Petition Filed to Add Cellulose Acetate to List of Chemical Substances Subject to Superfund Excise Tax

The Internal Revenue Service (IRS) announced on March 16, 2023, that it received a petition requesting that cellulose acetate (degree of substitution (DS) = 1.5-2.0) be added to the list of taxable substances under Section 4672(a) of the Internal Revenue Code. 88 Fed. Reg. 16307. The petitioner is Celanese Ltd., an exporter of cellulose acetate (DS = 1.5-2.0). According to the notice, cellulose acetate (DS = 1.5-2.0) “is made from cellulose (wood pulp) and methane. The production process is a reaction of cellulose (from wood pulp) with acetic anhydride, normally using a solvent such as acetic acid and a strong acid such as sulfuric acid as a catalyst.” The petition covers cellulose acetate (DS = 1.5-2.0), “commonly referred to as cellulose diacetate. Cellulose acetate in this range generally has similar properties. The petition uses the lowest end of the range cellulose acetate DS = 1.5 to demonstrate that >20% of the substance is made from taxable chemicals, and the midpoint cellulose acetate DS = 1.75 to calculate the tax rate for the entire range.” Comments and requests for a public hearing are due May 15, 2023.
