Additional Tips for Non-US Customers Returning Items to the US: Please note that the declared value of your shipment should be equal to the original selling price of the item(s) at the time of purchase. The shipment should be sent DDP (Incoterms 2010) with the customer being responsible for all importation fees and documentation unless a UPS return label has been provided to you by a member of the Thorlabs team. Please indicate the reason for the return on the customs invoice used to send back the items: Return of previously exported goods, Return for Replacement of previously exported goods, or Return for Repair of previously exported goods, to be re-exported upon completion of repair. Thorlabs Inc. will not be responsible for customs fees, taxes, duties or other fees levied as a result of improper labeling or documentation. In such instances, we will add fees incurred to your invoice or will bill separately.
