Rates are quoted as printed. Each 8-digit number opens its own page with footnotes and cited chapter 99 headings.

No line in this heading cites a chapter 99 heading in its footnotes or rate columns.

What this page leaves to your broker

This page quotes the schedule. It does not add the rates together, and it does not say whether a chapter 99 heading applies to a shipment: that turns on the country of origin, the dates and the U.S. notes to chapter 99. Section 301, Section 232 and other chapter 99 measures list the goods they cover in those notes and in Federal Register notices, so a line can be covered by a heading its footnotes never cite. A licensed customs broker makes the determination.
