Key Takeaways
- What they are: Additional duties imposed on imports sold below fair market value (“dumped”)
- Purpose: Protect UK industry from unfair foreign competition and predatory pricing
- Duration: Typically 5 years, subject to review and possible extension
- Check requirement: Always verify current measures before importing affected goods
- Cost impact: Can add 10-100%+ to standard import duty rates
- Who decides: UK Trade Remedies Authority (TRA) investigates and recommends measures
- Key obligation: Declare correct product codes and origin to avoid non-compliance
Anti-dumping duties represent one of the UK’s most significant trade defence tools, capable of dramatically increasing import costs for affected goods. If you’re importing steel, chemicals, textiles, or numerous other products, understanding whether your goods face anti-dumping measures isn’t optional—it’s essential for accurate costing and compliance.
Missing an anti-dumping duty can result in substantial post-clearance demands from HMRC, while incorrectly applying duties wastes money and complicates cash flow planning.
What Are Anti-Dumping Duties?
Anti-dumping duties are additional import charges imposed when foreign producers sell goods in the UK at prices below their “normal value”—essentially below what they charge in their home market or below their cost of production plus reasonable profit.
The Economic Logic
Dumping can occur for several reasons:
- Market penetration: Companies price aggressively to gain market share
- Excess capacity: Producers sell surplus production at marginal cost
- Government subsidies: State support enables below-cost pricing
- Predatory pricing: Deliberate strategy to eliminate competitors
Legal Framework
The UK’s anti-dumping system operates under WTO rules and UK domestic legislation:
- Investigating body: UK Trade Remedies Authority (TRA)
- Decision maker: Secretary of State for International Trade
- Legal standard: Material injury to UK industry must be demonstrated
- Maximum duration: 5 years (with possible 5-year extension)
How Dumping Is Determined
Anti-dumping investigations involve complex economic analysis comparing export prices with “normal value”:
Normal Value Calculation
Method 1 - Home Market Sales: Price charged for identical/similar goods in the exporter’s domestic market Method 2 - Third Country Sales: Price charged in other export markets Method 3 - Constructed Value: Cost of production + selling expenses + reasonable profit margin
Export Price
Usually the first arm’s length sale price in the UK, adjusted for:
- Transport and insurance costs
- Import duties and fees
- Post-importation costs (handling, profit margins)
Dumping Margin
Formula: (Normal Value - Export Price) ÷ Export Price × 100 Example: If normal value is £100 and export price is £80:
- Dumping margin = (£100 - £80) ÷ £80 × 100 = 25%
Current UK Anti-Dumping Measures
The UK maintains dozens of anti-dumping measures inherited from the EU and new measures imposed since Brexit. Key sectors include:

Important: Measures change regularly. Always check the current TRA public register before importing.
How to Check If Your Goods Are Affected
Step 1: Identify Your Exact CN Code
Anti-dumping measures apply to specific 8-digit commodity codes. Use the UK Integrated Tariff to determine your precise classification.
Example: “Steel products” is too broad. You need the specific code like:
- 7208.51.91 (Hot-rolled steel, thickness >10mm, width ≥600mm)
- 7208.52.10 (Hot-rolled steel, thickness 4.75-10mm, width ≥600mm)
Step 2: Check the TRA Public Register
Visit the UK Trade Remedies Authority website and search their measures database by:
- CN code
- Country of origin
- Product description
- Case reference number
Step 3: Verify Current Status
Check that measures are:
- Currently in force (not expired or suspended)
- Applicable to your origin country
- Covering your specific product variation
Step 4: Confirm Duty Rates
Anti-dumping duties can be:
- Ad valorem: Percentage of customs value (e.g., 25.2%)
- Specific: Fixed amount per unit (e.g., £0.15 per kg)
- Variable: Minimum import price system
Practical Compliance Steps
For Import Declaration
- Declare correct CN code: Use precise 8-digit classification
- State accurate origin: Country where goods were produced, not shipped from
- Include anti-dumping duty: Add to standard customs duty calculation
- Provide supporting documents: Invoices, certificates of origin, shipping docs
Documentation Requirements
- Commercial invoice: Must show true transaction value
- Certificate of origin: Proves country of production
- Transport documents: Confirm shipping route and origin
- Form C1207: May be required for certain high-risk goods
Record Keeping
Maintain comprehensive records including:
- Purchase orders and contracts
- Production and shipping documentation
- Correspondence with suppliers about origin
- Any exemption certificates or undertakings
Company-Specific Duties vs General Measures
General Country-Wide Duties
Applied to all imports from specific countries, regardless of producer. Example: Chinese solar panels face 27.3% anti-dumping duty
Company-Specific Duties
Individual rates assigned to specific producers based on their cooperation in investigations. Example:
- Company A (China): 15.2%
- Company B (China): 42.1%
- All others (China): 67.3%
Residual Duty
“All Others” rate: Applied to non-cooperating companies or new producers Usually the highest rate, creating strong incentive for producer cooperation
Exemptions and Special Situations
Undertakings
Some producers accept price undertakings instead of duties:
- Minimum price commitments: Agree to sell above specified price levels
- Volume limitations: Accept quotas on export quantities
- Monitoring requirements: Submit regular sales and pricing data
Processing Relief
Inward Processing Relief (IPR): May suspend anti-dumping duties for goods imported for further processing and re-export
End-Use Relief
Limited exemptions for specific end-uses where no UK production exists
New Exporter Reviews
New producers can request individual duty rates through expedited reviews
Integration with Other Duty Types
Anti-dumping duties operate alongside standard import charges:
Combined Duty Calculation
Total duty = Standard Customs Duty + Anti-Dumping Duty + Import VAT
Example: Chinese steel imports
- Standard duty: 0% (under UK Global Tariff)
- Anti-dumping duty: 25.2%
- Import VAT: 20% on (customs value + duties)
- Total effective rate: ~50%+ including VAT
Interaction with Trade Agreements
- Anti-dumping duties apply regardless of preferential trade agreements
- Rules of origin requirements don’t override anti-dumping measures
- Circumvention rules prevent duty avoidance through third countries
Customs Valuation Impact
Anti-dumping duties don’t affect customs valuation but are calculated on the declared customs value
Common Compliance Mistakes
Mistake 1: Relying on Supplier Classifications
Problem: Accepting supplier’s CN code without verification Solution: Independently verify classification using UK Integrated Tariff
Mistake 2: Ignoring Origin Rules
Problem: Confusing country of export with country of origin Solution: Understand anti-dumping origin rules (often different from preferential origin)
Mistake 3: Assuming Exemption
Problem: Thinking measures don’t apply to specific product variants Solution: Check exact CN code coverage in official measure texts
Mistake 4: Missing Measure Updates
Problem: Using outdated duty rates or expired measures Solution: Check TRA register immediately before each shipment
Mistake 5: Incorrect Declaration
Problem: Under-declaring values to reduce duty burden Solution: Declare true transaction value; penalties exceed any potential savings
Post-Clearance Compliance Risks
HMRC Verification Powers
- Document requests: Can demand supplier invoices, contracts, production records
- Physical verification: Inspect goods to confirm classification and origin
- Post-clearance audits: Review historical imports for compliance patterns
Penalties for Non-Compliance
- Duty recovery: Full amount owed plus interest

Frequently Asked Questions
Q: How often do anti-dumping measures change? A: Regularly. New measures can be imposed within months, while existing measures face review every 5 years. Always check current status before importing.
Q: Can I claim refunds if measures are later revoked? A: Generally no. Duties paid on goods cleared before revocation typically cannot be recovered, though specific legal advice may identify exceptions.
Q: Do anti-dumping duties apply to goods in transit when measures are imposed? A: Usually no. Measures typically apply to goods not yet cleared for free circulation when the measure takes effect.
Q: Can I use my supplier’s anti-dumping exemption certificate? A: Only if you’re importing directly from that specific producer. Exemptions don’t transfer between different suppliers or trading companies.
Q: What if I disagree with HMRC’s classification of my goods? A: Request a Binding Tariff Information (BTI) ruling for official classification. This provides certainty and can be used to challenge incorrect duty demands.
Q: Do anti-dumping duties apply to samples? A: Yes, unless samples qualify for duty relief under specific customs procedures. Commercial value determines liability, not intended use.
