9903.05.30 Chile Section 301 Forced Labor: 12.5% Duty

Key Points

• HTS 9903.05.30 imposes a 12.5 percent additional ad valorem duty on all products of Chile under the Section 301 Forced Labor program, effective July 24, 2026.
• The duty applies to goods of Chilean origin spanning all chapters 1 through 97 of the HTSUS, with no announced end date as of September 2, 2026.
• Legal authority flows from the USTR Section 301 Forced Labor final action dated July 23, 2026, U.S. note 52, and CBP CSMS message 69326983.
• This code is part of the country-specific forced-labor block running from 9903.05.20 through 9903.05.84, which is entirely separate from the Section 301 Brazil block at 9903.05.01 through 9903.05.09.
• The 12.5 percent charge stacks on top of any regular chapter 1-97 duty, Section 232 duties, antidumping and countervailing duties, and other applicable Chapter 99 overlays, so total duty liability can be significantly higher than 12.5 percent alone.

HTS 9903.05.30 is the Chapter 99 tariff code that adds a 12.5 percent ad valorem duty to all products of Chile under the U.S. Section 301 Forced Labor action. The rate took effect on July 24, 2026, and applies to every chapter 1-97 commodity of Chilean origin with no announced end date. Any importer whose goods originate in Chile must report this code on every affected entry made on or after July 24, 2026.

What HTS 9903.05.30 is and who needs to act

Importers of record, customs brokers, and trade-compliance teams handling Chilean-origin merchandise need to be aware of this code immediately. "Products of Chile" means goods whose country of origin, determined under CBP's standard origin rules, is Chile. If your supplier is located in Chile, that alone does not establish Chilean origin; confirm with a thorough origin analysis. If origin is Chile, 9903.05.30 applies.

The code sits inside the Section 301 Forced Labor country-specific block. As of September 2, 2026, that block spans heading codes 9903.05.20 (Algeria) through 9903.05.84, each heading dedicated to a separate country. Do not confuse this block with the Section 301 Brazil block at 9903.05.01 through 9903.05.09, which is a different program with different legal underpinnings.

The Section 301 Forced Labor program and legal authority

The Section 301 Forced Labor program uses the authority of Section 301 of the Trade Act of 1974 to impose additional duties on goods from countries found to engage in unreasonable or discriminatory trade practices related to forced labor. The USTR issued its final action on July 23, 2026. The resulting duty is codified in the HTSUS under U.S. note 52, which governs the entire 9903.05.20-through-9903.05.84 heading block. CBP operationalized the duty in CSMS message 69326983.

Because 9903.05.30 is grounded in U.S. note 52(a), confirm that note's current text in the live HTSUS on the USITC website before making entry decisions, as notes can be amended by subsequent actions. For background on how USTR Section 301 exclusion and conforming-amendment mechanics work in ACE, see our article on USTR Section 301 Exclusion Amendments and ACE HSU 2621.

Product and country scope

Country of origin

The sole country covered by 9903.05.30 is Chile (ISO country code CL). The duty applies to entries of Chilean-origin goods made on or after July 24, 2026. There is no announced end date as of September 2, 2026.

Product coverage

Coverage is sweeping: all products classifiable in chapters 1 through 97 of the HTSUS are within scope when they originate in Chile. There are no product-specific carve-outs or exclusion categories enumerated in the facts available as of September 2, 2026. If you believe a specific commodity may be exempt, confirm that in the current HTSUS or with a licensed customs broker, because the facts block does not identify any exclusions.

The breadth of coverage contrasts with many traditional Section 301 actions that target specific HTS subheadings. Here, every chapter 1-97 line is potentially affected, making origin determination the single most important compliance filter.

The 12.5 percent rate and its effective window

The additional duty rate under 9903.05.30 is 12.5 percent ad valorem. This rate became effective on July 24, 2026, following the USTR final action dated July 23, 2026. There is no announced end date or sunset provision as of September 2, 2026, so the rate should be treated as open-ended until a subsequent USTR or Presidential action modifies it.

The 12.5 percent rate for Chile matches the rate applied to several other country headings in the same block, including Algeria (9903.05.20), Bahamas (9903.05.24), Bahrain (9903.05.25), and Australia (9903.05.23). Other countries in the same block carry a 10 percent rate, such as Canada (9903.05.29), Cambodia (9903.05.28), and Bangladesh (9903.05.26). Rates are country-specific and are not interchangeable across headings.

How the duty stacks with other tariff provisions

The 12.5 percent is an additional duty. It layers on top of, and does not replace, the regular column 1 (MFN) rate applicable to the chapter 1-97 classification. Chile has a free trade agreement with the United States, so many Chilean goods already benefit from a 0 percent MFN or FTA preferential rate. Even so, the 9903.05.30 additional duty is owed on top of whatever preferential rate applies.

If the goods are also subject to Section 232 duties (for example, steel or aluminum derivatives), antidumping or countervailing duty orders, or other Chapter 99 overlays, those charges accumulate further. The facts block does not specify any MFN cap for Chile at 9903.05.30, but rates on other country headings within this block can be MFN-capped; confirm whether any cap applies to Chilean goods in the current HTSUS text. Total landed duty cost on some Chilean products could therefore be materially higher than 12.5 percent alone.

For importers managing sourcing-shift scenarios, note that moving production out of Chile to a non-covered country solely to avoid this duty can raise its own compliance questions. See our article on AD/CVD Circumvention: Legal Sourcing Shifts vs. Evasion for the general framework, which also applies to Section 301 origin-shifting risks.

How 9903.05.30 appears on a customs entry

Chapter 99 codes like 9903.05.30 are reported as a second line on the CBP Form 7501 (or its ACE electronic equivalent) alongside the regular chapter 1-97 classification. The standard sequence is:

• Line 1: The chapter 1-97 HTS subheading describing the actual commodity, with its normal duty rate.
• Line 2: 9903.05.30, reported with the same entered value, producing the additional 12.5 percent charge.

Brokers should verify the correct ACE reporting flags in CSMS message 69326983. Errors in Chapter 99 reporting are a common audit finding and can trigger CBP demands for unpaid duties, interest, and penalties. Use our duty calculator to model total duty liability before entry.

What importers should do

• Audit open and upcoming shipments of Chilean-origin goods. For any entry with a date of importation on or after July 24, 2026, verify that 9903.05.30 was or will be reported and that the 12.5 percent additional duty is included in your duty estimate and actual payment.
• Confirm country of origin determinations. Because 9903.05.30 covers all chapter 1-97 products of Chile, a defensible, documented origin analysis is your primary compliance shield. Retain supplier certifications, bills of materials, and any ruling letters.
• Check for stacking with other duties and any MFN cap. Calculate total duty liability for each commodity using the actual chapter 1-97 rate, any applicable FTA preference, any Section 232 or AD/CVD charges, and the 12.5 percent additional duty. Confirm in the current HTSUS whether a MFN cap limits the 9903.05.30 charge for your specific product.
• Monitor USTR and CBP for amendments or exclusions. The forced-labor action has no announced end date, but USTR may issue exclusions, modifications, or new final actions. Subscribe to CBP CSMS updates and check the Federal Register for any follow-on notices affecting this heading.
