    Do you charge tax on my order?

    Our prices are exclusive of VAT (Value Added Tax):

    Non-UK Customers: We do not charge tax on your purchase. You are liable for paying all applicable taxes and import duties in your destination country. If you have a taxation or customs reference number please provide this on your Purchase Order or at checkout to facilitate easier customs clearance. For EU Customers, this is your EORI or VAT number.

    UK customers: Most academic institutions in the UK are qualified for zero rate VAT (commonly referred to as VAT exemption). If this applies to you, please select "Yes" for the question "I am tax exempt" during the check out process. You will then be asked to upload your VAT exemption, or state that it's included in your PO, or email it to us later. We will add 20% VAT to your invoice if no certificate is received or if your institution does not have VAT exemption.

    US customers: If you are a non tax-exempt customer purchasing in the states of Missouri or North Carolina, you are subject to their sales tax.

    Can I place the order in my home currency?

    You can choose the currency by selecting your country on the top right corner of the page. Once you select your country, the currency will be changed accordingly.

    Our products are priced in three currencies: Great British Pound (GBP, £), EURO (EUR, €), and US Dollar (USD, $). You can choose the currency by selecting your country on the top right corner of the page. Once you select your country, the currency will be changed accordingly.

    How will I know if my order has been received or dispatched by you?

    We send order confirmations by email or fax for all orders. Please contact us if you do not receive an order confirmation from us. We can send the order confirmation to two email addresses, one for the billing/purchase department and shipping. If your purchasing department places the order for you and you would like to receive order confirmation, please ask them to put your email address on the purchase order.

    Returns and Cancellations

    How do I cancel my order?

    Before an order is dispatched, if the customer wishes to cancel the order, they must notify Biorbyt. There will be no cost to the customer if cancellation is less than 24 hours after order confirmation. If the customer wishes to cancel an order 24 hours after receipt of the order confirmation, a restocking fee of 25% of the goods' total price will apply. After the product is dispatched, the customer cannot cancel the order, but they may return the product. Please see below for guidance on returning products.

    How do I return the products?

    If products are ordered incorrectly by the customer, we will consider taking them back. However, this excludes products with special shipping requirements, including those shipped on dry ice and those hazardous for transport. All requests for returns must have prior authorization and must be shipped back to Biorbyt within seven working days of receipt of products. The products must have been kept in the storage condition as stated on the datasheet and not opened, broken, or otherwise altered. Items must be returned in the same or equivalent packaging (i.e., cold and insulated) as originally dispatched by us. You will need to send the products back to us using your own shipping company and are responsible for any imposed customs or taxes that might be incurred. Please note we charge 25% of the total product price for restocking. Shipping and handling charges are not refundable.

    How do I claim a refund for my order?

    We are proud of the quality of our products. However, if the product does not perform as described on the datasheet, we will provide a replacement or refund. Please note that shipping, handling, and packaging charges are not refundable. You will need to provide us with your protocol for us to examine and results illustrating the issue - you can also provide more information about your issue using our technical support form, found here. If you do not provide details of your protocol or follow our recommendations, we will not be able to issue a replacement or refund.
