Put these on the RFQ for Dry Bag before you compare prices.

A buyer searching for Dry Bag is usually trying to stop a bad substitute. A bag is specified by volume, the load, the fabric, and the hardware that fails first. The notes below are selection criteria for a Dry Bag. 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 Dry Bag

A bag is specified by volume, the load, the fabric, and the hardware that fails first. For a Dry Bag, 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.

Dry Bag is easy to confuse with Shopping Bag. 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 Dry Bag
Load Carry weight and the strap or handle that takes it.
Hardware Zipper, buckle, and wheel rating.
Compartments The organization the user actually needs.
Branding Logo method and the artwork revision.
Volume and fit Liters, or the laptop and contents it must hold.
Fabric Denier or material, and a water claim only if a test is named.

How to compare two offers

Lay both quotes for Dry Bag on one sheet and line up load, hardware, and compartments. 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 Dry Bag with a cheaper line that omitted load.

Documents worth having before the deposit

Ask for a bill of materials for fabric and hardware. The file should name Dry Bag 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 zipper cycles on a daily bag.
  • Specifying liters and forgetting the laptop sleeve dimensions.
  • Using an untested waterproof word on a fashion shell.

On a Dry Bag, 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: “Dry Bag — Write volume, load, fabric, hardware, and logo 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 OEM / custom belong

Searches often add a constraint to Dry Bag: OEM / custom, or automotive grade. Keep those on this page. OEM or custom means a drawing, a revision, and a statement of who owns the tool. Without those, you are buying the catalog part. Automotive grade is a temperature, vibration, and documentation claim. Ask which AEC or customer spec is actually met, and for which part number. 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 Dry Bag include?

Write volume, load, fabric, hardware, and logo method.

Is a cheaper Dry Bag the same part?

Only if load, hardware, and the documents match. A missing line is a different offer.

Do waterproof, OEM, or IP words need their own page?

No. For Dry Bag they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
