New forced-labor tariffs raise duties on power imports

A July 23 White House action imposed new Section 301 forced-labor tariffs on goods from 60 economies, lifting duties on power adapters, chargers and cables starting July 24. The move raises absolute costs for importers but preserves the 25-point China-only tariff gap that still favors non-China sourcing.

Why it matters: - U.S. importers of power adapters, chargers, cables and related hardware now face a higher duty stack that started July 24, 2026. - The new tariff changes the absolute cost of importing from China and Vietnam, but it does not remove the pricing advantage of sourcing outside China. - Procurement teams still have the same core China-plus-one incentive because the China-only tariff layer remains in place.

What happened: - A White House presidential action issued July 23, 2026 imposed new Section 301 “forced-labor” tariffs on goods from 60 economies. - The action set a 12.5% duty on China, Vietnam and 41 other economies. - The action set a 10% duty on 17 additional economies, including Mexico and Canada. - The measure took effect July 24, 2026, replacing a temporary 10% surcharge that expired the same day. - USMCA-compliant goods from Mexico and Canada are exempt. - The measure is being challenged in court.

The details: - For switching power adapters classified under HTS 8504.40.85, the effective duty on Chinese-origin goods rises to 37.5%. - For the same product, the effective duty on Vietnamese-origin goods rises to 12.5%. - Those rates are about 2.5 points higher than under the surcharge that was replaced. - Cable assemblies, coaxial cable and optical fiber carry the same overlay on top of their base rates. - The 25% Section 301 tariff on goods of Chinese origin still applies on top of the new duty. - The new duty also applies to Vietnam, so the gap between China and a non-China source narrows only in absolute dollars, not in the sourcing decision itself. - Kestner Supply said the figures were current as of July 29, 2026 and verified against the U.S. Harmonized Tariff Schedule and the July 23 action. - Kestner Supply maintains a public, verified duty stack for power and connectivity imports at the company’s insights page and a browser-based duty-estimate tool.

Between the lines: - Kestner Supply argues the market overread the expiring surcharge as relief. - The real sourcing signal is the 25-point List 3 Section 301 tariff that applies to Chinese-origin goods only. - The forced-labor basis adds a second layer of risk because origin now affects both tariff cost and documentation quality. - A lower-priced quote only works if the stated origin is real and supported by customs documentation. - Final assembly of Chinese subassemblies does not change Chinese origin for tariff purposes, so re-labeling alone does not solve the problem.

What's next: - Importers are likely to keep re-testing supplier mix, but the basic re-sourcing math built before July 24 still holds. - Buyers considering a second origin will need to confirm substantial transformation, not just assembly, to secure non-China origin treatment. - Customs scrutiny may intensify around entries where origin claims and manufacturing facts do not match.

The bottom line: - The new tariffs raise costs, but they do not erase the economic case for China-plus-one sourcing. The floor moved up; the China-only advantage remained.
