Tariffs have triggered a major supply chain reset, with companies diversifying sourcing and rethinking their entire logistics networks, according to a new survey by STG published via PR Newswire.

The findings point to a shift that goes beyond incremental adjustments. Shippers are not simply absorbing duties at the margin. They are restructuring where they buy, where they route freight and how they configure distribution — the kind of network redesign the industry has not seen at this scale since the immediate post-pandemic recomposition of trade flows.

What is driving the reset?

Tariff exposure sits at the centre of the decision matrix. Faced with higher landed costs on established sourcing lanes, companies are moving procurement away from concentrated country-of-origin footprints and toward diversified supplier bases. The survey frames this not as a tactical hedge but as a structural reallocation of sourcing.

The commercial consequences ripple across every participant in the chain:

• Shippers face upfront costs of qualifying new suppliers and rebuilding lane-level volume commitments, trading near-term margin for tariff resilience.
• Carriers must absorb demand that no longer moves along familiar trade-lane patterns, forcing capacity redeployment toward emerging origin markets.
• Forwarders get an opening to win business on new routings, since shippers redesigning networks typically re-tender their logistics contracts at the same time.

Why network redesign, not just rate shopping?

The survey's core signal is that companies are treating logistics networks as variables, not constants. Rather than negotiating around the edges of existing flows, respondents are rethinking gateway choices, transit structures and distribution footprints in response to the new tariff environment.

That distinction matters commercially. When a shipper changes country of origin, every downstream decision — port pair, mode mix, transshipment hub, inland routing — reopens. Contracts that were stable become contestable. Volumes that anchored specific trade lanes migrate, and carriers that built capacity around the old pattern carry the adjustment risk.

Sourcing diversification compounds this effect. A broader supplier base fragments order sizes, multiplies origin points and complicates consolidation — work that lands disproportionately on forwarders and 3PLs positioned to orchestrate multi-origin freight.

Who gains and who carries the risk?

The reset cuts both ways. Suppliers in destination markets outside the tariff perimeter stand to capture volume previously locked into tariffed lanes. Logistics providers with flexible networks and multi-origin capabilities gain share as shippers rebuild their supply chains around them.

The risk sits with operators anchored to the old geography — carriers whose deployed capacity assumed the pre-tariff flow of goods, and forwarders whose value proposition depended on lanes that shippers are now abandoning.

For shippers themselves, the survey implies a cost curve with a steep front end: supplier qualification, dual-sourcing overhead and the expense of standing up parallel logistics arrangements, all incurred before the tariff savings materialise.

What comes next?

The STG survey indicates the restructuring is already under way rather than hypothetical, meaning trade-lane volumes and carrier capacity decisions over the coming quarters will reflect the new sourcing map — and any further tariff policy shifts will determine how fast, and how far, the reset extends.
