A quotation for EVA foam color matching usually rests on one physical reference: a sprayed board, a previous production lot, or a sample you mailed us. When that reference is replaced after the price is issued — a new swatch, a corrected target shade, a second supplier's lot — the quotation no longer describes the job we are being asked to run. A revision notice is how both sides put the change on record before tooling and printing plates move ahead.

Why a late swatch swap moves more than the foam

Our EVA foam takes its color in one-step foaming with added color masterbatch, so the shade is set inside the material rather than painted on afterwards. Changing the target therefore changes the raw material mix, and with it the input cost that sat behind the original figure. It also affects everything layered on top: a printed design that read well against the first shade may need a different white-base pass to keep saturation, and screen-printing plates carry ink-film assumptions you do not want to discover at press.

None of this is a problem if the change arrives as a written notice while the job is still in design and tooling. It becomes expensive when it reaches us after mold opening and printing molding has started.

The seven items a revision notice should carry

A short, structured email saves more time than a long one. Include:

• The quotation number and date — name the document being amended, so nobody works from an old PDF.
• What is being replaced and what replaces it — the outgoing reference (sample code, lot, or physical swatch you received back) and the incoming one, with its tracking number.
• The reason for the change — brand guideline ｕｐｄａｔｅ, retail line-up alignment, or a mismatch found in your own incoming inspection. The reason tells us which part of the build to re-check.
• The affected items and quantities — which SKUs, sizes and order volumes carry the new shade, and whether earlier lots stay on the old one.
• The acceptance method — who signs off the matched color, against which reference, and where the tolerance sits between your approved sample and mass production.
• The destination market — tell us the country you are shipping to, and we will recommend raw materials that meet the corresponding national standards for that market.
• The date you need confirmation by — plate-making takes five to seven days and bulk orders can be delivered within fifteen, so the notice needs a deadline attached.

What we send back, and what you should check on it

On receipt of the notice we re-issue the quotation with the amended color reference written into it, and state plainly which costs move: masterbatch and raw material, print plates where the artwork changes, and any re-foaming of already prepared sheets. If your change touches a printed design as well as the foam shade, our team reviews the artwork and flags linework or coverage that will not hold on the new base color.

Check three things before you sign the revised sheet. First, that the reference quoted matches the swatch now in your own hands, not the one you sent months ago. Second, that the sample stage is still ahead of you — on our custom bath puzzle and educational toy lines, samples take five to seven working days and production runs after sample confirmation, so a signed revision before that point costs nothing but time on paper. Third, that the inspection clause names the same reference you approved.

How the change is verified before containers move

Color sits inside a defined test set rather than being judged at the end. Production runs pass through sixteen types of tests, including color fastness and ink material environmental-protection testing, with full manual inspection before shipment and defective items rejected outright. We support 100% third-party inspection, and buyers are welcome to run their own factory audit.

If your buyer has already approved a physical signed sample, keep that sample. It is the document that ends an argument about shade; a scanned swatch or a screen proof does not.

A short revision notice you can copy

Subject: Revision to Quotation [number], dated [date] — color reference change, PO [number]

Reference being replaced: [outgoing swatch or sample code]. New reference: [incoming swatch, dispatch tracking number, arrival date]. Reason: [brand ｕｐｄａｔｅ / line-up alignment / inspection mismatch]. Affected items and quantities: [SKU, size, quantity]. Unaffected items: [list]. Acceptance: color approved against [reference] by [name], tolerance as agreed on signed sample [code]. Destination market: [country]. Please confirm revised pricing and revised lead time by [date]; tooling status on our side is [drawing / plate-making / mold opening].

Bringing the change to us

Send the notice with the physical reference in the same post, and we will confirm pricing and schedule against it. As a custom EVA foam manufacturing partner working from customer drawings and samples, we would rather see the change on paper in week three than hear about it at pre-shipment inspection.
