I’ve received a lot of great advice from backers about international shipping and I've been working with outside counsel and experienced retailers to make the process as simple as possible.
To ensure that I am compliant with U.S. customs regulations, I will be checking the box marked "Other" on the customs form and putting Kickstarter Pledge Reward in the box. I know that some of you have asked that I check the gift box, but I've been advised by outside professionals that "Other" is more accurate.
As for import regulations, the range of rules that may apply to the mini museum across the globe is daunting. There's really no way I could review all of these rules for every country.
However, I will declare the mini museum under harmonized tariff code HS 9023.00.00. This is the code used for "Instruments, apparatus and models, designed for demonstrational purposes (for example, in education or exhibitions), unsuitable for other uses, and parts and accessories thereof". Please note that this is not a guarantee in any way. Backers should be aware of regulations in their own countries.
As always, keep an eye on project updates for the latest information on international shipping. https://www.kickstarter.com/projects/2054592112/mini-museum/posts
