Do I have to pay import duty tax for my order?
The VAT is included but the import duty (customs tax) isn’t included, and customer is responsible for paying the import duty if being billed by the local customs.
For EU customers, please check this article.
For US customers, you should not worry about it as US only charges import tax for items over $800, way beyond the value of mechanical keyboards and parts.
For most other regions, if you go with the standard shipping option, the chance of being charged with import duty at customs is extremely low.
The following countries may have high chances of getting taxes and the associated shipping option:
Vietnam (please purchase through Akko VN);
Austria (with FedEx);
Indonesia (with FedEx);
Canada (with UPS);
Colombia (with UPS).
