Tariff Watch8541.42.00.10 from Australia resolves to 12.50%: a Column 1 General rate of 0.00% and one trade remedy on top of it. That is one line of many under solar cells and modules. Rates within the category differ, so the figure is what this line draws rather than a rate for the category as a whole.

What is in scope
Section 301 reaches solar cells and modules under Chapter 99 heading group 9903.91 and the provisions of HTS 854142, 854143. The full list of classifications and the instrument behind the action are on the solar cells and modules page.
Australia also faces a country-wide additional duty of 12.5%, reported under 9903.05.23. That reaches goods of Australia whatever they are. The Australia page sets out every action reaching that origin.
Reading this figure
Duty is assessed at the ten-digit statistical line, not at the category and not at the four-digit heading. A different line under solar cells and modules can carry a different Column 1 rate and, where a trade remedy enumerates provisions rather than a whole chapter, a different set of layers. The calculator resolves a specific code, origin and value.
For what each layer above is: Section 232, Section 301, Section 338, how the layers combine.
