## Meaning and scope

A **quote validity period** defines how long the offer remains current for the items and scope stated. Check the item-level expiry and keep it separate from order confirmation and delivery. [MISUMI UK terms](https://uk.misumi-ec.com/en/legal-notice/terms-and-conditions/) · [Xometry customer service agreement](https://www.xometry.com/service-agreement/).

## Supplier quotation examples

| Source and applicability | What its validity language covers | Separate condition |
| --- | --- | --- |
| [Proto Labs, Inc. (Minnesota), Protoquote terms](https://www.protolabs.com/legal-notices/protoquote/) | Quotes are valid for 30 days; pricing may change afterward. | A change to the submitted 3D CAD model requires an updated quote. The source also reserves correction of clerical and typographical errors. |
| [MISUMI Europa GmbH, UK-site quotation FAQ](https://uk.misumi-ec.com/en/services/faq-and-tutorials/details/how-long-are-misumi-quotations-valid/) | Quotations are valid for four weeks from issue, with a validity date shown for each item. | Items sourced separately, large quantities or supplier special conditions may have a shorter period shown on the quotation or order confirmation. |

These are supplier-specific examples, not standard periods for manufacturing quotations. Protolabs' clause says *pricing may change* after 30 days; it does not say every price automatically changes on day 31. MISUMI's item-level dates mean that a single document may contain different effective deadlines. [Protolabs' terms](https://www.protolabs.com/legal-notices/protoquote/) and the [MISUMI FAQ](https://uk.misumi-ec.com/en/services/faq-and-tutorials/details/how-long-are-misumi-quotations-valid/) support those narrower readings.

**Validity is separate from order and delivery status.** Under the UK site's [MISUMI Europa GmbH terms, §§3.11 and 7.1](https://uk.misumi-ec.com/en/legal-notice/terms-and-conditions/), requested price information or a quotation is subject to confirmation, and the delivery period begins with the sending of the order confirmation, subject to specified documents, approvals and any agreed advance payment. Its broader offer clause, §3.1, expressly excepts offers marked binding or containing an acceptance deadline from its general subject-to-confirmation wording. [Xometry, Inc.'s customer service agreement, §3.1](https://www.xometry.com/service-agreement/) says its manufacturing contract does not exist until Xometry acknowledges the customer's quote acceptance. Neither supplier's wording makes a displayed validity date a general promise of stock, production capacity or delivery timing.

**Revisions and withdrawal depend on the source.** Protolabs requires an updated quote after a change to the submitted 3D CAD model. [Xometry's agreement, §3.3](https://www.xometry.com/service-agreement/) permits revocation or cancellation during quotation, ordering or manufacturing for technical or other reasons, with reimbursement of money paid for the affected part. These clauses have different scopes; a revision, withdrawal right or firm-price commitment cannot be inferred from the word “valid” alone.

## Public sealed-bid context

The quoted **issue date**, **acceptance deadline**, **order date**, **seller confirmation** and **delivery date** are different events. A duration alone does not resolve a date-only deadline's cutoff time, time zone, treatment of weekends, or whether an item has its own earlier expiry. Those details depend on the wording of the particular document. In contrast, the US federal sealed-bid provision [FAR 52.214-16](https://www.acquisition.gov/far/52.214-16) expressly measures its acceptance period in *calendar days* from the solicitation's specified bid-receipt date; that rule is confined to invitations for bids containing the provision.

An invitation-for-bids **bid acceptance period** is a distinct procurement convention. [FAR 52.214-15](https://www.acquisition.gov/far/52.214-15) says that, when that provision is included, the bidder agrees to furnish bid items at the stated prices if the bid is accepted within the inserted number of calendar days from the solicitation's specified bid-receipt date; its form supplies 60 calendar days unless the bidder inserts another period. [FAR 52.214-16](https://www.acquisition.gov/far/52.214-16) instead supplies a government-set minimum and permits a longer bidder-entered period; it rejects a shorter one. Under [FAR 14.201-6(i)–(j)](https://www.acquisition.gov/far/14.201-6), §52.214-15 is prescribed for IFBs not issued on SF 33 or SF 1447, except construction IFBs and those specifying a government minimum. Section 52.214-16 is prescribed for nonconstruction IFBs when the contracting officer determines a minimum is needed. Neither provision establishes a default for private quotations.

The bid-submission cutoff also differs from the later acceptance period. In solicitations containing [FAR 52.214-7](https://www.acquisition.gov/far/52.214-7), a bidder may withdraw by written notice received before the exact bid-receipt time, subject to that provision's methods and conditions. This does not establish a general right to withdraw a private supplier quote after issue.

## Coverage limits

The supplier examples apply to the named entities and cited pages, rather than every regional affiliate or customer agreement. [Xometry's page](https://www.xometry.com/service-agreement/) displayed **Last Updated: July 28, 2026**; the [MISUMI UK-site GTCs](https://uk.misumi-ec.com/en/legal-notice/terms-and-conditions/) displayed **Status: 29 May 2026**. The cited [Protolabs page](https://www.protolabs.com/legal-notices/protoquote/) and [MISUMI FAQ](https://uk.misumi-ec.com/en/services/faq-and-tutorials/details/how-long-are-misumi-quotations-valid/) supplied no separate revision date for these clauses. The cited FAR pages displayed **FAC 2026-01, effective March 13, 2026**; §§52.214-15 and 52.214-16 carry April 1984 provision dates, while §52.214-7 carries November 1999. Those provision dates and the displayed FAR compilation version describe different things. [FAR 52.214-15](https://www.acquisition.gov/far/52.214-15), [52.214-16](https://www.acquisition.gov/far/52.214-16), [52.214-7](https://www.acquisition.gov/far/52.214-7)

Source review on **October 30, 2026 PDT** included directly retrieved supplier HTML. MISUMI access varied: earlier requests returned HTTP 403, and search-service opens timed out; official indexed FAQ and terms text corroborated the clauses, but cached text alone cannot establish a current version. The final direct retrieval succeeded, including the four-week FAQ and dated GTCs. Linked PDFs were not examined, and their contents or editions are not established here.

This reference does not determine which terms govern a particular exchange, whether a quote was accepted, the effect of an expired quote, or the legal enforceability of any clause. Those questions depend on the actual quote, incorporated terms, communications and applicable law.
