New EU Tax per Harmonised Tariff Code

On July 1st 2026, the EU will introduce a flat fee of 3 Euros for each harmonised tariff code noted in an order imported into the Eurozone. The fee is not based per product, nor per quantity, but upon the category of product . Within Woocommerce, the simplest way of managing this new charge would be to apply a flat fee for each shipping class, with each class being a distinct Harmonised Tariff Code. For example, books are 49019900, playing cards are 95044000, etc. There are several mechanisms that assist B2C imports to the EU, notable the DDP, or IOSS systems. But I can find no plug-in that permits a flat fee per shipping class that can be applied to select countries. Given this requirement will affect all Woocommerce store owners who ship into the EU, I was hoping someone could recommend a simple solution. Hi @robertshehuansell Thanks for the detailed explanation of the requirement. I understand the use case: from July 1st 2026, you need to apply a €3 flat fee per harmonised tariff code (mapped via shipping class) for orders shipped into EU countries, where the fee should apply per class/category rather than per product or quantity. In WooCommerce core, there isn’t a built-in feature that can apply a flat fee per shipping class as a grouped per-class charge across the entire cart in this specific way, especially with country-specific conditions like EU-only application. A small customization can be added to calculate a €3 fee per unique shipping class (tariff code) in the cart and apply it only for EU shipping zones. If you need more in-depth support or want to consider professional assistance for customization, I can recommend WooExperts and Codeable.io as options for getting professional help. Alternatively, you can also ask your development questions in the WooCommerce Community Slack as custom code falls outside our usual scope of support . Thank you for cooperation and understanding.
