Why being in Shenzhen matters
Factory clusters decide everything — materials markets, component vendors, tooling shops and the labor pool concentrate by region, and a team inside the cluster sources in hours what an outsider quotes in weeks. It also means audits and inspections are done by our own staff driving to the factory, not subcontracted to whoever is available. The routines our team runs are documented in our supplier verification guide and our factory audit guide.
How we are paid
By you — never by the factories. Our commission is published on our pricing page, the mechanics are explained in sourcing commissions explained, and every quote itemizes the factory price separately from our fee. That alignment is the product: one team whose income depends on your goods arriving right and your cost going down.
How can you check us before committing?
Read how the process works and our case studies, then test us with a trial order, a single audit or one inspection.

Who is behind Yinhan Sourcing?
Yinhan Sourcing is a team of Chinese and international staff working from one office in Shenzhen, the city that sits at the center of the Pearl River Delta manufacturing belt and a short drive from Yantian, one of the busiest container ports in the world. Being on the ground here is not a slogan; it is what makes factory visits, same-week inspections, and honest schedule checks possible.
The team is bilingual and structured around one principle: the buyer should be able to verify everything. Quotes name the factories. Reports come with photos. Payments are tied to passed inspections. The process page shows the sequence, and the client stories show what it produces.
If you are comparing agencies, the questions to ask anyone, including us, are collected in the agent vetting checklist. We are happy to be measured against that list.
Why does the office location matter so much?
A sourcing agent can work from anywhere; a sourcing partner cannot. Being in Shenzhen puts the team within same-day reach of the factories in Guangdong, the inspection labs, the consolidation warehouses, and the port terminals where your goods actually leave the country. When a production line needs eyes tomorrow morning, or a shipment needs a decision before the container closes, distance is the difference between a solved problem and a story about one. The contact page lists the office details and hours.

About the team: questions buyers ask
A Shenzhen-based team of bilingual sourcing managers, inspectors and logistics staff. How we are paid is on the commission page; what clients say is on testimonials with results in case studies.
Where are you actually based?
Shenzhen, China — one of the country\u2019s largest manufacturing hubs, within day-trip range of the Pearl River Delta factory belt. Being on the ground means same-day factory visits, in-Chinese chasing and inspections that happen before your balance moves, not after.
Who will handle my order?
A dedicated bilingual sourcing manager owns your file end to end, backed by on-site inspectors for audits and QC plus logistics staff for consolidation and export documents. You get one point of accountability and replies inside your business hours overlap.
What do you do in a typical week?
Verify licenses, benchmark RFQs across vetted lines, approve samples against written specs, walk production floors with photo check-ins, gate balances on AQL inspections and consolidate multi-supplier goods — the cadence is visible in how it works.
How are you paid — is there a hidden margin?
No. Commission of 5–8% is billed separately while factories invoice you directly at factory prices; pass-through costs arrive with original invoices. The structure, with the flat-fee brief from $149, is written on the commission page.
Which sellers do you work with?
Amazon FBA sellers needing compliance, prep and direct-to-FBA shipping; Shopify and DTC brands building private label; and first-time importers starting with small trial orders. Each path has its own playbook.
How can we meet before committing?
Through the contact page: a free video consultation, references in your category on request and sample inspection reports to review. Most relationships start with a trial brief or single inspection, then scale on evidence.
Can I visit your office in Shenzhen?
Yes — client visits are welcome by appointment, ideally timed with a factory audit or production milestone so the trip covers both. If travel is not practical, the same transparency comes through video walkthroughs, weekly photo reports and the documentation behind every quote.
What languages do you work in?
Chinese with factories and English with you — negotiation, contracts and chasing happen in Chinese while every report, quote and update arrives in clear English. Bilingual handling is exactly what removes the communication failures behind most sourcing disputes.
Do you work with buyers outside English-speaking markets?
Yes — current clients buy from the United States, United Kingdom, Germany and beyond, and documentation is prepared for EU, UK and US compliance regimes alike. Shipping is worldwide from Shenzhen with DDP options that simplify customs wherever you are.
