There are no customs fees if your shipping address is in the USA, Canada*, Europe, UK, Australia or New Zealand. We partner with print labs all over the world to produce your custom Star Map print locally so they don't won't have to go through customs.
If your order is going to a country in the rest of the world, import tax fees may be required depending on the country's customs laws. Such countries can be in Central America, Latin America, Asia and the Middle East. Since this depends on the laws of the country of destination, we suggest getting in touch with your local customs agency should you need further information.
Canada*: in most cases, our customers in Canada will have their prints made in Canada. In some cases, e.g. for framed prints, they are made in our labs in the US or the UK and may require customs fees. Please contact firstname.lastname@example.org if you need help sorting this out.
