Can You Provide a Sample Testing Report from an Independent Laboratory for Your Stainless Steel Bottles?

When overseas buyers evaluate a stainless steel bottle supplier, they often ask for a sample testing report from an independent laboratory. The request is reasonable, but the wording matters. A sample copy of a report is not the same as a report for your exact model, material, and production batch. For B2B buyers, the goal is to verify that the document matches the product you will receive.

For the OEM 40oz Double Wall Thermal Flask 18/8 Stainless Steel Water Bottles Vacuum Insulated for Outdoor Sports for Boiling Water, model TKH-014-40oz, the published product information states that high-quality material above food grade is used and that relevant test reports can be provided. The product uses 304/201 stainless steel and has a 40oz capacity. Buyers who need an independent laboratory report should confirm the exact model, material, destination market, and test scope with the supplier before ordering.

What the product information confirms

The product page for model TKH-014-40oz provides the following verifiable details:

\n
• Product name: OEM 40oz Double Wall Thermal Flask 18/8 Stainless Steel Water Bottles Vacuum Insulated for Outdoor Sports for Boiling Water
\n
• Model: TKH-014-40oz
\n
• Material: 304/201 stainless steel
\n
• Capacity: 40oz
\n
• Material statement: high-quality material above food grade, with relevant test reports available upon request
\n
• Process controls: seamless stretched cup body or water rising process cup body, automatic environmental protection spray paint and plastic spray line, manual polishing, electrolysis, vacuum pumping for more than 6 hours, and 3 times temperature measurement
\n
• Customization: logo design, packaging design, cup design, and new cup development by a professional design team
\n
• Service experience: more than 10 years of industry experience and one-stop service from production to sales
\n
• Custom logo support from 1 carton
\n

These details are useful because they show what the supplier controls during production. They do not replace a laboratory report. A report verifies specific test results for a specific sample or batch, while the product page describes materials and process controls.

Why a generic sample report is not enough

A laboratory report should be read as a technical document, not as a catalogue page. Before you accept a report, check that it answers all of the following questions:

\n
• Product match: Does the report name the same model, capacity, and construction as the bottle you are buying?
\n
• Material match: Does the sample description match the declared 304/201 stainless steel and the lid or plastic parts in contact with water?
\n
• Test scope: Does the report cover the test items required by your market, customer, or platform?
\n
• Batch and date: Is the report recent enough for your approval process, and does it relate to the production batch or sample you are evaluating?
\n
• Laboratory identity: Is the laboratory name, report number, and test method clearly shown?
\n

If any of these points is missing, ask for clarification. A report that cannot be linked to the product and batch is difficult to use in supplier approval.

Information to include in your request

To get a useful answer, send a short request with the following details:

\n
1. Product model: For example, TKH-014-40oz, or the specific item you are sourcing.
\n
2. Material and parts: Confirm the stainless steel grade and the lid, straw, handle, or coating materials that need to be covered.
\n
3. Destination market: State the country or market so the supplier can confirm the applicable test scope.
\n
4. Required test scope: List the tests your customer, retailer, or platform requires. If you do not have a list, ask the supplier to confirm what relevant reports are available for the model.
\n
5. Order stage: Clarify whether you need a report for a pre-order sample, a trial order, or a mass-production batch.
\n
6. Report format: Confirm whether you need a scanned PDF, a report number for verification, or a specific language.
\n

This request helps avoid a common problem: the buyer receives a report for a different model or an older sample, and the document cannot be used in the approval file.

How Shunfei handles the request

For the OEM 40oz Double Wall Thermal Flask, the published product information states that relevant test reports can be provided for the food-grade material. That statement is the basis for a report request. It does not mean that every possible test or every laboratory is covered by a single generic document.

If your approval process requires a report from an independent laboratory, please state this clearly in your inquiry. Include the model, destination market, and required test scope. The sales team can then confirm whether the relevant report is available for the exact product and order stage. The product information provided here does not name a specific independent laboratory or report number, so those details should be confirmed directly before you place an order.

This is not a weakness in the process. It is normal for B2B supply. Laboratory reports are tied to samples, test methods, and dates. A responsible supplier will confirm the document rather than send an unrelated sample report.

What to review when you receive the report

Use a simple checklist before adding the report to your supplier file:

\n
• Check the report header for the laboratory name and report number.
\n
• Check the sample description against model TKH-014-40oz or the model you ordered.
\n
• Check the material description and the parts covered by the test.
\n
• Check the test method and result against your market requirement.
\n
• Check the report date and whether it applies to the batch or sample you are approving.
\n
• Keep the report together with the purchase order, sample approval, and specification sheet.
\n

If you need verification, ask the supplier for the report number and the contact details of the testing laboratory. Do not rely only on a screenshot or a cropped page.

Quality controls behind the stainless steel bottle

Testing is one part of quality assurance. The product information for model TKH-014-40oz also describes production controls that buyers can discuss during an audit or sample review:

\n
• Seamless stretched cup body or water rising process cup body, depending on the cup shape
\n
• Automatic environmental protection spray paint and plastic spray line
\n
• Manual polishing and electrolysis
\n
• Vacuum pumping for more than 6 hours
\n
• 3 times temperature measurement to support vacuum insulation quality
\n

These process steps help explain how the supplier controls the cup body, coating, finish, and vacuum performance. They are also good topics for a factory audit. Ask how each step is recorded and how non-conforming units are separated.
