Mr. Tom Dunaway

Reference No. 16-0182
Dear Mr. Dunaway:
This letter is in response to your November 3, 2016, email requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the use of pre-
printed shipping papers and recent changes to the Hazardous Materials Table (HMT).
Specifically, you reference a final rule published by the Pipeline and Hazardous Materials Safety
Administration (PHMSA) on June 2, 2016, titled Hazardous Materials: Miscellaneous
Amendments (RRR) [HM-218H; 81 FR 35483]. In this final rule, PHMSA revised certain HMT
entries, including the removal of the packing group (PG) II designation for certain explosives.
As discussed in the preamble of this rulemaking, this amendment was intended to alleviate
confusion and frustration of shipments, as well as align with international regulations.
You indicate in your email that you currently ship explosives using pre-printed shipping papers
that list the PG II designation in the basic description although it was removed in the HM-218H
Final Rule. Specifically, you ask if you may continue to use these pre-printed shipping papers.
The answer is yes. In accordance with § 172.101(I)(1)(ii), when a change is made to the HMT, a
shipper may continue to use pre-printed shipping papers until the supply is depleted or for a one-
year period, subsequent to the effective date of a regulatory change to the HMT. As the effective
date of the HM-218H Final Rule was July 5, 2016, the pre-printed shipping papers may be used
until they are depleted or through July 5, 2017, whichever comes first. However, after
July 5, 2017, a shipping paper may no longer display the PG II designation for those HMT
entries changed in HM-218H.

all pallance
I am requesting an interpretation on the following question
The final rule issued in HM Docket 218 H dated June 2, 2016 eliminated all
references to class 1 materials in the table 172.101. Also section 172.202(a)(4)
exempts class 1 materials from the requirement of entering the PG group on
shipping papers.
Sections 173.62(a) requires all packages for class 1 to be tested at the PG II level.
Most companies that ship explosives have for years had pre-printed shipping papers
that have the PG column filled in. We understand that in accordance with the
provisions of 172.202(a)(4) that the PG I is not required on shipping papers but the
question that arises is if a shipper places PG II on the shipping paper is it now a
violation, even though 173.62(a) does require those packages to be tested at the PG
Il level.
Thank you for your replay
