A buyer searching for Thermos is usually trying to stop a bad substitute. A kitchen tool or vessel is specified by food contact, heat, size, and how it will be washed. The notes below are selection criteria for a Thermos. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Thermos
A kitchen tool or vessel is specified by food contact, heat, size, and how it will be washed. For a Thermos, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Thermos is easy to confuse with Tablecloth. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Thermos |
|---|---|
| Food contact | The material that touches food, and a food-contact statement. |
| Heat | Maximum temperature, hob type, or dishwasher limits. |
| Size | Diameter, volume, or blade length. |
| Handle and safety | Stay-cool handles, and a guard where there is a blade. |
| Coating | What the nonstick coat is, and whether it is essential or optional. |
| Care | Dishwasher, oven, and metal-utensil limits. |
How to compare two offers
Lay both quotes for Thermos on one sheet and line up food contact, heat, and size. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Thermos with a cheaper line that omitted food contact.
Documents worth having before the deposit
Ask for the food-contact material rather than a marketing finish name. The file should name Thermos and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Ignoring induction compatibility.
- Leaving blade steel and hardness off a knife order.
- Buying a coating that cannot see the dishwasher you own.
On a Thermos, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Thermos — State food-contact material, heat limit, size, and washing method.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like RoHS / CE belong
Searches often add a constraint to Thermos: RoHS / CE, or waterproof / IP65. Keep those on this page. RoHS is a material limit. CE is a declaration that lists the rules relied on. Ask for the document that names this part number and revision. IP65 in IEC 60529 means dust-tight and protected against water jets. Write that code if hoses are the real exposure. The word waterproof alone does not name a test. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Thermos include?
State food-contact material, heat limit, size, and washing method.
Is a cheaper Thermos the same part?
Only if food contact, heat, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Thermos they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
