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), requesting that nylon 6 be added to the list of
taxable substances under section 4672(a) of the Internal Revenue Code
(List). The petition requesting the addition of nylon 6 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: Nylon 6.
(2) Petitioner: AdvanSix Inc., an exporter of nylon 6.
(3) Proposed classification numbers:
(i) HTSUS number: 3908.10.00.
(ii) Schedule B number: 3908.10.0000.
(iii) CAS number: 25038-54-4.
(4) Petition filing dates:
(i) Petition filing date for purposes of making a determination:
November 8, 2023.
(ii) Petition filing date for purposes of section 11.02 of Rev.
Proc. 2022-26: July 1, 2022.
(5) Description from petition: According to the petition, nylon 6,
or poly(caprolactam), is a semicrystalline polyamide that has broad use
in textile fibers, engineering plastics, food packaging films, and
monofilaments. The number ``6'' in nylon 6 refers to the number of
carbon atoms in each polymeric repeat unit. Nylon 6 may be utilized
neat or with functional additives by melt processing into the desired
final form.
Nylon 6 is made from benzene, propylene, ammonia, methane, and
sulfuric acid; however, sulfuric acid is cancelled from the
stoichiometric material consumption equation due to no net consumption/
production. Taxable chemicals constitute 46.64 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 production of nylon
6 is the ``hydrolytically initiated ring-opening polymerization of
caprolactam'' which is also referred to in industry literature as the
``hydrolytic polymerization of nylon 6.'' This process is termed
``hydrolytic'' because water plays a key role in the chemical
mechanism. Nylon 6 is produced almost exclusively through this method
because it is easier to control and better adapted for large-scale
operations.
The hydrolytic polymerization of nylon 6 generally entails heating
a mixture of caprolactam and water to ~270[deg]C in an inert atmosphere
of nitrogen and holding until equilibrium conditions are achieved. The
three principal reactions in this process are summarized below:
1. In the initiation step of the process, the caprolactam ring is
hydrolyzed via ring opening with the addition of one water molecule to
become amino-caproic acid.
2. In the next step of the mechanism, the amino-caproic acid acts
as the initiating species to begin the addition polymerization by ring-
opening of caprolactam.
3. The last major mechanism step of the hydrolytic polymerization
of nylon 6 is the condensation of primary amine and carboxylic acid
chain-ends to form an amide linkage in the now higher molecular weight
polyamide with the simultaneous loss of a water molecule.
(7) Stoichiometric material consumption equation, based on process
identified as predominant method of production:
nC6H6 (benzene) + nC3H6
(propylene) + 2.5nO2 (oxygen) + 0.5nCH4 (methane)
+ 5nNH3 (ammonia) + 2nH2O (water) +
2nSO2 (sulfur dioxide) [rarr]
(C6H11NO)n (nylon 6) +
nC3H6O (acetone) +
2n(NH4)2SO4 (ammonium sulfate) + 0.5
CO2 (carbon dioxide)
Where n indicates the number of repeating units.
(8) Tax rate calculated by Petitioner, based on Petitioner's
conversion factors for taxable chemicals used in production of
substance:
(i) Tax rate: $14.77 per ton.
(ii) Conversion factors: 0.69 for benzene; 0.37 for propylene; 0.75
for ammonia; 0.07 for methane.
(9) Public docket number: IRS-2024-0005.
