When sourcing smart locks from China, I do not choose a supplier based on price alone. I first check whether the factory can consistently meet my requirements for quality, certifications, production capacity, customization, lead time, and technical support.

Here are the questions I would ask before choosing a new supplier.

How do I verify a Chinese smart lock manufacturer?

First, I verify whether the supplier is a real manufacturer and whether its factory matches the products being offered.

I would check:

• Company registration and factory information
• Production and assembly facilities
• Quality-control process
• Product certifications
• Existing project experience
• Factory inspection or video factory tour

1. How do I evaluate factory capability?

I look at whether the factory can handle my current order and future repeat orders.

The key points are:

• Production capacity
• Assembly and testing process
• Quality-control procedures
• Engineering capability
• Experience with bulk projects
• Ability to maintain consistent quality

2. What certifications should I check?

I check certifications based on the destination market and specific lock model.

Common certifications include:

• CE
• FCC
• RoHS
• UL
• ISO

3. What MOQ should I expect?

There is no single standard MOQ.

I normally expect the MOQ to depend on:

• Standard or customized model
• Order quantity
• OEM/ODM requirements
• Packaging customization
• Hardware or software changes

4. What is the typical production lead time?

I ask for the lead time for my specific model and quantity, rather than accepting a general delivery promise.

I also confirm:

• Sample lead time
• Mass-production lead time
• OEM/ODM development time
• When production officially starts

5. Can the manufacturer support OEM/ODM?

If I am buying for distribution or a branded project, I check whether the factory can customize:

• Logo
• Packaging
• Hardware
• Lock structure
• Mortise
• Software or App

6. What technical support is provided?

For smart locks, technical support is part of the product.

Before ordering, I want to know whether the supplier provides:

• Installation instructions
• Installation videos
• Product manuals
• App/software support
• Engineering assistance
• Spare parts

7. What should I check before placing a bulk order?

Before releasing a purchase order, I confirm these items:

• Final model and specifications
• Door thickness and lock-body requirements
• Access methods
• Quantity
• Certifications
• Packaging
• Production lead time
• Payment terms
• Warranty
• Spare parts
