Changes to Packages Shipped by Air

PHMSA issued a final rule regarding the packaging, closure, liners and absorbents when shipping by air. The changes in this rulemaking will align with the International Civil Aviation Organization (ICAO) Technical Instructions.  A summary of the changes is:

  • Class/Division 4.1, 4.2, 4.3, 5.1 or 8 Packing Group III materials must be in packaging, which is a Packing Group II performance level.
  • The packaging must be constructed to resist the effects of temperature and vibration changes which normally occur during air transportation.
  • Liquid Packing Group I materials will require:
    • Secondary means of closure and
    • Absorbent materials of liquid in Classes/Divisions 3, 4, 5.1, 6.1, or 8 in glass, earthenware, plastic or metal inner packagings
      • Sufficient absorbent material to absorb the entire contents of the inner packaging
      • Absorbent must not react with the liquid
      • Liquid Packing Group II and III materials will require:
        • Secondary means of closure
          • If cannot be applied or impractical, then inner packaging can be placed in a leakproof liner or bag

Secondary means of closure could be tape, child resistant closures, friction seleeves, locking rings, heat seals, etc.

These requirements are for air shipments.
