As a motor-carrier owner, here is what you need to know based on 49 CFR 173.306 for limited quantities of compressed gases:
* General Exemptions: Limited quantity shipments of compressed gases are excepted from labeling (unless transported by air) and from standard specification packaging requirements, provided they are packaged according to the rules. They are also exempt from Part 172 Subpart F (Placarding), most of Part 174 (except § 174.24), and most of Part 177 (except § 177.817).
* Weight Limit: Except as otherwise provided, each package must not exceed a gross weight of 30 kg (66 lbs.).
* Specific Packaging Conditions: The regulation provides exceptions and standards for specific container types, including:
* Small containers of not more than 4 fluid ounces capacity (excluding cigarette lighters).
* Refillable metal containers filled with non-hazardous materials and charged with a nonflammable, nonliquefied gas, subject to specific pressure and capacity limits (such as containers under 1 quart at 170 psig or under 30 gallons at 75 psig).
* Metal aerosol containers (capacities up to 1 L) that meet specific design, pressure limits (varying by container type like non-DOT, DOT 2P, 2Q, or 2Q1), liquid fill limits, outer packaging (strong outer packagings), and rigorous pressure-testing requirements (such as hot water bath tests, alternative water bath tests, automated pressure tests, or weight tests).
