- Ask who handles export and who handles production: LEIYU combines trade and manufacturing, with Qingdao Chenrui Mingwo Electronic Technology Co., Ltd. running LEIYU's export business and the Fengbao factory in Qidong, Jiangsu, making the tools.
- Inspection is possible: pre-shipment photos, pre-production samples, third-party inspection, and you can also audit the factory in person.
- Documents are checked per model: UN38.3 and MSDS are sent with the quotation.
- The warranty is written down: batteries and chargers 1 year, with a warranty card in the case.
- Payment is by T/T, to an account belonging to the company named in the contract and proforma invoice.
Who handles export, and who handles production?
Some exporters only trade and source goods from other factories; some factories only manufacture and do not export directly. Ask first who handles export and who handles production, so you know whom to contact if something goes wrong.
LEIYU is a sub-brand of Fengbao that combines trade and manufacturing: the Fengbao factory in Qidong, Jiangsu, manufactures, and Qingdao Chenrui Mingwo Electronic Technology Co., Ltd. runs LEIYU's export business. The factory opened in 2018, covers 14,000 m², has more than 160 workers and makes more than 400,000 tools a year in 2026.
There are three ways to tell a factory from a trading company. First, ask which processes happen in-house: are tool assembly, power testing and final packing done in the same place? Second, ask for a live video call from the production line showing the model you are asking about, not a pre-recorded tour. Third, ask for the registered company name and address, and check that the export documents carry the same name. Some factories export through a separate company; that is normal, but it should be explained at the start rather than discovered later. LEIYU works this way: Qingdao Chenrui Mingwo Electronic Technology Co., Ltd. runs LEIYU's export business, and the Fengbao factory makes the tools.
Look at the battery platform before the tool
First-time importers often compare a few drills against each other. But once customers own their first tool, they compare batteries: with two batteries and a charger already at hand, their next tool will be one that takes those batteries.
So for a dealer the battery platform decides three things: how many kinds of batteries and chargers you stock, how easily you can add new tools later, and whether customers keep buying your brand. Ask the supplier for a compatibility table by model showing which battery fits which tool. Whether the voltage is marked 20 V or 21 V is just a different way of writing it and says nothing about compatibility; if the mount and battery housing differ, the battery will not fit.
LEIYU has a single 21 V platform: four batteries, 2.0, 4.0, 6.0 and 8.0 Ah, with the Dayi A3-type battery mount common in China, shared by every 21 V tool; the only exception is the small XLY-16-10 drill, which uses its own 16.8 V battery.
Can you visit the factory?
Being able to see the factory is the most direct test. You are welcome to visit the Fengbao factory in Qidong, Jiangsu, and see the production line; please arrange the date in advance. If you cannot come, the production and inspection page has videos of the workshop, the assembly line and the warehouse.
How are goods checked before shipment?
Every factory sends a good sample; the question is what unit four hundred is like. Ask the supplier to describe the checks in order: how motors and cells are checked on arrival, what is checked during assembly, whether every finished tool is power-tested, how batteries and chargers are paired before packing, and how the final packing is checked against the order. Then ask one more thing: is every unit checked, or only a sample?
Every LEIYU tool is run on a battery once assembled: we listen to it, check the speed and try the settings, and a tool with a problem does not leave the factory. From components arriving to cartons being sealed there are four checks; the Production and Quality page sets out what each one covers.
Before shipment you can ask for three things: pre-shipment photos of the finished tools, labels, kit contents and sealed cartons; pre-production samples made with the labels and packaging you approved; and a third-party inspection, with the finished-goods and packing area opened to the inspection company on an agreed date.
Are documents issued per model?
For shipping lithium batteries, buyers ask most about UN38.3 and MSDS. The question is not whether they exist, but whether this model has them. LEIYU checks per model and sends them with the quotation; the tool, battery and charger may have separate documents.
| What it covers | Typical documents | Who asks for it |
|---|---|---|
| Lithium battery transport | UN38.3 test summary for the complete battery pack, MSDS safety data sheet | Forwarder, carrier |
| Other rules in the destination country | Different in each country | Confirmed by the importer |
Without a UN38.3 summary for the complete battery pack, a forwarder can refuse lithium batteries, so get it before you book transport. Rules in the destination country are for the importer to confirm; small orders usually ship DDP, so you do not have to clear customs yourself.
How are warranty and spare parts written down?
The warranty belongs in the quotation and the contract, not just in a verbal promise. LEIYU writes it this way: batteries and chargers carry a 1-year warranty with a warranty card in the case; LEIYU supplies spare parts by model, and replacement parts are included with the next shipment.
Not covered: batteries with water damage, drop damage or a replaced housing, and chargers with water damage or a cut or broken cable.
Two more things often come up only at the first warranty claim: which spare parts can be bought separately, such as switches, chucks, batteries and chargers, so tools can be repaired locally instead of being sent back to China; and what counts as a defect under warranty. Put the second one in the contract before the first order, so that after-sales support actually works.
Who receives the payment?
The company that receives the money must match the company in the contract. LEIYU is paid by T/T, to an account belonging to the company named in the contract and proforma invoice; bulk orders: 30% deposit, balance paid before the goods leave the warehouse; small orders and samples are paid in full before dispatch.
Check the name of the receiving company before paying. Any change of account is valid only if confirmed on WhatsApp or from our company email, so do not pay to any other account.
Is communication easy?
We communicate in Chinese, Russian, English, Kazakh and Uzbek and reply within 2 hours on working days; Monday to Sunday, 09:00-21:00 (UTC+5). One contact person follows you from enquiry to after-sales.
What this means for purchasing
- Inventory: One platform covering drills, grinders, saws and garden tools means one set of batteries and one type of charger in the warehouse; with two platforms, your battery stock doubles before you have sold a single tool.
- Positioning: Brushless motors and high-capacity batteries belong on the shelf for professional users; brushed motors and small batteries belong on the home-use shelf. Decide who you are selling to first, then choose the platform, rather than letting the price list decide for you.
- Specifications: Treat the torque and runtime figures on a product sheet as claims to check, not facts. Compare the sample with a tool your customers already know. LEIYU's rule is that motor ratings are not overstated and the rating plate shows the real figures, but you can still test the sample yourself.
- Future models: Ask the supplier what tools will be added to the platform. A supplier who keeps adding tools to the same battery is one you can work with long term; one who changes voltage every year leaves your customers with batteries they cannot use.
Seven questions to ask the supplier
- Which of tool assembly, power testing and packing happen in-house at your plant?
- Which batteries does this model take, and which other tools take the same battery?
- Which documents exist for this model, its battery and its charger, and can you send them?
- Is there a UN38.3 test summary for the complete battery pack?
- How is the private-label minimum counted per model and configuration, and what can be bought below it?
- Which spare parts can be bought separately, and how is a warranty defect defined?
- What checks are there between assembly and shipment, and are pre-shipment photos standard practice?
LEIYU's answers to these seven questions are on the Production and Quality, Battery Platform, Downloads and FAQ pages.
