General Products:

No need to purchase a shipping label! Atomic Defense will give you a pre-paid one.

Ballistic and Bulletproof Products:

Most companies will not accept any returns on ballistic or bulletproof items. We offer recertification as a courtesy.
Must be within 30 days of package delivery.
No need to purchase a shipping label! Atomic Defense will give you a pre-paid one.
A re-certification cost of 20% applies to returns of ballistic and bulletproof products.

The 20% recertification covers the cost of ensuring the armor is safe. Usually starting with X-Raying the armor for cracks underneath the coating, inspection for damage, and water damage testing. Without this 20%, we would not be able to offer returns on armor.
There is no way for us to know how or if it was used once shipped, and we have to consider them unsafe until retested, inspected and certified.
Exchanges and non-ballistic products do not have a re-certification cost.
