Executive summary: How section 232 tariff relief may affect orphan drugs and life sciences

Life sciences companies may have new opportunities to reduce section 232 tariff exposure on orphan drugs, associated pharmaceutical ingredients and certain development-stage imports.

New U.S. Department of Commerce guidance defines which specialty pharmaceutical products may qualify for a 0% tariff rate and identifies pathways based on product eligibility, country of origin and urgent U.S. health needs. The guidance also addresses investigational drugs and certain products imported for clinical trials, research and development, and other noncommercial uses.

For orphan drug manufacturers and importers, the implications can extend beyond finished products to materials used throughout the manufacturing supply chain. Understanding how product status, origin and intended use intersect with the new rules can reveal where tariff relief may be available and where exposure remains.


How orphan drugs may qualify for 0% section 232 pharmaceutical tariff relief

Life sciences companies importing orphan drugs and associated pharmaceutical ingredients may qualify for a 0% section 232 tariff rate under new Commerce Department guidance.

A qualifying orphan drug that originates in a jurisdiction identified by the Commerce Department may receive the 0% tariff treatment without an urgent U.S. health need determination. When that jurisdiction-based pathway is unavailable, an urgent U.S. health need may provide a separate route to tariff relief.

Determining eligibility begins with the product itself. The Commerce Department defines the orphan drug category as a drug or biological product designated for one or more rare diseases or conditions “for which all approved indications … are for one or more such rare diseases or conditions.”

Determining whether an orphan drug qualifies

The following three questions can help companies assess whether an orphan drug may qualify for 0% section 232 tariff treatment:

Section 232 tariff relief for development-stage products

The guidance creates a new Harmonized Tariff Schedule of the United States heading for pharmaceutical articles and associated ingredients that are solely for use in clinical trials, research and development, or other noncommercial applications. Imports meeting the requirements of that provision receive an additional 0% section 232 tariff rate.

Depending on the circumstances, development-stage imports may have other potential tariff-relief pathways, including the U.S. tariff provision for qualifying prototypes.

The provision may be particularly relevant for biotech and other life sciences companies that import materials for clinical trials, research and development, and other activities well before commercialization. Depending on a company’s development and manufacturing processes, those imports can include clinical-trial supplies and materials used in producing investigational therapies.

For companies importing products before commercialization, intended use can therefore be an important factor in identifying where the separate 0% section 232 tariff treatment may apply.

How pharmaceutical ingredients affect section 232 tariff treatment

The section 232 framework extends beyond finished pharmaceutical products. The Commerce Department defines “pharmaceutical articles” to include finished pharmaceutical products, active pharmaceutical ingredients (APIs) and key starting materials for active pharmaceutical ingredients. Inactive ingredients and excipients are excluded from that definition.

For life sciences companies, understanding the treatment of materials throughout the supply chain may require looking beyond finished products. Depending on the company’s products and manufacturing processes, those materials can include:

  • Drug substances
  • Biological materials
  • Specialized intermediates
  • Cell and gene therapy manufacturing inputs

Looking at more than the finished product can help companies identify potential section 232 tariff treatment elsewhere in the manufacturing supply chain. Understanding how those materials are classified and used can clarify where pharmaceutical tariffs may apply and where 0% tariff treatment may be available.

Evaluating potential section 232 tariff relief

Companies can focus on several areas when evaluating how the new guidance may affect their section 232 tariff exposure:

Identify potentially qualifying products

Identifying orphan drugs and other specialty pharmaceutical products that meet the Commerce Department’s definitions can help companies determine which imports may be exempt from the section 232 pharmaceutical tariff relief.

Review regulatory status

Comparing a product’s orphan designation, approved or licensed indications and other regulatory information with the applicable definition can help establish whether it qualifies for the orphan drug category. For qualifying orphan drugs, country of origin then determines whether the jurisdiction-based pathway is available.

Establish country of origin

Determining whether a qualifying product originates in an eligible jurisdiction can establish whether it has access to the jurisdiction-based path to the 0% rate.

Consider intended use

For products imported for clinical trials, research and development or other noncommercial applications, understanding the product’s classification and intended use can help identify imports that may qualify for the separate 0% section 232 tariff treatment provided in the guidance.

Evaluate the urgent U.S. health need pathway

When jurisdiction-based pathway is unavailable, reviewing the information identified by the Commerce Department can help a company determine whether an urgent U.S. health need request may provide a separate route to tariff relief.

Organize supporting information

Bringing together relevant regulatory, product, supply chain and patient information can give companies a clearer view of potential tariff relief and help support an urgent U.S. health need request when that pathway is relevant.

Assessing section 232 pharmaceutical tariff exposure

For orphan drug manufacturers and other life sciences companies, determining whether an imported product qualifies for favorable treatment may be as important as understanding the applicable tariff rate itself. The analysis can depend on the product, its origin and, in some cases, its intended use or an urgent U.S. health need.

Applying those factors across a company’s product pipeline can help identify where tariff relief may be available and where section 232 exposure remains.
