Synthetic organic tanning substances; inorganic tanning substances; tanning preparations; enzymatic preparations for pre-tanning

cpc code 34330 covers a diverse range of chemical products used in the tanning and leather processing industries. These substances play a crucial role in transforming raw animal hides into high-quality leather materials, which are then utilized across a wide spectrum of industries, from fashion and furniture to automotive and construction. The global demand for these tanning and pre-tanning chemicals continues to grow, driven by the expanding leather goods market and the need for sustainable, environmentally-friendly tanning processes.

The production of the materials covered under cpc code 34330 typically involves a multi-step chemical synthesis process. Synthetic organic tanning substances are often derived from petroleum-based feedstocks, while inorganic tanning substances may be mineral-based. Tanning preparations can combine both organic and inorganic components, often with the addition of enzymes to facilitate the pre-tanning process. Advanced manufacturing techniques, such as continuous flow chemistry and green chemistry principles, are increasingly being adopted to improve the efficiency and sustainability of these production methods.

The main inputs required for the production of cpc code 34330 materials include a variety of organic and inorganic chemicals, such as aromatic compounds, aliphatic compounds, and various mineral salts. Specialized equipment, such as reactors, distillation columns, and drying systems, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical engineering, analytical chemistry, and quality control.

The outputs of cpc code 34330 are primarily consumed by the 15110 Tanning and dressing of leather; dressing and dyeing of fur industry, where they are used to transform raw animal hides into finished leather products. These tanning and pre-tanning chemicals may also find applications in other industries, such as 20110 Manufacture of basic chemicals, fertilizers and nitrogen compounds, plastics and synthetic rubber in primary forms and 20200 Manufacture of pesticides and other agrochemical products, where they can be used as intermediates or specialty chemicals.
