Product classification
HS code for Foundry binders: 3824.10
Binders, prepared, for foundry moulds or cores.
Classification of foundry binders under HS 3824.10
Foundry binders are classified under HS code 3824.10. These are prepared chemical products used in the metal casting industry to bind sand grains together to form moulds and cores. This classification falls under Chapter 38, which covers miscellaneous chemical products, and Heading 3824, which is a broad category for chemical products and preparations not elsewhere specified. Subheading 3824.10 is a specific provision for prepared binders for foundry moulds or cores. The classification is based on the fact that these products are "preparations"—mixtures of various chemical substances (such as resins, catalysts, and additives) formulated for a specific industrial function. Because they are ready-to-use or specifically formulated for the foundry process, they are moved from the general chemical headings of Chapter 28 or 29 into this functional heading in Chapter 38.

Codes often confused with 3824.10
Common mistake. Foundry binders are often misclassified under HS code 3907 or 3909 if they are based on synthetic resins like phenolics or epoxies. However, Chapter 39 Note 2(d) generally excludes preparations specifically formulated for use as foundry binders, directing them to 3824.10. They may also be confused with 3824.99 (other chemical products), but since 3824.10 is a specific named subheading for foundry binders, it must be used according to the principle of specificity in GIR 3(a).
Top exporters and importers of HS 382410 (the code used for foundry binders), 2025
In 2025, the largest exporter of HS 382410 (the code used for foundry binders) in UN Comtrade data was Germany, with 21% of world exports; the largest importer in UN Comtrade data was Egypt, with 22% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
