Screen Protector Sourcing Questions

The details importers, distributors and private-label brands ask before their first order.

What is your MOQ?
For custom OEM/ODM phone screen protectors, MOQ is 3,000 pcs per model — free brand design included, just provide your logo. Stock (non-customized) films start from 100 pcs. Tell us your models and we’ll confirm the exact MOQ.
What are your lead times?
Samples ship in 3–5 days. Mass production is typically 7–15 days after sample approval and payment are confirmed. Cutting machines usually ship within 3–7 days.
Can I get samples before ordering?
Yes. Existing samples are free (you cover shipping). Custom samples with your logo or packaging are charged at a small fee that is usually credited back against your bulk order.
Do you offer OEM and ODM?
Both. OEM: your logo and packaging on our proven products. ODM: new models, sizes and finishes developed to your spec, with engineering, tooling and sampling done in-house. Share your requirements through the Contact page and our engineering team will confirm feasibility.
What certifications can you provide?
The factory holds ISO 9001, ISO 14001 and BSCI. Products can be supplied with SGS, RoHS and CE test reports so you can clear customs and meet marketplace requirements.
How is quality controlled?
Production runs across 15 lines with RoHS testing and 100% visual inspection before auto-bagging. Every batch is checked against your approved sample before shipment.
Which payment terms and shipping do you support?
We support T/T and other payment terms confirmed directly with our sales team. We ship worldwide by express, air and sea, and can work with your forwarder. Orders can arrive labeled with the compliance documents you need at customs.
Is there a warranty on defects?
Yes. Verified manufacturing defects are covered — we replace affected units or credit them on your next order. Share photos or a defect rate and our sales team will resolve it directly.
