Five checks to run before you pay a deposit: the legal entity, the factory, the specification, the certification your market requires, and the payment terms.
Buying power tools from China is not the difficult part. Keeping the same supplier through the third container is. Most of the money lost in this trade goes before the first unit is built: a deposit sent to a company that does not own the factory, a specification never written down, or a test report covering a different model.
We make and export power tools from Shijiazhuang and sell to importers, wholesalers and private-label brands. The five checks below are the ones we expect a serious buyer to run on us.
A supplier comparison usually starts with the unit price. That is the last number to look at, because it follows from four decisions you have already made, whether you build a private-label brand or buy from a catalogue.
| What it is | What to establish before you compare prices |
|---|---|
| Tooling and moulds | Who owns the tooling, where the moulds are stored, and what happens to them if you stop ordering. If the supplier owns them, switching later means buying tooling twice. |
| The specification | A written sheet listing the parts that matter to a tolerance or by supplier. A model number is not a specification. |
| Compliance liability | Which standard applies, which report exists, and which model numbers it covers. The importer signs the declaration of conformity, not the supplier. |
Ask for the business licence and the company name in Chinese. Every mainland company has an 18-digit Unified Social Credit Code. Search that code or the Chinese name on the National Enterprise Credit Information Publicity System at gsxt.gov.cn.
The record shows the registered name, capital, scope and date of establishment. It also shows whether the company sits on the abnormal operations list, whether penalties are recorded, and whether it appears on the serious illegal and dishonest list.
Registered capital is a scale signal and nothing more.
Two things must line up before money moves. The legal name on the contract, the invoice, the packing list and the bank account has to be the same entity; a payment request to a personal account is the clearest fraud signal in this trade. The company must also hold export rights.
Many companies that describe themselves as manufacturers are trading companies with a catalogue. That is not automatically a problem: a trading company handles small orders and mixed containers that a single factory will not. The problem is paying factory-direct prices for trading-company service.
A factory walkthrough, arranged in advance. An unannounced video call is the strongest test, but it is not always possible. Plenty of genuine suppliers sell from a city office while the plant sits at another site, and the sales team is not on the line. Arrange a time instead, and ask to see six things on camera: the name on the gate sign; an unbroken three-minute walk down the line; the weekly production board; one machine of your choice started while you watch; the quality control station; and a phone in frame showing the current date. If a walkthrough cannot be arranged, send a third-party inspector to the address, which is stronger evidence in any case. What should end the process is a supplier who refuses every form of site verification, shows only a showroom, or sends last year’s footage.
Technical questions only the line can answer. Which press makes the housing. Who owns the mould. What the cycle time is. What tolerance is held on the gearbox bore. The people who run the line answer these immediately. A reseller comes back later with an answer from somebody else.
This is where power tools differ from general merchandise. Three answers separate a supplier that can build your product from one that can only sell you something from a catalogue.
Where the cells come from. For cordless tools, ask which cells are used, whether they are a named brand or an unbranded equivalent, what the protection board inside the pack does, and whether the pack is built in the same plant as the tool. Our guide to choosing a cordless tool battery covers the platform questions.
How the performance figures were measured. A torque figure without test conditions cannot be compared with anything. Ask at what voltage and load it was measured, which bit or socket was used, and whether it is peak or sustained. A number that arrives with its test conditions is usable. A number that arrives alone is marketing.
Endurance testing. Ask what duty-cycle test the model passes: how many cycles, at what load, against what pass criterion. An AQL inspection checks appearance, packing and function on the day of shipment, and says nothing about whether a switch survives two years of daily work. Our notes on power tool reliability testing set out what that data should contain.
Put the answers into a written specification sheet, and keep the sample you approved. Date it, sign it, have it sealed. That sealed sample is the reference for every inspection and every dispute after it.
Compliance is where a cheap supplier becomes an expensive one. Ask which standard the tool will be tested to, which report exists and which model numbers it covers, then check the claim against the rules of your market.
| Market | What applies | How the claim is checked |
|---|---|---|
| European Union and EEA | CE marking for machinery. Hand-held tool safety is tested to IEC/EN 62841, which replaced EN 60745 and EN 61029. The Machinery Regulation (EU) 2023/1230 applies from 20 January 2027, replacing Directive 2006/42/EC. | CE is a manufacturer declaration backed by a technical file, so no register of CE products exists. Ask for the declaration of conformity and the test reports, and check any notified body in the EU NANDO database, which confirms the body and not your product. |
| Germany | GS is voluntary, issued under ProdSG by a body authorised by ZLS, and normally includes an initial factory inspection and annual surveillance. | The record sits with the issuing body. Ask for the certificate number and the body name, then verify with that body. |
| United States and Canada | UL and ETL are legally equivalent listings from OSHA-recognised NRTLs, and both test to the same UL standards. UL 62841-1 has been the standard for new listings since 21 February 2018. | Search the file number in UL Product iQ for UL, or the Intertek directory for ETL. |
| Saudi Arabia | SABER and SASO requirements. | Check the certificate in the SABER system. |
| Several markets at once | A CB test certificate comes through the IECEE scheme. It is not a product mark or a market approval, it covers safety and not EMC, and national differences must be tested in the original programme. | Verify through IECEE. |
For cordless tools, add the battery. In the EU, Regulation (EU) 2023/1542 requires portable batteries to be removable and replaceable by the end user from 18 February 2027, and lithium cells travel with a UN 38.3 test summary.
A charger supplied separately follows its own route, usually the Low Voltage Directive in the EU. If your programme includes chargers and battery packs, keep them as separate line items in the compliance file. Our guide to power tool certifications covers the marks in more detail.
Payment structure is the last thing you control, and it decides what happens if everything else goes wrong.
None of these documents proves what buyers usually assume it proves.
| Document | It establishes | It does not establish |
|---|---|---|
| Business licence | That the company legally exists, and the scope it is registered for. | That it owns a factory, or makes your product. |
| Test report | That a named sample passed a named standard at a named laboratory. | That the units in your container are built the same way. |
| Declaration of conformity | That the manufacturer has declared conformity and holds a technical file. | That anyone independent has checked it. |
| Factory audit report | That a site existed and matched its description on the audit date. | That your order will be produced there. |
Send these in one written message, before anyone quotes a price.
A supplier that answers ten of these and explains the eleventh is normal. A reply that names no address, no standard and no numbers, and asks only for your target price, answers none of them.
| Signal | What to do |
|---|---|
| The bank account name differs from the licence, or payment is requested to a personal account | Do not transfer until the names match in writing. There is otherwise no route to recover the funds. |
| Refusal of every form of factory verification: a visit, a walkthrough, or a third-party inspection | Stop and re-verify. The claimed operation may not exist. |
| Certificate numbers the issuing body cannot confirm | The document may not be genuine, or may cover another product. |
| A price well below every other quote | Ask for the itemised cost breakdown. The build or the materials are usually different. |
| Vague capacity answers, or a catalogue of unrelated products | Ask which factory will make the order, by name. |
| Pressure to skip the sample or the inspection | Slow the process down. The margin depends on you not checking. |
Finish the process with a recorded decision rather than a folder of screenshots. Approve when identity, payment, capability and compliance evidence all match, with no unresolved red flag. Conditionally approve when the supplier is credible but one risk needs a control, and place a smaller trial order or tighten the inspection. Reject when the payment name does not match, documents fail verification, or reasonable checks are refused.
We are one of the suppliers this article tells you to check, so the list applies to us. Our own factory and our sales and export office are at separate sites, so a walkthrough has to be arranged rather than taken on the spot. At first contact we will put in front of you the business licence and credit code, the specification sheet for the model you are looking at, test reports carrying the standard numbers and the model numbers they cover, a paid sample, and acceptance of an independent pre-shipment inspection before the balance. If you want the line itself verified, we will book a video walkthrough with the plant running your order, or invite a third-party inspector to the address.
Browse the product range, including cordless, corded and garden power tools, or send us the model and the market and we will tell you which standard it has to meet.
This article is intended as a general sourcing reference. Certification requirements differ by market and by product; confirm the standards and the paperwork on the current order before shipping.
