Concrete Pipes

ASTM C76 covers reinforced concrete culvert, storm drain, and sewer pipe, while ASTM C14 applies to non-reinforced concrete sewer, storm drain, and culvert pipe. Public-works contracts typically mandate compliance with one of these standards, and importers must obtain mill certifications and test reports from the foreign manufacturer to demonstrate conformance.

Many state and municipal contracts require pre-qualified products or domestic-preference provisions under Buy America or Buy American requirements, particularly for federally funded projects. Importers and contractors should review project specifications and federal funding conditions carefully before committing to imported pipe, as substitution may require engineering approval or a waiver.
