Import Tips

Provide gear ratio calculations and CAD drawings showing multi-stage planetary configuration to distinguish from simple gear sets

Label assemblies clearly as 'complete gearing units' to avoid breakdown into individual components under different subheadings

Comply with RoHS directives for electronics-integrated gearboxes common in automation
