9903.06.10: Argentina Section 301 Forced Labor Exemption

Key Points

• HTS 9903.06.10 is a claim heading, not a duty: it signals that qualifying Argentine goods are exempt from the Section 301 forced-labor additional duty, rather than imposing any new charge.
• The heading applies to articles the product of Argentina, as specifically enumerated in subdivision (j)(8)(i) of U.S. Note 52 to Subchapter III of Chapter 99.
• The rate listed in the HTSUS general column is "the duty provided in the applicable subheading," meaning the underlying Chapter 1-97 duty still applies; only the Section 301 forced-labor surcharge is removed.
• This heading must be reported alongside the regular Chapter 1-97 classification on the entry, not as a standalone line.
• Confirm the current product scope in subdivision (j)(8)(i) of U.S. Note 52, or with your broker, before filing; the facts block for this article is current as of September 26, 2026.

HTS 9903.06.10 is a Section 301 forced labor exemption heading that removes the Section 301 forced-labor additional duty for certain articles originating in Argentina, as defined by subdivision (j)(8)(i) of U.S. Note 52 to Subchapter III of Chapter 99 of the HTSUS. It carries no duty of its own. Importers of qualifying Argentine goods claim this heading on entry to avoid paying the Section 301 forced-labor surcharge, while still paying any otherwise-applicable Chapter 1-97 duties. As of September 26, 2026, the rate stated in the HTSUS general column for this heading is "the duty provided in the applicable subheading."

What 9903.06.10 is and what program created it

Section 301 of the Trade Act of 1974 authorizes additional tariffs on goods from countries found to engage in unfair trade practices. Within that framework, a separate set of Chapter 99 headings addresses goods produced with forced labor. Rather than imposing a duty, headings in the 9903.05.85 onward block and the 9903.06 series function as exemptions or exceptions: they identify specific goods or countries carved out from the forced-labor additional duty.

9903.06.10 is one of those exemption headings. Its official text reads: "Articles the product of Argentina, as provided for in subdivision (j)(8)(i) of U.S. note 52 to this subchapter." The legal authority and the precise product list both live in U.S. Note 52. Importers should read that note in full in the current Harmonized Tariff Schedule at hts.usitc.gov before filing.

Related exemption headings cover goods from other countries. For example, similar exemption logic applies to 9903.06.07 for El Salvador and to the Guatemala block covered under 9903.06.06, 9903.06.05, and 9903.06.04, as well as 9903.06.03 for Cambodia.

Scope of the exemption: products and country of origin

Country of origin

The heading is restricted to articles that are the product of Argentina. Country-of-origin rules for purposes of the Chapter 99 heading follow general CBP substantial-transformation principles unless a specific rule is stated in U.S. Note 52. Confirm the applicable origin rule with your broker or via a CBP ruling letter if your goods involve processing in multiple countries.

Product scope

The eligible products are those "provided for in subdivision (j)(8)(i) of U.S. note 52." The facts block for this article does not reproduce the full product list from that subdivision, and the article cannot add or infer items beyond what U.S. Note 52 states. Check the current HTSUS directly at hts.usitc.gov to confirm whether your specific Chapter 1-97 subheading is enumerated in subdivision (j)(8)(i). If you are uncertain, verify with your customs broker or a binding CBP ruling.

How the rate works: what you pay and what you don't

The HTSUS general column rate for 9903.06.10 is: "The duty provided in the applicable subheading." This language means:

• The heading itself adds zero additional duty. It is purely an exemption claim.
• The importer still owes whatever duties are imposed by the underlying Chapter 1-97 classification, including the normal Most Favored Nation (MFN) rate, any applicable antidumping or countervailing duties, and any other Chapter 99 surcharges that are not the Section 301 forced-labor duty specifically removed by this heading.
• The net effect is that the Section 301 forced-labor additional duty is not assessed on qualifying entries that properly claim 9903.06.10.

How 9903.06.10 appears on a customs entry

Chapter 99 exemption and special-duty headings are reported as a second line on a CBP entry, alongside the base Chapter 1-97 classification. The Chapter 1-97 subheading drives the MFN rate and the tariff description; the Chapter 99 heading (9903.06.10) signals the exemption claim. Both lines must appear on the same entry line or as associated lines per CBP entry instructions.

Importers and brokers should confirm the current ACE reporting requirements with CBP, including any CSMS messages that address how the 9903.06 block is keyed into the Automated Commercial Environment. Check the CBP CSMS page for active guidance messages on this program.

Interaction with other tariff provisions

Claiming 9903.06.10 removes the Section 301 forced-labor additional duty. It does not affect:

• MFN (Column 1 general) duties under the Chapter 1-97 subheading, which remain fully payable.
• Antidumping or countervailing duty orders, which are assessed separately and are unaffected by this heading.
• Other Section 301 duties tied to different programs or different Chapter 99 headings; confirm whether your goods are subject to additional Section 301 tranches not related to the forced-labor program.
• Tariff-rate quota requirements that may apply to the underlying Chapter 1-97 subheading. See our overview of recent TRQ openings for context on quota-subject goods.

If your goods from Argentina are classified under a subheading that carries multiple Chapter 99 overlays, work through the stacking order carefully. The 2026 tariff code overview is a useful starting reference for understanding how Chapter 99 codes interact.

For goods that may fall under more than one classification heading, the GRI 3 essential-character rules govern which Chapter 1-97 subheading controls, before any Chapter 99 overlay is applied.

What importers should do

• Verify product scope in U.S. Note 52, subdivision (j)(8)(i). Pull the current HTSUS from hts.usitc.gov and confirm your specific goods are listed. Do not assume eligibility based on country of origin alone.
• Confirm your Chapter 1-97 subheading is correctly classified before adding the Chapter 99 overlay. An incorrect base classification undermines the exemption claim and may trigger a CBP CF-28 or CF-29 inquiry.
• Report both lines on the entry correctly in ACE. Check current CBP CSMS guidance at cbp.gov for the exact field-by-field requirements for the 9903.06 exemption block.
• Review your full duty stack. Confirm that MFN duties, any antidumping or countervailing orders, and any other applicable Chapter 99 charges are still accounted for after the forced-labor surcharge is removed.
