Refund and Returns Policy
Refund and returns policy for HK Peptides Worldwide research chemicals: the 30-day claim window, eligibility, non-returnable material and how to claim.
Refund and Returns Policy
Research chemicals are sensitive materials, so our returns policy is built around what can genuinely be verified. This policy applies to orders of research materials supplied by HK Peptides Worldwide LLC.

1. Claim Window
Claims must be raised within 30 days of delivery. After 30 days we are unable to offer a refund, replacement or exchange. Inspect your shipment as soon as it arrives — see section 4 for transit damage, which should be reported promptly.
2. What We Can Replace or Refund
| Situation | Outcome |
|---|---|
| Material does not match the specification or COA for the batch | Replacement or refund |
| Incorrect item supplied | Replacement or refund |
| Item arrives damaged, short, or with evidence of a temperature excursion in transit | Replacement or refund, assessed with the carrier and our lot records |
| Item is defective on arrival and unused | Replacement or refund, subject to inspection |
3. What We Cannot Accept
Because integrity cannot be verified after the fact, the following cannot be returned or refunded:
- opened, punctured, reconstituted or partially used vials or kits;
- material stored, handled or shipped contrary to the storage conditions on its COA;
- material past its stated shelf life;
- material that has been altered, relabelled or repackaged after delivery;
- items ordered in error or no longer required (returns for these are only accepted with our prior written agreement, at the buyer’s cost);
- orders affected by import restrictions, customs refusal or a missing permit in the destination country — buyers are responsible for import compliance (see Compliance & Buyer Eligibility).
4. Damaged, Short or Delayed Shipments
Contact us promptly — and no later than 30 days after delivery — with:
- your order reference or invoice number;
- the product name and the lot number from the vial label;
- photographs of the outer packaging, the inner packaging and the affected items;
- a short description of the problem.
Keep the packaging and the goods as received while the claim is assessed; it may be needed for a carrier claim. Where the problem is confirmed, we will arrange a replacement or issue a refund.
5. How to Start a Return
Returns require prior written authorisation — please do not send anything back without it, as unauthorised returns cannot be accepted or credited. Email [email protected] with the details in section 4, and we will confirm whether to return the goods and provide shipping instructions.
Where a return is authorised and the issue is not our error, return shipping is at the buyer’s cost; where the issue is our error (incorrect, defective or damaged item), we cover the return. Where goods cross a border, the buyer is responsible for customs documentation and any duties.
6. Refunds
Once an authorised return is received and inspected, we will notify you of the approval or rejection of your refund. Approved refunds are issued to the original payment method or, where the original method cannot be used, by an agreed alternative, within a reasonable period after approval. Refund processing times depend on the payment method and your provider.
7. Exchanges
We replace items where they are defective, damaged or incorrectly supplied. If you need the same item in a different configuration, contact us and we will confirm availability and any price difference.
8. Late or Missing Refunds
If you have been notified of an approved refund but have not received it, check your account again and allow the normal processing time for your payment method, then contact us at [email protected] and we will confirm the transfer details and reference.
