Tell customers about a tariff surcharge, plainly.

How the surcharge is worked out

A duty is charged on the customs value of what is imported, so a duty increase raises the cost of the imported content of a product, not its whole price. The surcharge is the increase in the duty rate, in percentage points, times the imported content's share of the selling price: a duty that rises from 0% to 25% on content that makes up 40% of the price supports a surcharge of 10% of the price.

Charged per unit instead, it is the increase times the customs value of the imported content in one unit: 25 points on $0.124 of imported value is $0.031 a piece.

What the letter says

The product, its HTS code and where it ships from; the duty before and after, with the legal basis if you give one; the surcharge and the date it starts; how it was worked out, if you choose; and, if you choose, that it comes down with the duty within the days you set. It prints as a plain business letter or copies as text for an email, and the surcharge can go onto a quote in the Quote Builder as its own line.

For a code, the page offers the rate the tariff schedule prints for the origin, the Chapter 99 provisions the line's notes point to, and the effective rate on U.S. imports of the line from Census records, each with a button. The rates in a notice should be the ones on your own entries.
