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
