HS Code 6815.99 – Stone articles and articles of other mineral substances; n.e.c. or included in heading no. 6815
HS code 6815.99 is the 6-digit subheading for stone articles and articles of other mineral substances, n.e.c. or included in heading no. 6815. It is used for mineral wool insulation boards, graphite electrodes, mica sheets, vermiculite boards and expanded perlite products.
What HS 6815.99 covers
This is a residual HS code for articles of stone or other mineral substances not specified elsewhere in heading 6815, and importantly, not containing asbestos. This broad category covers an incredibly diverse range of products, from specialized industrial components to niche consumer goods, all derived from various mineral sources. Examples include certain types of insulation, friction materials, electrical insulators, or even decorative items, provided they are not covered by more specific headings. Importers and exporters vary widely depending on the specific product within this catch-all category, reflecting global industrial demand for specialized mineral-based solutions. Key aspects include the unique physical and chemical properties of the mineral used, which dictate the article's application, and the often specialized manufacturing processes involved in their production.

Codes often confused with 6815.99
Common mistake. Can be confused with 6806 (slag wool, mineral wool) if the articles are primarily insulation, or 6903 (other refractory ceramic goods) if the mineral substance is ceramic-like but not fired.
Top exporters and importers of HS code 681599, 2025
In 2025, the largest exporter of HS code 681599 in UN Comtrade data was Germany, with 16% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports. The United Arab Emirates did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 91% of its imports here ($85M, CEPII BACI), so it may also belong among the top importers.

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).
