A dual-function implement is classified according to its principal use or, if that cannot be determined, by the component that gives it its essential character. If the tool is genuinely designed equally for both functions, it may fall under the residual subheading 820190 covering agricultural handtools not elsewhere specified. A binding ruling from CBP is advisable for combination tools where the primary function is ambiguous.

Many tariff lines under heading 8201 originating in China are subject to Section 301 measures. The measure attaches at the 10-digit HTS level and by country of origin, so importers should verify the specific line for each tool type rather than assuming uniform treatment across the heading.
