A sourcing trip to China is expensive, exhausting and easy to waste. The importers who get real value from it treat it as an audit, not a shopping trip. They arrive with defined questions, they know what to look at on the shop floor before the salesperson starts talking, and they leave with evidence they can compare rather than a bag of brochures.
This playbook is for the buyer who is about to fly into Guangzhou, Shanghai or Yiwu and wants to come home with a shortlist they can trust. It is written from the supplier side of that table, which means it also tells you what a serious factory genuinely expects a serious visitor to ask.
A trip without a question produces photographs and no decisions. Before you book anything, write down the one or two things this trip must answer — for example, "Which of these three suppliers can hold a WRAS-approved thermostatic valve in volume at a stable price?" Then build everything around that.
Prepare a supplier dossier: company background, plant size, what they claim to make in-house, markets served, and the approvals they advertise. Assemble a specification sheet for the product you actually buy, plus a physical sample and a target price band. Bring your own scorecard (more on that below). And keep the itinerary realistic — two, at most three factories a day. A rushed visit tells you less than a thorough one.
Walk the process, not the showroom. For any manufacturing plant, ask to see the full route from incoming material to packed carton, and watch for these checkpoints:
Salespeople answer questions about features. Engineers answer questions about process. Try to get the technical person in the room and ask:
What is your monthly capacity for this product, and how much is currently committed?
Which steps do you outsource, and to whom — especially castings, plating and cartridges?
Where does your cartridge or valve core come from, and can you second-source it?
What is your lead-free and dezincification-resistant material capability — can you supply DZR brass to EN 12164/12165?
Which approvals do you currently hold, for which models, and in which markets — WRAS, NSF/ANSI 61 and 372, EN 817, EN 1111/1287, CE/UKCA?
How do you control alloy and plating quality batch by batch?
What is your on-time delivery record, and how do you measure it?
A supplier who answers these with documents and specifics is worth a second visit. One who deflects to price is telling you where their centre of gravity is.
Distrust any approval you cannot trace. On a certificate, check four things: the **scope** (does it actually cover the model you are buying?), the **issuing laboratory** (is it a recognised body?), the **model listing** (is your article number named?), and **validity** (is it current, not expired?). The same applies to management-system certificates such as ISO 9001, social-compliance audits such as BSCI or Sedex, and any test report. A scanned PDF from an unknown source is not evidence.
Score every visit the same day, while memory is fresh, using a weighted sheet: quality and process control 30 per cent, compliance and traceability 20 per cent, capacity and lead time 20 per cent, price 15 per cent, communication and responsiveness 10 per cent, and flexibility or custom capability 5 per cent. Weighted scoring stops a persuasive sales pitch from outranking a factory that simply runs a tighter process. Standard sampling theory helps you plan inspections later: **ISO 2859-1** (equivalent to **ANSI/ASQ Z1.4**) gives the attribute sampling plans that underpin most pre-shipment inspections.
Fairs compress weeks of visits into days, but only if you work them deliberately. The Canton Fair and Kitchen & Bath China (Shanghai) are the two most relevant for sanitary ware. Map booth numbers before you go and route by priority. At each booth, skip the brochure and collect answers: photograph the name card next to the booth sign, note the model numbers on display, and ask what is actually in production versus what is a concept. Ask to visit the factory of any supplier that impresses you — many will extend the invitation, and that is the real test.
Send a written summary to each shortlisted supplier within a week, restating your spec and asking them to confirm deviations. Order samples and have at least one tested by an independent third party (SGS, Bureau Veritas or TÜV) against your market's standard. Then structure the commercial relationship properly: agree **Incoterms 2020** terms (FOB, CIF or EXW), payment schedule, inspection rights, and the AQL level for pre-shipment checks. A trial order with a documented inspection is the cheapest insurance you will ever buy.
