Dear Mr. Foryt:
This letter is in response to your May 1, 2025 email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to markings on UN specification non-bulk performance-oriented packagings. Specifically, can a single UN symbol be used to meet the requirements in § 178.503(a)(1) when multiple (e.g., two or more) markings are included on a packaging.
No. In accordance with § 178.3(c), the HMR specifically states if more than one marking appears on a packaging, each marking must appear in its entirety. Thus, each marking string must include its own UN symbol or the letters "UN" as part of the marking string.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Dirk Der Kinderen
Chief, Standards and Development Branch
Standards and Rulemaking Division
