Cargo Tank Inspection & Testing

Safety is the top priority when rolling across the nation carrying a load in your cargo tank. With a combined experience spanning over 60 years, Tank Specialties of California works closely with the California Air Resources Board (CARB) to follow their regulations to the letter. Our team is CARB and Department of Transportation (DOT) trained and certified to run tank inspections. We stay on top of the current regulations to keep our loyal customers—safe on the road. We’re trained to ensure your cargo tanks are structurally sound and void of leakage.
Get and retain your coveted pressure vessel tank inspection numbers to display on your tanks. If inspection findings identify damage or pressure-related issues, certified repairs may be required to bring your tank back into compliance.
