Quality & documentation
Test Reports & Product Documents
A buyer's document pack is several documents, each proving something different. Knowing which one answers which question, and what each one covers, stops a report for one configuration being relied on for another.
What each document proves
| Document | What it establishes | Issued by |
|---|---|---|
| Mill certificate | The chemical composition and grade of a steel lot. | The steel mill, for the coil used. |
| Material declaration | Which materials and grades each component is made from. | The manufacturer. |
| Test report | Results of specific tests on a specific sample, for example migration or metals release. | An accredited laboratory. |
| Declaration of compliance | That the product meets named regulations under stated conditions of use. | The business responsible for the product, supported by test reports. |
| Inspection report | Workmanship, quantity and pack-out of a production lot, against an agreed plan. | The factory or a third-party inspector. |
| Packing list and invoice | Quantities, cartons, weights and values for customs. | The exporter. |
A company management-system certificate, such as ISO 9001, describes how a business is run. It is not a product test report and does not show that a particular product meets a food-contact rule.
How to read a report's scope
Before relying on a report, check that it covers what you are selling:
- The named entity and the sample identification match your product and supplier.
- Every component in the contact path is covered, not just the main body.
- The test conditions match your intended use: food type, temperature and contact time.
- The date and regulation version are current enough for your buyer.
- Any change since the test, such as a new colour or supplier, has been assessed.
Marking, traceability and import records
Documentation has to connect to physical goods. A batch or date code on the product or carton, recorded against the production run and its material certificates, lets you trace a complaint to one lot rather than withdrawing everything.
Country-of-origin marking is a legal requirement in several markets. In the United States, 19 CFR 134.11 requires that "every article of foreign origin (or its container) imported into the United States shall be marked in a conspicuous place as legibly, indelibly, and permanently as the nature of the article (or container) will permit". Decide the marking method at the specification stage, because it affects tooling and artwork.
Requesting documents
Email info@kovatough.com with the product, the documents your buyer requires and the destination market. We confirm what exists for that configuration, what needs commissioning and how long it takes, and keep every document linked to the same product reference and sample version.
- The product reference and sample version, or a drawing number and revision.
- Every component that touches food, with its material: stainless grade, polymer, silicone, wood, coating or decoration.
- The foods it will meet and the conditions: temperature, contact time, repeated or single use, dishwasher or hand wash.
- The country of sale and the sales channel, plus your buyer's document checklist if they have one.
- Whether the request covers the current configuration or a proposed change.
