Braulio-Martinez Sartorius Stedim Biotech Supply Chain Manager Sartorius Stedim Filters, Inc. Road 128 Int 376, P.O. Box 6 Yauco, Puerto Rico 00698 Reference No. 09-0300 Dear Mr. Braulio-Martinez: This is in response to your letter, telephone conversations with a member ofmy staff, and emails concerning "UN 3270, Nitrocellulose membrane filters, with not more than 12.6% nitrogen, by dry mass, 4.1 (flammable solid), Packing Group (PG) II," your company manufactures and distributes. You ask ifthese filters are excepted from regulation as a Division 4.1 material under the requirements prescribed in Special Provision (SP) 43 of § 172.102 ofthe Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). On July 22, 2010, you provided this Office with United Nation's (UN) Gap, Scientific Weight, and Burn Rate test results (Laboratory Report No.1 0045-1 0047) for these filters that were prepared on April 22, 2010, 1:>Y Stresau Laboratory, Inc., for Speciality Disposal Services, Inc., of Mountain Lakes, NJ. You state the filters are manufactured in the shape ofa circular disc and range in diameter from 13 millimeters (0.51 inches) to 90 millimeters (3.54 inches). You state the largest filter contains 0.42 grams (0.02 ounces) ofnitrocellulose. You also state the package consists ofan inner packaging that contains 100 filters in one sealed packet with wax paper separators between each filter, the packets are then placed in a plastic tray base, a tray cap is closed onto the top ofthe base and held in place with two pieces oftape on opposite sides, and several closed tray packagings (e.g., 1,000 discs) are placed in one non-specification fiberboard box. Under § 173.22, it is a shipper's responsibility to properly classify and describe a hazardous material. This office does not normally perform that function. However, based on the information you provided, it is the opinion ofthis office that the nitrocellulose membrane filters you describe do not qualifY for the two exceptions prescribed in SP 43. First, the laboratory test results do not support their entire exclusion from the HMR. The filters meet the definition ofa Division 4.1, PO II material, as defined by UN and U.S. Department of Transportation criteria for testing flammable solids (see Modified UN Division 4.1 Burn Rate Test N.1 and 49 CFR 173.124(a)), because "the sample ignited and traveled a distance of 1 00 mm in 7.95 second, and a wetting agent did not inhibit the propagation ofcombustion." Second, as stated in your company's material safety data sheet, improperly stored nitrocellulose membrane filters may decompose and produce nitrous vapors or self-ignite, and when exposed to fire may also produce <<>> explosive flames. Based upon this information, it appears that your product has the potential of being a self-ignition source. Ifthis is the case, your product is forbidden from transportation commerce based on the requirements of § 173.21(t). Third, although you did not provide the mass ofall the filters your company manufactures, you did state the largest filter weighs 0.42 grams. Therefore, please note that your company's packaging of 100 filters in one sealed packet will exceed the 0.5 gram limit that SP 43 requires to be enclosed individually within an article or sealed packet to be excepted from the HMR. I hope this satisfies your request. Sincerely, c-7'//~~ T.
