What is HTS 9903.88.15?

HTS 9903.88.15 is a Chapter 99 heading in the Harmonized Tariff Schedule of the United States (HTSUS) that imposes additional duties on specific imports from China under Section 301 of the Trade Act of 1974. It targets products listed in U.S. Note 20(s) to subchapter III of Chapter 99, covering approximately $120 billion in annual Chinese imports known as Tranche 4A.

The full description reads: 'Except as provided in headings 9903.88.39, 9903.88.42, 9903.88.44, 9903.88.47, 9903.88.49, 9903.88.51, 9903.88.53, 9903.88.55, 9903.88.57, 9903.88.65, 9903.88.66, 9903.88.67, 9903.88.68, or 9903.88.69...' These exceptions point to product-specific modifications or exclusions where the additional duty may be zero or adjusted.

Unlike earlier tranches that hit strategic sectors like semiconductors, Tranche 4A focuses on everyday consumer goods. We’ve seen importers from agriculture to apparel grappling with this code daily. The duty is 7.5% ad valorem on the CIF value, added to the base Most Favored Nation (MFN) duty of the primary HTS subheading. For instance, a $200 shipment of Chinese toys might incur an extra $15 under this code alone.

History and Rate Changes

Implemented on September 1, 2019, via Federal Register notice 84 FR 43304, the initial rate was 15%. It was halved to 7.5% on February 14, 2020 (85 FR 8581), following the Phase One trade agreement. As of the latest HTSUS release in February 2026 and USTR guidance, this rate persists without further reduction.

Recent developments include stacking with new 2025 IEEPA tariffs (e.g., 9903.01.24 at 20%), amplifying costs. We advise clients to factor these into total landed cost calculations meticulously.

This timeline underscores the need for ongoing monitoring, which we facilitate through our tools.
