Cooperation
Partnership and order terms for lock supply
We supply self-storage hardware to operators, distributors and door-system suppliers. Here is exactly how an order runs, what it costs to start, and what happens if something goes wrong.
Who we cooperate with
Three partner types, three different conversations. The common thread is that the specification has to survive a re-order two years from now.
Operators and facility groups
New-site fit-out, replacement cylinders, overlock hardware and a unit key plan as one package.
- Documented unit lock specification with photos and cylinder size
- Key plan per site, with a group-level manager-key rule
- Re-order path so a cylinder bought later still matches the original keys
Distributors and wholesalers
Volume pricing, private label and a predictable supply rhythm for the models you resell.
- Configuration-based quotations, not a single headline number
- Your logo on body, keys and packaging
- Consolidated shipments from Ningbo or Shanghai
Door and hardware manufacturers
OEM components to your drawing, so your door line does not absorb our tolerances.
- Tight hole and bore tolerances, verified by First Article Inspection
- Structural changes and CAD review
- Tooling quoted separately and transparently
Process
How an order runs
Six stages. Each one ends with something you approve, so nothing is built on an assumption.
Requirement review
You send the model or drawing, the change, the quantity and the destination. We confirm feasibility, cost impact and MOQ.
Sample
A physical sample from 5 days. You check fit and finish against your actual door.
Confirmation
Artwork proof, serial number file and specification signed off before production.
Production
Batch production with inspection records, averaging around 30 days.
Inspection
Final inspection plus pre-shipment photos and video sent for your approval.
Packing and delivery
Export packing, documentation and shipment on your terms — including DDP where available.
Fast-track options
If timing is critical, tell us the deadline at the first message rather than at the end. We will tell you honestly what is possible instead of promising a date we cannot hold.
- Sample in parallel with artwork approval
- Partial shipments against a phased site schedule
- Selected high-runner models from production stock
One named contact per order. You deal with the person who quoted it, not a rotating inbox.

Every figure above is a commitment. Where a value is not yet confirmed for your model, we say so instead of quoting a default.
How payment works
- Standard terms
- First orders typically run a deposit with the balance against the shipping documents. Repeat orders are agreed per order rather than assumed.
- T/T
- Bank transfer in USD, EUR or CNY. Bank charges are stated on the quotation, so the amount that arrives matches the invoice.
- L/C
- Irrevocable letter of credit at sight against the required document set. Send the draft wording before the order and we will remove discrepancies before the bank sees them.
- Card and online payment
- Available for samples and small trial orders where a bank transfer would be disproportionate.
- Tooling and samples
- Tooling is invoiced separately from production and the sample fee is refundable against the bulk order — both stated on the quotation instead of being absorbed invisibly into the unit price.
- Currency
- Quoted in the currency printed on the quotation, and not adjusted after acceptance.
How freight and clearance work
- Trade terms
- EXW, FOB, CIF, CFR or DDP, printed on the quotation so two suppliers can be compared at the same point in the journey.
- Ports and consolidation
- Ningbo and Shanghai. Mixed families are consolidated into one shipment rather than split across departures.
- Packing for sea freight
- Export cartons with your label, palletised or loose-loaded as agreed. Units per carton and the total carton count appear on the packing list.
- Documents
- Commercial invoice, packing list and HS code, plus the declarations that apply to the models ordered — including CE-RED and the battery transport documents for the Bluetooth lock.
- DDP scope
- Where DDP applies, freight, clearance and duties are included and the figure is the landed number. Outside that scope, duties are settled by the importer.
- Insurance
- Under CIF we arrange minimum-cover marine insurance as the term requires; under FOB and EXW the cover is arranged on your side. Additional cover can be quoted on request.
- Multi-site delivery
- One destination for onward distribution, or split shipments scheduled per site against your rollout plan.
Support, delays and after-sales
What happens when the plan meets reality.
- Response
- Most enquiries answered within 4 business hours; a named contact stays on your order.
- Order visibility
- Production status updates at each milestone, not only at shipment.
- Pre-shipment approval
- Photos and video of the finished batch before the goods leave.
- Delay handling
- If a delay is caused by our side, we notify you as soon as we know and agree a remedy against the order impact.
- Quality claims
- Handled against the agreed specification and inspection record, with a documented corrective action.
- Replacement supply
- Re-orders run against the stored specification, so keying and dimensions stay consistent.
Business FAQ
What payment terms do you accept?
Payment is by T/T, L/C or credit card. A first order normally runs on a deposit with the balance against the documents or on shipment, and repeat orders are agreed on their own terms. Alibaba Trade Assurance is supported for qualifying transactions, and the currency is confirmed with the quotation.
What is the minimum order quantity?
Standard MOQ starts from 500 pcs for the mechanical self-storage lock families. The Bluetooth smart padlock starts from 50 pcs. Orders with heavy customization — a new mold, a special key system, printed blister cards — may require more. The exact MOQ is confirmed with your quotation, before you commit.
What are the lead times?
Samples from 5 days. Batch production averages around 30 days after the order and artwork are confirmed. Actual lead time depends on model, quantity and season; peak periods such as Chinese New Year should be planned in advance, and we flag them when you order.
What happens if something is wrong with the order?
Every order runs against an agreed specification and a documented inspection record. If a confirmed quality issue occurs, we handle it against that specification with a recorded corrective action — repair, replacement or credit, negotiated on the actual quantity affected.
Do you offer a warranty?
Warranty period and scope are confirmed per product, finish and order contract. We state the terms in the quotation rather than advertising a blanket warranty that may not apply to your configuration.
Can you hold stock for regular supply?
Selected high-runner items may be available from regular production stock. Availability changes, so we confirm the current position for the model you need — we do not list every item as in stock.
