SUPPLEMENTARY INFORMATION:

Request To Add Substance to the List

    (a) Overview. A petition was filed pursuant to Rev. Proc. 2022-26 
(2022-29 I.R.B. 90), as modified by Rev. Proc. 2023-20 (2023-15 I.R.B. 
636), requesting that sodium chlorite be added to the list of taxable 
substances under section 4672(a) of the Internal Revenue Code (List). 
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.
    (b) Petition Content.
    (1) Substance name: Sodium chlorite.
    This substance is also known as NaClO2.
    (2) Petitioner: Occidental Chemical Corporation, an exporter of 
sodium chlorite.
    (3) Proposed classification numbers:
    (i) HTSUS number: 2828.90.0000.
    (ii) Schedule B number: 2828.90.0000.
    (iii) CAS number: 7758-19-2.
    (4) Petition filing dates:
    (i) Petition filing date for purposes of making a determination: 
November 25, 2024.
    (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,

    (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) [rarr] 4 NaClO2 (sodium chlorite) + 2 
H2O (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.
