Importers of Rock Drilling & Earth Boring Tools with Non-Cermet Working Parts (Base Metal) paid $5.1M in duties in August 2026, an average duty rate of 12.68% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Rock Drilling & Earth Boring Tools with Non-Cermet Working Parts (Base Metal) imports of $40.3M in August 2026 ran 44% above the year-to-date monthly average of $28.0M.
Last updated: August 2026 dataPercussion and rotary rock drill bits, core bits, and reamers with base-metal working parts — excluding cermet — span a wide range of alloy specifications that drive classification across multiple 10-digit HTS lines under 820719. The US schedule distinguishes percussion bits (8207191030) from rotary bits (8207192030), and further subdivides by alloy content thresholds for chromium, molybdenum, tungsten, and vanadium, with additional lines for diamond-tipped rotary bits (8207196065) and catch-all NESOI provisions. Japan leads US imports under this heading, with China and Germany also significant sources.

Several 10-digit lines under 8207193030, 8207193060, and 8207193090 apply specifically to tools whose working parts contain more than 0.2% chromium, molybdenum, or tungsten, or more than 0.1% vanadium. These thresholds reflect the US tariff schedule's effort to distinguish high-alloy tool steels from standard base metal. Importers must verify certified mill test reports or material certifications to support the correct line classification.
Each product type must be classified and invoiced separately: percussion bits, rotary bits, and parts each have distinct 10-digit HTS lines under 820719. Commingled invoicing without line-item breakdowns can trigger CBP scrutiny. A licensed customs broker can help structure the entry to ensure each line item is correctly declared.
