The petition requesting the addition of sodium chlorite to the List is based on weight and contains the information detailed in paragraph (b) of this document. The information is provided for public notice and comment pursuant to section 9 of Rev. Proc. 2022-26. The publication of petition information in this notice of filing is not a determination and does not constitute Treasury Department or IRS confirmation of the accuracy of the information published.

                    This substance is also known as NaClO2.                

                    (2)                     *Petitioner:*                     Occidental Chemical Corporation, an exporter of sodium chlorite.

                    (ii)                     *Petition filing date for purposes of section 11.02 of Rev. Proc. 2022-26, as modified by section 3 of Rev. Proc. 2023-20:*                     July 1, 2022.                

                    (5)                     *Description from petition:*                     Sodium chlorite, a solid (crystals), is used in control of biological activity in potable and non-potable water applications. Additional applications include textile bleaching and disinfection of meat processing facilities.                

Sodium chlorite is made from sodium hydroxide and chlorine. Taxable chemicals constitute 75.87 percent by weight of the materials used to produce this substance.

                    (6)                     *Process identified in petition as predominant method of production of substance:*                     The predominant process for manufacture of sodium chlorite is electrolytic production of NaClO3                     followed by hydrochlorination with wet acid with byproduct chlorine and hydrogen used in manufacture of acid. This substance is produced as a pure component, not a mixture, though it may be sold as an aqueous liquid.                

                    (7)                     *Stoichiometric material consumption equation, based on process identified as predominant method of production:*

                    2 Cl2                     (chlorine) + 4 NaOH (sodium hydroxide) + 3 O2                     (oxygen) → 4 NaClO2                     (sodium chlorite) + 2 H2                    O (water)                

                    (8)                     *Tax rate calculated by Petitioner, based on Petitioner's conversion factors for taxable chemicals used in production of substance:*

                    (i)                     *Tax rate:*                     $2.35 per ton.                

                    (ii)                     *Conversion factors:*                     0.39 for chlorine, 0.44 for sodium hydroxide.                

                    (9)                     *Public docket number:*                     IRS-2025-0011.
