Class I-IV Commodities are broken down as follows:

Class I:

Class I commodities are essentially noncombustible products on wooden or nonexpanded polyethylene solid deck pallets, in ordinary corrugated cartons with or without single-thickness dividers, or in ordinary paper wrappings with or without pallets.

Examples:

  • Appliances noncombustible, electrical
  • Cement in bags
  • Ceramics
  • Dairy products in nonwax-coated containers (excluding bottles)
  • Dry insecticides
  • Foods in noncombustible containers
  • Fresh fruits and vegetables in nonplastic trays or containers
  • Frozen foods
  • Glass
  • Glycol in metal cans
  • Gypsum board
  • Inert materials, bagged
  • Insulation, noncombustible
  • Noncombustible liquids in plastic containers having less than a 5-gallon (19 L) capacity
  • Noncombustible metal products

Class II

Class II commodities are Class I products in slatted wooden crates, solid wooden boxes, multiple-thickness paperboard cartons or equivalent combustible packaging material with or without pallets.

Examples:

  • Alcoholic beverages not exceeding 20-percent alcohol, in combustible containers
  • Foods in combustible containers
  • Incandescent or fluorescent light bulbs in cartons
  • Thinly coated fine wire on reels or in cartons

Class III

Class III commodities are commodities of wood, paper, natural fiber cloth, or Group C plastics or products thereof, with or without pallets. Products are allowed to contain limited amounts of Group A or B plastics, such as metal bicycles with plastic handles, pedals, seats and tires.

Examples:

  • Aerosol, Level 1 (see Chapter 28)
  • Combustible fiberboard
  • Cork, baled
  • Feed, bagged
  • Fertilizers, bagged
  • Food in plastic containers
  • Furniture: wood, natural fiber, upholstered, nonplastic, wood or metal with plastic-padded and covered armrests
  • Glycol in combustible containers not exceeding 25 percent
  • Lubricating or hydraulic fluid in metal cans
  • Lumber
  • Mattresses, excluding foam rubber and foam plastics
  • Noncombustible liquids in plastic containers having a capacity of more than 5 gallons (19 L)
  • Paints, oil base, in metal cans
  • Paper, waste, baled
  • Paper and pulp, horizontal storage, or vertical storage that is banded or protected with approved wrap
  • Paper in cardboard boxes
  • Pillows, excluding foam rubber and foam plastics
  • Plastic-coated paper food containers
  • Plywood
  • Rags, baled
  • Rugs, without foam backing
  • Sugar, bagged
  • Wood, baled
  • Wood doors, frames and cabinets
  • Yarns of natural fiber and viscose

Class IV

Class IV commodities are Class I, II or III products containing Group A plastics in ordinary corrugated cartons and Class I, II and III products with Group A plastic packaging, with or without pallets. Group B plastics and free-flowing Group A plastics are also included in this class.

Examples:

  • Aerosol, Level 2 (see Chapter 51)
  • Alcoholic beverages, exceeding 20-percent but less than
  • 80-percent alcohol, in cans or bottles in cartons
  • Clothing, synthetic or nonviscose
  • Combustible metal products (solid)
  • Furniture, plastic upholstered
  • Furniture, wood or metal with plastic covering and padding
  • Glycol in combustible containers (greater than 25 percent and less than 50 percent)
  • Linoleum products
  • Paints, oil base in combustible containers
  • Pharmaceutical, alcoholic elixirs, tonics, etc.
  • Rugs, foam back
  • Shingles, asphalt
  • Thread or yarn, synthetic or nonviscose

Class High Hazard Commodities are broken down as follows:

High-hazard commodities

High-hazard commodities are high-hazard products presenting special fire hazards beyond those of Class I, II, III or IV. Group A plastics not otherwise classified are included in this class.

Examples:

  • Aerosol, Level 3 (see Chapter 51)
  • Alcoholic beverages, exceeding 80-percent alcohol, in bottles or cartons
  • Commodities of any class in plastic containers in carousel storage
  • Flammable solids (except solid combustible metals)
  • Glycol in combustible containers (50 percent or greater)
  • Lacquers, which dry by solvent evaporation, in metal cans or cartons
  • Lubricating or hydraulic fluid in plastic containers
  • Mattresses, foam rubber or foam plastics
  • Pallets and flats which are idle combustible
  • Paper and pulp, rolled, in vertical storage which is unbanded or not protected with an approved wrap
  • Paper, asphalt, rolled, horizontal storage
  • Paper, asphalt, rolled, vertical storage
  • Pillows, foam rubber and foam plastics
  • Pyroxylin
  • Rubber tires
  • Vegetable oil and butter in plastic containers

Group A plastics

Group A plastics are plastic materials having a heat of combustion that is much higher than that of ordinary combustibles, and a burning rate higher than that of Group B plastics.

Examples:

  • ABS (acrylonitrile-butadiene-styrene copolymer)
  • Acetal (polyformaldehyde)
  • Acrylic (polymethyl methacrylate)
  • Butyl rubber
  • EPDM (ethylene propylene rubber)
  • FRP (fiberglass-reinforced polyester)
  • Natural rubber (expanded)
  • Nitrile rubber (acrylonitrile butadiene rubber)
  • PET or PETE (polyethylene terephthalate)
  • Polybutadiene
  • Polycarbonate
  • Polyester elastomer
  • Polyethylene
  • Polypropylene
  • Polystyrene (expanded and unexpanded)
  • Polyurethane (expanded and unexpanded)
  • PVC (polyvinyl chloride greater than 15-percent plasticized, e.g., coated fabric unsupported film)
  • SAN (styrene acrylonitrile)
  • SBR (styrene butadiene rubber)

Group B plastics

Group B plastics are plastic materials having a heat of combustion and a burning rate higher than that of ordinary combustibles, but not as high as those of Group A plastics.

Examples:

  • Cellulosics (cellulose acetate, cellulose acetate butyrate, ethyl cellulose)
  • Chloroprene rubber
  • Fluoroplastics (ECTFE, ethylene-chlorotrifluoroethylene copolymer; ETFE, ethylene-tetrafluoroethylene copolymer; FEP, fluorinated ethylene-propylene copolymer)
  • Natural rubber (nonexpanded)
  • Nylon (Nylon 6, Nylon 6/6)
  • PVC (polyvinyl chloride greater than 5-percent, but not exceeding 15-percent plasticized)
  • Silicone rubber

Group C plastics

Group C plastics are plastic materials having a heat of combustion and a burning rate similar to those of ordinary combustibles.

Examples:

  • Fluoroplastics (PCTFE, polychlorotrifluoroethylene;
  • PTFE, polytetrafluoroethylene)
  • Melamine (melamine formaldehyde)
  • Phenol
  • PVC (polyvinyl chloride, rigid or plasticized less than 5 percent, e.g., pipe, pipe fittings)
  • PVDC (polyvinylidene chloride)
  • PVDF (polyvinylidene fluoride)
  • PVF (polyvinyl fluoride)
