Shipping & Returns
Last updated August 3, 2026
Where we ship
We ship within the United States only, including Alaska and Hawaii. We do not ship internationally and we do not release orders to freight forwarders arranging onward shipment outside the United States.
Some materials may be restricted in particular states or localities. If we cannot lawfully ship an item to your address, we will tell you and refund that item in full.
Processing and dispatch
| Order placed | Dispatched |
|---|---|
| Business day, before the daily cutoff | Same business day |
| Business day, after the daily cutoff | Next business day |
| Weekend or federal holiday | Next business day |
The daily cutoff is shown at checkout. Orders flagged for payment or address verification are dispatched once verification clears.
Transit and tracking
You receive a tracking number by email as soon as the label is generated. Typical transit is two to five business days depending on destination and service selected. Transit times are carrier estimates, not guarantees. Weather, carrier backlogs, and holiday volume can extend them, and those delays are outside our control.
Cold chain
Temperature-sensitive materials ship with appropriate insulation and coolant where required. Because we cannot verify how a package is stored after delivery, store temperature-sensitive materials according to the handling information supplied with them as soon as the package arrives.
Wrong address
Enter your address carefully. If a package is returned to us as undeliverable because of an address error, we will re-ship it once you confirm a corrected address, and a second shipping charge applies. If you ask us to cancel instead, we refund the goods but not the original shipping.
Damaged, incorrect, or missing items
Contact us within 7 days of delivery at support@coastlineresearchsupply.com with your order number and photographs of the packaging and contents. If we sent the wrong item, or it arrived damaged, we replace it at our cost or refund it in full, your choice. We do not ask you to ship a damaged item back before we make it right.
If tracking shows delivered and the package is not there, tell us within 7 days. We will open a carrier trace and work it with you.
Returns
What we accept
Unopened consumables and labware in original, undamaged packaging may be returned within 30 days of delivery for a refund of the purchase price. Request a return authorization before shipping anything back; returns received without one cannot be matched to an order.
What we cannot accept
- Any item that has been opened, used, or had its seal broken.
- Temperature-sensitive research materials, once dispatched. Sterility and cold chain cannot be verified after a package leaves our control, and we will not return such an item to inventory.
- Sterile items whose packaging integrity has been compromised.
- Items returned more than 30 days after delivery.
These exclusions exist because we cannot resell material whose handling we cannot vouch for. They do not apply to items that arrived damaged, incorrect, or defective, which are covered above.
How refunds work
Return shipping is the customer's responsibility except where we sent the wrong item or it arrived damaged. Approved refunds are issued to the original payment method within five business days of our receiving and inspecting the return. Original shipping charges are not refunded on a change-of-mind return. Your bank may take additional time to post the credit.
Cancellations
We can cancel an order any time before it is dispatched. Once a label is generated we cannot recall the package, and the return policy above applies instead.
