Last updated: August 2026 dataTaps, dies, and threading tools are essential precision cutting instruments used across aerospace, automotive, and general machining to produce internal and external threads. Under the US tariff schedule, 820740 is subdivided by alloy content: tools with cutting parts containing more than 0.2% chromium, molybdenum, or tungsten (or more than 0.1% vanadium) classify under 8207403000, while all other tapping and threading tools fall under 8207406000. Germany leads US imports in this heading, reflecting that country's long-standing strength in precision cutting tool manufacturing.

Importers should obtain certified mill test reports or material certifications from the manufacturer confirming the weight percentages of chromium, molybdenum, tungsten, and vanadium in the cutting part. These records should be retained as part of the entry documentation and made available to CBP upon request.
Combination tools that perform both drilling and threading functions present a classification challenge. CBP's general rule is to classify by the component that gives the article its essential character or, if that is indeterminate, under the heading that appears last in the tariff schedule. A binding ruling is advisable for novel combination tools to avoid misclassification penalties.
