Short answer: 9903.94.52 is a Chapter 99 heading under the Section 232 autos and auto-parts program (U.S. note 33). It matters to importers of European Union-origin parts for passenger vehicles and light trucks whose column 1 duty rate is 15 percent or more. As of November 2026, the heading itself adds no duty: the rate is "the duty provided in the applicable subheading."
What 9903.94.52 is
9903.94.52 sits in the Section 232 autos and auto-parts group of headings governed by U.S. note 33 to the subchapter. It is a claim-type heading, not a duty-imposing one. Filing it tells CBP that the part is an EU product within the scope of subdivision (o) of U.S. note 33 and that the rate condition in the heading text is met.
It is one of the country-deal variants. These variants are tied to the base headings 9903.94.01 and 9903.94.05, which they modify. If you want the full set of headings in the note, check the official Harmonized Tariff Schedule.
Coverage and the 15 percent condition
The official heading text
Parts of passenger vehicles and light trucks that are products of the European Union as specified in subdivision (o) of U.S. note 33 to this subchapter, with an ad valorem (or ad valorem equivalent as provided for in subdivision (m) of U.S. note 33 to this subchapter) rate of duty under column 1 equal to or greater than 15 percent.
Reading the conditions
- Product type: parts of passenger vehicles and light trucks.
- Country condition: the part must be a product of the European Union, as specified in subdivision (o) of U.S. note 33.
- Rate condition: the column 1 rate of duty must be ad valorem, or an ad valorem equivalent as provided in subdivision (m) of U.S. note 33, and equal to or greater than 15 percent.
The rate condition looks at the regular column 1 rate on the chapter 1-97 line, not at any Section 232 rate. If your part's column 1 rate falls below 15 percent, this heading does not match on its face. Check the heading list in the HTSUS for the variant that fits.
The facts available here do not list which HTS subheadings fall under the heading, so do not assume a part is covered because it is an EU-origin automotive component. Match your tariff line to the note and the heading text. For a related EU parts heading, see 9903.94.44: Section 232 EU Auto Parts Heading Explained.
Rate and dates
The general column rate for 9903.94.52 is "the duty provided in the applicable subheading." In practical terms, the heading adds no duty of its own. The duty you owe on the entry line comes from the regular chapter 1-97 subheading, plus whatever other provisions apply to the goods.
The facts available for this article carry no effective window, no entry date, and no deal rate for this heading. This article therefore states none. Before you rely on the heading, confirm in the current HTSUS and in U.S. note 33 the date from which it applies and what treatment it produces. If you are unsure, ask your broker to check it against the current schedule.
Interaction with other tariff provisions
Base headings and sibling variants
The country-deal variants modify the base headings 9903.94.01 and 9903.94.05. A claim under 9903.94.52 should be read as a variant of those headings, not as a stand-alone program. For comparison with other headings in the same note, see:
- 9903.94.04: Section 232 passenger vehicle heading
- 9903.94.02: Section 232 autos heading, no added duty
How it appears on an entry
Like other Chapter 99 headings, 9903.94.52 is reported on its own line alongside the regular chapter 1-97 line for the same part. The chapter 1-97 line carries the ordinary classification and column 1 rate. Accurate origin reporting also matters here, since the heading turns on EU origin. See our guide to the MID code on ACE entry lines.
Other duties
The facts available do not address how this heading stacks with other duties such as Section 301 or other Section 232 measures. Confirm stacking treatment in the current HTSUS and the relevant notes. Our 2026 tariff code overview lists related codes.
What importers should do
- Check each part's chapter 1-97 line: confirm the column 1 rate is ad valorem (or an ad valorem equivalent under subdivision (m) of U.S. note 33) and is 15 percent or more before using 9903.94.52.
- Confirm EU origin against subdivision (o) of U.S. note 33, and document it in your entry records.
- Read 9903.94.01, 9903.94.05, and the current note 33 text on hts.usitc.gov to confirm the dates and treatment that apply to your entry date.
- Review CBP's guidance on the CBP website and notices at federalregister.gov for current filing instructions.
