Methodology

How we structure and review trade information

Our method keeps classification, evidence, dates and uncertainty beside each conclusion.

Four core principles

  1. Classify before concluding.Product facts come before precise rules or rates.
  2. Keep sources beside claims.Important requirements link to primary evidence.
  3. Show uncertainty.Confidence, assumptions and missing details remain visible.
  4. Preserve history.Changed and superseded records remain traceable.

Review workflow

We identify the authority, capture the official source, structure the rule, connect it to products and routes, review the wording, then publish it with a status and date.
