Customs Duties & Taxes
All prices exclude taxes. Customers are responsible for all duties and taxes. RBDIMMER is not responsible for any additional costs after shipping the original package.
If you refuse to pay taxes, the return shipping cost and any additional fees will be deducted from your order total, and the remaining balance will be refunded.
For European customers: Orders are shipped through the "Green Channel," meaning customs fees are not usually required. However, if you need a VAT invoice, you may need to contact your local customs or tax office. We provide an invoice for your order upon request.
