Canadian customers pay GST/HST that are automatically calculated at checkout once you fill out your shipping address. All taxes are collected upon placing the order. No customs & duties will apply to your shipment.
USA customers may not need to pay sales taxes based on which state you are in. Customs & duties may apply in extremely rare situations.
International customers may need to pay import duties and local taxes and will be charged by the third-party carrier once your order arrives. The charges are to be covered by the customer. The threshold of import duties varies from country to country and Kidamento is not able to give you legal advice. It might be a good idea to contact your local customs office for current charges before you place your order.
