Hazmat Packaging: DOT Compliance for Reused IBCs

Critical DOT Requirements

• Verify UN marking visibility and match to product compatibility (packing group, material).
• Retest/inspect per 49 CFR 180.352 (leakproofness every 30 months; periodic every 60 months).
• Maintain test records for at least the container service life as required by DOT.
• Apply correct hazard labels, markings, and shipping papers for each load.
• Remove or cover obsolete placards and labels to prevent misidentification.

Common Violations to Avoid

• Illegible or missing UN markings on bottle or cage.
• Out-of-date leakproofness or periodic tests.
• Mixed hazard labels from previous contents left in place.
• Improper closure torque or missing tamper seals.
• Using non-UN IBCs for regulated hazmat product.

Testing & Recordkeeping

Keep leakproofness and periodic test records with test dates, pressures, technician, and results. Retain for the container's service life. Ensure test marks are legible.
