Dear Ms. Bell,

This is in response to your May 27, 2014 letter requesting clarification on the proper classification of a fabricated product containing zinc, zirconium and tungsten under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).

According to your letter, zirconium is a Class 4 reactive material when in a powder form. However, the process of fabricating the product into a solid state renders the material safe for handling. You have provided laboratory test results that indicate the fabricated product does not meet the definition of a Class 4 material. Specifically, you are requesting confirmation that your product is not subject to the requirements of the HMR when in a solid, compact state.

In accordance with § 173.22, it is the shipper's responsibility to properly classify a hazardous material. This Office generally does not perform this function. However, based on the test data you provided, we agree that your fabricated product does not meet the definition of a Class 4 material. Therefore, if your company's product does not meet any other hazard class definition in Part 173, and is not a hazardous substance, hazardous waste, or marine pollutant, it is not subject to the HMR.

I trust this information is helpful. If you have further questions, please do not hesitate to contact this office.
