HS Code 6814.90 – Mica; worked mica and articles of mica (excluding plates, sheets and strips) whether or not on a support of paper, paperboard or other materials
HS code 6814.90 is the 6-digit subheading for mica, worked mica and articles of mica (excluding plates, sheets and strips) whether or not on a support of paper, paperboard or other materials. It is used for mica tubes, mica gaskets, mica washers (cut from bulk), mica spacers and mica heating elements (components).
What HS 6814.90 covers
This code encompasses a broad range of worked mica and articles made from mica, excluding the plates, sheets, and strips specifically covered by 681410. These products leverage mica's unique properties, such as superior electrical insulation, high thermal stability, and chemical inertness, in various specialized applications. International trade involves components for electrical appliances, industrial furnaces, aerospace, and defense sectors. Importers and exporters are typically specialized manufacturers of electrical components, high-temperature equipment, and precision parts. The market is driven by the demand for durable, high-performance insulating and heat-resistant materials in niche industrial applications where other materials may fail, requiring custom-fabricated mica solutions for extreme conditions.

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).
