Tariff type is read from the letter text: "Removed / reduced" when the letter removes, eliminates or lifts a tariff charge (or is a decrease), "Tariff surcharge" for a separate surcharge, otherwise a list-price increase that names tariffs as a reason. Steel & aluminum or copper is shown when the letter names that metal.
Frequently asked questions
What is a tariff surcharge on building products?
A separate charge a manufacturer adds to the invoice to pass on tariff costs, instead of raising its list prices. Of the 91 tariff letters on file, 11 letters add a separate surcharge and 77 letters raise list prices and name tariffs as a reason.
How much are manufacturers raising prices because of tariffs?
Across the 52 US letters that cite tariffs and state a percentage, the median increase is 10% and the middle half fall between 6% and 12.5% (a range like "3-8%" counts at its midpoint). Letters often blame tariffs together with other costs, so not all of an increase is tariff-related.
Which building products are affected by tariffs?
By trade: Plumbing Supply (65), Roofing Material (11), Electrical Supply (5), HVAC Equipment (5), Decking & Railing (1), Door Hardware (1). When a letter names the tariff: steel & aluminum (16), copper (2), not specified (73).
Do tariff surcharges come off when tariffs change?
Sometimes. 3 letters on file remove or cut a tariff charge: GMS (Aug 1, 2026), Emerson (Aug 18, 2025), Crane (May 13, 2025).
Are Canadian prices affected differently?
12 letters on file are for Canadian pricing, tagged "Canada" below. They follow Canada's own tariffs, so check them separately from US letters.
How do you decide a letter is tariff-related?
The word "tariff" appears in its stated change, product description or summary. Letters that only mention general "cost increases" are not included, so the list is a lower bound. The tariff type is read from the same text.
