Selling on Amazon from products made in China means your supplier, your inspection and your shipment all have to be right at the same time — a defect or a labelling mistake does not just cost a refund, it can cost the listing. Yinhan Sourcing is a Shenzhen-based sourcing agent for Amazon sellers: we find and verify factories, inspect every order to AQL 2.5, handle FBA prep and labelling, consolidate your goods in Shenzhen, and deliver door-to-door to Amazon FBA warehouses. On our Pro Plan, the service fee is $0.

Why Amazon Sellers Use a Sourcing Agent in China — Instead of Ordering Direct
Ordering direct from a marketplace listing leaves the three risks that hurt Amazon sellers most with nobody on the ground to catch them:
- The wrong factory. A listing is not a verified supplier. We visit factories in person, verify the business and production capability, and check samples against your specification before you commit — see Supplier Verification & Factory Audit and our guide on how to verify a China sourcing agent.
- Defects found too late. A factory’s own “QC passed” message is not an inspection. We inspect sampled units to AQL 2.5 before shipment — workmanship, specification, function, quantity, packaging and labelling — and send photos, video and defect counts while your balance is still in your hands. Full detail: Quality Control & Inspection in China.
- An FBA shipment that arrives wrong. Retail packaging, barcodes, carton marks and FBA labelling requirements are checked in the pre-shipment inspection, goods from multiple suppliers are consolidated at our Shenzhen warehouse, and the shipment is arranged door-to-door to the FBA warehouse — instead of you coordinating factories, a warehouse and a forwarder across three time zones.
What We Do for Amazon Sellers — End to End
1. Product & supplier sourcing
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. Samples & verification
Samples are checked against your specification and the factory is verified in person before production, so the bulk order starts from an approved sample, not a listing photo.
3. Production follow-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.
4. AQL 2.5 inspection, FBA prep & labelling
Before shipment, sampled units are inspected to AQL 2.5 at the factory or at our Shenzhen warehouse — including packaging & labelling: retail packaging, barcodes, carton marks and, for Amazon sellers, FBA labelling requirements. Problems found here are fixed before the goods leave China.
5. Consolidation, warehousing & FBA 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, including delivery to Amazon FBA warehouses. Our Shenzhen base puts Huaqiangbei’s electronics markets, Pearl River Delta factories and the Yantian and Shekou ports within reach — see our Shenzhen Sourcing Agent page.
Fees for Amazon Sellers — Published, Not Quoted in Private
- Pro Plan — $0 service fee. We source from our verified suppliers; sourcing, production follow-up, AQL 2.5 inspection, FBA prep & labelling 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.

Frequently Asked Questions
Can you deliver directly to Amazon FBA warehouses?
Yes. We consolidate your goods in Shenzhen and arrange door-to-door shipping with customs help — including delivery to Amazon FBA warehouses.

Yes — sourcing, prep and labelling for FBA are part of the service. Packaging & labelling are checked in the pre-shipment inspection: retail packaging, barcodes, carton marks and FBA labelling requirements.

Included. Both plans include AQL 2.5 inspection with a photo and video report — the Pro Plan at a $0 service fee (with a quality guarantee), and the Basic Plan at 5% of product value with a $100 minimum (quality guarantee does not apply, as suppliers are your own).

Yes — low MOQ is welcome. Many of our clients are Amazon sellers and eCommerce businesses starting with a small trial order before scaling up.
