The Modern Slavery Act 2015 and merchandise procurement
For UK businesses with a turnover of £36 million or more that supply goods — including merchandise — the Modern Slavery Act 2015 requires an annual slavery and human trafficking statement. Procurement teams need to be ready to evidence the statement's content.
UK and EU framework
The Modern Slavery Act 2015 is the central piece of UK legislation on slavery, servitude, forced or compulsory labour and human trafficking. Section 54 requires commercial organisations that supply goods or services, have a turnover of £36 million or more, and carry on business or part of a business in the UK, to publish an annual slavery and human trafficking statement. The statement must describe the steps the organisation has taken during the financial year to prevent modern slavery in its business and supply chains.
The Act does not currently require smaller businesses to publish a statement, but it does not exempt them from the underlying criminal offences under Sections 1 and 2 of the Act, which carry unlimited fines and the possibility of a director's disqualification order under the Company Directors Disqualification Act 1986. Buyers below the £36 million threshold can still be asked by procurement clients to evidence supply-chain due diligence.
Beyond the Act itself, the UK is a signatory to the ILO conventions on forced labour, the UN Guiding Principles on Business and Human Rights, the OECD Due Diligence Guidance for Responsible Business Conduct, and the UK government's voluntary principles on public-sector procurement. Public-sector procurement rules in England, Wales, Scotland and Northern Ireland all include social-value criteria that touch on modern-slavery risk.
Pricing and framework
Modern-slavery compliance is essentially a procurement and governance overhead rather than a direct line-item on the merch invoice. The cost is borne in supplier onboarding, audit and continuous monitoring, and the prices of certified-goods tend to be 5–18% higher than uncertified equivalents.
UK merch pricing (exclusive of VAT): standard apparel £12–£55 per piece; standard drinkware £7–£28 per piece; standard bags £5–£22 per piece; standard welcome packs £25–£120 per pack. Apparel certified to GOTS organic cotton, GRS recycled-content or OEKO-TEX Standard 100 typically carries a 5–15% premium over the uncertified equivalent. Apparel carrying Sedex Members Ethical Trade Audit (SMETA) or amfori BSCI audited-factory evidence carries an additional premium because the supplier has incurred the audit cost and recovered it through price.
Lead time
Onboarding a new supplier to a level suitable for inclusion in a modern-slavery statement typically takes 6–12 weeks. The timeline covers the supplier's published policies, the supplier's audit history, the risk-assessment scoring, the contractual warranties and the contractual right-to-audit. For first-time buyers this adds materially to the standard 4–6 week production lead time; for buyers with an established supplier roster, the new supplier is onboarded once and the merch programme uses the existing supplier list.
For programmes with significant first-time supplier engagement, plan the new-supplier onboarding to start 6–12 weeks before the merch brief is issued. Where the timeline is tighter, a documented risk-assessment exception can be put in place under the buyer's modern-slavery policy, with appropriate mitigations and elevated review.
Seasonal planning
Modern-slavery reporting has its own calendar. The annual slavery and human trafficking statement is published within six months of the financial year-end for most UK-incorporated businesses. For 31 December year-ends, the statement covers the calendar year and is published by the following 30 June; for 31 March year-ends, it is published by the following 30 September; for 31 December year-ends, it is published by the following 30 June. April–June is the busiest reporting window.
Procurement teams preparing the merchandise for Christmas distribution or for a Q1 event should align the supplier onboarding with the buyer's statement timeline so that the Q4 spend is reflected in the annual statement. Where spend falls into a different reporting period, mid-year supplementary updates may be appropriate for buyer's governance committees.
Delivery and hand-over
The merchandise itself follows the standard UK courier map: Royal Mail, DHL UK, DPD UK, Evri, FedEx UK, UPS for international. Modern-slavery compliance does not change the physical delivery model; it changes the documentary chain that supports the buyer's statement.
The buyer retains records showing which supplier produced each item, the country of origin, the factory site, and the audit status. For goods produced in higher-risk geographies (parts of South and South-East Asia, certain regions in Latin America, parts of Eastern Europe outside the EU) the documentation is held longer and audited more frequently. For goods produced in lower-risk geographies (UK, EU, North America, Australia, New Zealand, Japan), the documentation can be lighter.
What this is and what it includes
This article covers the procurement-side obligations UK businesses face under the Modern Slavery Act 2015 when sourcing corporate merchandise. It is written for procurement leads, sustainability leads, general counsel and ESG reporting teams at UK businesses that buy merchandise and have reporting obligations to meet.
Coverage includes the £36 million threshold, the statement content requirements under Section 54(4), the practical procurement-side due diligence (supplier mapping, supplier audits, contractual warranties), the published policies required (on modern slavery, on ethical sourcing, on whistleblowing), the training requirements, and the relationship with adjacent obligations (the Financial Conduct Authority's rules for FCA-regulated firms, the Procurement Policy Note 09/15 for central government procurement, the NHS supplier-code of practice, and the CMA Green Claims Code for sustainability claims).
It does not cover the underlying criminal offences of slavery and servitude under the Act, which are reserved for prosecution teams. It does not cover international-modern-slavery instruments outside the UK and EU, although the OECD Due Diligence Guidance is referenced at the appropriate point.
When and for whom
This article is written for: procurement directors and category managers at UK businesses that buy corporate merchandise; sustainability leads running the buyer's modern-slavery programme; ESG reporting teams preparing the annual statement; in-house legal teams reviewing supplier contracts; agencies and event partners delivering merch on behalf of clients with reporting obligations; suppliers themselves preparing the audit-ready documentation; and smaller buyers who need to understand what their larger clients will ask for.
It applies to all UK businesses that buy corporate merchandise and meet the Section 54 threshold (turnover of £36 million or more, supplying goods or services, carrying on business in the UK). It applies whether the merch is sold (event merchandise, retail), distributed free of charge (gifts, samples), or used internally (staff merch). It applies across all categories of merchandise — apparel, drinkware, bags, packaging, printed matter, signage, electronics.
It does not apply to buyers below the threshold who are not otherwise required to publish a statement (although they may still want to do so for customer-facing ESG positioning). It does not apply to UK public-sector bodies, which are subject to the Procurement Policy Note 09/15 in their own right and beyond the scope of this article.
Specifications and materials
The act does not specify which materials or products are subject to the disclosure obligation; it captures any commercial supply of goods or services where the buyer meets the threshold. The buyer's risk assessment will, however, prioritise higher-risk product categories.
Apparel and textiles are the highest-priority category because the global apparel supply chain is recognised by the UK government and the ILO as carrying elevated modern-slavery risk. Cotton from Xinjiang, garment production in certain South and South-East Asian factories, and tannery operations in certain regions are highlighted in published guidance.
Drinkware (ceramic, glass, stainless steel) and bags (cotton, polyester, jute, hemp) carry similar risk profiles. Electronics and tech accessories carry a different risk profile (cobalt mining, mineral sourcing from conflict-affected and high-risk areas, sub-contracted assembly). The OECD Due Diligence Guidance for Responsible Mineral Supply Chains applies to tin, tantalum, tungsten and gold; consumer electronics supplied into UK merch programmes typically fall within the scope of this guidance.
Common mistakes
The most common modern-slavery mistake on UK merch is treating the statement as a stand-alone annual publication that is not connected to actual procurement practice. The Act requires the statement to describe the steps actually taken; an aspirational statement that does not reflect the procurement reality fails the Act's requirement.
The second is failing to obtain contractual warranties from merchandise suppliers. The Act does not make warranties mandatory, but the absence of a contractual right-to-audit and an obligation to evidence the supply chain makes it very difficult to write the statement with reasonable confidence. Contractual terms should be in place with all tier-one merchandise suppliers; tier-two and tier-three supplier visibility is desirable but often harder to obtain.
The third is publishing on the wrong page. The Act requires the statement to be on the buyer's website, with a prominent link from the homepage. Statements published only on the investor-relations page, only on the sustainability microsite, or only as a PDF attachment to the annual report do not meet the requirement.
The fourth is failing to keep the statement under board-level review. The Act does not require board approval, but the guidance recommends it and the regulator expects evidence of senior-level engagement. Statements prepared by junior procurement staff without senior sign-off are more vulnerable to challenge.
The fifth is treating small-scale merch as exempt from due diligence. The threshold for the statement is at corporate level, but the procurement-side due diligence applies to all merchandise, regardless of order value. A small-batch merch purchase from a new supplier still requires the standard onboarding process.
Process and steps
The standard procurement-side process for modern-slavery compliance on merch runs as follows. Map the buyer's merchandise suppliers. Score each supplier on country-risk and product-risk indices. Require suppliers to publish a modern-slavery or ethical-sourcing policy. Require suppliers to disclose their factory list and their audit history. Where audits are not available, require site visits or third-party audits (SMETA, BSCI, SA8000). Document the procurement-side due diligence in the buyer's records.
On the contract side, the merchandise purchase order or supply contract should include a modern-slavery warranty from the supplier, a right-to-audit clause, a representation that the supplier has not been the subject of a modern-slavery enforcement action, and an obligation to flow the equivalent standards down to the supplier's own suppliers.
On the reporting side, the buyer maintains records of the supplier onboarding, the audits, the contract warranties, the training delivered to procurement staff, and any incidents or remediation actions taken during the reporting period. This is the input to the buyer's annual statement.
On the assurance side, buyers above the threshold may commission external assurance on the statement from a third-party assurance provider. The assurance standard applied is typically ISAE 3000 or equivalent; buyer's advisers will confirm the appropriate standard for the buyer's reporting context.
Case study
A UK retailer with a turnover above £500 million ran a Christmas gifting programme of 4,500 welcome packs across branded apparel, drinkware and packaging. The buyer's procurement team applied the standard modern-slavery onboarding to all four tier-one merchandise suppliers.
Two suppliers (a UK-based drinkware supplier and an EU-based apparel supplier) were already on the buyer's roster and had current SMETA audits on file. The third supplier was a new entrant for branded bags; the buyer ran the standard onboarding, including the country-and-product risk score, the supplier's policy review, and a remote audit of the supplier's tier-one factory.
The fourth supplier could not evidence modern-slavery compliance within the buyer's required timeline and was excluded from the programme. The buyer documented the exclusion in the buyer-side procurement records and referenced the tier-four supplier in the annual statement's description of the steps taken.
The programme was delivered on time. The buyer's annual statement recorded the four-supplier review, the onboarding of the new bags supplier, the exclusion of the fourth supplier and the resulting supply-chain decisions for the Christmas programme.
Compliance and certifications
Modern-slavery compliance sits within a wider compliance picture for UK merch: VAT (covered separately), UK GDPR and the Data Protection Act (covered separately), product safety (UKCA / CE marking, depending on goods), environmental marketing under the CMA Green Claims Code, sector-specific codes (ABPI for pharma, FCA for financial promotions, ASA for advertising) and public-sector procurement rules.
The supplier-side certifications most commonly seen on UK merch are SMETA (Sedex Members Ethical Trade Audit), amfori BSCI (Business Social Compliance Initiative), SA8000 (Social Accountability International), GOTS (Global Organic Textile Standard) and GRS (Global Recycled Standard). These certifications evidence the supplier-side ethical-sourcing controls; the buyer's statement draws on them as input.
The buyer-side certifications most commonly seen are Achilles (for utilities and infrastructure buyers), the NHS Supplier Information Security Scheme, Cyber Essentials Plus, and ISO 20400 (Sustainable Procurement). These are voluntary but evidence the buyer's broader procurement controls.
Comparison with other solutions
Compared with catalogue-based promotional product distributors, the dedicated UK merch supplier brings a higher degree of supply-chain visibility. Catalogue distributors often aggregate supply from many sources; the supply-chain mapping may not be transparent and the buyer's statement content is harder to evidence.
Compared with overseas-sourced merch from Asian or other higher-risk suppliers, UK-domestic and EU-sourced merch carries lower modern-slavery risk per the published country-risk indices. UK-domestic merch will not eliminate risk (there are UK cases that have been prosecuted), but the documentation and audit chain is typically shorter.
Compared with print-on-demand and drop-ship merch, the supplier is typically smaller and may have less mature modern-slavery compliance. Buyer's onboarding requirements may need to flex to accommodate smaller print-on-demand suppliers; the Modern Slavery Act is approached on a risk-based basis and lower-risk purchases require lower levels of due diligence.
Program lifecycle
A typical UK B2B merch programme under modern-slavery compliance runs from brief to closure in 4–8 weeks. The first 1–2 weeks cover supplier onboarding for any new suppliers (or the delta review for existing suppliers); weeks 2–4 cover production and decoration; weeks 4–6 cover packing, paperwork and freight; weeks 6–8 cover delivery. The annual statement is prepared separately and tracks back to the procurements conducted across the financial year.
Repeat programmes use the existing supplier roster and run on the standard 4–6 week timeline. New-supplier onboarding is conducted once and added to the roster. The annual statement is the governance cycle's anchor point; mid-year updates are conducted when supply-chain incidents or remediation actions warrant.
The programme closes with the supplier's contractual warranty attestation and the buyer's procurement-side records being added to the buyer's modern-slavery evidence trail. The annual statement is then drafted from the evidence trail and published within the Section 54 reporting window.
Closing note
The Modern Slavery Act 2015 requires a published annual statement from UK businesses that supply goods or services and meet the £36 million turnover threshold. The statement must describe actual procurement-side due diligence. Plan the merchandise supplier onboarding as part of the buyer's modern-slavery programme, not as a one-off exercise per merch brief. Document everything; the statement content must be evidence-led.
