Frequently Asked Questions

What's the cost difference between ATA 300 and MIL-SPEC?

ATA 300 adds 30-50% to base IP67 cost. MIL-STD-810H adds 100-200% to base. ATA 300 testing is $3,000-5,000 in 4-6 weeks. MIL-SPEC testing is $10,000-25,000 in 8-12 weeks. Choose based on use case: ATA for commercial/rental, MIL-SPEC for military/aerospace.

Do I need both ATA 300 and MIL-SPEC?

Rarely. Most cases only need one standard. Choose ATA 300 for commercial air freight or rental fleets. Choose MIL-SPEC for military, aerospace, or extreme environment. If you ship via multiple modes (air + ground + sea), MIL-SPEC provides broader coverage. Budget is usually the deciding factor.
