9903.05.86 Section 301 Forced Labor Exemption Explained

Key Points

• HTS 9903.05.86 is an exemption heading, not a duty heading. It removes or reduces a Section 301 forced labor duty for qualifying goods, rather than imposing any charge of its own.
• The official HTSUS text covers "Articles provided for in subdivision (b) of U.S. note 52 to this subchapter," meaning eligibility is defined entirely by that note.
• The rate column for 9903.05.86 reads "The duty provided in the applicable subheading," confirming no additional duty is assessed under this heading itself.
• This heading belongs to the 9903.05.85-onward block of Section 301 forced labor exemption codes. It rides alongside the underlying Chapter 1-97 classification on the same entry line.
• As of September 19, 2026, eligibility criteria are defined in U.S. note 52, subdivision (b). Confirm current note text in the live HTSUS before filing.

HTS 9903.05.86 is a claim or exemption heading within the Section 301 forced labor tariff framework. Importers whose goods qualify under subdivision (b) of U.S. note 52 to subchapter III of Chapter 99 use this code to assert that those goods are exempt from the Section 301 forced labor duty that would otherwise apply. The heading itself carries no duty; it is the mechanism through which the exemption is claimed on a CBP entry.

What 9903.05.86 is and what program created it

The Section 301 forced labor tariff framework imposes additional duties on goods from certain countries when CBP determines those goods are connected to forced labor practices. Congress authorized Section 301 actions under trade statutes, and the relevant country-specific duty headings in the 9903.05 block (such as the 9903.05.84 Vietnam heading and the 9903.05.85 transit exemption heading) each address a distinct aspect of that framework.

The 9903.05.86 heading sits within the exemption tier of that framework. Instead of assessing a new charge, it signals to CBP that the importer is claiming relief from a Section 301 forced labor duty based on the criteria spelled out in subdivision (b) of U.S. note 52 to subchapter III of Chapter 99. The legal authority and precise product or country scope of that subdivision are set out in U.S. note 52 itself, not in the heading's rate column.

Scope of the exemption: what subdivision (b) of U.S. note 52 covers

The official HTSUS heading text for 9903.05.86 reads: "Articles provided for in subdivision (b) of U.S. note 52 to this subchapter." Every eligibility condition, including which goods qualify, which countries of origin are in scope, and any procedural requirements, is located in that note subdivision, not in the heading description itself.

Because the facts available as of September 19, 2026, do not reproduce the full text of subdivision (b) of U.S. note 52, importers and brokers must read that note directly in the current Harmonized Tariff Schedule (hts.usitc.gov) before determining whether a specific shipment qualifies. The note text can and does change when the program is updated; always pull the live schedule rather than relying on a cached or printed version.

How the rate works: no additional duty

The HTSUS general-column rate for 9903.05.86 is "The duty provided in the applicable subheading." This language is the standard formulation used for exemption and exception headings in Chapter 99. It means:

• 9903.05.86 does not add any percentage on top of the underlying Chapter 1-97 duty or any other applicable Section 301 duty.
• The importer pays only the duty that the underlying, correctly classified Chapter 1-97 subheading requires, once the exemption is properly claimed.
• The exemption may eliminate or reduce a Section 301 forced labor surcharge that would otherwise stack on top of the normal duty. The specific reduction depends on U.S. note 52, subdivision (b).

If you are trying to model total landed-cost impact, use the duty calculator with the underlying Chapter 1-97 subheading as the base rate and apply 9903.05.86 as the exemption overlay.

How 9903.05.86 appears on a customs entry

Chapter 99 codes never stand alone on a CBP entry. When an importer claims 9903.05.86, the entry presents two lines for the same merchandise:

1. The standard Chapter 1-97 classification line, carrying the goods' normal description and column 1 duty rate.
2. The 9903.05.86 overlay line, referencing the exemption and carrying the "duty provided in the applicable subheading" rate notation.

CBP's Automated Commercial Environment (ACE) system reads both lines together. The 9903.05.86 line is what tells ACE to apply the exemption rather than the full Section 301 forced labor surcharge. Omitting the Chapter 99 line means the exemption is not claimed and the surcharge will be assessed. Brokers should confirm the correct entry format with current CBP guidance before submission.

Interaction with other tariff provisions

Section 301 forced labor duties stack on top of existing duties: the base Column 1 general rate, any applicable antidumping or countervailing duty (AD/CVD) orders, and any other Section 301 tariffs that may apply to the same goods from the same country. The 9903.05.86 exemption claim, if valid, relieves the forced labor component of that stack. It does not affect any of the other layers.

Importers should also be aware that other country-specific forced labor duty headings operate in parallel. For example:

• 9903.05.81 addresses the United Kingdom at a 10% rate.
• 9903.05.82 addresses Uruguay at 12.5%.
• 9903.05.83 addresses Venezuela at 12.5%.
• 9903.05.84 addresses Vietnam at 12.5%.

Confirm with a broker which duty heading applies to the country of origin before claiming any exemption. An incorrectly claimed exemption will expose the importer to a duty underpayment and potential penalties.

What importers should do

• Read U.S. note 52, subdivision (b) in the live HTSUS. Go to hts.usitc.gov, navigate to Chapter 99, subchapter III, and read the current text of note 52(b) before filing any entry claiming this exemption.
• Verify the underlying Chapter 1-97 classification first. The 9903.05.86 overlay is only valid when paired with a correctly classified base subheading. If classification of the underlying goods is uncertain, resolve it before addressing the Chapter 99 claim. See our guide on CBP tariff classification general rules of interpretation.
• Include both the Chapter 1-97 line and the 9903.05.86 line on the entry. Missing the overlay line means the exemption is not claimed and the forced labor duty will be assessed.
• Review your bond coverage. If CBP challenges the exemption claim and issues a demand for the forced labor duty, your continuous bond must be sufficient to cover the exposure. See our coverage of customs continuous bond requirements.
