U.S. imports of Other Nonmetallic Mineral Mining & Quarrying (NAICS 212390) totaled $283.3M in August 2026, imported from 86 countries.
Importers of Other Nonmetallic Mineral Mining & Quarrying paid $5.9M in duties in August 2026, an average duty rate of 2.19% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Other Nonmetallic Mineral Mining & Quarrying imports of $283.3M in August 2026 ran 22% above the year-to-date monthly average of $231.3M.
Last updated: August 2026 dataExtraction operations for nonmetallic minerals not elsewhere classified — including potash, borate, sulfur, and barite — are captured at this NAICS 6-digit level, representing the most granular domestic production classification for miscellaneous industrial minerals. Barite, for example, is a critical input for oil and gas drilling fluids, while borates serve glass fiber and detergent manufacturing. Import classification for these minerals diverges significantly by mineral type, so trade professionals should map each commodity to its specific HTS chapter rather than relying on the NAICS grouping.

Barite is the primary weighting agent in drilling muds used in oil and gas well completion. Supply disruptions or quality inconsistencies — barite must meet API specifications for specific gravity — can directly affect drilling operations, making origin diversification and grade certification key procurement considerations.
Because this NAICS code aggregates many chemically distinct minerals, each must be classified individually under HTS Chapter 25 (mineral substances) or Chapter 26 (ores and slag) based on its chemical composition, processing state, and intended use. A licensed customs broker or CBP binding ruling is advisable for novel or multi-component mineral imports.
