Refund & Return Policy
Last updated June 21, 2026
This policy applies to all purchases of reference materials from Helix Reagents LLC.
Temperature-sensitive materials
Where temperature-controlled packaging is required, the applicable handling, receipt, and return terms are confirmed before the order is finalized. Any return or refund is governed by the current terms and the facts of the issue.
Damaged, incorrect, or non-conforming items
If a product arrives damaged, is the wrong item, or does not match the analytical values on its Certificate of Analysis, use the research inquiry form within 7 days of delivery with your order reference and photographs. We will provide a replacement or a refund of the affected item.
Non-delivery
If an order is not delivered within a reasonable period and tracking confirms it was not received, contact us and we will investigate with the carrier and reship or refund as appropriate.
Order cancellation
Orders may be cancelled for a full refund any time before they are dispatched. Once an order has shipped it is subject to the return conditions above.
How refunds are issued
Approved refunds are returned to the original payment method, typically within 5–10 business days of approval. We may refuse refunds on orders that indicate intended human or veterinary use or potential illegality.
