Chapter 68 covers articles of stone, plaster, cement, asbestos, mica or similar materials, mainly including shaped articles of non-metallic mineral materials, such as stone slabs, millstones, sandpaper, slag wool, etc. These articles are usually processed and shaped for construction, grinding, insulation, filtration and other uses, but do not include ceramics, glass and natural stone itself. Heading 6815 covers non-metallic mineral articles not elsewhere specified, including millstones and similar articles of non-metallic minerals and other articles of non-metallic minerals. Among them, 681510 specifically refers to millstones and similar articles of non-metallic minerals, mainly used for grinding, polishing, cutting, etc., such as grinding wheels, oilstones, mounted points, etc., but attention should be paid to the distinction from ceramic millstones (6901) and natural stone millstones (6804). Code 681510 is a 6-digit subheading. The first 2 digits "68" represent Chapter 68: articles of stone, plaster, cement, asbestos, mica or similar materials. Digits 3-4 "15" represent heading 6815: articles of non-metallic minerals not elsewhere specified. Digits 5-6 "10" represent subheading 681510: millstones and similar articles of non-metallic minerals. This subheading is not further subdivided and covers all millstones and similar grinding tools made from non-metallic minerals (such as diamond, silicon carbide, corundum, etc.). This commodity is classified under 681510 rather than adjacent codes because its material is non-metallic mineral (such as synthetic diamond, silicon carbide, etc.) and its function is grinding. If it were a millstone of natural stone, it would be classified under 6804; if it were a ceramic millstone, under 6901; if it were a machine part, possibly under 8487. 681510 specifically targets millstones of non-metallic minerals, emphasizing material and use.

Explain the specific use of the millstone, such as grinding, polishing, cutting, etc., and the applicable objects (such as metal, glass).
⚠️ Failure to indicate the use, making it impossible to determine whether it belongs to millstones.
Brand
Declare the brand of the commodity; if no brand, fill in "none".
Declare the model of the commodity; if no model, fill in "none".
⚠️ Incomplete model filling or inconsistency with the actual goods.
Specifications and dimensions
Declare the external dimensions of the millstone, such as diameter, thickness, hole diameter, etc., usually in millimeters.
⚠️ Failure to provide dimensions, making it impossible to determine whether it belongs to millstones.

⚠️ Failure to indicate the processing method, which may affect classification.
Example： Product name: millstone of non-metallic minerals; Material: silicon carbide, resin binder; Use: for metal grinding; Brand: none; Model: SC-100; Specifications and dimensions: outer diameter 100mm, thickness 10mm, hole diameter 20mm; Processing method: pressing.
Common Mistakes：
Mistakenly classifying ceramic-bonded millstones under 6901; actually ceramic-bonded millstones are still classified under 681510.
Mistakenly classifying natural stone millstones under 681510; actually they should be classified under 6804.
Failure to declare material and use, resulting in customs being unable to determine classification.
🎯 Classification Logic
The core criteria for classification are: 1. The material must be non-metallic mineral (such as silicon carbide, corundum, diamond, etc.); 2. The use is grinding, polishing, etc.; 3. The shape is usually millstone, grinding wheel, etc. If the material is natural stone, it is classified under 6804; if ceramic, under 6901; if a machine part, under 8487. Attention should also be paid to the distinction from 6805 (abrasive cloth, sandpaper), which are coated abrasives. 6804 Millstones of natural stone: 6804 is millstones made of natural stone (such as granite, sandstone), while 681510 is made of non-metallic minerals (such as silicon carbide). 6901 Ceramic millstones: 6901 is ceramic millstones, but ceramic-bonded millstones are still classified under 681510; only wholly ceramic millstones are classified under 6901. 6805 Abrasive cloth, sandpaper: 6805 is coated abrasives with a backing of cloth, paper, etc., while 681510 is block-shaped millstones. 8487 Machine parts: 8487 is machine parts; if the millstone is a dedicated part for a specific machine, it may be classified under 8487, but general millstones are classified under 681510. Is the material a non-metallic mineral? Is the use grinding or polishing? Is it distinguished from ceramic millstones? Is it distinguished from natural stone millstones? Is it a dedicated machine part?
