Why prison labour matters for supply-chain policy
Global supply-chain governance often focuses on production in lower-income countries. That focus can be important, but it is incomplete if it overlooks labour-risk categories within high-income economies. US prison labour is one such category.
Civil-society reporting and investigative journalism have described incarcerated people working for very low pay, under disciplinary pressure, and in systems that can connect to public or commercial supply chains. These conditions raise questions that should be assessed through the same evidence-based framework used in other forced-labour contexts.
The blind spot is not only legal, but comparative
ILO Convention No. 29 does not treat every form of prison labour as forced labour. It recognises a narrow exception, but that exception is tied to safeguards such as conviction by a court, public supervision and control, and limits on private-sector disposal of prisoners.
When trade rules focus closely on some jurisdictions while giving limited attention to prison labour in partner economies, the result can be a comparative blind spot. A credible system should ask comparable questions about consent, coercion, wages, discipline, supervision, and commercial benefit.
Questions for enforcement design
Supply-chain due diligence should be able to examine whether incarcerated workers have meaningful choice, whether refusal carries penalties, whether work is linked to private commercial entities, and whether buyers can trace products or services connected to detention or prison systems.
None of these questions predetermines an enforcement outcome. They do establish a baseline for consistent review. If forced-labour rules are intended to protect workers, the scope of inquiry should follow evidence rather than geopolitical convenience.
