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.
Approved with records
Sample approvals are backed by notes, not just a yes or no.
Requests are placed with the factory, tracked through production and courier, and reviewed against the original brief so the approval decision is based on documented details, not memory of what was asked for. Keep the owner, open questions, and buyer approval visible as work moves forward.
Spec matching
Sample dimensions, materials, and function are checked against the original buyer brief before approval is requested. 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.
Shipping & tracking
Courier details and delivery timing are coordinated so sample review isn't delayed by a lost or unclear shipment. Keep the owner, open questions, and buyer approval visible as work moves forward. Use shipping & tracking to assign every cargo handoff: supplier release, pickup, export clearance, main carriage, import clearance, storage, and final delivery. Confirm packed data and document readiness first, then compare price and timing without hiding destination charges, free-time limits, or route assumptions.
Quick answer
Sample coordination turns a supplier promise into something buyers can review
Product samples help buyers test material, finish, function, packaging, labeling, and supplier communication before approving a larger order. But a sample is useful only when the requirement, cost, courier handoff, revision history, and approval notes are written clearly.
LifaSourcing.com organizes China-side sample communication and tracking so buyers can compare supplier options before committing. Buyers remain responsible for final approval, compliance review, payment decisions, and bulk order authorization.
Buyer problems
Where sample work usually goes wrong
Small sample mistakes can become expensive production mistakes when the approval record is vague.
05
The sample is requested without a clear spec.
If material, size, color, function, packaging, and acceptable differences are not written down, suppliers may send what is easy instead of what the buyer needs. Connect the sample is requested without a clear spec 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.
View Service 06Revision rounds are not tracked.
When each version is not logged, buyers lose the reason. Treat revision rounds are not tracked 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 This 07Sample approval is mistaken for production approval.
A sample can be a reference, but bulk goods still need production follow-up and inspection planning before shipment decisions are made. Connect sample approval is mistaken for production approval 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.

How LifaSourcing.com helps
What must the buyer provide before work can begin?
The goal is not to rush samples. The goal is to make each sample round useful for comparison, correction, and future inspection reference.
08
Sample request preparation
Organize product details, reference photos, target materials, size, finish, packaging, label notes, quantity, and review points before supplier communication. Define sample request preparation before the check takes place: measurable requirement, sampling or test method, tolerance, critical and non-critical defects, evidence format, and pass, hold, or fail authority. The decision record should preserve the original finding instead of replacing it with a later correction.
View Service 09Supplier communication
Coordinate supplier replies about sample cost, sample lead time, courier fee, customization limits, available colors, and production differences. Leave the next owner a clear handoff, including open questions and delays. The record for supplier communication names the contracted entity, production location, product fit, capacity evidence, quotation scope, sample reference, and open questions. Compare those points consistently within this page's sourcing brief and pause approval when identity, bank, capability, or specification details conflict.
View Service 10Revision and comparison notes
Track what changed between sample rounds and summarize differences between supplier samples so buyers can review with clearer context. Review revision and comparison notes 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 This 11Approval handoff
Keep the approved sample notes ready. Leave the next owner a clear handoff, including open questions and delays. Before moving forward with approval handoff, confirm that its required inputs are complete, material conflicts are visible, and the next owner knows the expected output and escalation path. The buyer should approve supplier choice, commercial terms, specification changes, payment, and cargo release in writing.

On the ground
Samples handled and reviewed in China first
A sample tells the truth faster than any chat message. LifaSourcing.com receives samples in China, reviews them hands-on against the buyer’s requirements, and documents findings before samples travel internationally.
- Samples inspected physically — materials, finish, function, and packaging.
- Photos, measurements, and notes shared before international forwarding.
- Multiple supplier samples compared side by side in one review.
Process
How sample coordination is organized
A controlled sample round gives the buyer a better basis for supplier selection, product correction, and bulk-order decisions.
01
Sample brief review
Review product references, supplier links, target quality, packaging, destination, courier needs, and questions the sample should answer.
02
Supplier request
Ask suppliers for sample availability, cost, lead time, customization limits, courier details, and what differs from bulk production.
03
Courier tracking
Coordinate pickup or dispatch details and keep tracking information organized until the buyer or agreed recipient receives the sample.
04
Review and revision
Record buyer feedback, supplier explanations, and correction points if another sample round is needed before approval.
05
Approval record
Keep written approval notes so production, packaging, QC, and inspection can refer back to the agreed sample standard.
Risk reduction
A good sample file protects the next sourcing step
The approved sample should be tied to a written specification, not just a photo or casual message. This helps the buyer compare suppliers, explain revisions, and prepare inspection points before bulk goods are accepted.
Separate sample approval from bulk approval
Bulk production can still vary, so sample approval should lead into production follow-up and inspection planning.
Confirm courier cost and timing early
Sample cost, courier account, packaging, and dispatch timing should be clear before suppliers prepare samples.
Keep an approval record
Write down the version, date, supplier, differences, buyer decision, and any points to correct in production.
Prepare first
What buyers should send before requesting samples
Clear sample input saves time, avoids wrong courier shipments, and makes supplier answers easier to compare.

Product details
Photos, links, dimensions, materials, colors, functions, finish standards, and any existing sample to match. Start product details with the product facts that determine the rule: function, material, model, user, electrical or radio features, packaging, origin, destination, and marketing claims. Record the official source and effective date, then carry approved requirements into the specification and inspection checklist.
View Service13Supplier list
Supplier contacts or product links if already available, plus any quote, catalog, chat history, or previous sample notes. Before approving supplier list, 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 This14Review points
What the sample must prove: material, function, packaging, labeling, fit, finish, durability, assembly, or market presentation. The record for review points identifies the destination rule, source and date checked, product configuration, responsible legal party, required label or document, and evidence status. Supplier statements can help collect information, but they do not replace current authority, laboratory, customs, tax, or legal review.
Discuss This15Courier details
Destination address, courier account if available, deadline, sample quantity, packaging needs, and who pays each fee. Compare the full scope before calling a quote a saving. The destination brief for courier details names the country, buyer or importer role, product configuration, sales channel, required documents, labels, route, and final-delivery point. Record authority and specialist checks separately from supplier claims so unresolved market-access questions stay visible before production.

In practice
Sample photos, records, and handoff details should stay connected
Sample coordination is most useful when supplier communication, physical samples, packaging, revision notes, and future inspection standards are kept in one sourcing record.
Supplier communication
Sample questions, fees, lead time, courier details, and revision notes are kept visible. Compare the full scope before calling a quote a saving. Before approving supplier communication, 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.
Courier handoff
Sample dispatch, tracking, and packaging condition are organized before the buyer receives the sample. Leave the next owner a clear handoff, including open questions and delays. The controlled record for courier handoff distinguishes coordination work from approval authority. Record the source information, action taken, exception, deadline, and buyer disposition, then preserve earlier versions so the decision trail shows what changed rather than only the latest status.

Buyer decision notes
Prepare for Sample Coordination
Settle these practical questions before applying Sample Coordination to a live supplier, order, quality, compliance, or shipment decision.
Exactly what is included and excluded from this service?
Sample Coordination includes only the activities stated in the written scope and quotation. Supplier selection, product specification, commercial approval, payment, market access, tax, legal decisions, and specialist testing remain with the buyer or appointed provider unless the agreement says otherwise. Third-party charges and exceptions should be listed separately before work begins.
Which decisions require written buyer approval?
The Sample Coordination record should show written buyer approval for the final specification, selected supplier, sample or golden sample, quotation and exclusions, tooling, contract, payment milestone, material change, inspection disposition, shipping mode, and cargo release. Operational coordination can prepare each decision, but it should not replace the buyer's commercial, compliance, or payment authority.
What determines the fee, third-party cost and expected timing?
The Sample Coordination fee and timing depend on the written scope, product and supplier complexity, number of options or inspections, locations, document quality, and required handoffs. Testing, travel, samples, tooling, freight, duty, tax, and other third-party charges remain separate unless a quotation includes them. The written quotation takes precedence over general page guidance.
