DHL for European countries, the rules for providing tax codes：

IOSS: July 1, 2021 the European Union abolished the tax exemption policy for imports of low value (less than 22 euros), the import scheme created, for goods with a value of up to 150 euros, the introduction of a simplified VAT declaration scheme - Import One-Stop Service (IOSS), sellers need to apply for a separate IOSS VAT identification number. Generally speaking, the value does not exceed 150 Euros and can be cleared quickly with IOSS without the need to provide an EORI number.

VAT number, I believe no one is unfamiliar with the European market, cross-border e-commerce friends know that VAT is commonly used in the EU countries after the sale of value added tax, that is, the profit tax on the sales price of goods. It applies to imports, commercial transactions and services generated in the EU.

The EORI (Economic Operator Registration and Identification) number is a necessary registration number for individuals/businesses that have economic activities between EU countries, especially for import/export trade. So, what is the difference between this EORI and VAT tax number? Both VAT number and EORI number are mandatory for cross-border e-commerce companies to register when they start normal trade in EU countries, EORI number is used for customs clearance of goods, while VAT number is used to pay customs duty, import VAT, and tax declaration for sales VAT.

Moreover, but the value of goods is more than 150 Euros, it is recommended to register VAT number to pay import VAT and customs duty, and EORI number is required.
