Product classification
HS code for Mica plates: 6814.10
Mica, plates, sheets and strips of agglomerated or reconstituted mica, whether or not on a support of paper, paperboard or other materials.
Classification of mica plates under HS 6814.10
Mica plates are classified under HS code 6814.10 because they consist of agglomerated or reconstituted mica. This classification is governed by the composition of the material rather than its end-use. According to the Explanatory Notes to the Harmonized System, heading 6814 covers worked mica and articles of mica. Subheading 6814.10 specifically targets plates, sheets, and strips made from mica flakes or powder that have been bonded together using various binders such as resins, glue, or shellac. These products are often reinforced with a support material like paper or fabric to improve mechanical strength. The classification is appropriate because the manufacturing process transforms raw mica into a standardized industrial product. This distinguishes it from natural mica sheets, which are simply split from the mineral. The technical requirement for 6814.10 is that the mica must be reconstituted; if the plate were made of a single piece of natural mica, it would fall elsewhere. This code is essential for manufacturers in the electrical insulation industry, as these plates are primarily used for their dielectric properties in motors, transformers, and heating elements.

Codes often confused with 6814.10
Common mistake. A frequent error is classifying these products under HS code 2525, which is reserved for natural mica and mica unworked or merely split into sheets. The distinction lies in the "worked" nature of 6814.10; once mica is ground and reconstituted with a binder, it leaves Chapter 25. Another common mistake is using HS code 8546 for electrical insulators. While mica plates are used as insulation, 8546 is for insulators made of any material that are specifically shaped or fitted with attachments for electrical purposes. If the mica plate is a simple rectangular sheet without specialized fittings, it remains in 6814.10.
Top exporters and importers of HS 681410 (the code used for mica plates), 2025
In 2025, the largest exporter of HS 681410 (the code used for mica plates) in UN Comtrade data was China, with 48% of world exports; the largest importer in UN Comtrade data was Germany, with 16% of world imports.

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).
