How to Choose a Reliable Supplier in China

Why supplier selection carries more risk than price

A 6% price difference on a container is a small number. A rejected container is not: you pay for the goods, the freight, the inspection, the return or the rework, and you lose the selling season you were buying for. On electrical goods there is a further risk, because a product that fails the destination market’s safety requirements cannot be sold at all.

This is why the steps below are front-loaded. Most of the cost of a bad supplier is decided before the first order is placed, not after.

Step 1: Write the specification before you contact anyone

A specification is not a wish list. It is the document both sides will use to decide whether the goods are acceptable, so it needs to be specific enough to be argued about. At minimum it should cover:

• Material and finish, with a reference sample or a colour code rather than a description.
• Dimensions with tolerances, not dimensions alone.
• The standards the product must meet in the destination market.
• Packaging: retail box or bulk, artwork responsibility, and how the carton is marked.
• Order quantity for the first order and the expected annual volume.
• Who owns the tooling, and what happens to it if you change supplier.

Suppliers quote what they are given. If the specification is vague, the quotation is vague, and every supplier appears equally capable because none of them has been asked a precise question. A written specification is also the fastest way to find out which suppliers actually read it.

Step 2: Find candidates, then screen them by behaviour

Most buyers start on the well-known B2B platforms, and that is a reasonable starting point. The screening, however, should not stop at the platform profile. Platform tenure, transaction history and response quality are all useful signals, and a supplier who has traded on the same account for several years has more to lose than one who registered last month.

Trade data is the other useful screen. The UN Comtrade database publishes import and export statistics by product code and partner country, which lets you see whether the product category you are buying genuinely flows from China to your market at the volumes being discussed. It will not identify a specific factory, but it will tell you whether the numbers you have been quoted are plausible.

Step 3: Verify the company, not the brochure

Every legally registered company in mainland China has a unified social credit code and a public record showing its registered capital, establishment date, registered address, business scope and any administrative penalties. Checking that record takes a few minutes and answers basic questions the brochure cannot: does the company exist, is it old enough to be stable, and does its registered business scope actually include manufacturing the product you are buying?

The last point matters more than it sounds. A large number of “manufacturers” on B2B platforms are trading companies. That is not automatically a problem – a good trading company can be a better partner than a weak factory – but it changes the questions you need to ask about who controls tooling, quality and delivery.

The other check that separates real factories from intermediaries is a live factory audit, either by your own visit or by a third-party inspection company. Any supplier who refuses an audit, or who will only allow a visit to a meeting room, has answered the question.

Step 4: Ask the questions that reveal how the factory works

Price and lead time are the two easiest answers to give and the two least informative. The questions below are harder to answer well, and the quality of the answers predicts the order more reliably than the quotation does:

• What is the minimum order quantity, and what drives it? A MOQ that maps to a real constraint – a mould, a panel size, a component spool – is a real MOQ. A MOQ that changes as soon as you push is a negotiating position.
• Which parts of the product do you make in-house, and which are subcontracted? This is where lead-time risk and quality risk live.
• What is the sample lead time and the production lead time separately? A single combined number hides where the delay will appear.
• What are the payment terms, and what triggers each stage? Terms tied to inspection milestones are worth more than terms that are simply lower.
• Who owns the tooling and the artwork files? Ask before the first order, not after.
• How do you handle a batch that fails inspection? The answer should be a process, not a promise.

How a supplier answers is more revealing than what they answer. References from existing buyers are the same kind of signal: a supplier with several long-standing export customers can usually put you in touch with one, and the way they respond to that request tells you how they expect the relationship to work. How we run this stage on our own orders is described on the quality control page.

Step 5: Agree the trade terms before negotiating the price

A quoted price means nothing until the delivery term is fixed, because the same ex-works figure and delivered figure can differ by more than the price difference you were trying to negotiate. The International Chamber of Commerce publishes the Incoterms rules that define who arranges and pays for carriage, insurance, export clearance and import clearance under each three-letter term, and which point the risk transfers to the buyer.

Two practical points are worth stating. First, compare suppliers on the same Incoterm, or the comparison is meaningless. Second, if you are new to importing, EXW puts almost all the logistics burden on you, while terms such as CIF shift the freight arrangement to the supplier but also hand them the choice of carrier and routing.

Step 6: Inspect before shipment, then scale

The cheapest risk reduction in importing is a pre-shipment inspection carried out by an independent third party against the specification you wrote in step 1. The inspection happens at the factory, before the goods are packed into a container, which is the last moment when a problem can still be fixed without shipping it around the world first.

Scale only after the first order has been delivered and checked. A supplier who performed well on 200 units has demonstrated capability, not capacity – the second order is where tooling wear, subcontracting and rushed production usually appear.

The red flags that predict a bad order

• A price well below the rest of the market, with no explanation of what was removed to get there.
• Unwillingness to put the specification, tolerances and inspection standard in writing.
• Certificates that name a different model, a different factory or an expired standard.
• A refusal to allow a third-party inspection or a factory visit.
• Payment requested to a personal account rather than a company account.
• Answers that arrive instantly and perfectly, for questions that require the factory to check something.

How this applies to a two-division supplier

For buyers furnishing a property, the sourcing question is rarely about a single product. A hotel room needs wall switches, sockets and a fitted furniture package, and each of those has its own certification and inspection requirements. Consolidating them with one supplier reduces the number of audits and inspections you have to commission, but it raises the bar on verification, because a single weak product line now affects the whole shipment.

The specification-first process on the OEM and ODM page describes how that works in practice, and the product pages show the ranges it applies to.
