Re: Consolidated Premanufacture Notice Submission under TSCA Section 5 by Hanwha International LLC

Dear Sir/Madam: Enclosed you will find a Consolidated Premanufacture Notice (PMN) submitted under Section 5(a)(1) of the Toxic Substances Control Act (TSCA). This Consolidated PMN is being submitted to the U.S. Environmental Protection Agency (EPA or the Agency) by Hanwha International LLC (Hanwha International or the Company) for the four grades of chemical substances identified below: CA Index Name: Multi-walled carbon nanotubes CAS Registry Number: Not registered Trade Name: Hanwha Multi-walled Carbon Nanotubes Grades: CM-95, CM-100, CM-150, and CM-250 TS Number: HMWCN1 This Consolidated PMN submission is made in accordance with the regulations given at 40 CFR 720. We request
Page 1 SANITIZED SUBMISSION

### that the Agency begin review upon receipt. This notice has been created using the EPA’s new e-PMN software and,

as now required under EPA regulations, this notice is being submitted through EPA's Central Data Exchange (CDX). At this time, Hanwha International is also remitting a check in the amount $2,500.00 for the PMN user fee in accordance with the requirements at 40 CFR 700.45(b)(2)(i). This check is being sent to EPA’s Washington Finance Center in St. Louis, MO. Finally, Hanwha International is claiming certain information in the Consolidated PMN as Confidential Business Information (CBI) in accordance with the provisions at 40 CFR 720.80. The Company, however, is not claiming either the chemical identity or company identity as CBI. For all questions regarding the submission of this Consolidated PMN, the technical contact is Mr. John V. Massingale of Greenwich Chemical Consulting, Inc. He is reachable at (561) 578-8110. Sincerely, Kwangho Lee General Manager

Page 35 SANITIZED SUBMISSIONThe new chemical substance is expected to offer the following Pollution Prevention benefits:

(1) The new chemical substance when used as an additive in materials increases the wear and life of the material through the reduction of friction and increase in material strength. This results in extended material and product life, as well as reduced energy consumption. (2) The new chemical substance may be used to enhance the conductivity of electronic devices. This is expected to result in reduced energy consumption and improved energy efficiency and output.
