Refund & Returns Policy

Effective Date: July 27, 2026 Last Updated: September 8, 2026

This Refund & Returns Policy (the "Policy") governs all purchases of products (the "Products") from Kyreon Ltd Co ("Kyreon," "we," "us," or "our") through https://www.kyreon.co (the "Site"). This Policy is incorporated by reference into, and is part of, our Terms of Service. By placing an order you acknowledge that you have read, understood, and agree to this Policy.

1. Research-Use-Only Products — Read Before You Order

All Products sold by Kyreon are supplied strictly as research-use-only ("RUO") chemicals and reference materials intended for in-vitro laboratory research and development by qualified, trained professionals.

The Products:

  • are NOT drugs, foods, dietary supplements, cosmetics, or medical devices;
  • have NOT been evaluated or approved by the U.S. Food and Drug Administration (FDA) or any other regulatory authority for any use;
  • are NOT for human or animal consumption, ingestion, injection, inhalation, topical application, diagnostic, therapeutic, clinical, or any in-vivo use of any kind; and
  • are NOT intended to diagnose, treat, cure, mitigate, or prevent any disease or condition.

By placing an order you represent and warrant that you are a qualified researcher or a duly authorized representative of a research, academic, analytical, or commercial laboratory entity, that you are at least 21 years of age, that you are purchasing the Products solely for lawful in-vitro research, and that you will handle, store, use, and dispose of the Products in accordance with all applicable laws and good laboratory practices. Your qualified-researcher representation, your assumption of all risk associated with handling the Products, and your indemnification and limitation-of-liability obligations are set out in, and governed by, our Terms of Service and remain in full force regardless of any remedy under this Policy.

Because the Products are research reagents and not consumer goods, the suitability of a Product for any particular research purpose is your responsibility. Dissatisfaction with experimental results, a change of research direction, a mistaken interpretation of a Product's intended use, or any belief that a Product may be used for a purpose outside the RUO scope described above is not a basis for a refund, return, or exchange under this Policy.

2. All Sales Are Final (General Rule)

Except as expressly set out in Section 3, all sales are final. Because the Products are sensitive research reagents whose identity, purity, sterility, and stability cannot be verified or assured once they have left our custody and chain of control, we do not accept returns or exchanges and do not offer refunds for buyer's remorse, ordering errors, change of mind, no-longer-needed items, delayed research timelines, failure to meet a researcher's expectations, or any reason other than the limited exceptions stated below.

This no-return rule exists to protect the integrity of the research-reagent supply chain and is consistent with industry practice for laboratory chemicals and reference standards. It is not a denial of any non-waivable right you may have under applicable law.

3. Limited Exceptions — Damaged, Defective, Incorrect, or Non-Delivered Orders

We stand behind the condition of Products as shipped. You may be eligible for a replacement, store credit, or refund (at our election, see Section 6) only in the following circumstances, and only if you comply with the claim procedure and deadlines in Section 4:

3.1 Items Damaged in Transit. The Product arrived with damaged packaging, a broken seal, a cracked or leaking vial, compromised cold-chain (where cold-chain shipping was selected and paid for), or other physical damage that occurred before delivery.

3.2 Defective Items. The Product, as delivered, materially deviates from the specifications published on its product page or accompanying Certificate of Analysis ("COA") at the time of purchase. Claims of this type may require return of the affected Product and/or independent verification (see Section 5).

3.3 Wrong Item Shipped. You received a Product, quantity, concentration, or SKU different from what your order confirmation reflects.

3.4 Non-Delivery / Lost Shipment. A tracked shipment is confirmed lost in transit by the carrier, or is marked delivered but not received and our investigation confirms non-delivery. Consistent with the FTC Mail, Internet, or Telephone Order Merchandise Rule (16 CFR Part 435), if we are unable to ship your order within 1–3 days of receiving your properly completed order (or any longer period clearly stated at checkout), we will notify you and offer you the option to consent to a delay or to cancel for a prompt refund of amounts paid for the unshipped Product.

Exclusions from these exceptions. The exceptions above do not apply to: (a) Products that have been opened, used, reconstituted, repackaged, relabeled, or altered in any way except to the minimum extent necessary to discover the defect; (b) Products damaged by you after delivery, including by improper storage or handling; (c) Products refused at delivery, undeliverable, or returned to us due to an incomplete, inaccurate, or unverifiable shipping address you provided; (d) Products seized, detained, or destroyed by any customs, postal, or governmental authority; (e) minor variations in color, appearance, or labeling that do not affect the Product's stated specifications; or (f) claims submitted after the deadline in Section 4.

4. How to Make a Claim (Deadlines & Procedure)

To be eligible under Section 3, you must notify us within 14 days of the delivery date shown by the carrier's tracking (for damaged, defective, or wrong-item claims) or within 15 days of the expected delivery date (for non-delivery claims). Claims received after these windows will not be honored, except where a longer period is required by non-waivable law.

To submit a claim, email info@kyreon.co (or use ) with all of the following:

  1. your order number and the name on the order;
  2. a description of the problem and which exception in Section 3 applies;
  3. for damage or wrong-item claims: clear photographs of the outer packaging, shipping label, inner packaging, the affected Product, and any visible damage, taken before discarding any packaging;
  4. the lot/batch number on the Product label, where applicable; and
  5. whether you are requesting a replacement, store credit, or refund.

Do not return any Product unless and until we issue you a Return Merchandise Authorization ("RMA"). Unauthorized returns may be refused, are not eligible for a refund, and may be disposed of without credit. Retain the affected Product and all packaging until your claim is resolved.

5. Inspection, Verification & Restocking

5.1 Inspection. We may require that an affected Product be returned for inspection before approving any remedy. We may also, at our discretion, request independent third-party analytical verification of a defect claim, performed by a mutually acceptable accredited laboratory. If verification confirms the Product conformed to its published specifications and COA at the time of shipment, your claim may be denied and you may be responsible for the cost of the analysis.

5.2 Restocking Fee. Approved returns that fall outside the no-fault exceptions in Section 3 but that we nonetheless elect, in our sole discretion and as an accommodation, to accept may be subject to a restocking fee of 15% of the Product price, plus any non-refundable shipping and handling. No restocking fee applies to qualifying damaged-in-transit, defective, wrong-item, or non-delivery claims under Section 3.

6. Remedies, Refund Method & Timing

6.1 Our Remedy Election. For an approved claim under Section 3, we will, at our option, (a) ship a replacement of the same Product, (b) issue store credit, or (c) issue a refund. Where a remedy is required by non-waivable law, we will provide the remedy the law requires.

6.2 Refund Method. Any refund will be issued to the original payment method used for the purchase. If the original payment method is unavailable, expired, or closed, we may issue store credit or use another reasonable method. We do not refund to a different person, card, or account than the one used for the order.

6.3 What Is Refunded. An approved refund covers the price paid for the affected Product. Original shipping charges are refunded only where the entire order qualifies under Section 3 (damaged, defective, wrong item, or non-delivery). Expedited-shipping upcharges, cold-chain surcharges, customs duties, taxes, and other third-party fees are non-refundable except as required by law.

6.4 Refund Timing. Once a claim is approved (and any required return is received and inspected), we will issue the refund within 5–10 business days business days. Consistent with 16 CFR Part 435, where your right to a refund for unshipped or canceled merchandise has vested, we will issue that refund within seven (7) working days (or within one billing cycle where a credit account was used). Your bank or card issuer may take additional time to post the credit to your account.

6.5 Return Shipping — Who Pays. For qualifying damaged, defective, wrong-item, or non-delivery claims under Section 3, we pay return shipping and will provide a prepaid label or reimburse reasonable, documented return-shipping costs. For any return we accept as a discretionary accommodation outside Section 3, you pay return shipping, and we recommend a tracked, insured method; we are not responsible for returns lost or damaged in transit to us.

7. Order Cancellations & Address Errors

You may request cancellation of an order before it ships by emailing info@kyreon.co. We process orders quickly and cannot guarantee that a cancellation request will reach us before a Product has been packed or shipped. Once a Product has shipped, the order is governed by Sections 2–6. You are responsible for providing a complete and accurate shipping address; we are not responsible for orders delayed, lost, or undeliverable due to address errors you provided, and re-shipping costs in that situation are your responsibility.

8. Chargebacks & Payment Disputes

If you believe you are entitled to a refund, please contact us first at info@kyreon.co so we can resolve the matter directly. Filing a chargeback or payment dispute before contacting us and allowing a reasonable opportunity to cure is a breach of our Terms of Service.

By placing an order you acknowledge and agree that, in the event of a chargeback or payment dispute, we may present this Policy, your order records, our delivery and tracking records, your acceptance of the RUO terms and these refund terms at checkout, your qualified-researcher representation, and related communications to the card network, payment processor, or bank as evidence that the transaction was authorized and that the Products were delivered as described. Initiating a fraudulent or bad-faith chargeback — including a dispute that contradicts your acceptance of this Policy or seeks a refund for a reason this Policy excludes — may result in suspension of your account, recovery of the disputed amount plus dispute and processing fees, and referral to collections, to the extent permitted by law. Nothing in this Section limits your right to pursue a legitimate dispute you are entitled to bring under applicable law or card-network rules.

9. No Human-Use Implication; No Health Claims

Nothing in this Policy — including any reference to replacement, refund, satisfaction, quality, or condition — shall be construed as a representation, warranty, or implication that any Product is safe or appropriate for human or animal consumption or any in-vivo use, or that any Product has any health, therapeutic, or nutritional benefit. Any remedy under this Policy relates solely to the condition, identity, or delivery of a research reagent and not to any use prohibited by Section 1 or by our Terms of Service. Your assumption-of-risk, indemnification, qualified-researcher, and limitation-of-liability obligations in the Terms of Service remain in full force.

10. Limitation of Liability

To the maximum extent permitted by applicable law, and without limiting the limitation-of-liability and warranty-disclaimer provisions of our Terms of Service, our total liability arising out of or relating to any Product, order, or this Policy — whether in contract, warranty, tort, or otherwise — shall not exceed the amount you actually paid for the specific Product giving rise to the claim. We are not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including lost research, lost data, lost profits, or the cost of substitute reagents. Some jurisdictions do not allow certain limitations, so portions of this Section may not apply to you.

11. Governing Law & Dispute Resolution

This Policy is governed by the laws of the State of TX, without regard to its conflict-of-laws rules. Any dispute arising out of or relating to this Policy is subject to the binding arbitration, class-action waiver, and dispute-resolution provisions of our Terms of Service, which are incorporated here by reference. In the event of a conflict between this Policy and the Terms of Service regarding dispute resolution, the Terms of Service control.

12. Changes to This Policy

We may update this Policy from time to time. The version in effect at the time you place an order governs that order. We will post the current version on the Site with an updated "Last Updated" date. Material changes will be identified as such. Your continued use of the Site or placement of new orders after an update constitutes acceptance of the revised Policy.
