9017.10 - Drafting tables and machines, whether or not automatic:

Category 9017.10 specifically encompasses drafting tables and machines, including those that operate automatically. These instruments are designed for the precise creation of technical drawings, plans, and schematics. The key characteristic of this subheading is its focus on the apparatus used to physically lay out and execute the drawing process, whether manually operated or automated.

Unlike sibling category 9017.20, which covers other drawing and calculating instruments like pantographs or slide rules, 9017.10 is exclusively for the tables and the machines that operate upon them for drafting purposes. It is also distinct from 9017.30 (micrometers, calipers, and gauges) which are used for linear measurement, and 9017.80.00.00 which is a residual category for other instruments not elsewhere specified within Chapter 9017.

The subcategories within 9017.10, namely 9017.10.40.00 (Plotters) and 9017.10.80.00 (Other), further refine the classification based on the specific function and type of drafting machine. Plotters, a significant subset, are automated devices that precisely draw lines or points based on computer instructions. The "Other" subcategory captures any remaining drafting tables and machines that do not fall under the specific plotter classification.
