Five dimensions to evaluate suppliers

Dimension	Key questions
Customization	Do they support custom length/color/width/slider/end? What is the MOQ?
Testing & certification	Do they run IPX rating tests, pressure tests, and provide reports? ISO certified?
Lead time	How long for samples? For production?
Responsiveness	Are inquiries and technical support prompt?
Pricing	Are there options that fit your budget without over-engineering?

International brand or Chinese manufacturer?

Choose international: when brand backing matters, volumes are very large, or origin requirements are strict.
Choose Chinese manufacturers: for flexible customization, small-to-mid batches, fast lead times, cost sensitivity, and technical support.
