Based on 49 CFR 173.150, exceptions for Class 3 flammable and combustible liquids apply only if this section is specifically referenced in the § 172.101 Table for that material. Depending on how your shipment qualifies, here are the practical rules and requirements:
* Limited Quantities: If you package flammable and combustible liquids in combination packagings, they are exempt from labeling and placarding requirements (unless transported by aircraft), specification packaging requirements, and shipping paper requirements (unless the material is a hazardous substance, hazardous waste, marine pollutant, or transported by aircraft or vessel). Each package must meet general packaging rules and cannot exceed a gross weight of 30 kg (66 pounds). The maximum net capacity for inner packagings depends on the packing group:
* *Packing Group I flammable liquids:* Inner packagings cannot exceed 0.5 L (0.1 gallon) each.
* *Packing Group II flammable liquids:* Inner packagings cannot exceed 1.0 L (0.3 gallons) each.
* *Packing Group III flammable liquids and combustible liquids:* Inner packagings cannot exceed 5.0 L (1.3 gallons) each.
* Alcoholic Beverages: Transported via motor vehicle, vessel, or rail, alcoholic beverages (wine and distilled spirits containing 24% or less alcohol by volume, or in inner packagings of 5 L / 1.3 gallons or less, or Packing Group III beverages in packagings of 250 liters / 66 gallons or less) are completely free from the requirements of this subchapter.
* Aqueous Solutions of Alcohol: Aqueous solutions with 24% or less alcohol by volume and no other hazardous material can be reclassed as a combustible liquid, and are entirely exempt from the requirements of this subchapter if they contain at least 50% water.
* Combustible Liquids in Non-Bulk Packagings: Materials classed as combustible liquids in non-bulk packagings are not subject to subchapter requirements unless they are a hazardous substance, hazardous waste, or marine pollutant.
* Combustible Liquids in Bulk Packagings or Hazardous Materials: If a combustible liquid is in a bulk packaging, or is a hazardous substance, waste, or marine pollutant, it is exempt from most subchapter rules *except* those covering shipping papers/manifests, package markings, bulk package identification numbers, bulk placarding, aircraft/vessel carriage, incident reporting, basic packaging/general rules, worker training, emergency response information, and specific motor carrier safety regulations. Additionally, certain high-flashpoint mixtures (at or above 93 °C / 200 °F comprising at least 99% of the volume) are not subject to the requirements if not transported at or above their flash point.
* Retail Products Containing Ethyl Alcohol: Beverages, food, cosmetics, medicines, and similar retail products containing up to 70% ethyl alcohol are excepted from the Hazardous Materials Regulations (HMR), provided they meet specific inner packaging size limits (with glass and non-glass limits varying from 0.23 L to 3.8 L for liquids, or 0.22 kg to 3.62 kg for solids), are properly marked with the company name and "Contains Ethyl Alcohol" when exceeding certain sizes, stay under a 5.6 L (1.5 gallon) net liquid or 15 kg (33 pound) net solid limit per outer package (with a 30 kg / 66 lb gross weight limit), and have inner packagings securely cushioned to prevent breakage and shifting.
