9903.06.08: El Salvador Section 301 Forced Labor Exemption

Key Points

• HTS 9903.06.08 is a Chapter 99 exemption heading, not a duty: it signals that qualifying El Salvador products are exempt from or receive reduced Section 301 forced-labor duties.
• The official heading text limits coverage to articles the product of El Salvador, as provided for in subdivision (j)(7)(ii) of U.S. note 52 to subchapter III of Chapter 99.
• The rate column reads "The duty provided in the applicable subheading," meaning 9903.06.08 carries no additional duty of its own.
• This heading rides on an entry alongside the regular Chapter 1-97 classification line; it does not replace it.
• The product-scope conditions are defined entirely by U.S. note 52, subdivision (j)(7)(ii): confirm your goods meet those conditions before claiming the heading.

HTS 9903.06.08 is a Section 301 forced labor exemption heading for articles the product of El Salvador, as described in subdivision (j)(7)(ii) of U.S. note 52 to subchapter III of Chapter 99. It does not impose a duty. Instead, it functions as a claim that, when properly asserted on an entry, exempts qualifying goods from the Section 301 forced-labor additional duties that would otherwise apply. Importers sourcing covered goods from El Salvador need to understand the heading's scope, how to claim it, and how it interacts with their full duty picture. All facts in this article reflect the HTSUS as of September 26, 2026.

What 9903.06.08 is and why it matters

Chapter 99 of the Harmonized Tariff Schedule of the United States is reserved for special classification provisions, including temporary modifications and program-specific headings. The 9903.06 block contains a series of headings tied to the Section 301 forced-labor duty program. Within that block, some headings impose additional duties on goods from countries subject to those measures; others, like 9903.06.08, provide an exemption or exception for goods that meet specific qualifying criteria.

The authority for this heading is found in U.S. note 52 to subchapter III of Chapter 99, which defines the full scope of the Section 301 forced-labor provisions, including the country-specific and product-specific carve-outs. Subdivision (j)(7)(ii) of that note governs the particular category of El Salvador goods eligible under 9903.06.08.

Because this is an exemption heading, claiming it correctly is what keeps forced-labor additional duties off your entry. Failing to claim it when goods qualify means overpaying. Claiming it when goods do not qualify is a compliance risk. Neither outcome is acceptable, so precision matters.

Scope: which products and which country

Country of origin

Coverage under 9903.06.08 is limited to articles the product of El Salvador. Country of origin must be El Salvador under the applicable CBP origin rules. Goods that merely transit El Salvador, or that are assembled there but do not meet origin criteria, do not qualify. If your supply chain involves El Salvador processing, confirm origin determination with your broker or a CBP ruling before relying on this heading.

Product scope

The product scope is defined exclusively by subdivision (j)(7)(ii) of U.S. note 52 to subchapter III of Chapter 99. The HTSUS heading text does not enumerate individual HTS subheadings; it cross-references the note directly. That means the note itself, not the heading text, controls which goods qualify. Review the current text of U.S. note 52 in the official HTSUS to confirm whether your specific goods fall within subdivision (j)(7)(ii). If the note has been amended since your last review, the current published version controls.

How the rate works

The HTSUS general column rate for 9903.06.08 reads: "The duty provided in the applicable subheading." This language is characteristic of exemption and exception headings throughout Chapter 99. It means 9903.06.08 itself adds zero additional duty. Your duty liability on a qualifying entry is determined entirely by the regular Chapter 1-97 classification and any other applicable provisions, not by this heading.

In practical terms, the effect of correctly claiming 9903.06.08 is to remove the Section 301 forced-labor additional duty that would otherwise be assessed on El Salvador-origin goods covered by the broader forced-labor provisions. The net result is that the importer pays the ordinary column 1 general rate (and any other applicable duties) but not the Section 301 forced-labor surcharge, for goods meeting the note 52(j)(7)(ii) criteria.

How 9903.06.08 appears on a customs entry

Chapter 99 headings do not stand alone on a CBP entry. When you claim 9903.06.08, the entry will show two classification lines for the same shipment:

• Line 1: The regular Chapter 1-97 HTS subheading that classifies the good by its nature (for example, a textile subheading in Chapter 62).
• Line 2: 9903.06.08, the Chapter 99 exemption heading, riding alongside line 1 to flag the forced-labor exemption claim.

CBP's Automated Commercial Environment (ACE) system requires both lines to be present for the exemption to be recognized. Omitting the Chapter 99 line means the system will not apply the exemption automatically. Check the CBP CSMS messages and ACE filing guidance for the current technical instructions on how to report this heading.

Interaction with other tariff provisions

Other Section 301 measures

The 9903.06 block addresses forced-labor-related Section 301 duties specifically. These are distinct from other Section 301 tariff actions on other countries or product categories. Confirm with your broker which Section 301 actions, if any, apply to your goods independent of the forced-labor measures, because 9903.06.08 addresses only the forced-labor component.

Other Chapter 99 provisions

If your goods are also subject to other Chapter 99 provisions (for example, antidumping, countervailing, or Section 232 duties), those provisions operate independently. Claiming 9903.06.08 removes only the forced-labor additional duty it is designed to address. Confirm the full stack of applicable Chapter 99 headings with your broker for every entry involving these goods.

Preferential duty programs

El Salvador is a CAFTA-DR beneficiary. If your goods qualify for CAFTA-DR preference under the regular Chapter 1-97 subheading, that preference applies on the ordinary duty rate. The interaction between CAFTA-DR and the Section 301 forced-labor exemption heading is a question to confirm in the current HTSUS notes and with your broker, as the facts block for this article is silent on that interaction.

Classification precision

Because 9903.06.08 cross-references note 52(j)(7)(ii) by name, the accuracy of your Chapter 1-97 classification directly affects whether your goods fall within the note's product scope. A misclassification in Chapter 1-97 can knock goods out of or into the exemption incorrectly. See our overview of the 2026 tariff code landscape for context on classification discipline this year.

What importers should do

• Pull the current U.S. note 52, subdivision (j)(7)(ii) from the HTSUS at hts.usitc.gov and confirm your El Salvador goods are described there before claiming 9903.06.08 on any entry.
• Verify country-of-origin documentation for every shipment: manufacturer's affidavits, certificates of origin, and production records should clearly support an El Salvador origin determination under CBP rules.
• File both the Chapter 1-97 line and the 9903.06.08 line on every qualifying entry in ACE, and review current CBP CSMS guidance for the correct technical format.
• Audit past entries for El Salvador goods to determine whether the exemption was claimed when it should have been, and consult your broker about protest or prior disclosure options if duties were overpaid.
