U.S. imports of Mining & Oil and Gas Field Machinery (NAICS 333120) totaled $2.3B in August 2026, imported from 101 countries.
Importers of Mining & Oil and Gas Field Machinery paid $399.6M in duties in August 2026, an average duty rate of 17.30% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataDrilling rigs, longwall mining systems, and oilfield wellhead equipment serve the extractive industries and represent some of the highest per-unit-value machinery imports in US trade. Classification within HTS Chapter 84 is function-driven: equipment designed specifically for boring or sinking shafts is distinguished from general-purpose lifting or pumping machinery, and the distinction carries real duty consequences. Section 301 tariffs have affected Chinese-origin mining and oilfield equipment, while domestic content requirements in certain federal energy leases add a procurement dimension beyond customs compliance. Lead times for specialized equipment and the technical complexity of spare-parts classification make advance customs planning essential.

Spare parts for mining machinery are generally classified by their own essential character rather than by the machine they serve, unless a specific HTS provision covers parts of a particular machine type. This means a hydraulic cylinder for a mining excavator may classify differently than the excavator itself. Importers managing large parts inventories should conduct a dedicated classification review to avoid systematic misclassification.
Certain federal contracts and lease terms include Buy American or domestic content preferences that can restrict or complicate the use of foreign-manufactured drilling or production equipment. While these requirements are separate from customs law, they interact with import decisions: importers should verify contract terms before committing to foreign-sourced capital equipment for federally regulated projects.
