Executive summaryHMRC’s £4.7m victory against Morrisons signals a more aggressive approach to non-preferential origin enforcement. The ruling shows that supplier declarations are not enough. For importers, origin is a financial, compliance, and governance risk – especially in sectors exposed to anti-dumping duties and trade defence measures. |
Key insights
|
Trade origin has become a frontline enforcement issue. Liability sits with the importer – supplier assurances, certificates, and third-country processing do not transfer responsibility away from the business placing goods into the UK market.
This means that procurement, legal, finance, governance, and supply-chain teams all sit inside the risk perimeter when origin assessments are challenged.
A September 2025 First-tier Tribunal ruling against Morrisons gives HMRC precedent in challenging non-preferential origin declarations, with the retailer left liable for approximately £4.7m in anti-dumping duties and import VAT.
The case centres on imports of aluminium foil declared as Thai origin. HMRC successfully argued that the foil was Chinese in origin, despite processing activity taking place in Thailand.
For importers, the wider implication is this: origin declarations are no longer treated as routine customs administration. They are closely scrutinised as part of a broader enforcement environment shaped by anti-dumping policy, trade defence measures, and supply-chain rerouting.
Why this mattersNon-preferential origin is a major enforcement priority as governments tighten anti-dumping, sanctions, and industrial policy controls. Importers relying on lightly processed goods routed through third countries face financial and compliance exposure – origin risk sits firmly within wider commercial governance. |
HMRC challenged whether Thailand processing was commercially substantive…
The Tribunal concluded that activity taking place in Thailand (including heating, cutting, and packaging) did not substantially transform the product into a new good.
That processing represents only ~5% of total manufacturing cost.
This matters because non-preferential origin is not determined by where final handling occurs, but by whether processing is sufficiently economically justified and results in substantial transformation.
In practical terms, the ruling signals that lightly modified or repackaged goods routed through third countries will face greater scrutiny going forward; particularly where anti-dumping exposure exists.
… and used the supplier’s own website as evidence
HMRC relied partly on statements published on the Thai manufacturer’s website, which reportedly described the facility as having been established to “eliminate anti-dumping duties.” That language proved damaging. The Tribunal agreed it undermined the argument that the processing activity was economically justified in its own right.
For importers, this is an important shift in enforcement posture. HMRC no longer considers shipping documents and supplier certificates as gospel. Public-facing materials, marketing language, corporate structures, investment rationale, and wider commercial context all now feed into origin assessments.
Supply-chain restructuring is colliding with trade enforcement
Over recent years, many firms have diversified production away from China into Southeast Asia and other jurisdictions in response to tariffs, geopolitics, and supply-chain risk. That trend is unlikely to reverse.
However, the Morrisons ruling suggests authorities are increasingly testing whether these restructurings represent genuine manufacturing transformation, or simply tariff circumvention through rerouting and minimal processing.
This is especially relevant in sectors with complex goods already exposed to trade defence scrutiny, including:
- Metals and industrial products
- Aerospace and defence components
- Solar and clean-tech supply chains
- Automotive components
- Electronics and semiconductors
- Chemicals and engineered materials
As anti-dumping regimes expand and CBAM-related enforcement develops, origin risk will only become more commercially significant.
Supplier assurances alone are no longer enough
The clearest outcome of the ruling is that liability remains with the importer.
The Tribunal makes clear that relying on supplier statements at face value does not remove responsibility for validating origin claims. That raises the bar operationally. Importers need deeper visibility into:
- Manufacturing processes
- Cost contribution by jurisdiction
- Component sourcing
- Production sequencing
- Commercial rationale for processing activity
For many, this pushes origin out of the customs team and into wider governance, procurement, legal, and supply-chain risk management.
The bigger picture
The Morrisons ruling is not just about aluminium tin foil. It reflects a bigger shift in how governments enforce trade policy in a fragmented global economy. As tariffs, anti-dumping measures, sanctions, and industrial policy become more politically charged and commercially significant, customs authorities are under pressure to test origin declarations more aggressively.
This means that, for corporate leadership, non-preferential origin cannot be treated as a simple logistics checkbox. It is now a material commercial risk.
