Reference No. 10-0118

Dear Ms. Lucia:

This is in response to your e-mail asking whether certain snowmobile shock absorbers are regulated under the Hazardous Materials Regulations (HMR; 49 CRF Parts 171-180). You provided a link to the product and state that the sleeve cover has air with a pressure of 50 to 150 psi, depending upon the application. You also state the extra air chamber on the side helps regulate the damper on the air shock and can potentially go to a maximum of 300 psi under compression, depending how it is adjusted.

Requirements applicable to the shipment of Accumulators intended to function as shock absorbers, struts, gas springs, pneumatic springs or other impact or energy-absorbing devices are prescribed in § 173.306(f) of the HMR. These devices are not subject to the HMR under the conditions specified in § 173.306(f)(4). As provided in § 173.306(f)(5), if the shock absorbers do not meet the applicable criteria, they may not be transported unless approved by the Associate Administrator of Hazardous Materials. The Office of Hazardous Materials Special Permits and Approvals may be contacted at (202) 366-4512.

I hope this information is helpful. Please contact this office should you have additional questions.
