9903.06.07: El Salvador Section 301 Forced Labor Exemption

Key Points

• HTS 9903.06.07 is an exemption claim heading, not a duty-imposing heading: claiming it removes or reduces a Section 301 forced labor duty on qualifying articles from El Salvador.
• The rate shown in the HTSUS general column is "the duty provided in the applicable subheading," meaning the heading itself adds no extra charge.
• Eligibility is defined in subdivision (j)(7)(i) of U.S. Note 52 to Subchapter III of Chapter 99, which controls which El Salvador products qualify.
• The heading must appear on your entry alongside the regular Chapter 1-97 classification line; it does not replace it.
• Confirm current eligibility conditions against the live HTSUS and with your broker, as the Section 301 forced labor framework can be updated by executive action.

HTS 9903.06.07 is a Chapter 99 exemption claim heading under the Section 301 forced labor framework. As of September 25, 2026, it covers articles that are the product of El Salvador, as provided for in subdivision (j)(7)(i) of U.S. Note 52 to Subchapter III of Chapter 99. Importers of qualifying El Salvador goods use this heading to claim relief from the Section 301 forced labor surcharge that would otherwise apply. The heading carries no duty of its own: it functions as a gate, and the duty owed is simply whatever the underlying Chapter 1-97 subheading requires.

What 9903.06.07 is and why it matters

Chapter 99 of the Harmonized Tariff Schedule of the United States (HTSUS) is reserved for special classification provisions, including both duty-imposing and duty-relieving headings. The 9903.06 block houses Section 301 forced labor exemption headings. These headings do not add duties; instead, they signal to U.S. Customs and Border Protection (CBP) that the importer is asserting a specific exemption from a forced labor-related Section 301 surcharge.

Heading 9903.06.07 is the El Salvador-specific exemption within that block. Without the claim, goods from El Salvador that fall within the Section 301 forced labor action's scope would be subject to the applicable surcharge. With a valid claim under 9903.06.07, that surcharge is removed or reduced, and only the ordinary Chapter 1-97 duty applies.

Similar exemption headings exist for other countries. For context on how the same framework operates for other origins, see the related articles on Guatemala (9903.06.04), Cambodia (9903.06.03), and Malaysia (9903.06.01).

Products and country scope

Country of origin: El Salvador

The exemption applies only to articles that are the product of El Salvador. Country of origin for this purpose follows standard CBP origin rules. Goods that are merely transshipped through El Salvador, or that undergo only minimal processing there, will not satisfy the origin requirement. Confirm the origin analysis with your broker before claiming this heading.

Product scope: U.S. Note 52, subdivision (j)(7)(i)

The official heading text references subdivision (j)(7)(i) of U.S. Note 52 to Subchapter III of Chapter 99. That note defines the precise product scope: only goods described in that subdivision qualify. The HTSUS note is the controlling legal text. Review it directly in the official HTSUS at hts.usitc.gov to determine whether a specific product falls within (j)(7)(i). The facts block does not enumerate individual product categories, and this article does not extrapolate beyond the heading's text.

How the rate works: no additional duty

The HTSUS general column rate for 9903.06.07 reads: "The duty provided in the applicable subheading." This is the clearest possible signal that the heading imposes nothing on its own. The duty owed is entirely determined by the importer's Chapter 1-97 classification, the same rate that would apply in the absence of any Section 301 action. The exemption heading's job is to strip away the Section 301 forced labor surcharge, leaving only the baseline duty.

This structure differs from duty-imposing Chapter 99 headings such as Section 232 or ordinary Section 301 tariff headings, which stack an additional percentage on top of the Chapter 1-97 rate. Here, the stacking goes in the opposite direction: the claim heading eliminates a charge rather than adding one.

Claiming the exemption on a CBP entry

Dual-line reporting

Chapter 99 exemption headings ride alongside, not instead of, the regular Chapter 1-97 classification. On your CBP entry, you will report two HTS numbers for each line claiming this exemption:

• The standard Chapter 1-97 subheading that classifies the article by its nature.
• 9903.06.07 as the secondary Chapter 99 claim heading.

The liquidated duty is calculated from the Chapter 1-97 rate. The 9903.06.07 line signals to CBP that the Section 301 forced labor surcharge should not be assessed.

Documentation and recordkeeping

CBP may request documentation supporting the country-of-origin determination and the product-scope claim under subdivision (j)(7)(i). Maintain origin records, supplier certifications, and any internal classification analysis in your records. The standard five-year record-retention rule applies. For guidance on how CBP rulings interact with port-level decisions, see CBP Ruling Letter Binding vs Port Decision: Which Controls.

Interaction with other tariff provisions

Goods from El Salvador may also be subject to other Chapter 99 provisions, including Section 232 steel and aluminum tariffs, antidumping or countervailing duties, or other Section 301 actions unrelated to forced labor. Heading 9903.06.07 addresses only the forced labor component of the Section 301 framework. It does not provide relief from any other duty programs.

If your goods are subject to multiple Chapter 99 headings, each must be reported separately on the entry. Duties from unrelated programs stack on top of the Chapter 1-97 rate independently of this exemption claim. For a broader look at how duty components combine, duty-variance analysis is a useful framework for entry auditing.

Also review entry-level fee calculations, including the Merchandise Processing Fee and Harbor Maintenance Fee, which are unaffected by this exemption heading. Common errors in those calculations are covered in Harbor Maintenance Fee and Merchandise Processing Fee: Common Entry Errors.

If you are uncertain whether 9903.06.07 is the correct Chapter 99 heading for your product or whether another exemption heading in the 9903.05 or 9903.06 series might apply, confirm against the current HTSUS or request a binding ruling from CBP.

What importers should do

• Read subdivision (j)(7)(i) of U.S. Note 52 to Subchapter III of Chapter 99 in the live HTSUS to confirm your product is within scope before claiming 9903.06.07.
• Verify that your goods are the product of El Salvador under CBP's applicable origin rules, and retain supporting documentation for at least five years.
• Report both the Chapter 1-97 classification line and 9903.06.07 on each qualifying entry line, and audit liquidations to confirm the Section 301 forced labor surcharge was not assessed.
• Monitor CBP.gov and the Federal Register for any amendments to the Section 301 forced labor framework that could alter eligibility or add conditions to U.S. Note 52.
