Quality Assurance

Last updated: October 2026

Quality at Riway runs on documents and procedures, not slogans. Written procedures and batch records keep every step of production traceable. QC is split into three separate stages, so a problem missed at one stage is still caught at the next. Independent checks at each stage stop quality issues from slipping through.

In short: three separate control stages sit between your raw materials and your shipment — incoming material control, in-process control on the converting and packing line, and pre-shipment control before release. Each one is recorded against a batch record, and each one can hold a batch. This page explains what is checked at each stage, what documentation you receive, where these gates fall in the project timeline, and what happens when a check fails.

The three quality control stages

The three stages are independent on purpose: each covers a different failure mode, and a defect that survives one stage should be caught by the next rather than by your customers.

StageWhen it runsWhat is checked
1. Incoming material controlOn receipt, before anything enters productionNonwoven roll goods against the agreed specification (fibre, GSM, sheet width, roll condition); film structure, thickness and print; closure fit; carton quality; formula ingredients and their batch codes
2. In-process controlDuring converting and packing, per batchLine settings against the approved sample and spec; lotion loading and pack weight; sheet count, fold and stack; seal integrity; print registration; lid adhesion
3. Pre-shipment controlAfter packing, before the order is released100% quality inspection of the finished product before delivery; carton count and labelling; batch and shelf-life coding; retained samples; completeness of the document pack

Pre-shipment inspection is 100% of the finished product, not a sample of it — the same commitment Riway publishes on our OEM/ODM services page.

What is documented for every batch

The point of documentation is that any unit in your shipment can be traced back to what made it. For each batch we keep, and can retrieve:

  • the approved specification and the approved sample reference;
  • material batch codes for the nonwoven, film, closures and formula ingredients;
  • the line settings used for the run, including lotion loading;
  • in-process check results, recorded as the batch was produced rather than reconstructed afterwards;
  • the finished-goods inspection result and the release decision;
  • retained samples from the batch, so a later question can be compared against the physical product rather than a description of it.

Documents that travel with the shipment — certificates, test reports and declarations — are listed on our certificates and reports page, along with how to verify them independently.

Where quality control sits in the project timeline

QC is not a stage at the end of a project; it is a gate at each stage. The table below maps the project from first conversation to delivery, and shows what you approve, what you receive, and where the delays normally come from.

StageWhat happensWhat you approveWhat you receiveTimingWhat usually delays it
1. SpecificationRequirements clarified: product type, formula, material, packaging and quantityThe written specificationA written specification you can quote againstConfirmed before quotingThe specification still changing while quotations are being prepared
2. Sampling1–3 sample sets developed, including formula testing and packaging designThe physical sampleSample sets, plus confirmation of formula and packaging3–5 working days standard; 5–10 working days where formula, material or packaging changesArtwork, film structure or pack-format decisions arriving late
3. Order confirmationQuotation and contract issued against the approved specificationQuotation, contract and production cycleQuotation, contract, specification sheet, tooling treatmentSet in the quotationPayment terms or Incoterm not yet agreed
4. Material preparationSubstrate, film, closures and ingredients ordered to specification; incoming control applied——Depends on material lead time; confirmed in the contractA non-standard substrate, or custom film and lid tooling
5. Mass productionProduction follows the approved sample and specification; in-process control; progress updates shared with you—Progress updates and batch recordsAround 30 days after sample approvalPeak-season capacity; artwork or print rework
6. Pre-shipment & delivery100% inspection before delivery; logistics arranged by sea, air or express; tracking providedRelease to shipInspection record, document pack, tracking informationSet in the quotationDocuments incomplete, or a missed booking cut-off

Timings shown in bold are the ones we publish. Where a stage depends on your specification or on material lead time, the figure is fixed in the quotation rather than estimated here — see our note on why we do not publish rates and lead times as fixed figures.

What happens when a check fails

A check that cannot fail is not a check. When something does not meet the specification, the sequence is:

  1. The batch is held. Nothing leaves the plant while a non-conformance is open.
  2. The non-conformance is recorded against the batch record, naming the material or process step responsible.
  3. The cause is investigated — incoming material, a line setting, or packaging — rather than the symptom being reworked away.
  4. A corrective action is applied and the batch is re-checked before it can be released.
  5. Retained samples make the comparison possible, so the re-check is against the physical product, not a description of it.
  6. If the batch cannot be brought to specification, it is not shipped — and you hear about the delivery impact rather than receiving something that does not match the approved sample.

Where a market requires specific testing or documentation — flushability evidence, or a declaration of plastic content, for example — that requirement is agreed at the specification stage so it is folded into the same batch record rather than bolted on before shipping. For the UK and EU requirements now in force, see our plastic wet wipes ban compliance guide.
