Can I travel by air with a meteorite?
Usually yes, but rules vary. Meteorites are not generally dangerous goods, but customs and export laws apply, and some countries restrict or ban export.
Meteorites are rocks, and in most cases they can travel by air in luggage. However, several considerations apply.
Security screening. Dense iron meteorites may attract attention at airport security because they show up clearly on X-ray scanners. Carry documentation, such as the specimen's label or certificate, and be ready to explain what it is. Heavy items count towards baggage weight limits.
Customs and declarations. When entering or leaving a country, you may need to declare items of value or natural specimens. Some countries require paperwork for geological specimens. Check customs rules before travelling.
Export laws. Several countries regard meteorites as national heritage or state property, and exporting them without permission is illegal. Taking a meteorite found or bought in such a country out without a permit can result in confiscation or prosecution. This applies to meteorites found in some deserts, as well as to protected falls. Always check the law of the country you are leaving.
Import rules. Some countries have rules about importing soil or rocks, mainly for biosecurity, so clean specimens of soil before travel.
Packaging. Wrap meteorites carefully to protect them, especially thin slices and fragile stones. Place small specimens in padded boxes or bags with desiccant.
Valuable specimens. For valuable items, consider carrying them in hand luggage, keeping receipts and documentation, and checking insurance coverage.
Rules change, so check the current regulations of airlines, origin and destination countries before travelling with meteorites.
