Feldspar; leucite, nepheline and nepheline syenite; fluorspar
5 declarable lines
Heading 2529 covers feldspar; leucite, nepheline and nepheline syenite; and fluorspar. It splits by material first, then fluorspar by calcium fluoride content and the leucite/nepheline group by whether the item is nepheline syenite or other. All listed lines carry a Free general (MFN) rate.
Products in this heading
- Feldspar powder for ceramic glazes
- Feldspar for glass batches
- Fluorspar lumps with 97% or less calcium fluoride
- Acid-grade fluorspar with more than 97% calcium fluoride
- Nepheline syenite for glassmaking
- Leucite mineral concentrate
- Nepheline mineral powder
How to choose the right subheading
- Identify the mineral first: feldspar, fluorspar, or the leucite and nepheline group.
- For fluorspar, measure calcium fluoride content; 97% or less and more than 97% go to different subheadings.
- For the leucite and nepheline group, decide whether the item is nepheline syenite or other.
- Do not use end use as the primary test; the listed lines turn on material and, for fluorspar, calcium fluoride content.
