaves, or other plant-based sources. Specialized machinery and equipment, such as tanning drums, drying chambers, and finishing tools, are also essential for the various stages of tanning and preparation. Additionally, the industry utilizes a variety of auxiliary chemicals, dyes, and additives to achieve specific product characteristics.

Production outputs

The primary outputs of HS code 3202 are tanning substances and preparations, which are then consumed by the 4101 Hides and skins and 5101 Wool, not carded or combed industries for the production of leather and textile goods. These tanning materials are crucial for imparting desirable properties to the final products, such as durability, color, and resistance to environmental factors. The tanning industry's outputs are essential inputs for a wide range of consumer and industrial applications, including footwear, apparel, furniture, and automotive upholstery.
