Import Tips
• Secure Bureau of Industry and Security (BIS) export licenses alongside ATF approvals for defense-related explosives
• Label packages with UN 0114 markings and maintain temperature control below 50°C to prevent decomposition
• Avoid common error of shipping without DOT-approved packaging, resulting in carrier refusals and fines
