Coverage and gaps

This page says what CarryRules covers and, more usefully, what it does not. A reference that only advertises its strengths is hard to trust, so the gaps are listed here by name.

What is covered

The figures below are generated from the published data set, not typed by hand, so they change when the data does.

Known gaps

These are country and item pairs where no authority we can reach publishes a rule, and we have declined to invent one. Each carries the reason it is empty.

Why a cell stays empty

Three reasons, in order of how often they occur:

• The authority publishes nothing about it. Most empty cells are this. No dangerous-dog breed list exists in the United States, Italy or Thailand; Thailand publishes no allowance tiers by length of absence; the United States restricts importing cultural property but imposes no general export licence on travellers. Publishing a number here would mean making one up.
• The item is named in another country's language. The catalogue carries some items under the wording of the country that regulates them. Where another country has no counterpart, the cell stays empty rather than borrowing a foreign rule.
• The source cannot be reached. A handful of authorities refuse automated access, sit behind a bot check, or are down. These are retried rather than filled in.

Outside the scope

CarryRules covers what a traveller carries. It does not cover commercial import, freight, customs valuation and duty calculation for goods in trade, visa and immigration rules, or the tax refund schemes that travellers often confuse with duty-free allowances. Where a limit exists only for commercial consignments, the rule says so instead of presenting it as a traveller's limit.
