Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If individual selection boxes without full frame integration
Partial Jacquard assemblies classify as specified parts rather than complete mechanisms.
If for Jacquard-type selection in non-textile fabric production
Technical textile machinery uses different auxiliary classification.
If primarily valve assemblies for pneumatic selection
Pneumatic control valves classify as other valves when not integral.

Import Tips & Compliance
• Supply airflow and harness load specifications; vibration testing data helpful
• Pitfall: classifying frames separately from selection box; import as tested assembly
