Tariff Updates and Supplier Price Increases

PRICE CHANGES BY EFFECTIVE DATE

Most of these increases apply to outstanding quotations. Several suppliers set order and ship cutoffs to hold current pricing, and those dates are noted below. If you have live quotes or expected orders on any of these lines, read the entry.

August 2, 2026 (in effect)

Eaton - Electrical Americas and GEIS

• Average increase of 4% to 12%, depending on product category.
• Eaton attributes the adjustment to sustained increases in raw material, transportation, and operating costs. Impact varies widely by line, so treat the range as a guide rather than a rule.
• Affected lines include Distribution & Control, Wiring Devices, Crouse-Hinds Series, B-Line Series, Bussmann Series, Power Systems, Critical Power Solutions, and Distributed-IT.

June 14, 2026 (in effect)

Rockwell Automation - Subset of the Rockwell portfolio

• A previously announced adjustment covering part of the Rockwell line, driven by a mix of tariff related costs and continued increases in raw material and component costs. Rockwell has said pricing remains open to further adjustment if U.S. tariff policy changes, so treat quotes on affected products as time sensitive.

June 8, 2026 (in effect)

Marley Engineered Products (MEP)

• Average adjustment of approximately 3.5%, varying by product line.
• Baseboard, cabinet unit heaters, and heat trace are not affected.

June 1, 2026 (in effect)

Arlington - Full line

• Standard increase of 4%, with some products higher or lower.
• The increase applies to outstanding quotations and includes corrections to several past pricing errors.
• Cutoff passed: Arlington accepted orders for immediate release at prior pricing through close of business May 29, 2026.

nVent

CADDY, ERICO, GARDNER BENDER, LENTON, FTZ, ILSCO, UTILCO

• Average adjustment of 0% to 10%, by product class and SKU.
• Adjustments differ significantly across the brand portfolio. Some classes see no change at all, so check pricing at the SKU level rather than assuming a blanket increase.

LEDVANCE - Varies by product type

• Increases differ by product type, and certain high volume product families may be excluded.
• Cutoff passed: Prior pricing was honored on purchase orders accepted by May 15, 2026 and shipped by May 31, 2026. Anything received or shipped after those dates carries the new pricing.

Chatham Brass - Select product lines

• Updated pricing on selected lines. No percentage was published. Chatham Brass has offered to review specific items on request, so send questions on individual part numbers through your account representative.

August 19, 2026 (upcoming): A 50% duty lands on a defined list of Canadian goods

Under Section 338 of the Tariff Act of 1930, an additional 50% duty is scheduled to apply to specific Canadian products. It stacks on top of duties already owed, and qualifying under USMCA does not exempt covered goods.

Energy, potash, critical minerals, and products already covered by Section 232 duties, including steel, aluminum, and copper, are excluded. The published annexes reach well past the headline categories of vehicles, alcohol, and dairy, so confirm classifications on anything you source from Canada rather than assuming your products are outside the scope.

July 24, 2026 (in effect): New Section 301 duties on goods from 60 trading partners

Additional duties of 10% or 12.5% now apply to imports from 60 countries and economies, based on how each one handles prohibitions on goods made with forced labor. Countries with prohibitions in place fall at 10%, the rest at 12.5%.

Goods already covered by Section 232, including steel, aluminum, and automobiles, are exempt, as are a long list of raw materials, supply chain critical items, and certain food, fertilizer, and energy products. These duties took effect the same morning the temporary 10% global duty expired, so for many imports the immediate cost change is modest.

July 20, 2026: Three proclamations set the Canadian duty

The August 19 action was signed on this date and covers roughly $20 billion in annual imports from Canada. Reports since have indicated that U.S. and Canadian leadership agreed to accelerate talks in an effort to reach an agreement before the duty takes effect.

February 2026 (background): Why the legal authorities keep changing

The Supreme Court found that the emergency powers statute used for the earlier round of tariffs did not authorize them. A temporary global duty filled the gap until it expired in late July. The result is a policy that keeps moving between legal authorities, which is why suppliers are writing increases that stay open to further adjustment.

WHAT IT MEANS FOR ELECTRICAL

The full picture across our markets and vendor community is still forming. These are the effects worth planning around.

Higher landed cost. Components and finished goods coming from covered countries carry more duty, and that cost works its way into list prices and multipliers over the following quarters.

Less predictable supply. As manufacturers qualify alternate sources and shift production to countries outside the scope, lead times and availability get harder to forecast.

Broader price pressure. Retaliatory measures and general cost inflation add pressure beyond the directly tariffed items, including on domestically produced goods.
