Ethical Sourcing: Choosing and Auditing Suppliers Responsibly

ethical sourcing

Ethical sourcing is the practice of choosing suppliers, and checking how they treat workers and the environment, before and after an order is placed. For a fashion business it turns a values statement into supplier selection, contracts, audits and follow-up.

The wider framework is covered in the guide to ethical business in fashion; this page focuses on the supplier side.

What ethical sourcing covers

Sourcing decisions reach far beyond the invoice. A brand buys from a final garment factory, but that factory relies on fabric mills, dye houses, trimming makers and often home-based or subcontracted workshops. Responsible sourcing asks what happens at every tier a buyer can reasonably find out about, not only at the supplier that ships the goods.

The baseline most programmes use is the set of core labour rights in the ILO Declaration on Fundamental Principles and Rights at Work. It lists freedom of association and the effective recognition of the right to collective bargaining, the elimination of all forms of forced or compulsory labour, the effective abolition of child labour, the elimination of discrimination in respect of employment and occupation, and a safe and healthy working environment. A supplier code of conduct typically restates these as minimum conditions, then adds environmental expectations such as chemical management, wastewater handling and energy use.

Detailed worker-facing topics are explained in the article on garment worker rights, including wages, safety and the right to organise.

Mapping the supply chain before choosing suppliers

Responsible selection starts with knowing who is in the chain. Buyers usually begin with a supplier list covering finished-goods factories, then work backwards to fabric, yarn and raw material producers. Each entry records the site name, address, what it makes, the products it handles for the buyer and whether it uses subcontractors. Gaps are common at the upstream end, where fibre and wet-processing sites are less visible.

Once the map exists, risk is assessed rather than assumed. Typical questions include which countries and processes carry higher risk, which products depend on a single site, and where the buyer has little influence because orders are small. The EU framework describes this as focusing effort: under the Commission’s page on corporate sustainability due diligence, companies may focus on areas where impacts are most likely and most severe, based on reasonably available information. Small brands can borrow the same logic: prioritise the highest-risk suppliers instead of attempting a perfect view of everything at once.

Selecting suppliers: what to ask and what to look for

Selection combines documents, conversations and, where possible, a visit. A sensible pre-qualification covers the following areas.

  • Legal and ownership details: registration, licences and any parent company or related factories.
  • Policies and records: written policies on hours, wages, discrimination, grievance handling and safety, with evidence that they are applied.
  • Existing certificates and audit reports: what was assessed, by whom, when, and whether findings were closed.
  • Subcontracting practice: whether work is passed to other sites and how the supplier controls that.
  • Capacity and lead times: whether the supplier can meet the order without relying on excessive overtime.

The last item matters more than it looks. Fair Wear describes its approach as aligning brands, suppliers, workers and civil society, and lists equitable sourcing, meaning responsible contracting and purchasing practices, enabling suppliers to improve working conditions, including living wages. In other words, ethical sourcing includes the buyer’s own purchasing practices, not only the factory’s.

Audits, certifications and their limits

An audit is a structured check of a site against a standard or code. Audits can be done by the buyer, by an independent body or by a multi-stakeholder initiative. They are useful for establishing facts about a site on a given day, but they are not a guarantee, because issues such as forced labour, harassment or hidden subcontracting are hard to detect in a short visit when workers cannot speak freely.

Certification works differently from a buyer audit. Under GOTS, for example, to sell a product as certified, each company involved in the processing must be certified by an approved independent Certification Body, which creates a consistent, traceable system from fibre processing to finished product. Such schemes verify a defined standard for defined products and stages. They do not replace a buyer’s own judgement about a supplier’s overall conduct, and they say little about sites outside their scope.

Repetition is another problem. When many buyers send separate auditors to the same factory, the site spends time on visits rather than improvement. Fair Wear has published an item on how it and SLCP are working together to drive data convergence and reduce audit fatigue, which reflects an industry-wide push to share assessment data instead of duplicating it.

From findings to corrective action

An audit finding has value only if it leads to change. The usual cycle is to record each non-compliance, agree a corrective action plan with a named owner and a deadline, verify closure, and review again. Serious issues, such as evidence of child labour or forced labour, call for immediate remediation that protects the people affected, not simply ending the order.

Responsible exit is part of the same logic. Dropping a supplier at the first problem can leave workers worse off than before, so many programmes prefer staged engagement and treat termination as a last resort once improvement has clearly failed. Fair Wear lists access to remedy, meaning enabling workers to safely raise concerns and access effective remedy, among the elements of its due diligence work, which points to grievance channels as a practical tool: workers need a safe route to report problems that does not run only through factory management.

Worker voice is the other safeguard. The same Fair Wear page describes actively involving stakeholders, and particularly workers, in decision-making that affects factory working conditions. Interviews held away from managers, worker committees and trade union engagement give a view that paperwork alone cannot.

How regulation shapes sourcing practice

Voluntary codes are increasingly backed by law, although the main EU rule does not apply yet. At the time of writing, the EU due diligence directive, as amended by the Omnibus I package, sets a corporate due diligence duty for the very large companies that fall within its scope: EU companies with at least 5,000 employees and EUR 1.5 billion net turnover worldwide, and non-EU companies with at least EUR 1.5 billion net turnover in the EU. Those companies will have to identify and address actual and potential adverse human rights and environmental impacts in their own operations, those of their subsidiaries and in their chains of activities, supported by complaints and notification procedures, monitoring and public communication. Under the amended text, Member States must adopt national measures by 26 July 2028 and apply them from 26 July 2029; the amending Directive (EU) 2026/470 explains that the application deadline for all companies should be postponed to that date.

The Commission’s page also states that micro companies and SMEs are not covered, although the directive provides supporting and protective measures for smaller business partners that may be indirectly affected, including limits on information requests, guidance and model contractual clauses. In practice this means a small supplier may still receive questionnaires from a larger customer that is in scope. Clear, proportionate requests help: ask only for information that is actually needed and share the purpose. Rules and timetables have been amended more than once, so the current text on the Commission’s page is the reference, and this article is general information rather than legal or compliance advice.

Product-level transparency is a related theme, explained in the article on the EU digital product passport; good supplier records support it.

Practical habits for small fashion businesses

A small brand does not need a large compliance team to source responsibly. Habits that scale down well include:

  • keeping a current list of suppliers and sites, updated whenever a subcontractor changes;
  • using a short supplier code of conduct built on the ILO core rights and asking suppliers to sign and explain it;
  • preferring fewer, longer relationships so suppliers can plan, and paying on agreed terms;
  • asking for existing third-party reports before commissioning a new audit;
  • keeping a record of decisions, findings and follow-up, since this is the evidence behind any public claim.

That last habit links sourcing to marketing. Statements such as “ethically made” should match what the records show, and the scope should be stated plainly, for example which products or sites a claim covers.

Frequently asked questions

Is a certificate enough to prove a supplier is ethical?

Not by itself. A certificate shows that a site met a particular standard for a defined scope, but buyers still need to check what the scheme covers, who carried out the assessment and how findings were followed up.

Do small brands have to follow due diligence law?

The Commission states that micro companies and SMEs are not directly covered by the directive, yet they can be affected indirectly if a larger customer in scope asks for information. Requirements differ by country and change over time, so official sources should be consulted.

What should happen when an audit finds a serious problem?

The priority is to protect affected workers and fix the cause. A corrective plan with deadlines and checks follows, and ending the relationship is generally a last resort after improvement has failed.

Why do unannounced visits and worker interviews matter?

Announced visits can show a site at its best. Confidential conversations with workers reveal conditions that records may not, which is why worker voice features in due diligence programmes.
