Rate validity

Rate validity is the time dimension of a price. A spot quote is valid until the pickup date or until the carrier says otherwise; an awarded rate is valid for the term of the bid, typically a year, unless a trigger reopens it. The triggers are the important part: fuel moving past a band, the peso moving past a band, actual volume falling well short of forecast, or a change in crossing. A rate with a stated term but no triggers is a rate that one side will stop honoring when the market moves.

Cross-border validity expectations often differ: some Mexican carriers quote for a season and expect to renegotiate when conditions change, while U.S. procurement expects the rate to hold as written. Neither side is wrong; the gap has to be written down.

What this means when you move freight

Put the validity period and its triggers in the rate confirmation and the award letter, in both languages when the carrier operates in Spanish. Brokers should quote a validity window they can actually hold on the Mexican leg, and say what reopens it, rather than absorbing a peso move for months and then rejecting tenders. Shippers should compare the awarded rate against the market rate at each trigger point rather than waiting for the term to end, because a rate that has drifted far from the market will be reopened by tender rejections whether the paperwork allows it or not.
