U.S. imports of non-numerically controlled knee-type milling machines for metal removal (HS 845959) totaled $473K in April 2026, traded with 7 countries.
Importers of Non-Numerically Controlled Knee-Type Milling Machines for Metal Removal paid $60K in duties in April 2026 — an effective duty rate of 21% on $285K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataManually controlled knee-type milling machines remain a staple of job shops, vocational training facilities, and maintenance departments, with Taiwan the dominant US supplier under this heading. The US schedule splits entries by condition and value: used (8459590010), new units under $3,025 (8459590020), and new units at $3,025 and over (8459590030). Canada and China are secondary sources, and imports from China carry Section 301 tariff exposure. Buyers evaluating total landed cost should factor in the value threshold carefully, as a machine invoiced just above $3,025 shifts to a different tariff line than one invoiced just below.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Each machine must be classified individually based on its own transaction value. Units under $3,025 enter under 8459590020 and units at $3,025 or over enter under 8459590030. The commercial invoice should itemize each machine separately with its individual price to support the split classification. Grouping machines at a blended average price is not acceptable and can trigger a CBP inquiry.
Machines originating in China are subject to Section 301 tariffs in addition to the standard MFN duty rate. Machines from Taiwan are not subject to Section 301 measures, making Taiwan-origin equipment a common alternative for buyers seeking to reduce additional duty costs. Importers should verify country of origin carefully, particularly for machines assembled in one country from components sourced in another.
