Corrections

Our policy

Errors are inevitable, and the useful response is a visible one. When we find an error, we:

  1. Correct the page as soon as the error is confirmed, with a dated line in its update log.
  2. Record it here if it changes a material fact, a range or a judgement.
  3. Remove or rewrite the claim if it cannot be supported.

We distinguish a correction (a factual error, a wrong number, a misnamed authority or a broken source), a clarification (accurate but ambiguous wording) and an update (new information, even if the original was right). No page is quietly deleted to avoid a correction.

What counts as a material correction

A correction is material if a reasonable reader could have decided differently had the original been right:

Not material: typos, formatting, a reordered list. Those are fixed but not logged — a log full of comma fixes is a log nobody reads.

What each type looks like

TypeTriggerWhere it appears
CorrectionA fact, figure, name or source was wrongPage edited; dated line in its update log; entry below
ClarificationAccurate but could be misreadPage edited; update-log note; entry below only if it changes a decision
UpdateThe situation changed — a tariff, port rule or servicePage edited; dated update-log entry; relevant country page linked
WithdrawalClaim unsupported, no corrected versionRemoved from navigation; noted here; URL redirected

How a correction is recorded

On the page: a dated line in the update log at the foot of it, saying what changed and why. Where a number or requirement changes, the original wording is quoted so a reader who relied on it can see what they read.

In this log: page, date, type, what was wrong, what it says now, and the source that settled it. The log is append-only: entries are not edited or deleted; a correction to a correction is a new entry.

A worked example

The entry below is real and deliberately small; it shows the shape every entry takes.

An entry that changed a figure would add the old figure, the new one and the source.

How to report an error

Use the contact page. Include the page URL, the sentence and, if possible, the source that shows the error.

Response standards

StageTarget
AcknowledgementWithin five working days
Correction of a confirmed factual errorWithin ten working days of confirmation
Material error affecting a decisionNoted on the page as soon as it is confirmed
Broken or dead source linkReplaced or removed within thirty days
Decision on an appealWithin fifteen working days

These are targets, not guarantees; if a correction takes longer, the log says why.

If you disagree with a correction decision

Either we corrected something that was right, or declined to correct something wrong. The route is the same:

  1. Reply with the sentence and the source you rely on, and say what you think the correct position is.
  2. The source is reopened. Where the point is contestable, a second reviewer who did not make the original call looks at it.
  3. Written decision within fifteen working days: the page changes, or the desk explains why it stands by the original, with its source.
  4. Still disagree? If the objection is substantive, it is published as a short note on the page, attributed as a reader's objection with our response, rather than left in email.

A regulator's or court's ruling on the fact governs. There is no charge, and no way to pay to have a correction removed.

What we do not log

A note on ranges

Most cost and transit figures here are ranges, not point estimates. A range is not a correction target unless it is clearly wrong or unsupported; if it goes stale, the page is updated and the new conditions noted.
