Import Tips
• Include historical/technical literature proving mechanical calculation function to distinguish from novelties
• Declare cursor and scale materials separately if over certain value thresholds trigger additional metallurgical declarations
• Avoid misdeclaration as 'office supplies' which would shift to Chapter 96; emphasize engineering precision scales
