The bag sampling process turns a development brief into a physical product that buyers can review before approving production. Liora International Ltd’s sampling usually takes 5–7 working days, depending on the brief, materials and complexity; this is a sampling reference, not a batch-production or transit lead time. Separate technical development from preproduction approval, and confirm the scope, revision arrangements and quoted costs before work begins.
Build the timeline around decisions, not one delivery date
Start with an agreed brief covering dimensions, intended contents, materials, compartments, branding and quantities by style and colour. The bag development brief checklist covers those inputs in detail. For sampling, add the purpose of the requested sample, the person authorised to approve it and any material alternatives that need explicit permission.
Ask when the applicable sampling window starts and what must be available first. An incomplete drawing, unavailable lining or unconfirmed logo method can leave decisions unresolved before making the sample. Do not assume the 5–7-working-day reference includes custom-material sourcing, every revision, laboratory work or international delivery.
Plan distinct allowances for brief clarification, component sourcing, sample making, dispatch, buyer review and any repeat work. Working days and holidays also need confirmation. A required retail launch date should be communicated early, but it does not establish a confirmed delivery commitment.
For custom commuter backpack development, have the actual intended devices available for review. Waiting until a sample arrives to obtain device dimensions can lead to another construction round rather than a simple approval.
Technical sample versus preproduction sample
Sample names are not sufficient specifications. Agree what each stage will demonstrate and which details remain provisional. The following is a proposed buyer framework, not a statement that every Liora project follows identical stages.
| Sample stage | Main question | What the buyer should record |
|---|---|---|
| Technical or development sample | Does the design work physically? | Usable space, opening access, compartment layout, strap placement and construction changes |
| Revised technical sample, if needed | Have the agreed issues been resolved? | Each correction, any new issue and the updated specification version |
| Preproduction sample | Is this the agreed reference for production? | Materials, colours, trims, branding, workmanship and packaging scope, with outstanding exceptions identified |
A technical sample may use a substitute colour or component to assess shape and assembly. That substitution must be disclosed: approving the pocket layout should not accidentally approve a different zipper, fabric or lining. Where the substitute affects stiffness, thickness or fit, identify which conclusions need checking again with the intended material.
A preproduction sample should represent the agreed production specification. If bulk materials, a customised puller or final packaging are not yet available, record that limitation and decide how the missing detail will be approved. Do not call the product fully approved while a production-critical choice remains open.
SGS states that an approved reference sample for each product type clarifies comparison between a production batch and the ordered products. 1 The practical implication is to retain an identifiable physical reference alongside the written specification—not rely on an unlabelled sample or an old photograph.
What should importers and distributors pass to the inspection team? Agree who retains the approved reference and shares the matching specification, accepted exceptions and packaging requirements. Use the bag QC checklist and AQL guide to plan the separate production-inspection scope; a sample approval record is a comparison reference, not a batch inspection result.
Manage approval rounds with one revision record
The number of rounds depends on unresolved decisions; there is no universal promise that one sample will be enough. Before ordering, ask how many samples and revision rounds the quotation covers, what counts as a correction, and how a buyer-requested design change is treated commercially.
Nominate one person to consolidate comments from purchasing, product development and sales. Issue one dated response against the sample’s identifier and drawing version. Describe the problem, requested correction and acceptance point. For example, “the intended bottle cannot pass through the pocket opening” gives a clearer development task than “make the pocket better.”
What should a retailer include in the sample review? Bring the intended contents, logo artwork, labels and packing requirements into the same review. Record which product and presentation details are approved and which remain open, rather than treating a sales team's appearance approval as confirmation of fit, construction or final packaging.
Separate three outcomes: approved for the stated scope, changes required, or not yet evaluated. An appearance approval does not confirm loaded fit. A branding approval does not confirm strap construction. Photos can help review placement, but cannot establish every physical property.
Require a physical recheck when a change affects fit, structure or function. Some artwork or label corrections may be reviewed separately if both parties agree. After a revision, revisit affected features: enlarging one compartment can reduce space in another. Update the written specification and sample record together so approval refers to one consistent version.
Ask for cost categories, not an assumed sample fee
A useful quotation states what is included and what remains conditional. No standard fee, free revision entitlement or refund policy should be assumed. Request the applicable currency, payment terms and quotation validity alongside the scope.
| Quotation category | Questions to resolve before authorising work |
|---|---|
| Development and sample making | Are drawing preparation, pattern work, assembly and the requested sample quantity included? |
| Materials and components | Are stock options or specially sourced materials proposed? Who bears purchasing minimums or unused-material commitments? |
| Branding and tooling | Are artwork preparation, printing setup, embroidery development or custom moulds applicable? Who owns and retains any tooling? |
| Revision work | Which corrections are covered, and which specification changes require another quote? |
| Verification | Is third-party testing or inspection requested, and what scope and sample quantity are quoted separately? |
| Dispatch | Who arranges courier transport, and how are freight, duties and applicable taxes handled? |
How can an independent brand scope its first private label bag sample? List the features that need physical review and the branding decisions still open, then request a quote for that scope and its revision terms. Discuss these priorities through Liora's sampling and review capabilities before committing to custom components or additional versions.
Ask whether sample expenditure is credited against a later order, but do not treat a credit as confirmed until it is written into the project terms. Keep development expenditure separate from the unit price for batch production. Approving a sample does not by itself confirm the production quotation, quantity allocation or delivery schedule.
Liora’s typical carry MOQ is 300 units per style per colour; pilot requests are assessed case by case. The custom bag MOQ guide explains order-planning factors. Sampling acceptance is not an automatic agreement to produce a smaller batch.
Use a release checklist before production approval
This checklist proposes review points; it does not report Liora test results or promise a performance level.
- Identify the approved sample, specification revision, style and colour allocation.
- Check external and usable internal dimensions against agreed measurement points and tolerances.
- Pack the intended contents and assess access, closure, strap adjustment and compartment interference.
- Confirm materials, trim identities, colour references, logo position and workmanship requirements.
- Record packaging, labels and instructions, including anything approved separately.
- Close outstanding changes and document any specifically accepted exceptions.
- Confirm verification requirements and production arrangements separately from design approval.
Where load, water exposure or thermal performance matters, agree the method, conditions and acceptance criteria before making a claim. A brief handling check is not a substantiated load rating. The water-resistant versus waterproof guide explains why fabric evidence alone cannot establish whole-bag waterproofness.
Sample approval does not replace production inspection
Development sampling evaluates a proposed design. Production inspection evaluates goods or materials against agreed requirements. Intertek’s textile and apparel service description distinguishes preproduction incoming-material checks, during-production inspection and before-delivery inspection. 2 Those are separate inspection scopes, not evidence that an approved development sample proves the quality of every production item.
The current ANSI catalogue description of ISO 2859-1:2026 identifies single, double and multiple acceptance-sampling plans for inspection by attributes, indexed by acceptance quality limit, or AQL, for lot-by-lot inspection. 3 It is not a bag-development sample approval method or a zero-defect guarantee. If an inspection scheme is requested, agree the applicable edition, defect definitions and inspection arrangements with the provider; this guide supplies no proprietary sampling tables or Liora AQL commitment.
FAQ
Does 5–7 working days mean I will receive the sample within a week?
No. It is Liora’s usual sampling reference, subject to the brief, materials and complexity. Confirm the start point and dispatch date separately; courier transit, buyer review and additional rounds should not be assumed included.
Can I approve a technical sample made in the wrong colour?
You can approve clearly identified technical features while leaving colour approval open. Record the substitute and check whether its material properties affect the design. Final colour and any affected construction conclusions still need approval.
How many approval rounds should I budget for?
Ask for a quotation showing the included rounds and the treatment of further changes. Budget around unresolved features rather than assuming one universal number. Consolidated comments reduce conflicting instructions, but do not guarantee fewer rounds.
Is an approved sample enough to authorise batch production?
Only when the agreed approval scope is complete and the separate commercial arrangements are confirmed. Resolve material exceptions, verification requirements and the final specification first. Bring the sample-stage plan and open questions to Liora’s custom bag manufacturing enquiry before issuing production authorisation.
