Refund policy
Last updated: July 14, 2026
Thank you for purchasing from KYDEN Supply.
Because of the sensitive nature of our laboratory research products and the need to preserve product integrity, all sales are final except in the limited circumstances described below.
Returns
We do not accept returns or exchanges for:
- Change-of-mind purchases
- Products ordered by mistake
- Unwanted products
- Products that have been opened, used, altered, reconstituted, damaged after delivery, or improperly stored
- Products returned without prior written authorization from KYDEN Supply
- Issues reported outside the applicable reporting period
Please review your order carefully before completing checkout.
Do not send any product back to KYDEN Supply unless our support team has provided written return authorization and return instructions.
Damaged Products
Please inspect your order immediately upon delivery.
If a product arrives visibly damaged, contact us at support@kydensupply.com within 48 hours of delivery.
Your message must include:
- Your full name
- Your order number
- A description of the issue
- Clear photographs of the outer shipping package
- A photograph of the shipping label
- Clear photographs of the product packaging and damaged product
Please retain all original packaging until your claim has been reviewed.
Claims submitted without sufficient documentation, after the 48-hour reporting period, or after the product has been opened, altered, used, or discarded may be denied.
Incorrect or Missing Items
If you receive an incorrect product or an item is missing from your order, contact support@kydensupply.com within 48 hours of delivery.
Please include your order number and clear photographs of:
- Everything received in the shipment
- The packing materials
- The shipping label
- The product labels
After reviewing the claim, KYDEN Supply may, at its discretion, provide a replacement, store credit, or refund for the affected item.
Lost or Undelivered Packages
If tracking shows that a package is still in transit but has not updated for more than three business days, contact support@kydensupply.com.
If tracking shows the package as delivered but you cannot locate it, please:
- Check around the delivery location.
- Ask household members, neighbors, property management, or front-desk personnel.
- Contact the shipping carrier.
- Contact KYDEN Supply promptly if the package remains missing.
KYDEN Supply may require completion of a carrier claim, written statement, or other supporting documentation before providing a resolution.
We are not responsible for packages delivered to an incorrect address entered by the customer during checkout, packages redirected by the customer, or packages lost or stolen after confirmed delivery. However, we will provide reasonable assistance with the carrier-claim process when possible.
If KYDEN Supply is unable to ship an order, we will provide an appropriate refund for the unshipped merchandise. Federal rules generally require online sellers to obtain consent to a shipping delay or refund the unshipped order when they cannot ship within the promised period.
Order Changes and Cancellations
To request a change or cancellation, contact support@kydensupply.com as soon as possible.
We will attempt to accommodate the request, but we cannot guarantee changes or cancellations after an order has been submitted.
Orders cannot be changed or canceled after they have entered fulfillment, received a shipping label, or shipped.
Approved Refunds and Replacements
After reviewing a claim, KYDEN Supply may approve one of the following remedies:
- Replacement of the affected item
- Store credit
- Partial refund
- Full refund for the affected item
The appropriate remedy will depend on the circumstances and applicable law.
Approval of one claim does not require KYDEN Supply to approve future claims involving different circumstances.
Refund Processing
Approved refunds will be issued to the original payment method whenever possible.
Please allow time for your bank, card issuer, or payment provider to process and post the refund. Processing times vary by financial institution.
Original shipping charges are non-refundable unless:
- KYDEN Supply shipped the wrong item;
- The order arrived damaged due to shipping;
- KYDEN Supply was unable to fulfill the order; or
- A refund is otherwise required by applicable law.
Return Shipping
Do not return products without written authorization.
If KYDEN Supply authorizes a physical return because we shipped an incorrect or damaged product, we will provide return instructions and determine whether a prepaid return label is appropriate.
Unauthorized returns may be refused, destroyed, or returned to the sender without refund.
Chargebacks and Payment Disputes
Please contact support@kydensupply.com before initiating a chargeback or payment dispute so we have an opportunity to investigate and resolve the issue.
Submitting a false or fraudulent payment dispute may result in suspension of the associated customer account and restriction of future purchases.
Nothing in this section limits any rights a customer may have under applicable law.
