Product classification
HS code for Mica sheets: 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 sheets under HS 6814.10
Mica sheets made of agglomerated or reconstituted mica are classified under HS code 6814.10. This classification is part of Chapter 68, which deals with articles of mineral materials. Heading 6814 specifically covers worked mica and articles of mica. The sub-heading 6814.10 is dedicated to plates, sheets, and strips of agglomerated or reconstituted mica, whether or not they are on a support of paper, paperboard, or other materials. These products, often referred to as micanite or mica paper, are produced by binding small mica splittings or reconstituted mica pulp with resins or other binders under heat and pressure. This process creates large, uniform sheets that are not available in nature. These sheets are valued for their thermal and electrical insulation properties. The presence of a support material, such as glass fiber or paper, does not change the classification, as the mica provides the essential character of the product for its intended industrial use.

Codes often confused with 6814.10
Common mistake. Mica sheets are frequently misclassified under HS code 2525.10, which is for natural mica splittings. The distinction lies in the manufacturing process; 6814.10 is for sheets made from smaller pieces bonded together. They are also sometimes confused with 8547.90 (insulating fittings), but 6814.10 is the more specific heading for the material in sheet form before it is shaped into a specific fitting.

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).
