U.S. imports of rock drilling & earth boring tools with non-cermet working parts (base metal) (HS 820719) totaled $24.0M in April 2026, traded with 39 countries.
Importers of Rock Drilling & Earth Boring Tools with Non-Cermet Working Parts (Base Metal) paid $3.5M in duties in April 2026 — an effective duty rate of 16% on $21.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 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.
