Translate a broad claim into a defined requirement
Fluorescent-free can be used imprecisely: a buyer may mean no intentionally added optical brightener, no specified substance above an agreed limit, or no visible response under a particular examination. Those are different requirements. Ask what is being claimed and how it will be assessed.
Likewise, food grade is not a universal pass that follows from the word microfiber. Identify whether the cloth is intended to touch food directly, contact a food-contact surface during cleaning, or serve a different task. The product and use route determine the evidence question.
Why a torch demonstration is not a complete safety assessment
Appearance under a light source depends on the source, material, colour and observation conditions. A visible response does not identify every chemical present, and no visible response does not prove the absence of all relevant substances.
Use any visual screen for the limited question it can answer. If a buyer requires a substance limit or a particular claim, agree a suitable method and reporting limit with the relevant laboratory or adviser. Do not replace chemical identification with a photograph of a glowing cloth.
Define food-contact scope before requesting a report
The European Commission’s food-contact materials overview explains the framework for materials and articles intended to contact food. It is a starting point for determining requirements, not a product approval or a statement that every cleaning cloth has the same obligations.
For the actual item, specify contact type, food or surface, temperature, duration, repeated use and any cleaning steps. Ask a competent laboratory or destination-market adviser which requirements apply. Do not copy a test package from unrelated packaging or another textile.
Check the specimen, not only the laboratory name
Match the report’s sample description, composition, colour, printing or finish and date to the proposed product. Read what was tested and under which conditions. A laboratory logo alone does not show that a report covers the finished retail item or the buyer’s intended claim.
If an item changes, review whether the evidence still applies. A new dye, print, finish or backing can create a different question. Keep the supplier declaration and the supporting report connected to the approved sample revision.
| Claim or question | Define first | Do not use as sole proof |
|---|---|---|
| No optical brightener | Substance/meaning, method and limit | A UV photograph alone |
| Food-contact suitability | Item, contact conditions and destination | A generic fibre declaration |
| Colour or finish change | Revised specimen and evidence scope | A report for an unconnected sample |
| Material safety wording | Exact intended claim and applicable requirements | A supplier logo or unspecified safe label |
Prepare a claim-approval record
Start from a named SKU such as SM21001 to identify the catalogue proposal, then record the requested claim separately. The catalogue composition and dimensions are sourcing references; they are not the safety evidence discussed above.
Before printing the claim, collect the intended-use description, applicable requirement, specimen identity, method, result and label wording review. If evidence is pending, keep the claim pending rather than treating missing information as a pass.
