Daly's Wood Finishing Products — Hazardous Materials Safety Interpretation

Page 11200 New Jersey Avenue, SE Washington, DC 20590 U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration July 24, 2025 Courtney Ostbye Director of Operations Daly’s Wood Finishing Products A Division of Farwest Paint Mfg. Co 4522 S. 133rd St Tukwila, WA 98168 Reference No. 25-0011 Dear Ms. Ostbye: This letter is in response to your January 21, 2025 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the segregation requirements of a two-component wood bleach solution. You state that your company manufactures and markets a wood bleach solution comprising both “UN1824, Sodium hydroxide solution, 8, II”— which is referred to as bleach solution A—and “UN2014, Hydrogen peroxide, aqueous solution, 5.1 (8), II”—which is referred to as bleach solution B. You state that each component is packaged individually in a pint, quart, or gallon plastic bottle. You further state the pint and quart-sized plastic bottles are enclosed together in the same industrial polyethylene bags, while the gallon-sized bottles are packaged separately in polyethylene bags; and then, in both cases, the components are packaged together in United Nations (UN) fiberboard boxes. Lastly, you state that these components are designed to be mixed by the end-user (i.e., customer) and pose no risk of combustion, evolution of considerable heat, evolution of flammable or poisonous gases or vapors, or the formation of corrosive or unstable substances when mixed. You ask does the segregation requirements in § 176.83(b) of the HMR and Chapter 7.2 of the International Maritime Dangerous Goods (IMDG) Code apply to the components of this kit? You are correct in that the segregation requirements in the table in § 176.83(b) indicate that these two components would not be allowed in the same shipping container, and therefore they would not be allowed in the same outer packaging. However, one of the provisions for the segregation requirements is found in § 176.83(a)(4)(ii), where it states that segregation is not required between hazardous materials of different classes which comprise a group of substances that do not react dangerously with each other. That provision goes on to list some materials that are grouped by compatibility. It should be noted that there may be additional groups of materials that are compatible and do not react dangerously with each other that are not listed in paragraph#

Page 2(a)(4)(ii)(A) through (C), even when segregation applies in accordance with § 176.83(b). The IMDG Code contains a similar provision in Section 7.2.6.3.2. Additionally, all packagings of hazardous materials must comply with § 173.21(e), which states that it is forbidden to offer for transportation “a material in the same packaging, freight container, or overpack with another material, the mixing of which is likely to cause a dangerous evolution of heat, or flammable or poisonous gases or vapors, or to produce corrosive materials.” I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, T. Glenn Foster Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division#

Daly's Wood Finishing Products A Division of Farwest Paint Mfg Co 4522 S 133d St Tukwila, WA 98168 January 21, 2025 Office of Hazardous Materials Standards US Department of Transportation 1200 New Jersey Ave SE Washington, DC 20590 RE: Request for Letter of Interpretation/Exemption To Whom It May Concern: We manufacture and market a two component Wood Bleach Solution. The components of our Wood Bleach are part "A", a Sodium Hydroxide Solution and part "B", a Hydrogen Peroxide Aqueous Solution. Each component is packaged in pint, quart and gallon HDPE, high density polyethylene, bottles. All bottles are HIS with Vented CRC caps and then enclosed in 2mil industrial poly bags. The pint and quart bottles are enclosed together and the gallon kits are enclosed separately. All components are then packaged in UN specified heavy weight fiberboard cartons. Should the two components leak and combine they pose no risk of reacting dangerously with each other. Our A&B Wood Bleach Solution is specifically made to mix together, through proprietary formulation, and does not cause any external reaction when mixed together. Our two part Wood Bleach Solution will not cause combustion, evolution of considerable heat, evolution of flammable or poisonous gases or vapors, or the formation of corrosive or unstable substances. The two components combined are less dangerous than each component individually. In fact, our Bleach Solution "B" has a subsidiary hazmat number of 8 which is the same as the Bleach Solution "A". Attached you will find the following SDS Sheets: • Bleach Solution "A" (Product Code 17010) • Bleach Solution "B" (Product Code 17110) I have also attached a letter of interpretation given to our direct competitor Wood Kote. I have attached their SDS sheets as well and you will see they are nearly identical. Our concern is the same as Wood Kote's, addressed in your April 17, 1998 letter. We want to be able to make domestic and international freight and marine shipments with our two components packaged together. 4522 S. 133rd ST., TUKWILA, WA 98168 ph 206.244.8844 fx 206.246.7691 toll-free 800.727.9694 w DALYSWOODFINISHES.COM#

We would like to have a clarification addressed to Daly's Wood Finishing Products & Farwest Paint Mfg Co directly to present to shipping authorities. We would like to request for the USDOT to provide a clarification letter which states that our Wood Bleach Solution components are compatible for shipment together and therefore the segregation requirements enumerated in the IMDG Code page 0129 15.1.16 and 49 CFR 176.83(b) in accordance with the hazardous material segregation table, do not apply to our A&B Wood Bleach Solution.

Velikanje President Wood Kote Products, Inc 8000 N.E. 14t Place Portland, OR 97211 1 Dear Mr. Velikanje: This is in response to your letter of October 16, 1997, regarding the packaging of a two component wood bleach kit consisting of an aqueous solution of hydrogen peroxide (28%) and an aqueous solution of sodium hydroxide with a buffer of silicic acid. You request clarification under the provisions of the Hazardous Materials Regulations (HMR; 49 CPR Parts 171-180). Specifically, you asked if a two part kit consisting of one inner container of a material described as Hydrogen peroxide, aqueous solution, 5.1, UN 2014 with a Class 8 subsidiary hazard, and one inner container of a material describe as Sodium hydroxide solution, 8, UN 1824, PG II may be placed in the same outside packaging for transport by vessel. You expressed concern that ocean carriers will not accept these shipments although they have been prepared in accordance with the HMR and the International Maritime Dangerous Goods (IMGD) Code. Yes, these materials may be packaged together in the same outside package provided they are in accordance with 49 CFR 173.21 (e). As indicated in paragraph 3.6 in Annex I of the General Introduction to the IMDG Code, Amendment 28 (see IMDG Code page 0509), a corresponding provision specifies that materials may not be packaged together in the same outer packaging with other materiai if they react dangerously to each other and cause combustion and/or evolution of considerable heat, evolution of flammable, poisonous or asphyxiate gases, or the formation of corrosive or unstable substances. In addition, it is the shippers responsibility to ensure that your materials are properly packaged, marked and labeled. Each material within the package, must be described on the shipping paper and marked on the outside package. The package must be labeled with a Division 5.1 label and a Class 8 label for the primary hazard of the materials. • I hope that this information is helpful. If you need further assistance, please contact us. Sincerely, DelmerF. Billings Chief, Regulations Development Office of Hazardous Materials Standards#
