11 Steps for LQ 49 CFR Shipping by Ground Best Practices

  1. Determine if the substance is CLASSIFIED as a hazardous material in transportation.  Most shippers will use section 14 on the material’s Safety Data Sheet (SDS). If the material is a hazardous material, the proper shipping name and UN number most likely will be found there.  It may also be provided in the company’s shipping system.
    1. If the information is not listed on an SDS or in the shipping system, the hazard class/division must be determined by comparing the physical characteristics of the materials with the classification criteria found in 49 CFR 173 Subpart D.
    2. If the information on the physical characteristics of the material is not available, testing must be performed to determine the hazard class(es).
    3. This section may also provide information about whether the material is a HAZARDOUS SUBSTANCE.  Check 49 CFR 172.101 Appendix A to see if the material or its components are listed.  If the material is being shipped at a quantity equal or above the listed RQ, the material is a hazardous substance and must be identified as such on the package and shipping document. 
  2. Check the Hazardous Materials Table (49 CFR 172.101, Columns 2 and 4) for the UN NUMBER and PROPER SHIPPING NAME. If there is a “G” in column 1, the technical name must be shown in parenthesis with the proper shipping name. (49 CFR 172.101(b)(4))
    1. Some print versions of the 49 CFR provide a Numerical “Cross-Reference” table to use if only the UN number for the material is provided. Locations for this table vary so be sure to check with the publisher of your book for its location. 
  3. Note the PRIMARY AND SUBSIDIARY HAZARD CLASSES/DIVISIONS (Column 6) and PACKING GROUP (Column 5) of the material.  If more than one packing group is listed, check the SDS to determine which packing group to apply. 
  4. Determine if the material is permitted to be transported as a LIMITED QUANTITY. Look at Column 8A.  If the word “NONE” appears in the column, the material must not be shipped as a limited quantity.  
  5. Read all SPECIAL PROVISIONS listed in Column 7.  Special provisions are found in 49 CFR 172.102.
  6. If the material is not forbidden for transport as a limited quantity, go to the PACKING AUTHORIZATION listed in Column 8A.  To find the authorization, the 3-digit number is preceded by “173.”.  If “150” is listed in Column 8A, the packaging authorization can be found in “173.150”.
  7. Ensure the packaging complies with the general requirements for packaging in 173.24 and 173.24a and the specific provisions found in the packaging authorization.
  8. Prepare the PACKAGING.  Make sure the package weighs 30 kg G or less. 
  9. MARK the package as required by 49 CFR 172 Subpart D.  
  10. If preparing an OVERPACK, make sure to:
    1. Duplicate all markings on the outside of the overpack, 
    2. Mark the outside of the overpack with the OVERPACK marking, and 
    3. Add the overpack identification mark if required.
  11. SHIPPING PAPERS are not required unless the material is a hazardous waste or a reportable quantity of a hazardous substance.
