HS Code for Flint
Flint is classified under HS code 2517.10. This code is part of Chapter 25, which encompasses salt, sulfur, earths, and stone, as well as plastering materials, lime, and cement. Specifically, heading 2517 covers pebbles, gravel, and broken or crushed stone of a kind commonly used for concrete aggregates, road metalling, or railway ballast. Flint is a hard, sedimentary cryptocrystalline form of the mineral quartz, categorized as a variety of chert. When flint is presented as pebbles or in a crushed state for industrial or construction purposes, it is classified here. The classification applies whether the material is in its natural state or has been subjected to heat treatment to enhance its physical properties for use in construction or as a grinding medium. This heading also includes macadam of slag, dross, or similar industrial waste, but flint is specifically mentioned in the context of natural stone aggregates. The material must not be worked into specific shapes like blocks or slabs, as that would move the classification to Chapter 68. The granular or pebble-like form is essential for classification under 2517, as it reflects the intended use in bulk construction or industrial processing rather than ornamental masonry.
Products Included

- Unworked flint stones found in sedimentary deposits
Common Misclassification
Flint is sometimes misclassified under HS code 2506, which covers quartz and quartzite. While flint is a variety of quartz, heading 2517 is more specific when the material is used as an aggregate or ballast. Another potential error is classification under HS code 7103 if the flint is of a quality considered a semi-precious stone; however, industrial flint rarely meets these criteria. Additionally, flint used specifically as a "flint" for lighters is often classified under 3606.90 as a ferro-cerium alloy, which is a chemical product rather than the natural stone.
