HS Code 3824.99 – Chemical products, mixtures and preparations; n.e.c. heading 3824

HS code 3824.99 is the 6-digit subheading for chemical products, mixtures and preparations, n.e.c. heading 3824. It is used for industrial cleaning solutions, anti-corrosion coatings, laboratory reagents, water treatment chemicals and textile auxiliaries.

What HS 3824.99 covers

This is a broad 'basket' HS code for a vast array of chemical products, mixtures, and preparations not specified elsewhere in heading 3824. It encompasses an incredibly diverse range of industrial chemicals, from specialized cleaning agents and anti-corrosion preparations to laboratory reagents, water treatment chemicals, and various additives for manufacturing processes. Virtually every sector of the global economy, from agriculture to high-tech industries, relies on products classified here. Importers and exporters include major chemical companies, distributors, and end-users across all industrial sectors. Key aspects of trade under this code are the sheer diversity of products, the necessity for precise chemical identification to avoid misclassification, and compliance with a myriad of safety, environmental, and industry-specific regulations that vary widely by product type and application.

Codes often confused with 3824.99

Common mistake. This code is often a 'last resort' and can be confused with more specific chemical preparations (e.g., 382489 for SCCPs) or even products in other chapters if their primary function is different, such as pharmaceuticals (Chapter 30).

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).
