Do not return a parcel without written instructions. Contact support with the order number, affected item, batch number, and a description of the issue. Include photographs of the parcel, label, and contents when damage or an incorrect item is involved.
Product integrity
Research materials may be ineligible for return after dispatch because storage history and chain of custody cannot be independently verified. Approved remedies depend on the facts, applicable law, and the Refund Policy. Keep all packaging until support confirms the next step.
