Due to the customs regulations, you need to make sure all orders to Brazil, Korea or Chile contain additional customs clearance information in Customer Detail as below. Otherwise, the orders cannot be placed to your suppliers.
| Country | Required Tax ID Type |
|---|---|
| Brazil | CPF |
| Chile | RUT |
| South Korea | CCI (Customs Clearance Information) |
| Turkey | Turkish ID Number |
| Israel | Identity Number |
| Mexico | RFC / CURP |
| Peru | RUC |
| Oman | RUC / Omani Tax ID |
| Argentina | CUIL / CUIT |
⚠️ Critical for Brazil & South Korea: For these two countries, the tax ID alone isn't enough—the customer's name must match the tax ID exactly, so customers need to provide their full legal name at checkout.
