Frequently Asked Questions

Key details regarding our sourcing process, custom engineering, quality audits, MOQs, and global shipping.

What OEM and ODM options are available?

We offer logo printing, custom enclosure colors, exclusive mold tooling, custom firmware pre-loading, and tailored multi-language educational packaging.

How do you enforce quality control?

Our inspectors perform on-site incoming material checks, in-process electronics testing, and pre-shipment AQL standard sampling before clearing goods for export.

What are your minimum order quantities (MOQ)?

MOQs depend on product complexity. Off-the-shelf component sourcing starts at 300 to 500 units, while custom injection-molded products typically start at 1,000 units.

How are international shipping and customs handled?

We handle export clearance in China and coordinate air freight, sea freight (FCL/LCL), or rail shipments directly to your destination port or fulfillment center.

How does product sourcing work?

Can you handle multiple suppliers for one kit?

What does custom development cover?

How are sample evaluations conducted?

We evaluate your technical requirements, screen verified manufacturers in our China network, negotiate target pricing, and manage sample testing before mass production.

Yes, we regularly coordinate component sourcing across multiple specialized plants (e.g., plastics, electronics, printed manuals), consolidating them into single retail-ready kits.

Our engineering covers full product design, 3D mechanical CAD, PCB layout, firmware programming, functional prototyping, and design-for-manufacturing (DFM) optimization.

We create prototype units, test mechanical tolerances and electrical functions in our facility, and express-ship verified samples for your team to test and approve.
