- 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.
