Applicable taxes may be charged in your home country
  •  What is it?
A tax levied on imports by the customs authorities of a country to raise state revenue, and/or to protect domestic industries from more efficient or predatory competitors from abroad.
Customs duty is based generally on the value of goods or upon the weight, dimensions, or some other criteria of the item.

Please note that:
If you live outside of the USA or Europe you may be subject to this tax.
This tax is not charged by My Social Book or by the carrier, but by your local customs authority.
 
  •  Why should I pay it?
You may be charged customs duties and taxes for something purchased online because:

- Duties and taxes are most typically not included in the price of the goods you purchase online, and might not be included in the overall shipping costs you pay to the online retailer.
- When purchasing goods online, some or all of these goods may not originate in the country you reside in, therefore are subject to a customs duty, which is a tariff or tax imposed on goods when transported across international borders.
- When goods are not shipped domestically (within your country) or within a single customs union, such as the European Union, you are liable to pay any inbound duties and taxes which your local customs authority deems appropriate.
