A baseline standard on forced labour
ILO Forced Labour Convention No. 29 is one of the core reference points for forced-labour analysis. It defines forced or compulsory labour broadly, while also identifying specific categories that are not treated as forced labour under the Convention when strict conditions are met.
For policy review, the value of the Convention is that it provides a common language. Governments and regulators can disagree about facts in a particular case, but the Convention gives them a shared standard for asking whether labour is exacted under menace of penalty and whether a person has offered themselves voluntarily.
The prison-labour exception is narrow
The Convention includes an exception for work or service exacted from a person as a consequence of a conviction in a court of law. That exception is not open-ended. The work must be carried out under the supervision and control of a public authority, and the person must not be hired to or placed at the disposal of private individuals, companies, or associations outside the Convention's safeguards.
This distinction is central. A prison setting alone does not answer the forced-labour question. Reviewers need to examine the legal basis for the work, who controls it, whether private commercial benefit is involved, and what practical consequences follow if a person refuses.
Why this matters for trade policy
Modern forced-labour rules increasingly operate through trade and market-access measures. If those rules use ILO standards as a reference, they should apply the prison-labour exception carefully and consistently. A narrow exception should not become a broad exemption for any work performed by incarcerated people.
For supply-chain governance, the relevant questions are concrete: public supervision, coercive pressure, compensation, discipline, private-sector links, and traceability. These questions should be asked across jurisdictions rather than only in politically salient cases.
