Effective May 1, 2026, new Section 232 tariff provisions took effect for certain products imported from Taiwan. The changes were published through updates to the Harmonized Tariff Schedule of the United States (HTSUS) and later communicated by U.S. Customs and Border Protection through CSMS guidance.
The new provisions affect several product categories, including qualifying automotive parts, self-certifying automotive parts, certain wood products, and qualifying civil aircraft components. While the changes are highly technical, the practical impact is that some Taiwan-origin products may see reduced Section 232 tariff exposure, while others remain subject to specific additional duties.
Changes for Certain Taiwan Automotive Parts
One of the most significant changes involves qualifying passenger vehicle and light truck parts from Taiwan.
Under the new provisions, certain automotive parts classified under HTSUS Chapter 99 headings 9903.94.66 through 9903.94.69 may qualify for modified Section 232 treatment. For some products, if the existing HTS duty rate is already 15% or greater, no additional Section 232 duty applies. For other qualifying products with an existing duty rate below 15%, Section 232 duties apply only until the combined duty burden reaches 15%.
These provisions apply only to products that meet the specific requirements outlined in the HTSUS notes and CBP guidance. Importers should carefully review product classifications and supporting documentation before assuming eligibility.
Self-Certifying Automotive Parts
Additional provisions apply to certain self-certifying automotive parts used in U.S. vehicle production or repair activities.
These products may qualify for modified tariff treatment when the importer of record certifies that the parts meet the applicable requirements. However, various exclusions remain in place, including certain products classified within Chapters 72, 73, and 76, along with other exclusions identified within the HTSUS notes.
Because these provisions involve specific certification requirements, importers should maintain adequate documentation supporting eligibility.
Taiwan Wood Products
The updated provisions also establish a new tariff treatment for certain covered Taiwan wood products.
Products covered under the applicable HTSUS provisions are subject to a 15% additional ad valorem duty under Chapter 99 heading 9903.76.24. Importers should note that this treatment does not eliminate other applicable duties that may apply. Antidumping duties, countervailing duties, and other fees may still be assessed depending on the product and classification.
Proper classification remains critical to determining the total duty obligation.
Civil Aircraft Components
Another significant change affects qualifying Taiwan-origin civil aircraft components.
Products meeting the applicable eligibility requirements may qualify for treatment under HTSUS heading 9903.96.03. Under the updated rules, these qualifying products are exempt from additional Section 232 aluminum, steel, and copper derivative duties.
Importers should continue reporting applicable Special Program Indicators when required and ensure that all eligibility criteria are met before claiming the exemption.
Refund Opportunities and Compliance Considerations
Importers may also have opportunities to recover duties paid on eligible entries.
CBP guidance indicates that certain qualifying entries made between May 1 and May 28, 2026 may be eligible for refunds through the Post Summary Correction process. Businesses should review affected entries promptly to determine whether corrections or refund opportunities may exist.
Companies utilizing Foreign Trade Zones should also be aware of additional requirements. Certain Taiwan automotive parts admitted into a U.S. Foreign Trade Zone on or after May 1, 2026 must be admitted in “privileged foreign status,” a specific designation under Foreign Trade Zone regulations.
Final Thoughts
The Taiwan Section 232 tariff changes introduce several new provisions that may affect duty calculations, compliance requirements, and refund opportunities for importers.
While some products may benefit from reduced Section 232 exposure, eligibility depends on specific classifications, product descriptions, certifications, and entry requirements. Importers should carefully review the applicable HTSUS provisions, CBP guidance, and supporting documentation to ensure proper compliance.
As always, understanding how tariff changes affect your specific products is an important part of managing risk, controlling landed costs, and maintaining a compliant import program.
