Return eligibility
Eligibility depends on product condition, order status, and applicable policy. Contact support before sending any item back.
Order support
Straightforward order support.
A clear starting point for damaged, incorrect, or potentially eligible unopened orders.
Damaged shipment
Photograph the shipping carton, label, product packaging, and visible damage, then contact support promptly with the order number.
Incorrect item
Keep the item sealed and provide the product name, lot identifier, and order number so the shipment can be reviewed.
Unopened products
Unopened status does not automatically guarantee eligibility. Product integrity and research-material handling requirements must be reviewed first.
Requesting support
Use the contact form with your order number and a concise description. Do not return a package until instructions are provided.
Compliance note
Returned research products cannot be represented for human or veterinary use. All GREYLINE products remain research-use-only materials.
