Trace the product route
Start with the approved product reference and identify the material preparation, forming, assembly, finishing, testing and packing stages relevant to it.
Quick answer
Check the factory behind the quotation
LIFA reviews the production site, equipment and process claims behind a Chinese supplier’s quotation. We compare the available evidence with your product, order quantity and timeline, then organize findings and questions for your next decision.
Supplier verification focuses on company and transaction records. Factory verification asks whether the claimed facility can support the product and work proposed. The agreed scope can use a document review, live video, a site visit or specialist audit coordination; each gives different evidence and has different limits.
- 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.
When to use this service
Use factory verification when a supplier profile does not answer where your product would be made, which processes happen there or whether the proposed production route suits the order.
05
Factory reality is unclear
Supplier profiles, sales offices, showroom photos, and factory claims do not always prove where or how production happens.
Discuss This06Capacity claims need context
Output numbers, equipment lists, worker counts, and lead times should be checked against your product and order quantity.
Discuss This07Audit questions are too broad
Turn a broad audit request into specific production and quality questions. Include the product model, specification revision, sample reference, critical process and expected evidence. Keep corrective actions open until a recheck supports closure or you accept the stated limitation in writing.
Discuss ThisWhat LIFA reviews and what you receive
We turn your product requirements and factory concerns into a scoped review. The output identifies supported findings, access limits, unanswered questions and next-step options.
08
Factory claim review
Organize the factory name and address, supplier role, relevant product category, proposed production route and available documents, photographs or videos.
Discuss This09Capacity questions
Ask which lines, machines, materials and processes would handle the order, including sample history, current load, output assumptions and lead time. Keep capacity claims tied to the product, quantity and delivery plan. Compare quotation exclusions and separate sample, tooling, packing or logistics costs in the later commercial review.
Discuss This10Remote or visit preparation
Agree the review method, site and production areas, product reference, evidence requests, access permissions and timing. Remote review, live video, an arranged visit and a specialist audit require different preparation and are quoted to scope.
Discuss This11Decision notes
Summarize what was reviewed, the source and date, exceptions and follow-up owners. Link any proposed material, quantity, tooling, packaging, quality, freight or payment change to a revised quotation so you can assess its cost and timing before approval.

Service in practice
Review the operation your product depends on
A machine list or factory photograph is useful only when it answers a question about the product and production route you intend to use.
On-site, not paper-only
Match equipment and process claims to the required work.
Compare the proposed process with the equipment, staffing, tooling and workshop evidence available. If the agreed scope includes a visit, record what is observed on site; document or video reviews must be identified as such.
Product-specific review scope
Check relevant production steps, equipment, material flow, storage, quality controls and stated capacity against the supplier’s original claims and your product requirements.
Dated evidence and access limits
Keep dated photographs, video notes, documents and findings with the location and review scope. Record areas that were not accessible, operations not running, unanswered questions and the next buyer decision. This gives useful context beyond a pass/fail label.
Verification decision brief
Ask which steps happen here and which happen elsewhere
A factory may complete some operations in house and send others to another facility. Follow the actual product route so the review covers the work that matters.
Review the critical operation
Ask for equipment, process and quality evidence for the step most likely to affect the requirement. Keep photographs, measurements, documents and exceptions attached to that question.
Record external dependencies
Record subcontracted steps, external sites and the supplier’s control over them. Accept, correct or escalate the finding before carrying the agreed route into production, inspection, packing and release planning.
On the ground
Choose the review method your decision needs
LIFA can coordinate factory visits across China’s manufacturing regions. Agree the location, access, scope and timing before booking. A visit can provide direct observations and photo or video records; a remote review can help prepare targeted questions but has different limits.
- For a site visit, agree which production areas, equipment and working conditions can be observed.
- Record photographs, video notes and documents within the agreed access and permission scope.
- Discuss capacity, lead-time and subcontracting claims with the responsible factory staff.
Compare the evidence each method can provide
- Documents and live video
- Review supplied records and ask targeted questions remotely. Record what was shown, by whom and when; unseen areas and independent confirmation can remain open.
- Arranged site visit
- Observe agreed areas and operations at a stated location and time. Record access restrictions, inactive processes and anything outside the visit scope.
- Specialist audit
- Use a defined assessment scope, criteria and competent auditor for a deeper question. Agree the deliverable and limits; a factory audit does not replace product-specific testing or shipment inspection.
What buyers should prepare
The factory review should focus on the exact product, order size, and risk points the buyer needs to clarify.
Supplier and factory details
Supplier link, factory name, factory address if available, contact person, business documents, and any factory photos or videos already received.
Product and production needs
Product specifications, materials, process requirements, target quantity, samples, target price, packaging, and timeline.
Factory claims to check
Production line claims, equipment lists, worker count, export experience, quality process, certificates, or subcontracting concerns.
Preferred verification level
Remote review, video call, China-side visit support, third-party audit coordination, or deeper pre-production review.
Prepare a focused factory-review brief
Use the blank CSV to connect each production claim to the requirement, review method, evidence request and next decision. Keep unobserved areas and unresolved questions visible.

If deeper checking is needed, LifaSourcing.com helps organize questions for a factory visit, live call, or third-party audit scope.
05
Next-step planning
The review can move into samples, quotation comparison, quality control planning, inspection coordination, or supplier replacement.
In practice decision brief
Follow each requirement through a check and a record
A useful checklist connects the buyer’s requirement with the evidence available at the factory. It should show what was checked, how and with what limitation.
Use a defined reference
Use the relevant specification revision, sample, process requirement or agreed checklist. Choose evidence appropriate to the question: observation, measurements, photographs, production records or staff explanations.
Describe the finding
Record the location and date, source, review method, result and any difference from the requirement. Distinguish a factory statement from an observed or documented fact.
Close or carry forward the exception
Name the owner and expected evidence for each corrective action or further check. The buyer decides whether to accept, request a recheck or escalate before the next production, inspection, packing or release step.
Turn factory findings into the next action
Keep factory findings, supporting records, limitations and the next action together so buyers can decide what to verify before committing.
Trace the production questions
Ask where each production step happens, which equipment handles it and which operations depend on another facility. Keep the reply with the process and site it describes.
Make the difference visible
Attach a finding to the exact model, specification revision, sample or batch involved. Record the method, observed difference and proposed correction. Keep the issue open until a recheck provides evidence or the buyer accepts the limitation.
Carry the reference into samples
Use the reviewed requirement when requesting samples, planning deeper audits or adjusting supplier choice. Preserve the source, action, owner, deadline and dated buyer decision, including earlier versions when the requirement changes.
Factory verification risks to review early
A factory review describes the evidence available within its scope and at the time of the check. Use it alongside samples, written terms and later production or shipment controls.
12
A showroom is not a production line
Record the actual production address, the supplier’s role and the evidence connecting that facility to your product. Office or showroom photographs alone leave the production-location question open. Assign an owner to follow up before the next buyer decision.
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.
Discuss This14Capacity can change with season and order load
Current order load, staffing, material availability, subcontracting and seasonality can change the production plan. Ask for the assumptions behind the proposed output and lead time, then revisit them when the order or schedule changes.

Buyer decision notes
Understand what the factory review establishes
A scoped review supports a decision about the production route. It does not replace product testing, ongoing quality controls or a shipment inspection.
Which real, reviewed case demonstrates this service?
The artwork here illustrates the method and is not evidence of a completed customer visit. Ask LIFA for a relevant, shareable record showing the product requirement, review method, location, findings, limitations and buyer decision. Confidentiality may restrict available examples. Use a qualified specialist for testing, customs, legal, tax or regulatory judgments.
What should the buyer record before the next approval?
Record the requirement, factory and review scope, supporting evidence, unresolved issues and the buyer’s dated decision. Link the record to later quotations, samples, batches, inspection findings, payments and shipment references so the next reviewer can see what changed and why.

Common questions about factory verification
Clear answers help buyers use factory verification as practical risk reduction, not as certainty.
We help check the production site, equipment, capacity and processes claimed by a factory. The agreed scope may include a site visit or remote review, with findings for your decision 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.
Send the supplier link, factory details if available, product information, order quantity, destination country, and main concerns to simon@lifasourcing.com or WhatsApp +86 173 7653 5037.
Start with the decision you need to make. Documents and live video can clarify specific claims remotely. A site visit can add direct observations of agreed areas at an agreed time. A specialist audit uses a defined assessment scope and competent auditor. Agree the product, criteria, access, evidence and deliverable before choosing; none of these methods establishes every future production outcome.
Record what was requested, what was refused or unavailable, and how that limits the review. Ask whether another source, a live demonstration or a revised visit scope can answer the question. You can postpone the commitment, request deeper checking or consider another supplier; unavailable evidence should remain visible in the decision record.
