G.R. No. 222480 - Avon Products Manufacturing, Inc. vs. Commissioner of Internal Revenue

Avon Products Manufacturing, Inc., a manufacturer of perfumes, toilet waters, splash colognes, and body sprays, uses denatured alcohol as a key raw material.
The Bureau of Internal Revenue (BIR) issued Avon a Permit to Buy/Use Denatured Alcohol on January 7, 2008, which provided an exemption from excise tax provided that the denatured alcohol was used solely in production, but also imposed a condition that any discrepancy between the purchased and received volumes would attract excise tax.

From January to December 2008, Avon purchased a total of 1,309,000 liters of denatured alcohol from its suppliers.
During transit to Avon’s warehouse in Calamba, Laguna, a marginal quantity—specifically 21,163.48 liters—evaporated, leading to a discrepancy between the purchased and received volumes.

The BIR issued a Formal Letter of Demand, assessing deficiency excise tax on the evaporated quantity based on a computation that included a basic tax, a 25% surcharge, deficiency interest, and delinquency interest.
Avon challenged the assessment by filing a protest, which was denied in the Final Decision on Disputed Assessment (FDDA) dated September 1, 2010.
Avon further elevated the issue by filing for review before the Court of Tax Appeals (CTA), initially undergoing a decision by the Second Division on May 16, 2013 which partially modified the assessed amount.

The CTA Second Division denied Avon’s petition for review, upholding the deficiency assessment calculated on the evaporated volume.
Avon’s subsequent motions for reconsideration were denied by both the Second Division and the CTA En Banc, with the latter affirming the modified deficiency assessment in decisions dated March 16, 2015, and January 15, 2016.
Avon advanced the case to the Supreme Court through a Petition for Review on Certiorari, raising several assignments of error regarding the application of tax provisions and administrative regulations.

Avon argued that the CTA erred in ruling that denatured alcohol, which is exempt from excise tax under Section 134 of the National Internal Revenue Code (NIRC), could be subject to tax due to losses incurred during transit.
Avon contested the application of Revenue Regulation (RR) No. 3-2006, asserting it was incorrectly extended from distilled spirits to denatured alcohol.
Additional errors noted included the CTA’s interpretation of the BIR’s permit conditions and the concurrent imposition of deficiency and delinquency interest amounts.

Whether the evaporated volume of 21,163.48 liters of denatured alcohol, which did not undergo rectification or distillation, should attract deficiency excise tax.
Whether the application of RR No. 3-2006—specifically Section 22 dealing with losses on distilled spirits—is proper when applied to a tax-exempt article such as denatured alcohol.
Whether the condition imposed in the BIR permit contradicts the tax exemption provided under Section 134 of the NIRC.
Whether the simultaneous imposition of deficiency and delinquency interest is legally justifiable and consistent with the statutory scheme, given that the evaporated product did not reach the stage of reprocessing to a distilled spirit.
