The U.S. notes it refers to

As the 2026 HTS Revision 22 writes them (official notes); each code opens its page. Whether this heading applies to goods depends on the origin, the date and the product: the calculator says it.

(c)

(i) For the purposes of subheadings 9903.45.21 and 9903.45.22 and heading 9903.45.27, except as otherwise provided herein, the term “crystalline silicon photovoltaic cells” (“CSPV cells”) means crystalline silicon photovoltaic cells of a thickness equal to or greater than 20 micrometers, having a p/n junction (or variant thereof) formed by any means, whether or not the cell (or subassemblies thereof provided for in subheading 8541.42.00 and imported under statistical reporting number 8541.42.0010) has undergone other processing, including, but not limited to, cleaning, etching, coating, and/or addition of materials (including, but not limited to, metallization and conductor patterns) to collect and forward the electricity that is generated by the cell. Such cells include photovoltaic cells that contain crystalline silicon in addition to other photovoltaic materials. This includes, but is not limited to, passivated emitter rear contact cells, heterojunction with intrinsic thin-layer cells, and other so-called hybrid cells. Subheadings 9903.45.21 and 9903.45.22 include goods presented in cell form and which at the time of importation are not presented assembled into circuits, laminates or modules or made up into panels.

(ii) Subheadings 9903.45.21 and 9903.45.22 and heading 9903.45.27 shall not cover-

(1) thin film photovoltaic products produced from amorphous silicon ("a-Si"), cadmium telluride ("CdTe"), or copper indium gallium selenide ("CIGS");

(2) CSPV cells, not exceeding 10,000 mm 2 in surface area, that are permanently integrated into a consumer good whose primary function is other than power generation and that consumes the electricity generated by the integrated CSPV cell. Where more than one CSPV cell is permanently integrated into a consumer good, the surface area for purposes of this exclusion shall be the total combined surface area of all CSPV cells that are integrated into the consumer good; and

(3) CSPV cells, whether or not partially or fully assembled into other products, if such CSPV cells were manufactured in the United States.

(iii) Headings 9903.45.25 and 9903.45.27 shall not cover the following goods, whether or not separate statistical reporting numbers therefor may appear in chapters 1 through 97 of the tariff schedule: [(17)] [Provision deleted.]
