Evidence to collect
Photos, measurements, documents, and exceptions tied to the approved specification.
Service in practice
What happens when evidence is missing, inconsistent or unacceptable?
This service is built around the practical details buyers need before approving suppliers, samples, production, inspection, or shipment.
On-site, not paper-only
Production claims are checked on the factory floor before you commit.
Equipment, staffing levels, workshop capacity, and business registration are confirmed in person rather than taken from a supplier's own description. The visit is documented so buyers can review evidence before quotations move forward. Keep the owner, open questions, and buyer approval visible as work moves forward.
Audit checklist
Production lines, staffing, storage, and stated capacity are cross-checked against what the supplier originally claimed. Keep the owner, open questions, and buyer approval visible as work moves forward. Leave the next owner a clear handoff, including open questions and delays.
Photo & video evidence
Visual proof from the visit is shared with the buyer, not just a pass/fail badge, before any deposit is discussed. Keep the owner, open questions, and buyer approval visible as work moves forward. The note for photo & video evidence connects the requirement, supporting document, unresolved question, owner, deadline, and next buyer decision. Keep those elements together on this page so later reviewers can see what changed and do not have to reconstruct the reasoning from messages.
Quick answer
What does factory verification support include?
Factory verification support helps buyers review whether a supplier's factory claims make practical sense before samples, deposits, or production. It can include factory address questions, production capacity signals, equipment notes, process review points, photos or video requests, and audit preparation.
This is different from supplier verification. Supplier verification reviews company and document signals; factory verification focuses more on the production location, process capability, factory conditions, and whether the claimed facility fits the buyer's product and order.
- Review factory claims against product type, order quantity, and process needs.
- Prepare clearer questions before remote review, site visit, or third-party audit.
- Organize findings so buyers can decide whether to continue, verify deeper, or change route.
Exactly what is included and excluded from this service?
Factory verification is useful when a buyer needs more than a supplier profile but is not ready to trust production claims blindly.
05
Factory reality is unclear
Supplier profiles, sales offices, showroom photos, and factory claims do not always prove where or how production happens. Review factory reality is unclear against one product brief: legal seller, factory role, relevant capability, MOQ, sample status, quotation basis, and unresolved claims. Record the source and date for each material check, then return gaps for buyer approval before a deposit or supplier selection.
Discuss This06Capacity claims need context
Output numbers, equipment lists, worker counts, and lead times should be checked against your product and order quantity. Use capacity claims need context to turn the page discussion into a decision record. State the requirement, compare evidence on one basis, mark assumptions and conflicts, assign the next action, and preserve the buyer approval that authorizes supplier, payment, quality, or shipment work to continue.
Discuss This07Audit questions are too broad
A factory review works better when the buyer knows which production, quality, equipment, or process questions matter most. Connect audit questions are too broad to the exact model, specification revision, approved sample, lot or batch, test method, defect class, result, corrective action, and release owner. Keep exceptions open until the buyer reviews evidence from a recheck or accepts the stated limitation in writing.

Factory claim review
Factory name, address, supplier role, product category, claimed production capability, and available evidence are organized. Compare the full scope before calling a quote a saving. Before approving factory claim review, separate supplier statements from documents or observations that support them. Match the legal entity, factory role, product process, quantity range, lead-time basis, and sample status to this page's requirement, then record who resolves each remaining exception.
Discuss This09Capacity questions
Questions can cover production lines, equipment, output, sample history, materials, lead time, and order-size fit. Compare the full scope before calling a quote a saving. Before deciding on capacity questions, normalize every offer to the same product, quantity, delivery term, packaging, inspection basis, and destination boundary. Flag unpriced items and conditional terms, because a lower quotation can shift cost, quality, inventory, timing, or risk elsewhere in the order.

On the ground
Factory visits arranged nationwide across China
Photos on a listing cannot show how a production line actually runs. LifaSourcing.com can arrange factory visits across China’s manufacturing regions, walking the floor, photographing production, and asking the questions a buyer would ask if they could be there.
- Production lines, equipment, and working conditions seen first-hand.
- Photo and video records collected during the visit for the buyer’s review.
- Capacity and lead-time claims discussed face to face with factory staff.

Factory verification risks to review early
A factory check reduces uncertainty, but buyers should still avoid treating one review as certainty.
12
A showroom is not a production line
Sales offices and showroom photos may not prove where your specific product will be made. Treat A showroom is not a production line as a specific control point on this page. Define what must be known, where the evidence comes from, which limitation remains, who decides, and what record closes the step; use a qualified specialist wherever legal, customs, tax, testing, or regulatory judgment is required.
Discuss This13One product line does not prove all capability
A factory may be strong in one material, process, or product type and weak in another. Use one product line does not prove all capability to compare suppliers on the same requirement rather than on marketplace rank or price alone. Check identity, manufacturing role, relevant process, quality controls, MOQ, timing, evidence, and quotation exclusions, with the buyer retaining the final selection and payment decision.
Discuss This14Capacity can change with season and order load
Lead times, staffing, subcontracting, and production pressure can affect whether a factory can handle your order. Review capacity can change with season and order load against one product brief: legal seller, factory role, relevant capability, MOQ, sample status, quotation basis, and unresolved claims. Record the source and date for each material check, then return gaps for buyer approval before a deposit or supplier selection.

Common questions about factory verification
Clear answers help buyers use factory verification as practical risk reduction, not as certainty.
LifaSourcing.com helps buyers organize factory claim questions, production capacity signals, equipment notes, process review points, site-visit preparation, remote review support, and next-step options before samples or production.
No. Factory verification reduces uncertainty by organizing available evidence and risk notes, but it cannot remove every production-quality, delivery, compliance, or supplier-performance risk.
Supplier verification reviews company information, documents, and communication. Factory verification focuses more on the production location, equipment, capacity signals, process conditions, and whether factory claims match the buyer's product needs.
Some factory checks can be supported remotely through documents, photos, videos, live calls, and supplier questions. Higher-risk orders may still require an in-person visit or third-party audit.
Prepare supplier links, product details, quotation, order quantity, factory address if available, sample status, destination country, and the specific factory claims you want checked.
