9903.88.51 - Articles the product of China, as provided for in U.S. note 20(ddd) to this subchapter, each covered by an exclusion granted by the U.S. Trade Representative

This HTS classification, 9903.88.51, specifically covers articles that are products of China and are subject to a temporary modification of duty rates. The defining characteristic for classification under this code is the existence of an individual exclusion granted by the U.S. Trade Representative (USTR). This exclusion is crucial; without it, the goods would likely fall under different provisions related to China origin.

Unlike its sibling categories within Chapter 99, which might represent other temporary legislative measures or trade agreement modifications, 9903.88.51 is exceptionally precise. It targets a subset of goods from China that have received a specific, case-by-case relief from otherwise applicable tariffs or restrictions. Therefore, the presence of a USTR-issued exclusion under U.S. note 20(ddd) to this subchapter is the sole determinant for classification here, distinguishing it from general temporary tariffs or broader import restrictions.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 9903.88.51 is definitive once the criteria of being a product of China and possessing an active USTR exclusion under the specified note are met. Importers must ensure they have documentation substantiating the granted exclusion when declaring goods under this classification.
