U.S. imports of other articles of stone or mineral substances (nesoi) (HS 681599) totaled $25.0M in July 2026, traded with 56 countries.
Importers of Other Articles of Stone or Mineral Substances (NESOI) paid $2.3M in duties in July 2026 — an effective duty rate of 13% on $18.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Other Articles of Stone or Mineral Substances (NESOI) imports of $25.0M in July 2026 ran 29% above the year-to-date monthly average of $19.3M.
Last updated: July 2026 dataA broad residual category, heading 681599 captures manufactured articles of stone or other mineral substances not covered by more specific headings in Chapter 68, including talc-steatite shapes, high-magnesia chemically bonded articles, and miscellaneous mineral composites. The US schedule includes four 10-digit lines: 6815990100 (general NESOI), 6815992000 (talc-steatite cut or sawed), 6815994110 (articles of stone with over 70% MgO, under 30% carbon, chemically bonded), and 6815994170 (remaining NESOI). Canada and South Korea lead US imports, with Germany, China, and Mexico also prominent. The heading's residual nature means classification here requires confirming that no more specific heading in Chapters 68 or 69 applies.

Talc-steatite articles (6815992000) are specifically cut, sawed, or otherwise shaped from natural steatite (soapstone), a dense talc-rich rock valued for its machinability and thermal resistance. They are used in electrical insulation, laboratory equipment, and high-temperature applications. Other mineral articles in this heading (6815990100 and 6815994170) cover a wider range of mineral compositions and manufacturing methods. The key classification factor for steatite is that the article is shaped from the natural mineral rather than formed from a processed mineral powder or composite.
The primary distinction between Chapter 68 and Chapter 69 is whether the article has been fired (calcined or sintered) to produce a ceramic product. Fired ceramic articles belong in Chapter 69, while non-fired or chemically bonded mineral articles generally remain in Chapter 68. If the manufacturing process involves kiln firing at temperatures that produce a ceramic bond, Chapter 69 should be considered first. When the process is ambiguous, requesting a binding ruling from CBP or consulting a licensed customs broker is the recommended approach.
