Product classification
HS code for Core binders: 3824.10
Binders, prepared, for foundry moulds or cores.
Classification of core binders under HS 3824.10
Core binders used in industrial foundry applications are classified under HS code 3824.10. This classification is situated within Chapter 38, which encompasses miscellaneous chemical products. Heading 3824 is a broad category for chemical products and preparations of the chemical or allied industries that are not specified elsewhere in the nomenclature. Subheading 3824.10 is specifically reserved for "Prepared binders for foundry moulds or cores." These substances are essential in the metal casting process, acting as the adhesive agent that holds sand or other refractory materials together to create the internal shapes (cores) and external forms (moulds). The classification depends on the product being a "prepared" mixture, meaning it has been formulated specifically for foundry use. This includes a wide range of chemical bases, from synthetic resins to specialized oil-based preparations, provided they are intended for the binding of foundry sand.

Codes often confused with 3824.10
Common mistake. Core binders are often confused with HS code 3506, which covers prepared glues and other prepared adhesives. While binders do have adhesive properties, the specific industrial application for foundries dictated by 3824.10 takes precedence over the general adhesive heading. Another common error is using HS code 3806, which covers rosin and resin acids; while these may be ingredients in a binder, the finished preparation must be classified under the more specific 3824.10 code.
Top exporters and importers of HS 382410 (the code used for core binders), 2025
In 2025, the largest exporter of HS 382410 (the code used for core 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).
