HTS 9903.82.25 is a Chapter 99 classification under the Consolidated Metal 232 program. It applies a 15 percent additional duty to equipment parts, as defined under notes (f) and (k), whose non-U.S. metal content falls below the 15 percent threshold. The code has been in effect since June 8, 2026, and is scheduled to terminate on January 1, 2028. Importers of affected equipment parts must report this code alongside their standard Chapter 1-97 classification on every entry filed during the effective window.

What 9903.82.25 covers and which program created it

The Consolidated Metal 232 program reorganized and unified Section 232 steel and aluminum tariff obligations under the 9903.82 block of the Harmonized Tariff Schedule. Within that block, equipment parts receive their own tier structure keyed to U.S.-origin metal content. The facts as of August 28, 2026 confirm the following official heading text for 9903.82.25:

Equipment-parts tier non-US-content (f),(k), col1 <15%: floor 15%

In plain English, this heading targets equipment parts that are subject to notes (f) and (k) of the Consolidated Metal 232 regime and that carry a U.S. metal content percentage below 15. The "floor 15%" language signals that 15 percent is the minimum additional duty assessed at this content tier, regardless of the Column 1 general rate.

Notes (f) and (k): what they mean for scope

The specific scope of notes (f) and (k), including exactly which equipment categories and metals are captured, is defined within the Chapter 99 U.S. notes of the official HTSUS. Confirm the precise note text in the current tariff schedule or with your broker, because the notes establish which equipment parts qualify and how U.S. content is measured.

For a look at how neighboring codes in the same equipment-parts tier work, see our articles on 9903.82.23, which sets a 10 percent floor, and on 9903.82.21, which applies to CA/MX low U.S.-content goods.

The rate, its effective window, and the termination date

The additional duty under 9903.82.25 is 15 percent, effective June 8, 2026. The announced termination date is January 1, 2028. That means entries made on or after June 8, 2026, and before January 1, 2028, must include this classification when the goods meet the note (f) and (k) equipment-parts criteria and the U.S.-content threshold is below 15 percent.

Any entry filed outside that window, including entries with a date of import before June 8, 2026, should not carry 9903.82.25. If you have liquidated entries that incorrectly include or omit this code, confirm the correct protest or post-summary correction posture with your broker. Confirm the current effective status in the HTSUS before filing.

Scope: which goods and countries are affected

The facts block does not identify a country-specific exclusion or inclusion list for 9903.82.25. The heading text does not name specific origin countries, which means the duty applies on a Most Favored Nation basis to qualifying equipment parts from any country unless a specific exemption heading in the 9903.82 block applies to the shipment. Confirm whether a country-specific exemption or a derivative metal exemption heading covers your goods by reviewing the full 9903.82 block in the HTSUS.

The content threshold, below 15 percent U.S. metal content, is the primary sorting mechanism. Equipment parts at or above 15 percent U.S. content would not fall here; they would fall into a different tier heading within the same equipment-parts structure. The exact method for calculating and documenting U.S. content for customs purposes is governed by the Chapter 99 notes. Confirm the calculation methodology with your broker or in the current HTSUS text.

How the duty stacks with other tariff provisions

Chapter 99 codes like 9903.82.25 are additive. The 15 percent additional duty applies on top of the standard Column 1 general rate from Chapters 1 through 97. It also stacks with any other Chapter 99 provisions that apply simultaneously to the same line item, for example, Section 301 duties on goods of Chinese origin.

This means the landed duty calculation for a qualifying equipment part requires adding the Column 1 rate plus 15 percent plus any other applicable Chapter 99 duty. Use a structured duty model or our duty calculator to build out the full stack before making sourcing decisions.

Antidumping and countervailing duties assessed on the same merchandise are separate from Section 232 duties. They are calculated on a different basis and through a different legal mechanism.

How 9903.82.25 appears on a CBP entry

On a CBP entry, 9903.82.25 is reported as a secondary classification line. The underlying Chapter 1-97 HTS code for the merchandise appears first; 9903.82.25 rides alongside it on its own line with a reported value and the applicable duty rate. CBP's Automated Commercial Environment (ACE) system applies specific reporting-order requirements for Chapter 98 and 99 codes. For detail on ACE line-order rules, see our article on CBP updates to ACE HTS reporting order for Chapter 98 and 99 classifications.

The dutiable value for the 9903.82.25 line is typically the same entered value used for the Column 1 duty line. Confirm the correct value basis with your broker, as the Chapter 99 notes may specify adjustments.

What importers should do

• Verify note (f) and (k) applicability. Pull the current Chapter 99 U.S. notes from hts.usitc.gov and confirm your specific equipment parts fall within the defined scope before reporting 9903.82.25 on an entry.
• Document U.S. content below 15 percent. Prepare and retain supplier certifications or cost build-ups showing that the U.S.-origin metal content in the finished part is below 15 percent. This documentation supports the classification and is available for CBP review at any time.
• Model the full duty stack. Add the 15 percent Section 232 duty to your Column 1 rate and any other applicable Chapter 99 duties. Use the duty calculator to run scenario analysis across content tiers, since parts at or above 15 percent U.S. content would attract a different rate under a neighboring heading.
• Monitor the termination date. The announced termination date is January 1, 2028. Track any regulatory updates through the Federal Register and the HTSUS to catch any extension, modification, or early termination before it affects your entries.
