1. MOQ is high and a first order feels risky
What we do: Start with one carton (20 pcs) of padlocks or 30 sets of door locks. Mixed models inside one trial order are accepted, so the first order can test a range.
Why Buyers Choose Us
We only make smart locks, so the fit, the app version and the lead time can be answered in the same reply as the price. As a source factory we own the assembly, the function testing and the export documents, which is what makes that possible. Below is what it means in practice, written as specific actions rather than adjectives.
Six Things We Do Differently
Not claims about quality. Six specific things you can hold us to, and check against another quotation line by line.
2. Messages go unanswered and the project stalls
What we do: Quotes go out within 12 working hours and are issued as a document, with the open questions listed so nothing is left to a chat message.
3. The lock arrives and it does not fit the door
What we do: Send a photo of the door edge or a drawing. We confirm mortise size, backset, door thickness and hole pattern in writing before production.
4. The app cannot unlock the lock
What we do: Tuya Bluetooth and TTLock versions support active unlock from the app. The older Tuya Wi-Fi version is request-based, and we say so before you buy.
5. Nobody will take a non-standard specification
What we do: Non-standard mortise length, stainless steel versions, custom panel sizes and finishes are engineered and sampled instead of refused.
6. A quality problem ends the relationship
What we do: Batch defects get a written root-cause answer plus replacement parts, a credit or a swap in the next shipment, with spare parts added to a later order.
Compare Supplier Type, Not Just Unit Price
An international brand, a trading company and a factory are three different businesses. The unit price is not measured on the same ruler, and neither is what happens after the order.

| Who owns production | We do: assembly, function testing and packing |
|---|---|
| Who confirms the drawing | We do, in writing, before the run starts |
| Who issues the documents | We do: Form E, invoice, packing list and B/L |
| Who answers a batch fault | We do, with a root-cause answer and replacement or credit |
| What is not ours | Components we buy in, such as boards and readers |
What a Factory Quote Includes That a Trading Quote Often Does Not
- A drawing check before production, not a re-order of the same box
- One person accountable for the fit question, the app version and the price
- Export documents issued under our own name
- A batch trace that points at a component supplier when something goes wrong
None of that shows up in a unit price column, which is why comparing two quotations means comparing what is attached to them.
Certification: What It Covers and What It Does Not
A certificate applies to a specific model and a specific scope. We would rather draw that boundary before the order than after the goods land.
Swipe the table sideways to see the full specification →
| ISO 9001:2015 | Our quality management system, not a product certificate |
|---|---|
| SGS verification | A factory assessment, not a product approval |
| CE / FCC | Electronic compliance for the covered models |
| RoHS / REACH | Restricted substances, relevant to European and Middle East clearance |
| Salt spray ISO 9227 | A corrosion test result, not a warranty against a coastal site |
| Building-code ratings | Not held; tell us the standard and we will say so plainly |
How to Check Any of It
- Ask for the certificate that names your model and read the scope line
- Book a video factory tour and watch the assembly and inspection area
- Order a sample and test the app version yourself
- Ask for the batch record on a previous order
Every one of those is available before you commit to a volume order.

The Four Concerns That Come Up Most
These are the objections we hear when a buyer is comparing quotations. Each one is written as the worry first, then what we actually do.
7. Documents are missing and the goods sit at customs
What we do: Form E, commercial invoice, packing list and B/L are issued in house, and invoices can be issued in the form your customs broker requires.
8. I buy through a forwarder in China and other suppliers will not cooperate
What we do: We deliver to your nominated forwarder warehouse, print your shipping marks and send packing photos before dispatch.
9. Battery products cannot be shipped
What we do: Where regulations require it, battery-containing locks are re-routed and separately manifested, and the documents match the route used.
10. Private label feels like a gamble
What we do: Logo, colour box, manual language and master carton marking are all built from your artwork, with a digital proof approved before printing.
What We Do Not Claim
- We are not the largest lock factory in Wenzhou and we do not claim to be.
- We do not quote capacity or lead times we have not confirmed with the production team.
- We do not grade our own products with adjectives; we describe the checks each one passes.
- We do not promise a certification we cannot put in a PDF for your model.
If a requirement is outside what we can do, we say so at quote stage. That is cheaper for both of us than a claim that fails at customs or in the field.
Four Questions About Choosing Us
The four questions buyers ask when they are comparing quotations.
Choosing a supplier
How are you different from a trading company?
A trading company coordinates other people's production. We run the assembly and testing, confirm the drawing against the door, and issue the export documents ourselves. The difference shows up when a measurement is wrong or a batch has a fault.
Why is your price not the lowest quotation I received?
Because the quotation includes a warranty that is honoured, documents issued in house, and the hardware generation you actually asked for. A cheaper quote is often cheaper because one of those three is missing.
Do you only make smart locks?
This website and this line of the business cover smart locks only: smart door locks, smart padlocks and the gateways and bodies that go with them. That focus is why the fit and the app questions get answered in the same reply as the price.
How do I verify what you say?
Ask for the certificate for your model, book a video factory tour, and order a sample before the bulk run. All three are available before you commit to a volume order.
Start With the Smallest Order That Answers Your Question
A sample answers whether the lock fits. A carton answers whether it sells. Neither requires a volume commitment, and both are quoted the same working day.
- Reply within 12 working hours
- Samples in 3-7 days, refundable against the first bulk order
- Fit and app version confirmed in writing before production
