Ref. No. 12-0128

Dear Mr. Thompson:

This responds to your June 4, 2012 letter requesting clarification of the small quantity exceptions under § 173.4 of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Your understanding is that petroleum crude oil (UN1267) may be shipped under the conditions outlined in § 173.4. Additionally, in your letter, you describe plans to package an article (i.e., a pyncnometer) consisting of a metal cylinder that has a capacity of 10 mL and will be used to transport the crude oil for research analysis. You request clarification of the meaning of "prototype testing" as used in § 173.4(a)(6). Specifically, you ask whether the packaging must be independently tested using your inner receptacles or whether you can use a commercially produced outer packaging already tested for loads greater than 64 pounds.

Your understanding of the eligibility of crude oil for the small quantity exceptions is correct. Class 3 (flammable liquid) material such as petroleum crude oil (UN1267) may be transported under the conditions of § 173.4. The phrase "prototype testing" is not defined in the HMR. Its common meaning refers to an original model on which something is patterned; or a first full-scale and usually functional form of a new type or design of a construction. Finally, the completed package (as prepared for transportation) must be capable of sustaining the testing in § 173.4(a)(6). A successfully tested commercially available packaging similar to your intended completed package that differs only in minor respects may be used without undergoing further testing provided this difference would not affect its performance under requirements specified in § 173.4(a)(6). For example, you could switch out the inner metal receptacles of a successfully tested packaging with your pyncnometers.

I hope this information is helpful. If you have further questions, please contact this office.

Sincerely,
