Reference sample → written criteria → inspection

A clear reference. An agreed standard.

Quality starts with a shared definition of the product. Connect the specification, approved physical sample and packaging details before production decisions are made.

01 / Existing workflow

The reference stays at the centre.

This page brings together the workflow already described on our company and OEM pages. It does not present the illustration as inspection evidence or introduce new certification claims.

  1. Retain a physical reference

    The published company workflow calls for an approved reference piece held by both parties against the order number. Record the sample identity and approved specification revision so the same object anchors later discussions.

  2. Approve the pre-production sample

    Product and packaging are approved in writing before mass production. Record the item, materials, colour, edge and artwork version together; a design preview or photograph is not a substitute for that approval.

  3. Review during production

    The existing workflow describes a photo update at roughly 50% completion. Use the agreed reference to discuss visible colour or pack differences. Photos can communicate progress; they do not independently verify hidden material or performance properties.

  4. Plan the pre-shipment inspection

    Our published OEM terms specify AQL 2.5 pre-shipment inspection and welcome third-party or buyer inspection. Agree the inspection scope, sampling plan, defect classification and reporting requirements for the order. An AQL reference is not a guarantee of zero defects.

  5. Resolve documentation before dispatch

    Identify destination markets, required reports and packaging marks early. Confirm what evidence is needed for the exact product and market. This page does not claim that a specific item has passed a test or holds a certificate.

02 / Prepare the acceptance criteria

A specification checklist — not a test report.

The items below are proposed points for buyer discussion. Select the relevant checks and agree methods, tolerances and acceptance limits in writing. No test equipment, completed testing or performance result is implied.

Proposed review points for a microfiber programme
AreaWhat to defineWhat to agree or request
Material & constructionItem code, blend, GSM, weave or knit, pile and finished sizeMeasurement method, conditioning and tolerances appropriate to the selected cloth
Colour & appearanceApproved physical colour reference, visible marks and shapeViewing conditions, acceptable variation and defect examples
Edge & seamsSelected edge finish, seam construction and corner shapeAcceptance criteria for loose threads, seam consistency and any required seam evaluation
Use & careIntended surface, care label and claims proposed for retailAny lint, washing, colourfastness, absorbency or surface-suitability evaluation needed; method and evidence to be confirmed
Artwork & packingApproved artwork revision, label location, pieces per pack and carton marksDieline proof, pack count, barcode and text review against approved files
Market documentationCountries of sale and applicable material or labelling requirementsRequired reports and their product/material coverage; no report assumed available without confirmation

03 / Match the evidence to the item

One checklist does not fit every cleaning product.

Our catalogue spans microfiber textiles, cellulose products and other cleaning-tool materials. The company page explains which material domains sit within the joint-venture group and which are coordinated with partner factories.

For a microfiber item, focus on its selected construction, finish and intended surface. For other materials, develop an appropriate specification rather than reusing textile checks without review. Ask what evidence applies to the exact item, not just to a similar product name.

Send with your quality enquiry

  • Product code and current specification revision
  • Destination markets and intended use
  • Claims you plan to make on the packaging
  • Critical defects, acceptance limits and inspection expectations
  • Any buyer protocol or report requirements

Inspection arrangements and commercial details remain subject to the agreed order terms. We do not add a new fee policy or timing guarantee here.

04 / Close the loop

Approve, record, then control changes.

Keep written approval, the physical reference and final artwork together. If a size, material, colour, edge or pack changes, record the revision and discuss whether a new sample or evaluation is required. Resolve open points before proceeding rather than assuming the earlier approval covers a changed product.

Bring the specification into focus.

Send the item, intended use, quantity and destination market. Include the decisions you need the sample or quotation to resolve.
