SUPPLEMENTARY INFORMATION:
Request To Add Substance to the List
[top] (a) Overview. A petition was filed pursuant to Rev. Proc. 2022-26 (2022-
(b) Petition Content.
(1) Substance name: acrylonitrile butadiene styrene ((C 3 H 3 N) a -(C 4 H 6 ) b -(C 8 H 8 ) s ; a = 0.16, b = 0.10, s=0.74).
(2) Petitioner: Trinseo LLC, an importer and exporter of acrylonitrile butadiene styrene ((C 3 H 3 N) a -(C 4 H 6 ) b -(C 8 H 8 ) s ; a = 0.16, b = 0.10, s=0.74).
(3) Proposed classification numbers:
(i) HTSUS number: 3903.30.0000 (Pellets).
(ii) Schedule B number: 3903.30.0000 (Pellets).
(iii) CAS number: 9003-56-9.
(4) Petition filing dates:
(i) Petition filing date for purposes of making a determination: February 14, 2025.
(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: March 1, 2024.
(5) Description from petition: According to the petition, acrylonitrile butadiene styrene ((C 3 H 3 N) a -(C 4 H 6 ) b -(C 8 H 8 ) s ; a = 0.16, b = 0.10, s=0.74), also referred to as ABS, is a thermoplastic terpolymer of acrylonitrile, butadiene, and styrene. It is used for injection molding and thermoforming into plastic articles.
Acrylonitrile butadiene styrene ((C 3 H 3 N) a -(C 4 H 6 ) b -(C 8 H 8 ) s ; a = 0.16, b = 0.10, s=0.74) is made from propylene, ammonia, butadiene, benzene, and ethylene. Taxable chemicals constitute 92.40 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 method of producing acrylonitrile butadiene styrene ((C 3 H 3 N) a -(C 4 H 6 ) b -(C 8 H 8 ) s ; a = 0.16, b = 0.10, s=0.74) is through free radical, random copolymerization of 100% of the acrylonitrile, butadiene, and styrene monomers. Low levels of unreacted monomers remain bound within the polymer matrix as "residual" components of the product as sold or imported.
(7) Stoichiometric material consumption equation, based on process identified as predominant method of production:
a C 3 H 6 (propylene) + a NH 3 (ammonia) + 3/2a O 2 + b C 4 H 6 (butadiene) + s C 6 H 6 (benzene) + s C 2 H 4 (ethylene) ? (C 3 H 3 N) a -(C 4 H 6 ) b -(C 8 H 8 ) s (ABS) + 3a H 2 O + s H 2
(8) Tax rate calculated by Petitioner, based on Petitioner's conversion factors for taxable chemicals used in production of substance:
(i) Tax rate: $9.90 per ton.
(ii) Conversion factors: 0.07 for propylene, 0.03 for ammonia, 0.06 for butadiene, 0.64 for benzene, and 0.23 for ethylene.
(9) Public docket number: IRS-2025-0030.
