Modern Authentication of Pharmaceuticals Act of 2025
This bill requires each dose of a pharmaceutical product that is a controlled substance and that is taken orally in solid form (i.e., pills) to include a physical chemical identifier. (Physical chemical identifiers are substances that possess a unique physical or chemical property, such as inks, pigments, flavors, and molecular taggants, that unequivocally identify and authenticate a drug or dosage.) Under the bill, physical chemical identifiers must be included in or on the product and must be machine readable.
The bill applies to products manufactured beginning five years after the bill's enactment.

Based on the full Introduced in House · 2025-02-06 text. This explanation has not received human editorial review. This overview describes the proposal’s major provisions; it does not establish what its real-world effects would be.
What it would do
This bill proposes requiring each dose of a controlled-substance medicine in solid form taken by mouth to contain or carry a machine-readable physical or chemical marker intended to check authenticity. The requirement would cover products manufactured starting five years after enactment. It would also update federal drug supply-chain definitions to recognize these markers and their use in checking authenticity.
Check the sources
(B) a physical chemical identifier shall be included in or on each dose of a product that is— (i) a controlled substance (as defined in section 102 of the Controlled Substances Act); (ii) in solid oral dosage form; and (iii) manufactured on or after the date that is five years after the date of enactment of the Modern Authentication of Pharmaceuticals Act of 2025;
(B) a physical chemical identifier, possessing a unique physical or chemical substance or combination of substances, that— (i) is in or on a product; (ii) is machine readable; and (iii) is intended to authenticate the product or a dosage form thereof.
Section 2 would add a mandatory identifier requirement for every dose of a covered product. All three conditions must apply: the product is a controlled substance under the referenced law, it is in solid oral dosage form, and it was manufactured on or after the five-year anniversary of enactment. The trigger is the manufacturing date; the bill supplies no fixed calendar date.
Check the sources
(a) In general Section 582(a)(9) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360eee–1(a)(9)) is amended—
(B) a physical chemical identifier shall be included in or on each dose of a product that is— (i) a controlled substance (as defined in section 102 of the Controlled Substances Act); (ii) in solid oral dosage form; and (iii) manufactured on or after the date that is five years after the date of enactment of the Modern Authentication of Pharmaceuticals Act of 2025;
The proposed definition of “product identifier” would recognize two alternatives: a standardized graphic containing the product's numerical identifier, lot number, and expiration date in human-readable and machine-readable forms; or a physical or chemical marker in or on the product. The marker must contain a unique substance or combination of substances, be machine readable, and be intended to authenticate the product or its dosage form.
Check the source
(1) Section 581(14) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360eee(14)) is amended to read as follows: (14) Product identifier The term product identifier means— (A) a standardized graphic that includes, in both human-readable form and on a machine-readable data carrier that conforms to the standards developed by a widely recognized international standards development organization, the standardized numerical identifier, lot number, and expiration date of the product; or (B) a physical chemical identifier, possessing a unique physical or chemical substance or combination of substances, that— (i) is in or on a product; (ii) is machine readable; and (iii) is intended to authenticate the product or a dosage form thereof.
The proposed definition of “verification” would recognize both checking a package or case identifier against information assigned by the manufacturer or repackager, and checking whether a product or dosage form is authentic using the physical or chemical marker.
Check the source
(2) Section 581(28) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 360eee(28)) is amended to read as follows: (28) Verification or verify The term verification or verify means— (A) determining whether the product identifier affixed to, or imprinted upon, a package or homogeneous case corresponds to the standardized numerical identifier or lot number and expiration date assigned to the product by the manufacturer or the repackager, as applicable in accordance with section 582; or (B) determining whether a product or a dosage form thereof is authentic using a physical chemical identifier described in paragraph (14)(B).

What this analysis cannot establish
The supplied full text is the introduced version. Its provisions are proposals; the supplied action snapshot does not establish whether the bill later advanced, changed, or became law.
The bundle does not reproduce the surrounding provisions of section 582(a)(9), the existing definitions being replaced, or the referenced definitions of “product” and “controlled substance.” It therefore does not establish the full statutory scope, interaction with existing requirements, or applicable exemptions.
The bill text does not specify new enforcement procedures, penalties, marker approval standards, or a termination date. The surrounding law needed to explain existing administration and enforcement is not supplied.
No member earmark disclosures, committee reports, conference materials, or amendment history are supplied. The Riders & Targeted Benefits review is limited to the introduced text.
