The Law Offices of Michael A. Capuzzi 63 14 North Wyndwood Drive Crystal Lake, IL 600 14 Ref. No. 08-0294 Dear Mr. Capuzzi: This is in response to your letter dated December 1, 2008, requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 17 1 - 1 80). Specifical!~, you ask for confirmation of your understanding of the labeling requirements for limited quantities of corrosive materials. In your letter, you state a typical shipment consists of seven boxes, containing a total of 84, one-half pound jars of a material described as "Corrosive solid, n.0.s. (Zinc chloride, lithium chloride-anhydrous mixture), UN 1759, PG 11" and two boxes containing a total of 24, thirty- two ounce bottles of a material described as "Corrosive liquid, n.0.s. (Zinc chloride, Hydrochloric acid), UN 1760, PG 111." The nine boxes are shipped together on a shrink wrapped pallet. The HMR provide exceptions for limited quantities of Class 8 materials, depending on how they are packaged and transported. Section 173.154(b) authorizes Class 8 Packing Group I1 materials to be transported as a limited quantity when placed in inner packagings with a capacity of up to 1.0 L (0.3 gal) for liquids or 1.0 kg (2.2 pounds) for solids placed in a strong outer packaging. Class 8 materials meeting Packing Group 111 may be transported as a limited quantity when placed in inner packagings of a capacity of up to 5 L (1.3 gallons) for liquids or 5 kg (1 1 pounds) for solids placed in a strong outer packaging. The completed package must not exceed 30 kg (66 pounds). When complete, the package must conform to the general packaging requirements prescribed in $ 5 173.24 and 173.24a. When transported by aircraft, the Class 8 material must be authorized for transport on board passenger-carrying aircraft, and the package must conform to the general requirements for transportation by aircraft prescribed 5 173.27. Limited quantity packages are excepted from labeling, unless transported by aircraft, and placarding, as prescribed in Subparts E and F of Part 172. Packages containing limited quantities must be marked in accordance with Subpart D of Part 172 and the shipping paper must include the words "Limited Quantity" or "Ltd Qty" following the basic description.#

Page 2Based on the information you provided, the nine boxes placed onto a pallet and surrounded in shrink wrap would meet the definition of an overpack. Authorized packages containing hazardous materials may be offered in an overpack when they meet the requirements of tj 173.25. The overpack must be marked with the proper shipping name and identification number and labeled as applicable, unless the markings and labels representative of each hazardous material in the overpack are visible. I hope this satisfies your inquiry. If we can be of further assistance, please contact us. Sincerely, F0f Charles E. Betts Chief, Standards Development Office of Hazardous Materials Standards#

Discussion - Labeling of the Packaginp and Shipping Boxes Harris Products Group Al-Braze 1070 Flux, Part JW-1070112 The Harris Products Group Al-Braze 1070 flux (hereinafter "Al-Braze flux") is a powdered brazing flux. The imported Al-Braze flux is packaged in one-half pound jars for retail sale. Attached for your ready reference is a catalog page showing a representative sample jar of Al-Braze flux. As outlined in Section One of the Material Safety Data Sheet (hereinafter "MSDS"), the chemical name of the Al-Braze flux is "Alkali Metal Halide Powder." Section Fourteen of the MSDS lists the proper shipping name as "Corrosive Solid, n.0.s." This section of the MSDS states that the Al-Braze flux has a hazard class number and description of "8 (Corrosive)," the UN Identification Number of "UN 1759," and the packing group as "11." Section Fourteen of the MSDS also states the Department of Transportation (hereinafter "DOT") label required for the Al-Braze flux is "Corrosive." A copy of the MSDS for the Al-Braze flux is included for your ready reference. Section 172.400(a) of the DOT regulations (49 CFR 9 172.400(a)) states in pertinent part: Except as specified in $1 72.400a, each person who oflers for transportation or transports a hazardous material in any of the following packages ..., shall label the package ... with labels spec$ed for the material in the $1 72.101 table and in this subpart: (I) A non-bulk package; *** (5) An overpack ... which contains apackage for which labels are required ...; For products having a hazard class of "8," the label required by Section 174.400(b) is "Corrosive."

(P)ackaging which has: (1) A maximum capacity of 450 L (1 19 gallons) or Iess as a receptacle for a liquid; (2) A maximum net mass of 400 kg (882 pounds) or Iess and a maximum capacity of 450 L (1 19 gallons) or Iess as a receptacle for a solid; or (3) A water capacity of 454 kg (1 000pounds) or Iess as a receptacle for a gas ... Section 17 1.8 of the DOT regulations further defines "packaging" as: ...(A ) receptacle and any other components or materials necessary for the receptacle to perform its containment function in conformance with the minimum packaging requirements ... "Receptacle" is defined by Section 171.8 as "...a containment vessel for receiving and holding materials. " The retail jar for the Al-Braze flux satisfies the definition of "packaging" in that the jar serves as the containment receptacle for the one-half pound quantity of corrosive flux. Given that each of the one-half pound Al-Braze flux packaging falls under the maximum limits set-forth for the definition of non-bulk packaging, the subject goods would also satisfy the definition of "non- bulk packaging" and would initially appear to be subject to the labeling requirements of 49 CFR 5 172.400(a).

Examples of overpacks are one or more packages ...p laced in aprotective outer packaging such as a box or crate. Section 171.8 of the DOT regulations defines "package" as " ... packagingplus its contents." As we have already established supra that the jar for the Al-Braze flux satisfies the definition of "packaging," the jar containing the Al-Braze flux satisfies the definition of "package." Section 172.8 of the DOT regulations defines "Outer packaging" as: ... (T)he outermost enclosure of a composite or combination packaging together with any absorbent materials, cushioning and any other components necessary to contain and protect inner receptacles or inner packagings. Section 171.8 of the DOT regulations defines "combination packagings" as: ... (A) combination of packaging, for transport purposes, consisting of one or more inner packagings secured in a non-bulk outer packaging. "Inner packaging" is defined by Section 171.8 of the DOT regulations as " ... apackaging for which an outer packaging is required for transport. .." The shipping box clearly satisfies the definition of an "overpack" given that the box provides protection of, and "convenience in handling," the twelve individuals packaging jars of Al-Braze flux contained therein. To summarize, the jars for the Al-Braze flux satisfy the definition of inner packaging, the jar containing the Al-Braze flux satisfies the definition of a package, and the twelve-jar box of Al-Braze flux satisfies the definition as an outer packaging. Therefore, the box containing the subject goods would also satisfy The Law Offices of Michael A. Capuzzi 6314 North Wyndwood Drive Crystal Lake, IL 60014 Tel: 815-479-5260 Fax: 815-479-1904#

" (Emphasis added). It has been established that the individual jars of Al-Braze flux satisfies the definition of a "package" and that the box containing the twelve jars satisfies the definition of an "overpack." The critical regulatory labeling requirement of Section 174.400(a)(5) is that the overpack must contain packages "for which labels are required" in order for the overpack itself to be required to be labeled. As the individual packages of Al-Braze flux are excepted from the labeling requirements of Section 174.400 by Section 173.154(b) of the DOT regulations, the overpack does not contain packages "for which labels are required." Therefore, the twelve-jar boxes of Al-Braze flux are exempt from the hazardous materials labeling requirements of Section 172 of the Department of Transportation regulations.

Page 18( A P U Z Z I T R A D E L A W As the individual packages of Al-Braze flux and Stay-Clean flux are excepted from the labeling requirements of Section 174.400 by Section 173.154(b) of the DOT regulations, the overpack, i.e. the shrink-wrapped pallet, does not contain packages "for which labels are required." Therefore, the shrink-wrapped pallet containing the twelve-jar boxes of Al-Braze flux and the twelve- bottle boxes of Stay-Clean flux are exempt from the hazardous materials labeling requirements of Section 172 of the Department of Transportation regulations. IV. Discussion - Labeling of Boxes if Pallet is Labeled The final question involves what, if any, labeling is required on the packagings and overpack shipping boxes if the shrink-wrapped pallet overpack does contain labeling, e.g. "Corrosive" label. Because the goods originate in Mexico, the packagings, packages, and overpacks, including the shrink- wrapped pallet, must conform to the hazardous materials labeling requirements for Mexico; these labeling requirements may be different than that of the PHMSA. For example, the shrink-wrapped pallet may be required contain the appropriate "Corrosive" labeling for purposes of transportation in Mexico even though this labeling is not required by the PHMSA regulations. ' Section 5.1.2.1 of the "United Nations Recommendations on the Transportation of Dangerous Goods" states, in pertinent part: An overpack shall be ... labeled, as required for packages by Chapter 5.2, for each item of dangerous goods contained in the overpack unless marking and labeling representative of all dangerous goods in the overpack are visible. ' 49 CFR §172.401(a) states that a package may not bear a label required by the PHMSA regulations unless: 1) The package contains a material that is a hazardous material; and 2) The label represents a hazard of the hazardous material in the package. As was established in Section 11, the subject Al-Braze flux and Stay-Clean flux are "hazardous materials." As such, any labeling that may be placed on the packages or overpacks, including the shrink-wrapped pallet, said labeling being excepted by regulation, would not be in violation of 49 CFR §172.40l(a).

Page 19f f l l ( H A E 1 ( A P U Z Z I T R A D E L A W The controlling requirements for the labeling of hazardous materials in the United States are found in the PHMSA regulations and not the UN Recommendations. As the subject packages and overpacks, including the shrink-wrapped pallet, are exempt from labeling under the PHMSA regulations, there is no labeling requirement placed on the packages or shipping box overpacks if the overpack pallet is labeled in accordance with the UN Recommendations. To summarize, if the shrink-wrapped overpack is labeled in accordance with the UN Requirements, the packaging and shipping boxes of the limited quantities of the subject goods are still exempt from labeling by regulation for the reasons reviewed supra. 111. Conclusion Based upon our understanding of the PHMSA requirements and a plain reading of the corresponding regulations, our position for each point is as follows: 1) What labeling, if any, of the packagings and shipping boxes is required under the PHMSA regulations? For reasons reviewed supra, the jars of Al-Braze powdered flux and bottles of Stay-Clean liquid flux are exempt from the labeling requirements of Section 172 of the Department of Transportation regulations. For reasons reviewed supra, the overpack boxes of the Al-Braze powdered flux and the overpack boxes of the Stay-Clean liquid flux are exempt from the labeling requirements of Section 172 of the Department of Transportation regulations. 2) What labeling, if any, is required for the shrink-wrapped pallet? For reasons reviewed supra, the overpack shrink-wrapped pallet containing the boxes of the Al-Braze powdered flux and the overpack boxes of the Stay-Clean liquid flux is exempt from the labeling requirements of Section 172 of the Department of Transportation regulations.

Page 20f f l l ( H A E 1 ( A P U Z Z I T R A D E L A W 3) If the pallet is labeled, what labeling requirements, if any, are then placed on the packages and overpack shipping boxes as a result of said pallet labeling? For reasons reviewed supra, the jars of Al-Braze powdered flux and bottles of Stay-Clean liquid flux and the overpack boxes containing the same remain exempt from the labeling requirements of the Department of Transportation regulations even when the overpack shrink-wrapped pallet is labeled, for example, in accordance with the UN Recommendations.
