Dear Mr. Boros:
This is in response to your letter, and subsequent conversation with a member of my staff,
requesting clarification of the Hazardous Materials Regulations (HMR; 49 CPR Parts 171180)
applicable to a suture product and needle packaged in a hermetically-sealed foiled
pouch containing between 1.2 mL and 1.5 mL of an isopropanol-based wetting agent with
a flashpoint of 12°C. In your letter, you state that upon opening a sample of your client's
foil pouch, free liquid was visibly present. You ask whether the proper shipping name
"Solids containing flammable liquids, n.o.s." is appropriate, and, is therefore subject to the
HMR.
Based on the scenario described in your letter, the answer is no, you may not use the
proper shipping name "Solids containing flammable liquids, n.o.s." Further, it is the
opinion of this Office that your client's product is fully subject to the requirements of the
HMR and another description must be selected appropriate to the packaged substance. The
proper shipping name "Solids containing flammable liquids, n.o.s.," in the § 172.101
Hazardous Materials Table refers the reader to § 172.102(c)(I) Special provision 47.
Special provision 47 excepts from the HMR sealed packets that contain less than 10 mL of
a flammable liquid in Packing Group II or III when the liquid is completely absorbed onto
a solid material. Although your client's product contains less than 10 mL of a flammable
liquid, the liquid is not completely absorbed onto a solid material and free liquid is visible.
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

I have been speaking with Adam in the Hazmat Information Center in an effort to obtain confirmation that the
product described below is subject to the HMR. Although he did provide verbal confirmation, I am in need of a
written response.
The suture product in question consists of an 18" length of catgut attached to a small curved needle. The suture and
needle are placed in a hermetically sealed foil pouch with between 1.2ml and 1.5ml of an Isopropanol based wetting
agent. The sealed foil packet is further sealed in another plastic/paper pouch.
Each selling unit consists of twel ve packets in a heavy paper sleeve. Printed on the bottom panel of the selling unit it
states "When product is packaged in fluid each package contains:" then lists the components that comprise the
wetting agent. [See sleeve.pdf]
The MSDS provided by our supplier indicates the wetting agent solution possesses a flash point of 12°C and is
identified as UN1219, Isopropanol solutions, a class 3 packing group II flammable liquid. [Wetting Agent SDS.pdf]
In a conversation with the supplier of the suture product, they stated the wetting agent is a free liquid. Upon opening
and inverting the foil packet, liquid was present.
Am I accurate in my understanding based on the information provided that when packaged with the alcohol-based
wetting agent, the suture product is subject to the requirements of the HMR?

Robb Boros
