Traceability supports responsible sourcing
Responsible sourcing asks how purchasing decisions and supplier relationships affect people and the environment. Traceability helps locate those relationships: who supplied an input, where it was produced, which products contain it and what evidence supports that account. A connected record creates a route for investigation; it does not establish that every activity along that route was responsible.
The OECD Due Diligence Guidance for Responsible Business Conduct is an international guidance framework. It should not be presented as a single market-access law or a universal certification. Specific legal duties must be assessed separately.
Connect sourcing concerns to real facilities
Begin with a product family and the materials that matter to the sourcing question. Map the contracting supplier, actual production facilities, outsourced processors and relevant upstream sources. If a trader cannot disclose a processor, record that gap and decide who will resolve it.
A supplier code of conduct describes an expectation. Review evidence about how that expectation operates at the facility and during the relevant period. Keep the source and limitations of findings visible, including restrictions on independent access or worker participation.
Treat labour conditions as a separate evidence layer
Batch and custody records describe a product history. Labour-related evidence concerns the conditions under which work took place. Link the two layers through sites, activities and dates so a reviewer can see whether a finding relates to the product under review.
Protect sensitive worker information and avoid requests that could expose people to retaliation. Assign qualified reviewers to interpret labour-related concerns and agree a safe escalation process. A complete supplier map should not be used as a substitute for understanding impacts or responding to concerns.
Keep market decisions framework-specific
A purchasing team can use the same facility map when considering the EU product prohibition and US import enforcement. Record separate legal assessments, responsible owners and evidence requests for each. Do not create a single green compliance label that hides differences between the frameworks.
Use evidence review states to distinguish what has been reported, reviewed, disputed or left unresolved. An operational status tells colleagues what still needs work; it is not a legal clearance.
Make the sourcing process repeatable
Choose a small set of suppliers and test whether a colleague can reproduce one product-to-source relationship. Check the time needed to retrieve records and resolve an inconsistency. Use the outcome to improve supplier agreements, review ownership and follow-up practices.
Review new processors, changing materials and unresolved concerns as the relationship evolves. Preserve prior assessments and the reason for a changed conclusion. The implementation plan can structure the data pilot; the sourcing programme also needs decisions about prevention, response and accountability.
