How a tariff wrote ten forced labor laws in fifteen weeks
Evidencity updates its February 2026 Taxonomy of Transparency report with a closer look at Forced Labor in Developing Nations research.
In February 2026, our taxonomy of global modern slavery law identified a blank map. The taxonomy found no supply chain transparency or due diligence legislation in Latin America beyond Brazil, in sub-Saharan Africa, in the Middle East and North Africa, or across most of Asia. It named the gap specifically: India, Bangladesh, Vietnam, Thailand, Indonesia, and the Philippines.
Evidencity's own report called them "countries at the centre of global supply chains where forced labour is most prevalent." Each still lacked an equivalent domestic framework. Our conclusion was blunt. "The blank map was not going to be filled by legislation from producing countries any time soon," we wrote at the time.
Five of those six countries have since passed exactly this kind of law.
A US tariff threat did this. A decade of advocacy hadn't. The Office of the US Trade Representative (USTR) published Section 301 findings against 60 trading-partner economies on 5 June 2026, citing their failure to ban forced-labor imports. USTR then set two tariff tiers under Ambassador Jamieson Greer. Economies with a ban already in place, or a binding commitment to adopt one, paid 10%. Everyone else paid 12.5%. Across a 15-week stretch from mid-April to late July, 10 governments enacted import bans of their own. Five moved before USTR's June findings; five moved after, racing the deadline. India and Sri Lanka legislated inside the seven-week comment window and dropped a full tariff tier. Vietnam missed the deadline by one day and stayed at the higher rate, a lapse worth 2.5 points of tariff.
Most compliance programs are missing this: nine of those 10 new laws share the same architecture. All nine put the obligation on a customs or trade agency. That agency screens imports at the border and blocks what it flags. The importer's own supply chain carries no separate duty under any of them. That's the enforcement model the US runs at its own border. The European Union took a decade to legislate its Corporate Sustainability Due Diligence Directive, which puts the obligation on companies themselves. Legislative trackers built around the European Union, the United Kingdom, and Canada are trained to watch for that company-side model, and miss the border-screening model these new laws actually use.
Cambodia is one of the starkest cases. Cambodian ministries drafted the ban in documented consultation with USTR's own Section 301 Committee, and Commerce Minister Cham Nimul tied its timing to the tariff publicly. As of August 2026, no Reuters, AP, BBC, AFP, or Financial Times story has named it.
A supply chain running through Guatemala, Cambodia, Sri Lanka, or the Dominican Republic is now operating under an enforcement regime that didn't exist five months ago, with no case law, no audit history, and in most cases no coverage in the outlets a compliance team is trained to monitor.
Standard screening tools only capture yesterday's risks. That's why network-level intelligence matters more than entity-level screening. A name-check tells you whether someone is on a list. It doesn't tell you a government wrote an import law in direct coordination with the agency about to tax it, and that no one covered it at all.
We track the laws before the wires do, because ground-truth research starts in the jurisdiction itself.
