Defiance International Terms of Service

Research-use-only materials

Defiance International offers high-purity chemical sequences strictly for laboratory research use (RUO). Materials are not intended for human or veterinary administration, diagnosis, treatment, prevention of disease, or any medical use.

By placing an order, you affirm that you are acquiring materials strictly for laboratory research, will handle every chemical sequence under appropriate controls, and will not administer any material to humans or animals.

No medical claims

Information made available through the storefront is not medical advice and does not make a medical, therapeutic, diagnostic, or safety claim about any material.

Final sale; no returns

All sales are final. The platform does not offer returns, refunds, credits, exchanges, replacements, or gift cards.

Safety recall custody

If a safety recall is initiated, the platform may coordinate internal custody and safety handling for affected materials. A recall does not create a monetary remedy, return right, refund, credit, exchange, or replacement right.

Shipping and tracking

Carrier tracking records hand-off evidence when available; it is not a delivery guarantee.
