HS Code 25.29 – Feldspar; leucite; nepheline and nepheline syenite; fluorspar

HS code 2529 is a 4-digit heading in the Harmonized System that covers: Feldspar; leucite; nepheline and nepheline syenite; fluorspar. Heading 2529 encompasses several crucial industrial minerals: feldspar, leucite, nepheline, nepheline syenite, and fluorspar. These materials are fundamental raw inputs for a wide range of manufacturing processes. Feldspar, a group of aluminosilicate minerals, is extensively used in the ceramics and glass industries as a fluxing agent, providing alumina and alkalis. Leucite, nepheline, and nepheline syenite are similar feldspathoid minerals, also valued for their alkali and alumina content in glass and ceramic production. Fluorspar, the mineral form of calcium fluoride, is indispensable in metallurgy (especially steel and aluminum production), the chemical industry (for producing hydrofluoric acid), and in the manufacture of enamels and optical lenses. The classification focuses on these minerals in their natural state, typically in bulk, crushed, or ground forms. Accurate classification under 2529 is critical for determining correct import duties, adhering to any specific mineral resource regulations, and ensuring compliance with trade agreements. These minerals represent foundational components of modern industrial economies, reflecting their historical and ongoing significance in global trade. This heading aligns with Chapter 25, "Salt; sulphur; earths and stone; plastering materials, lime and cement," by focusing on naturally occurring, non-metallic mineral substances that are unprocessed or minimally processed.

Traders often misclassify these minerals if they are part of a mixture or have undergone significant processing. If a product is a mixture of minerals not specifically named in 2529, it might fall under 2530.90 (Other mineral substances not elsewhere specified or included). Fluorspar, if chemically processed into synthetic fluorides, should be classified under Chapter 28, for instance, 2826.19 (Other fluorides). Similarly, if feldspar is incorporated into a manufactured ceramic product, it would move to Chapter 69, such as 6901.00 (Bricks, blocks, tiles and other ceramic goods of siliceous fossil meals). The key is the natural, unprocessed, or minimally processed state of the named minerals.

In 2025, the top exporters of HS code 2529 in UN Comtrade data were Türkiye ($275M, 16% of world exports), Mongolia (about $252M) and South Africa ($226M). World exports came to about $1.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 2529 in UN Comtrade data were China ($323M, 16% of world imports), the United States ($289M) and Italy ($280M). World imports came to about $2.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 2529 is a 4-digit heading under Chapter 25 of the Harmonized System. The first 2 digits (25) identify the chapter, and digits 3-4 (29) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
