HS Code 68.14 – Mica; worked, articles of, including agglomerated or reconstituted mica; whether or not on a support of paper, paperboard or other materials

HS code 6814 is a 4-digit heading in the Harmonized System that covers: Mica; worked, articles of, including agglomerated or reconstituted mica; whether or not on a support of paper, paperboard or other materials. Heading 6814 covers worked mica and articles made of mica, including agglomerated or reconstituted mica, whether or not on a support of paper, paperboard, or other materials. Mica, a naturally occurring mineral, is prized for its exceptional electrical and thermal insulating properties, as well as its flexibility and transparency. This classification is vital for industries requiring high-performance insulation and dielectric materials, such as electronics, electrical engineering, aerospace, and high-temperature applications. The scope of this heading is broad, encompassing various forms of processed mica, from sheets and plates to washers and tubes, as well as products made from mica splittings or ground mica pressed into a board (agglomerated or reconstituted mica). The inclusion of 'whether or not on a support' is crucial, indicating that mica products combined with other materials like paper or glass fiber for added strength or specific functionality still fall under this heading, provided mica remains the essential character. For trade compliance, understanding the level of 'working' is key to differentiating these products from raw mica (classified under 2525). Proper classification ensures accurate tariff assessment, adherence to specific industry standards, and smooth integration into global supply chains. This heading is a specialized component of Chapter 68, focusing on a unique mineral with specific industrial applications.

Mica sheets for electrical insulation, mica plates for heating elements, mica washers, mica insulation tubes, mica capacitors (unmounted dielectric components), mica heating element supports, mica gaskets, mica tapes for cable insulation, mica paper for high-voltage applications, worked mica powder, worked mica flakes, mica splittings, reconstituted mica boards, mica furnace linings, mica lamp shades (components), mica windows for high-temperature equipment, mica-glass composite sheets, mica-reinforced paper, flexible mica laminates, heat-resistant mica covers, mica spacers, mica segments for commutators, mica blocks, mica insulation sleeves, mica barrier plates.

A common error is confusing worked mica articles with raw mica (heading 2525). The distinction lies in the 'worked' nature, where the mica has been processed beyond basic cleaning or grinding. Another mistake is classifying finished electrical components (e.g., complete capacitors, heading 8532) that *contain* mica, rather than the mica article itself. Heading 6814 is for the mica article, where mica imparts the essential character, not the final device. Similarly, mica-based pigments would fall under Chapter 32.

In 2025, the top exporters of HS code 6814 in UN Comtrade data were China ($207M, 42% of world exports), Germany ($55M) and Austria ($37M). World exports came to about $498M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 6814 in UN Comtrade data were Saudi Arabia ($109M, 19% of world imports), Germany ($73M) and the United States ($50M). World imports came to about $583M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 6814 is a 4-digit heading under Chapter 68 of the Harmonized System. The first 2 digits (68) identify the chapter, and digits 3-4 (14) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
