Due to the research-grade, single-use nature of our products, CoreLabs does not offer a guaranteed return or refund window. Once an order has shipped, returns and refunds are considered on a case-by-case basis only, at our sole discretion.
Non-returnable items
Opened, reconstituted, or used products are not eligible for return under any circumstances, regardless of when they were purchased.
The following items are also non-returnable:
- Products that have been reconstituted or partially used
- Products not in original, sealed packaging
- Products improperly stored after delivery (must be kept at −20°C)
- Sale or clearance items
Damaged or incorrect orders
If your order arrives visibly damaged in transit, or you receive an incorrect product, please contact our support team within 48 hours of delivery with your order number and photos of the issue. We will review each claim individually and may offer a replacement or refund at our discretion.

Every situation is different, so if you’d like to ask about a potential return, reach out to our support team at support@trycorelabs.com with your order number and the reason for your request. Our team will review your request and let you know if a return is possible.
