No. 04-0083 Export Distribution Supervisor Mallinckrodt Baker Inc. 7001 Bypass Road Paris, KY 40361 Dear Ms. Barron: This responds to your March 18, 2004 letter requesting clarification on the requirement to mark limited quantity packages with the UN identification number within a diamond under section whether the IMDG Code requires packages containing limited quantities to be marked with the 3.4.5.2 of the International Maritime Dangerous Goods (IMDG) Code. Specifically, you ask UN identification number placed within a diamond as specified in 3.4.5.2 of the IMDG Code. The answer is yes. Section 3.4.5.2 of the IMDG Code states that limited quantity packages need not be marked with the proper shipping name but, must be marked with the UN identification number placed within a diamond. In your letter you note that § 172.315 of the Hazardous Materiais Regulations (HMR; 49 CFR. Parts 171-180) allows the UN identification number within a diamond marking as an option but does not require it if the proper shipping name is marked on the box. You ask whether the intent of the IMDG Code is to also allow a similar alternative. No similar alternative exists in the IMDG Code. However, limited quantities of dangerous goods for personal or household use that meet the provisions of section 3.4.7 of the IMDG Code are not required to be marked with the UN identification number within a diamond. I hope this answers your inquiry. Sincerely, Chief, Standards Development Office of Hazardous Materials Standards 040083 ..10% $ 172.315 <<>> tyco Mallinckrodt Baker, Inc. P.O.

This is in the chapter regarding "Limited Quantities", section 3.4.5.1(.2), I am writing to request a DOT interpretation of an IMDG regulation that went into effect Marking & Labeling. provisions of this chapter need not be marked with the Proper Shipping Name of the It states "packages of dangerous goods transported in accordance with the special contents, but shall be marked with the UN Number of the contents placed within a diamond." We are a chemical company and ship roughly 75% of the UN numbered products listed in the Dangerous Goods List. All of our packages ship with a pick ticket label attached that includes the Proper Shipping Name, the hazard class, the UN number, and the packing group. This ticket goes on every box, whether it is a regular hazardous order or a regular order vs. no hazard label for the limited quantity order. All of our hazardous limited quantity order, the only difference being the hazard label being applied for the items are packaged in the correct UN specification packaging, whether they are a regular hazardous order or a limited quantity order. We ship our material worldwide and ship numerous containers and LCL shipments overseas. Because of our extensive product line, and because of the segregation rules for products in 100 gr, 500 gr, or 500 ml size containers, along with the 2.5 ltr and 4 ltr size IMDG (and DOT), we do use the limited quantity rule, as we sell a majority of our We may have an overseas container load that has several different oxidizers, corrosives and flammables. Some of these inner packagings are only 500 ml or 500 gram sizes, as limited quantities based on Column 7 of the Dangerous Goods List. <<>> tyc0 Mallinckrodt Baker, Inc. P.O. Box 800 • Specialty Paris, KY 40362-0800 Products Tele: 859 987-7000 Mallinckrodt Baker Because we have so many diren tens that no clairy as winded quantity, our numbered diamonds on each package, no matter how much information you're giving on One interpretation of the regulation is that no matter what, you've got to have these UN the package. However, the other argument or interpretation is that the statement "need not be marked with the Proper Shipping Name of the contents," means that you do not have to do that, but if you do give all the required shipping information, then you've complied with the IMIDG, which is requiring that a UN Number be on the package. This is a very big issue for us, because to purchase these labels with UN Numbers already in the label for each of the thousands of UN products that we sell, the cost of these labels would end up costing more than the product itself. Because of the compatibility issues, we will need to continue to ship as limited quantities. All of our material is packaged according to DOT regulations. When these products are run in production, if they are classified as a limited quantity by DOT, then no hazard spec packages, but have no hazard label on them. Our bill of ladings that are computer label is put on the box. Therefore these packages are in stock already packaged in UN generated show "limited quantity" in the description line. These same products are is also used as limited quantity for IMDG pulled for International orders, and generally anything used as limited quantity for DOT The DOT states in 172.315 that "a package containing a limited quantity of hazardous materials in not required to be marked with the proper shipping name provided it is marked with the identification (ID) number, preceded by the letters "UN" or "NA", as meet one or the other requirement in order to comply with the DOT regulations. I need applicable." In my interpretation, this reads as an "either-or" situation, you've got to to know if the intent of the IMDG was to actually have an "either-or" requirement also. All we hear about is how everyone is trying to be on the same page when it comes to DOT, IMDG & IATA regulations, and this would be one of those times that I hope everyone is on the same page. Looking forward to your interpretation of this IMDG regulation. Thank you, Conne Barin <<>> tyco P.O.
