Product classification
HS code for Argol: 2307.00
Wine lees, argol.
Classification of argol under HS 2307.00
Argol is classified under HS code 2307.00. This classification is based on the product's origin as a byproduct of the winemaking process. Argol, also known as crude tartar, is a crystalline deposit that forms on the sides of vats during the fermentation and storage of wine. It consists primarily of potassium bitartrate. Under the Harmonized System, Chapter 23 is dedicated to residues and waste from the food industries. Heading 2307 specifically names 'Wine lees; argol.' Because argol is a raw, unrefined residue, it is placed here rather than in the chemical chapters. The classification follows GRI 1, as the heading text explicitly identifies the substance. Even if the argol has been collected and dried, as long as it has not undergone extensive chemical refining to produce pure tartaric acid or pure potassium bitartrate, it remains within this classification. It is considered a valuable secondary product for the production of tartrates in the chemical industry.

Codes often confused with 2307.00
Common mistake. Argol is often misclassified under HS code 2918.12, which is the code for pure tartaric acid. While argol is a source of tartaric acid, the 2918 code is reserved for chemically defined organic acids. Similarly, refined potassium bitartrate (cream of tartar) is classified under 2918.13. Another error involves 3824.99, a general category for chemical mixtures, but since argol is specifically named in 2307.00, that heading takes precedence according to the principle of specificity.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
