(b) For the purposes of this note, “semiconductor articles” refers to imported products meeting certain technical parameters and that are classifiable in the provisions of the HTSUS enumerated in this subdivision: 8471.50 8471.80 8473.30 To be included within the definition of semiconductor articles, the imported products must be a logic integrated circuit, or an article that contains a logic integrated circuit, that meets the technical parameters of having: (1) a total processing performance greater than 14,000 and less than 17,500, and a total DRAM bandwidth greater than 4,500 GB/s and less than 5,000 GB/s; or (2) a total processing performance greater than 20,800 and less than 21,100, and total DRAM bandwidth greater than 5,800 GB/s and less than 6,200 GB/s. For the purposes of this note, total processing performance (TPP) is 2 × “MacTOPS” × “bit length of the operation,” aggregated over all processing units on the integrated circuit. “MacTOPS” is the theoretical peak number of Tera Harmonized Tariff Schedule of the United States Revision 15 (2026) Annotated for Statistical Reporting Purposes XXII 99 - III - 365
