Shipping Information


Please note that due to the current COVID-19 pandemic we are experiencing delays in our delivery times. Your order will be shipped ASAP, usually within 48 hours. Once the package has been handed over to the courier, we also depend on their services. The courier services are doing their absolute utmost to deliver the item within the agreed time, but Covid-19 regulations and the sudden increase of shipments can result in a delay of occasionally up to 10 days. We apologize for this inconvenience, and we hope for your understanding. In case of any questions on the shipment of your order, please do contact us and we will help you to the best of our abilities. 

Thank you for understanding!
Sigma lets you enjoy free shipping worldwide on all orders. Please allow up to 6 business for your order to be processed once the payment is received and cleared. Your package will take between 7 and 14 working days on average to arrive, depending ont the courier services available in your area.

All orders are shipped DDU, which means "duties and taxes unpaid" from our warehouse in Asia. In this case we do not collect VAT, duties and/or taxes and cannot predict what you estimated charge may be. In order to collect your package, additional charge must be paid to clear customs. As we ship to over 40 countries, some may require additional fees paid COD (Collect On Delivery). In this case, the fees are paid to the local carrier.
