Custom phone case sourcing FAQs

Can Kejie support a private-label launch?

Kejie describes private-label and customization options on its service page. Start with a published product reference, then confirm model coverage, branding, packaging and the sample route.

Do I need a new mold?

Logo, color and packaging changes may use an existing platform. Geometry or component changes can require additional development. Ask for separate setup and tooling costs.

What is the MOQ?

MOQ depends on the model, material, color, decoration and packaging. Request written quantities per variant; do not assume mixed models share one minimum.

How long does a custom project take?

Ask for milestones covering design review, sample preparation, approval, tooling if required and production. The schedule depends on the agreed configuration.

How do I assess a magnetic case?

Check the intended phone and accessory combination, magnet alignment and any claimed certification. A magnetic ring alone does not establish MagSafe or Qi2 certification.

What should I send for a quotation?

Send exact phone variants, a product reference, customization files, quantity by variant, packaging needs and launch timing. Use the RFQ checklist above.
