9903.05.89: Pharmaceutical Articles Section 301 Forced Labor Exemption

Key Points

• HTS 9903.05.89 is an exemption heading, not a duty-adding code: it removes or reduces the Section 301 forced labor duty for qualifying pharmaceutical articles.
• The official heading covers "articles for use in pharmaceutical applications, as provided for in subdivision (e) of U.S. note 52 to this subchapter."
• The rate column reads "the duty provided in the applicable subheading," meaning your regular Chapter 1-97 duty still applies; the Section 301 forced labor surcharge is what this heading displaces.
• Eligibility is defined by U.S. note 52(e) to Chapter 99, which you must read in full before claiming this heading on an entry.
• The facts in this article are as of September 20, 2026; confirm current text against the live HTSUS before filing.

HTS 9903.05.89 is a Chapter 99 exemption heading that lets qualifying importers of pharmaceutical articles sidestep the Section 301 forced labor duty that would otherwise apply to their goods. The heading itself adds no additional duty. Instead, it signals to CBP that the goods meet the criteria in U.S. note 52(e) to Chapter 99 and are therefore exempt from the forced labor surcharge, leaving only the ordinary Chapter 1-97 rate on the line. Importers of pharmaceutical inputs and finished pharmaceutical articles sourced from countries covered by Section 301 forced labor actions should review this heading carefully.

What 9903.05.89 is and what program it belongs to

Section 301 of the Trade Act of 1974 authorizes additional duties on goods from countries found to engage in unfair trade practices, including the use of forced labor. A separate block of Chapter 99 headings, beginning at 9903.05.85 and continuing into the 9903.06 series, carves out exemptions and exceptions from those forced labor duties for specified categories of goods. HTS 9903.05.89 is one of those carve-out headings.

The official heading text, drawn directly from the Harmonized Tariff Schedule of the United States, reads: "Articles for use in pharmaceutical applications, as provided for in subdivision (e) of U.S. note 52 to this subchapter." The operative phrase is "as provided for in subdivision (e) of U.S. note 52." That note, not the heading itself, defines exactly which pharmaceutical articles are covered. You must read U.S. note 52(e) in the current HTSUS before claiming this code.

Because 9903.05.89 is an exemption heading, it is categorically different from headings like 9903.05.84 (Vietnam, 12.5% Section 301 forced labor duty) or 9903.05.83 (Venezuela, 12.5% duty), which impose additional duties. Claiming 9903.05.89 removes a duty burden rather than creating one.

Scope: which pharmaceutical articles qualify

The heading's product scope is "articles for use in pharmaceutical applications." That phrase is broad on its face, but the operative limiting language is the cross-reference to subdivision (e) of U.S. note 52 to Chapter 99 of the HTSUS. That note controls eligibility completely. The facts block for this article does not reproduce the full text of U.S. note 52(e), so you must retrieve it directly from the HTSUS online to determine whether your specific goods qualify.

Practical questions to answer before claiming 9903.05.89:

• Does your product fall within the article descriptions enumerated in U.S. note 52(e)?
• Is the product classified in a Chapter 1-97 subheading that U.S. note 52(e) covers?
• Is the forced labor duty you are seeking to avoid actually applicable to your goods under the relevant Section 301 action?

If you are uncertain whether your pharmaceutical article qualifies, confirm with your customs broker or check the live HTSUS for the full note text. See also our overview of 2026 tariff codes for broader context on the Chapter 99 landscape.

How the rate works, and what you actually pay

The HTSUS general-column rate for 9903.05.89 reads: "The duty provided in the applicable subheading." This language has a specific meaning in Chapter 99 practice: it tells CBP to collect the ordinary duty from the goods' underlying Chapter 1-97 classification, and nothing more in connection with this heading. The Section 301 forced labor surcharge that would otherwise be collected is waived for goods properly entered under 9903.05.89.

In plain terms: if your pharmaceutical article normally carries a 5% MFN duty under its Chapter 1-97 subheading, you pay 5%. The forced labor Section 301 additional duty does not stack on top. The exemption heading does its work by its presence on the entry, not by stating a separate rate.

How 9903.05.89 stacks with other duties

Chapter 99 exemption headings travel alongside, not instead of, the underlying Chapter 1-97 classification. A typical entry line for a qualifying pharmaceutical article will show:

• The Chapter 1-97 subheading (your product's permanent classification)
• 9903.05.89 (the exemption claim for the Section 301 forced labor duty)

Other Chapter 99 duty-adding codes that may apply to your goods, such as Section 301 trade-remedy duties unrelated to forced labor, are a separate question. This heading exempts only from the specific forced labor duty it was designed to cover. If your goods also carry ordinary Section 301 duties from other actions, those remain in place unless a separate exemption or exclusion applies. Confirm your full duty stack using the duty calculator or with your broker.

The UFLPA (Uyghur Forced Labor Prevention Act) is a distinct legal regime from the Section 301 forced labor duties. Claiming 9903.05.89 does not resolve a UFLPA withhold or rebuttable-presumption finding. For UFLPA issues, see our article on the UFLPA rebuttable presumption.

How to claim the exemption on a customs entry

To claim 9903.05.89, the heading must be reported on the CBP entry alongside the underlying Chapter 1-97 classification. In ACE, this means entering both the regular HTS number and 9903.05.89 on the same line or as a secondary HTS, following CBP's entry instructions for Chapter 99 exemption headings.

Key compliance points:

• Retain documentation supporting the pharmaceutical-use characterization of the goods, since CBP may ask for it at liquidation or during a CF-28 or CF-29 inquiry.
• If an entry has already liquidated without the 9903.05.89 claim and you believe the goods qualified, a protest under 19 U.S.C. 1514 may be available. See our article on CBP protests and challenging liquidation decisions for the process and deadlines.
• Check CBP's CSMS system at cbp.gov for any operational messages specific to this heading or to Section 301 forced labor exemption processing.

Related exemption headings in the same block

HTS 9903.05.89 sits within a series of Section 301 forced labor exemption headings that begin at 9903.05.85. Each heading covers a different product category. Reviewing the adjacent headings can clarify whether your goods belong under 9903.05.89 or a sibling code:

• 9903.05.85: Section 301 Forced Labor Transit Exemption
• 9903.05.86: Section 301 Forced Labor Exemption
• 9903.05.87: Section 301 Forced Labor Exemption
• 9903.05.88: Civil Aircraft Section 301 Forced Labor Exemption

If your goods do not fit the pharmaceutical-application language of 9903.05.89, one of the sibling headings may apply, provided your goods meet that heading's note criteria.

What importers should do

1. Pull U.S. note 52(e) from the live HTSUS and confirm your specific pharmaceutical articles are listed before claiming 9903.05.89 on any entry.
2. Coordinate with your customs broker to ensure ACE entry lines report both the Chapter 1-97 classification and 9903.05.89 correctly, and that supporting pharmaceutical-use documentation is on file.
3. Review past entries where the Section 301 forced labor duty was paid on potentially qualifying pharmaceutical goods and assess whether a protest under 19 U.S.C. 1514 is warranted given applicable deadlines.
4. Monitor CBP's CSMS and the Federal Register for any amendments to U.S. note 52 or to the Section 301 forced labor program that could affect eligibility.
