Note: Product information may be found in the CFR Section 172.101

The following product information is to be used as a guide to determine the proper shipping container for your product.

  1. Hazardous materials description and proper shipping name(s):
    (Column 2 of the HazMat table in CFR section 172.101)
  2. Packaging Group for your product (I, II, III):
    (Column 5 of the HazMat table)
  3. Specific Gravity of product:
    (Relative Density equals Specific Gravity. Weight of one gallon of product divided by weight of one gallon of water [8.34] = Specific Gravity.)
  4. Vapor Pressure of your product in Kpa at 55 C:
    1. Vapor Pressure is required for liquids.
    2. A 250 Kpa minimum test pressure is required for all packaging Group I Products.
    3. Air Shipments of Packaging Group II, or III require a minimum Kpa rating of 100.
    4. Vapor pressure may be listed in many forms: atm, mmGH, Torr, or PSI. If you can provide us with any measurement and at what temperature we will convert it to Kpa at 55 C. Pressure: ATM mmHG Torr PSI Temperature: C F
  5. For Solids – What is the weight of your product in kilograms:
    Conversion Formula: Total weight of package in pounds / 2.2046 = kilograms



Example of UN marking for LIQUID hazardous materials:

UN = United Nations
1 = drum
A = steel
2 = open head (1 = tight head)
Y= class or packing group tested at

X = most hazardous (group I, II, III)
Y = medium hazard (group II, III)
Z = least hazard (group III)

1.5 = relative density (specific gravity)
150 = Kpa (kilopascal) or pressure tested at; indicates maximum specific gravity allowable for this packaging
96 = year of manufacture
USA = country of manufacture
SDCC = manufacturer’s UN registered mark
*Liquids certified drums may be used as a primary container for solids

Example of UN marking for SOLID hazardous materials:

UN/1A2/X = see above
150 = weight capacity tested in kg (kilograms)
S = tested for solids
*Solids certified drums may not be used as a primary container for liquids
