Data changelog — how WorldFreightHub data is updated

This page records when WorldFreightHub data and content changed, and how each data type is kept current. The entries are drawn from the site's commit history and data-layer review dates.

Data update principles

Data update cadence

  • Duty / VAT / compliance rules: Monthly review against ZATCA, Dubai Customs, SASO and other primary sources.
  • Freight rates / transit times: Indicative ranges refreshed with the monthly review, not live quotes.
  • Port / route profiles: Quarterly review.
  • Provider directory: Rolling verification, with a recorded lastVerified date.

Cadence describes the review cycle, not a guarantee that a source changed on that date. When a primary source changes earlier, the page is updated to match.

Changelog

  1. Freight quote database — data infrastructure (P0–P2)

    • Launched the freight quote database: 24 indicative freight forwarder quotes (16 Middle East + 8 Europe), published 2026-09-22.
    • Single Source of Truth: homepage counts (routes, ports, providers, guides, glossary) now derived from data files at build time.
    • Quote model extended: basis, confidence, verified, carrier, transit mode and route fields; existing records backfilled (default assumptions marked "待货代确认").
    • Entity IDs: stable identifiers for countries (ISO2), ports (UN/LOCODE), routes (origin–destination LOCODE), providers (WH-P-###) and rates (RATE-YYYYMMDD-###) wired into page JSON-LD.
    • Quote Intelligence: per-equipment statistics (records, latest, 30/90-day ranges, median) on route pages — computed from stored records only.
    • Machine-readable export: /data/freight-quotes.json (CC BY 4.0).
