U.S. noteExcerptHeadings that refer to it
U.S. note 20(f)(f) Heading 9903.88.03 applies to all products of China that are classified in the following 8-digit subheadings, except products of China granted an exclusion by the U.S. Trade Representative and provided for in (1) heading 9903.88.13 and…9903.88.03, 9903.88.09

Being listed is not owing a duty. A note may list goods that a measure leaves out; whether a heading applies depends on the origin, the date and the product; and the measures on all the goods of a country list no code at all. The calculator says what applies.
