HS v2017 Code: 2307

About wine lees; argol

HS code 2307 covers wine lees and argol, which are byproducts of the wine production industry. These materials have important applications in various industries, making them a significant part of the global trade landscape. Wine lees, the sediment that settles at the bottom of wine vats, are a valuable source of tartaric acid, potassium, and other compounds used in the production of 2918 Carboxylic acids, 2915 Acyclic monocarboxylic acids, and other chemical products. Argol, on the other hand, is a crude form of potassium bitartrate that is extracted from wine lees and has applications in the 2836 Inorganic chemical compounds industry.

Production process

The production of wine lees and argol involves the separation and processing of these byproducts during the winemaking process. After the fermentation of grape juice, the wine lees settle to the bottom of the vat. These lees are then collected and either sold directly or further processed to extract the desired compounds, such as tartaric acid and potassium bitartrate. The extraction of argol from wine lees typically involves a series of filtration, crystallization, and drying steps to purify the potassium bitartrate.

Production inputs

The main inputs required for the production of wine lees and argol are the raw materials from the wine industry, primarily grape juice and wine. Additionally, the production process may require specialized equipment such as filtration systems, centrifuges, and crystallization tanks. Energy sources, such as electricity or natural gas, are also necessary for the various processing steps.

Production outputs

The primary outputs of HS code 2307 are wine lees and argol. These materials are then used as inputs in various other industries. Wine lees are used in the production of 2918 Carboxylic acids, 2915 Acyclic monocarboxylic acids, and other chemical products. Argol, on the other hand, is used in the 2836 Inorganic chemical compounds industry, where it serves as a source of potassium bitartrate.
