Alternative sourcing origins also face tariff exposure
The forced-labor-related Section 301 action took effect on 24 July, setting duties of 10% or 12.5% for covered goods from 60 economies, subject to product exemptions and country-specific treatment. For importers shifting purchases away from China, a new origin may still carry exposure under this action. These goods duties are separate from the maritime Section 301 measures.
Freight is only one part of that sourcing calculation. Duty treatment can outweigh a lower ocean quote, while a new origin may require feeder transport or offer fewer direct departures. The relevant comparison is the landed cost and delivery plan for the product.
The tariff heading and applicable exemptions determine the duty on an individual entry. The policy creates a reason to reassess sourcing; it does not, by itself, explain every summer volume shift.
