Xi'an is where I am based, so this guide is about my home ground. Shaanxi is not a consumer goods province like Guangdong or Zhejiang. It is an industrial one. Xi'an makes heavy trucks, electric motors, transformers and high-voltage equipment, aerospace and precision parts, and a lot of power and industrial electrical equipment. Baoji, two hours west, is known as China's titanium city and makes oilfield and drilling equipment. Buyers usually come here for heavier, more technical products, where a wrong supplier is expensive.
This guide covers the main industries, what to check for each, and how a local visit works when the factory is close to me.
What Xi'an and Baoji make
Heavy trucks and truck parts. Shaanxi Automobile makes Shacman trucks in Xi'an, with a supplier base of axle, cab and parts makers around it, and many exporters of new trucks and parts.
Electric motors and electrical equipment. Large and medium motors, explosion-proof motors, transformers, switchgear and power equipment. This is my own industry.
Titanium. Baoji has a large concentration of titanium mills, processors and traders making bar, plate, tube, wire, forgings and fasteners.
Oilfield equipment. Drilling rigs, drill pipe, pumps and wellhead equipment around Baoji.
Precision machining and aerospace-related parts. Machining shops with aerospace experience serve industrial buyers too.
The checks that apply to every supplier here
Ask for the registered name and unified social credit code. Check the business scope, the registered address against the factory, the social insurance headcount, and court records. In Xi'an, many sales companies have offices in the high-tech zone and production in industrial parks outside the city or in other provinces, so confirm where your product is actually made. The full list is in how to verify a Chinese supplier: 12 checks before you pay.
Titanium from Baoji: grade, mill and paperwork
Baoji titanium is sold by companies of very different kinds: mills that melt titanium sponge into ingots, processors that forge, roll and machine, and traders that buy and resell. Each can be a fine supplier, but the paperwork chain is what protects you.
Grade. State the grade and standard, for example Grade 2 or Grade 5 (Ti-6Al-4V) to ASTM B348 for bar or B265 for plate and sheet. Grade 2 and Grade 5 look the same and differ a lot in price.
Mill test certificate. Ask for the certificate with the heat number, chemical composition and mechanical properties, and check that the heat number is marked on the material.
Who melted it. If the supplier did not melt the ingot, ask which mill did, and check that the certificate comes from that mill.
Material check at inspection. A handheld spectrometer test on the goods confirms the alloy grade before shipment. It is quick and cheap compared with the cost of a wrong grade.
Motors, transformers and electrical equipment
This is the area I know best. The common problems are not fake factories. They are specification gaps:
Nameplate versus quotation. Power, voltage, frequency, speed, efficiency class, insulation class and protection rating should match the contract exactly.
Copper and core. Copper windings or aluminum, and the grade and stack length of the core steel. These drive efficiency and life.
Explosion-proof certificates. For hazardous areas, check the explosion-proof certificate number and the protection marking with the issuing body, and check that the certificate covers the exact model and frame size.
Test report. No-load and load test results for your unit, with the serial number, not a type test for the model.
Trucks and truck parts
For trucks, ask whether the seller is an authorized dealer or exporter, check the vehicle identification number and engine number of the exact unit, and confirm the configuration: engine model and emission standard, gearbox, axle ratio, cab and tires. For parts, check whether they are original, approved replacement or aftermarket, and price them accordingly.
How a local visit works
Because I live in Xi'an, travel costs for a factory in the city or in nearby Xianyang are small, and a visit is easier to schedule than one that needs a flight. Baoji is a short high-speed train ride away. For factories in Xi'an I can also do follow-up visits during production and at loading without large travel costs, which is useful for larger or longer orders.
Questions to send a Xi'an or Baoji supplier first
Send these before you discuss price. A real manufacturer answers them quickly and specifically. Vague answers, or answers that change later, tell you a lot.
What is your full company name and unified social credit code, and where is the product made?
For titanium: which grade and standard do you quote, and which mill melted the ingot?
For titanium: will the mill test certificate show the heat number marked on the material?
For motors and electrical equipment: please send a nameplate photo and the routine test report of a unit of this model.
For explosion-proof equipment: which certificate number covers this model and frame size?
For trucks: please send the VIN, engine number and configuration of the exact unit.

Payment and inspection
Pay the company named in the contract, to a company account in that name.
Write the grade, standard, ratings and test requirements into the contract, so the inspection has something clear to check against.
For titanium, link the balance to a material check and certificates matched to heat numbers. For motors and electrical equipment, link it to witnessed tests and a nameplate check.
When to ask me to check
Ask for a check when a Baoji titanium supplier cannot tell you which mill made the material, when a Xi'an sales office cannot show you where the product is made, when motor or transformer specifications on the quotation do not match the nameplate photos, or when you want someone on site during production and loading without paying for flights.
Supplier verification costs US$79 per supplier, or US$60 each for five or more, and takes 3 to 5 business days. An on-site factory audit starts from US$299 per factory plus travel at cost, and in Xi'an that travel cost is small. For motor suppliers in eastern China, see Changzhou electric motor factories and Taizhou and Wenling pump and motor suppliers. All regions are in the guide to China's manufacturing regions, and you can read more about me.
