START A SOURCING BRIEFTurnkey sourcing
What we run on the China side
Full-service sourcing. Not a catalog with a chat box. You do not need a buying office in Qingdao — that is the job.
01
Supplier selection and vetting
What we do
We research and shortlist factories that can actually make what you specified — capacity, certifications, export history, and a plant we can walk. Not a storefront on a marketplace.
You provide
Your specification, target cost, quantity, and any must-have requirements.
You get
A shortlist of vetted factories and a realistic quote with MOQ and lead time.
02
Sample and specification lock
What we do
We run samples and freeze materials, tolerances, packing, and marks in writing, so bulk production is measured against an agreed standard — not memory.
You provide
Sample approval, or comments to revise the sample.
You get
An approved sample and a written specification for bulk production.
03
Production follow-up and quality control
What we do
Production is managed on the ground, with in-line and pre-shipment inspection in China. If it fails, it is reworked on the floor — not discovered at your warehouse.
You provide
No action required — we keep you updated on progress.
You get
Inspection report and photos before the container is sealed.
04
Export preparation
What we do
We prepare export cartons, palletization, marks, commercial invoice, packing list, and the documentation EC INDUSTRY needs to clear and move the shipment.
You provide
Final shipping instructions and destination.
You get
Goods packed, documented, and handed over for the move.
