Finding a product in China is easy — a search returns thousands of listings in minutes. Finding the factory that will actually make it to your specification, at the quoted price, and ship it on spec is the part that costs buyers money when it goes wrong. Yinhan Sourcing is a Shenzhen-based product sourcing service: we find and verify factories for your product, check samples against your specification, follow production, inspect every order to AQL 2.5, and deliver door-to-door. On our Pro Plan, the service fee is $0.

What a Product Sourcing Service Actually Does
A product sourcing service is the team on the ground between you and the factory. Instead of you searching listings, negotiating in a second language and hoping the shipment matches the photos, the sourcing service:
- Finds the right factory for the product — not just the cheapest listing, but a supplier whose production capability matches your specification, quantity and packaging requirements
- Verifies that supplier in person — business and production capability checked at the factory, not taken from a profile page
- Locks the specification before production — samples checked against what you asked for, so the bulk order is made to an approved sample
- Follows production and inspects the result — photo and video updates during the run, then a formal AQL 2.5 inspection before shipment
- Consolidates and ships — goods from one or several suppliers brought together in Shenzhen and delivered door-to-door, with customs help
That is the whole service on this page — the same end-to-end process described on our homepage, applied to the specific product you want to source.
Why Buyers Use a Sourcing Service — Instead of Ordering From a Listing
- A listing is not a verified supplier. Prices and photos online do not tell you whether the factory can make your product to spec, or whether it is a factory at all. We visit and verify suppliers in person before you commit — see our guide on how to verify a China sourcing agent.
- The cheapest quote is rarely the final cost. Materials, packaging and specification details get quietly downgraded when nobody is checking. Samples checked against your spec, production follow-up and an AQL 2.5 inspection are how that is caught while it can still be fixed.
- One contact instead of five. Factory, warehouse, inspection and shipping are coordinated for you from Shenzhen, instead of you managing each one separately across time zones.
How Our Product Sourcing Works — Step by Step
1. Send the product
Send a product link, photo or specification. Within 24 hours you receive a free supplier list and quotation you can compare against any price you already have. Low MOQ is welcome — many of our clients start with a small trial order before scaling.
2. Compare and choose a supplier
We streamline the supplier options and verify the factory in person — business and production capability — before you commit to one.
3. Approve the sample
Samples are checked against your specification, so production starts from an approved sample, not a listing photo.
4. Production, followed up
Your dedicated manager tracks production and sends real-time photo and video updates while your order is made, so a drift from the approved sample is caught mid-run, not at the end.
5. AQL 2.5 inspection before shipment
Sampled units are inspected to AQL 2.5 at the factory or at our Shenzhen warehouse — workmanship, specification, function, quantity, packaging and labelling — with a photo and video report before your balance is at risk. Full detail: Quality Control & Inspection in China.
6. Consolidation and door-to-door delivery
Goods from multiple suppliers are consolidated at our warehouse — free for 3 months on the Pro Plan, 1 month on Basic — then shipped door-to-door with customs help. Selling on Amazon? See Sourcing Agent for Amazon Sellers.
Sourcing From Shenzhen — Why Location Matters for Product Sourcing
Our Shenzhen base puts Huaqiangbei’s electronics markets, Pearl River Delta factories and the Yantian and Shekou ports within reach — which is why electronics and factory-direct products from the Delta are our home ground. For the city-level detail, see our Shenzhen Sourcing Agent page.
Product Sourcing Fees — Published, Not Quoted in Private
- Pro Plan — $0 service fee. We source from our verified suppliers; sourcing, production follow-up, AQL 2.5 inspection and 3 months free warehousing are included in the unit price you approve before production. The Pro Plan also includes our quality guarantee: free replacement or compensation if quality issues arise.
- Basic Plan — 5% of product value, minimum $100. You use your own suppliers; we conduct AQL 2.5 inspection at our warehouse and arrange door-to-door shipping. Includes 1 month free warehousing. The quality guarantee does not apply on Basic, because the suppliers are yours, not ours.
