Once your order has been processed and prepared for shipment, you will receive a confirmation email that your order has been dispatched. Please allow up to two business days for your order to be processed and to receive the shipping confirmation email, which will contain tracking information for your order. Please make sure your shipping address is correct as we are unable to redirect goods once they are en route to you. 

Delivery times vary according to the shipping destination. 

Malaysia: Orders will arrive within three business days of dispatch.

Asia Pacific: Orders will arrive within five business days of dispatch. 

Rest of the World:  Orders will arrive within five to ten business days of dispatch.

We use tracked courier shipping for all orders.

Note: When international orders arrive in destination countries, there is a possibility that customs clearance procedures may cause delays, which are beyond Dia or our logistic partners’ control.

You may track your order using the tracking information provided in the shipping confirmation email.

Dia ships on a Delivered Duty Unpaid (DDU) basis. This means you may be charged for customs duties and import taxes on your order, which Dia has no control over, as these policies vary widely from country to country. If customs duties and import taxes arise, they must be paid by the person receiving the parcel. 

However, please note that import taxes are only charged if certain thresholds are met. For example, in the United States, you do not need to pay import taxes if your purchase value is less than $800. And in Hong Kong, for instance, there are no import taxes.

Returns & Refunds

Dia cares deeply about whether or not our customers are satisfied. If for some reason you are not pleased with your order, we accept returns of unused and undamaged items within seven days of receipt.

All returned items must be accompanied by original packaging, such as boxes, tags and any protective materials. We reserve the right to refuse merchandise if an item is not returned in its original condition, including all packaging and tags.

All qualifying and accepted returns will be refunded. If you wish to exchange an item for a different size, we will aim to expedite your refund so you are able to purchase the new item, subject to stock availability.
