How this database is built
Methodology
Every number on this site is traceable to a primary source. Here is exactly how it gets here — and what we will never publish.
Sources
All fee data comes from carriers' published rules tariffs and accessorial schedules — the public documents each carrier posts (e.g. FXF 100 Series, CNWY 199, ODFL 100-series, EXLA 105). We record the document name, item number, page, a short verbatim quote, and the version's effective date for every row. We never use blog estimates, quote-tool outputs, or industry "typical ranges" as data.
Extraction and verification
Fees are extracted from tariff PDFs with AI assistance, then every row is verified by a human against the cited page before it is published. Unverified rows never appear on the site or in the sitemap.
Change tracking
When a source document changes (a GRI or mid-year tariff revision), we don't overwrite history — the prior value is retained with its effective window, and the change appears in Updates. Pages show both the source's effective date and the date we last verified it.
What we deliberately exclude
NMFC freight classification data — classes, item numbers, and commodity tables — is licensed by the NMFTA and is not republished here in any form. We document reclassification fees; never classification data itself.
Corrections
Spot an error? Email tyler@thegoodstudio.io with the page and the source you're looking at — corrections ship in the next publish cycle.
