9903.96.02: Civil Aircraft Exemption for Japan Explained

Key Points

• 9903.96.02 is an exemption (claim) heading in the Civil Aircraft Exemption program, and it carries 0 percent additional duty itself.
• It covers civil aircraft (unmanned aircraft excluded), their engines, parts and components, and ground flight simulators and their parts, all of Japan.
• The effective date in the facts is September 16, 2025, with no announced end date for the product and country scope rules shown.
• Eligibility depends on the goods being classified in the subheadings enumerated in subdivision (b) of U.S. note 35 to the subchapter.
• The heading is claimed alongside the regular chapter 1-97 line on the entry, so classification accuracy is the main compliance task.

9903.96.02 is the Chapter 99 heading an importer claims for civil aircraft, their engines, parts, components and flight simulators of Japan, and it carries 0 percent additional duty. It matters to importers, brokers and aerospace supply chains bringing Japanese-origin aircraft articles into the United States. As of October 2026, the facts show it effective September 16, 2025, under the aerospace provisions of the US-Japan Agreement.

The links in this article go to the primary documents: the proclamations, Federal Register notices, and official tariff schedule pages themselves. Read the source. The official text lives in the Harmonized Tariff Schedule at hts.usitc.gov, where you can search for 9903.96.02 and U.S. note 35 directly.

What 9903.96.02 is and what it does

9903.96.02 sits in the Civil Aircraft Exemption program. It is not a tariff action that adds duty. It is an exemption heading: a place on the entry where you declare that the goods qualify for the aerospace treatment negotiated under the US-Japan Agreement aerospace provisions, implemented September 16, 2025.

Official heading text

Articles of civil aircraft (all aircraft other than military aircraft), excluding unmanned aircraft; their engines, parts, and components; their other parts, components, and subassemblies; and ground flight simulators and their parts and components, of Japan, classified in the subheadings enumerated in subdivision (b) of U.S. note 35 to this subchapter

Three limits are built into that text:

• Civil only. Military aircraft are outside the heading.
• No unmanned aircraft. Unmanned aircraft are expressly excluded. For a separate unmanned-aircraft heading in a different program, see 9903.08.20: Section 232 UAS Not-For-UAS Carve-Out Heading.
• Japan and enumerated subheadings. The goods must be of Japan and classified in a subheading listed in subdivision (b) of U.S. note 35.

Which actions it exempts

The facts available for this article state the rate as 0 percent additional duty and identify the heading as an exemption within its program. They do not name the specific additional-duty actions the exemption applies against. Confirm that in the current HTSUS, in U.S. note 35 and the related Chapter 99 headings, or with your broker, before relying on it for a particular entry.

Affected products and HTS coverage

The scope is defined by subheadings, not by a general description. The heading text points to the list in subdivision (b) of U.S. note 35. The scope data we reviewed was capped at 500 records, and the heading may carry more, so no total count is stated here. The first 40 subheadings shown, each with Japan (JP) in scope from September 16, 2025 onward and no announced end date, are:

• Engines and engine-related: 84111140, 84112140, 84148020, 84137020, 84199010
• Machinery and handling: 84251100, 84212300, 84213901, 84158201
• Bearings, gears and drive items: 84833040, 84835090, 84836040, 84839080
• Electrical and electronic: 85013181, 85013320, 85044085, 84715001, 85181040, 85299005, 85299021, 85299055, 85299095
• Instruments and optics: 90019050, 90019060, 90149020, 90309084, 90328100, 91040025, 91040040
• Fittings, tubes and materials: 83022000, 83026030, 73045910, 73049070, 74130090, 81089060, 68138900, 39269045
• Lighting and other aircraft items: 94051140, 94059940, 88079090

Do not treat this as the full list. A subheading missing here may still be enumerated in note 35, and one shown here is only covered when the specific goods are civil aircraft articles of Japan as the heading text describes. Check each line against the live HTS entry. For broader context on 2026 codes, see our 2026 tariff code overview.

Rate and dates

• Rate: 0 percent additional duty.
• Effective window: September 16, 2025 onward, with no announced end date in the scope rules shown.
• Authority: the aerospace provisions of the US-Japan Agreement, as published in the USITC print of 9903.96.02.

The heading text itself carries no date. The only window stated here is the one above. If you are entering goods near a program change, confirm the current status of the heading in the HTSUS rather than assuming it is unchanged.

How it appears on an entry and interacts with other duties

A Chapter 99 heading does not replace your normal classification. The regular chapter 1-97 line, such as one of the subheadings above, stays on the entry, and 9903.96.02 is reported alongside it as the claim. Because 9903.96.02 adds no duty of its own, the point of reporting it is to claim the exemption treatment for qualifying Japanese goods.

Two practical consequences follow:

• The base line still determines your ordinary duty treatment. Confirm that rate in the current HTSUS; this article does not state it.
• If the goods are not of Japan, not civil, unmanned, or not in an enumerated subheading, the heading does not apply and other Chapter 99 treatment may.

If a claim was missed or made wrongly on an entry already filed, see Post Summary Correction (PSC): 300-Day and 15-Day Windows and Customs Recovery: 4 Ways to Get Overpaid Duty Back and Deadlines. The deadlines there apply to your specific entries, so check them early.

What importers should do

• Pull subdivision (b) of U.S. note 35 from the HTS and match each part number and its 8-digit or longer classification against the enumerated subheadings.
• Document country of origin as Japan and confirm each item is a civil aircraft article, not a military or unmanned one, before reporting 9903.96.02.
• Have your broker report 9903.96.02 on the entry line together with the chapter 1-97 subheading, and review CBP guidance for current filing instructions.
• Audit recent Japan-origin aerospace entries for missed claims and raise any corrections with your broker.
