Import Duties, Anti-Dumping and Preferential Tariffs Explained
- John Hall
- Customs Specialist at iCustoms.ai
The HS code is the key that unlocks every duty calculation. When goods cross a border, customs authorities use the commodity code of those goods to identify the applicable duty rate, check whether a preferential rate is available under a trade agreement, determine whether anti-dumping or safeguard measures apply, and assess whether the consignment falls within a tariff rate quota. Every one of these outcomes is driven by the HS code. Get the code right and the duty calculation follows. Get it wrong and the financial consequences compound across every shipment.
This guide covers UK import duty rates by product category, how to calculate the full import fee using a landed cost calculator, the mechanics of tariff rate quotas, how preferential tariff rates work under UK free trade agreements, and how anti-dumping duties are triggered at the HS code level. It also covers HS code trade compliance obligations for businesses operating across multiple markets.
UK Import Duty Rates Explained
UK import duty rates are set by HMRC through the UK Global Trade Tariff, which came into effect on 1 January 2021 following the end of the EU transition period. Rates are expressed as a percentage of the customs value of the goods (ad valorem) or as a specific amount per unit of quantity (specific duty), or a combination of both. The applicable rate for any given product is determined by the 10-digit commodity code assigned to that product.
The UK applies Most Favoured Nation (MFN) rates to imports from all countries with which it does not have a preferential trade agreement. MFN is the standard rate and represents the highest duty a WTO member country will charge another WTO member. Where the UK has a free trade agreement or a unilateral preference scheme in place with the origin country, a preferential rate that is lower than MFN may apply, provided the goods meet the relevant rules of origin.
UK MFN rates were largely carried over from EU Common External Tariff (CET) rates at the point of Brexit, but HMRC has since introduced the UK Global Tariff which diverges from the EU CET on a growing number of product categories. UK rates are now an independent schedule that must be checked separately from EU rates.
| HS Chapter | Product Category | UK MFN Rate Range | Notes |
|---|---|---|---|
| Ch. 01–05 | Live Animals, Meat, Fish, Dairy | 0% – 40.5% | Agricultural products generally carry the highest MFN rates. Certain cheese subheadings can attract duties of up to 40.5%. |
| Ch. 09–10 | Coffee, Cereals, Flour | 0% – 19.2% | Roasted coffee is typically duty-free, while some cereal preparations and processed products attract higher rates. |
| Ch. 22 | Beverages: Wine, Spirits, Beer | 0% – 14% | Excise duty is charged separately and is not included within the customs duty percentages shown. |
| Ch. 30 | Pharmaceuticals and Medicines | 0% | Most pharmaceutical products are duty-free under the WTO Pharmaceutical Agreement. |
| Ch. 61–62 | Clothing and Apparel | 12% | One of the highest consistently applied MFN duty rates in the UK tariff schedule, covering many finished garments. |
| Ch. 63 | Made-Up Textiles, Bed Linen | 6% – 12% | Rates vary depending on the specific textile product and classification. |
| Ch. 64 | Footwear | 8% – 17% | Higher rates generally apply to footwear with leather uppers, while sports footwear classifications vary. |
| Ch. 84 | Machinery and Mechanical Equipment | 0% – 3.7% | Most industrial machinery attracts low or zero duty, although certain specialist equipment remains dutiable. |
| Ch. 85 | Electrical Equipment and Electronics | 0% – 14% | Many ICT products are duty-free under the Information Technology Agreement (ITA), while consumer electronics may attract duty. |
| Ch. 87 | Vehicles and Parts | 0% – 6.5% | Passenger vehicles can attract duties up to 6.5%, while qualifying electric vehicles may benefit from preferential treatment under applicable trade agreements. |
| Ch. 90 | Optical, Medical, and Precision Instruments | 0% – 3.7% | Many medical devices and precision instruments are duty-free or subject to very low duty rates. |
| Ch. 94 | Furniture | 0% – 5.7% | Wooden furniture commonly attracts duties around 5.7%, while metal furniture is often subject to lower rates. |
MFN vs Preferential:
The rates in the table above are MFN rates and apply to goods imported from countries without a UK free trade agreement. If goods originate in the EU, Japan, Australia, or another UK FTA partner country and meet the relevant product-specific rules of origin, a preferential rate – often 0% – applies instead. See the Preferential Tariff Rates section below.
Import Duty Rates: UK, EU and US Comparison
For businesses exporting from the UK to third markets, or sourcing goods from countries that trade across multiple jurisdictions, the following table compares MFN duty rates for common product categories across the UK, EU, and US. At the six-digit HS subheading level, the three countries apply different MFN rates reflecting independent national tariff schedules.
| HS Code | Product | UK MFN Rate | EU MFN Rate | US MFN (HTS) Rate | Notes |
|---|---|---|---|---|---|
| 6109.10 | Cotton T-shirts (Knitted) | 12% | 12% | 16.5% | The UK and EU remain aligned on many apparel tariff lines, while the United States applies a higher MFN rate. |
| 6403.99 | Leather Footwear | 8% | 8% | 10% | UK and EU rates are broadly aligned; US footwear tariffs vary depending on construction and materials. |
| 8413.70 | Centrifugal Pumps | 1.7% | 1.7% | 0% | The United States applies a zero MFN rate, while the UK and EU retain a low customs duty. |
| 8517.13 | Smartphones | 0% | 0% | 0% | Zero-rated across all three jurisdictions under the WTO Information Technology Agreement (ITA). |
| 8703.23 | Passenger Cars (1500–3000cc) | 6.5% | 6.5% | 2.5% | The US MFN rate is significantly lower than the equivalent UK and EU rates. |
| 2204.21 | Wine in Bottles Under 2 Litres | 5.6% | 0% | Varies by Origin | EU-origin wine benefits from EU tariff treatment, while imports into the UK may be subject to MFN duties where no preferential arrangement applies. |
| 0406.90 | Cheese (Other) | 39.1% | Up to 40.5% | Varies | Agricultural tariff-rate quotas (TRQs) may provide reduced rates for qualifying import volumes. |
| 8471.30 | Portable Computers (Laptops) | 0% | 0% | 0% | Duty-free in all three jurisdictions under the WTO Information Technology Agreement (ITA). |
Import Fee Calculator: How to Work Out What You Will Pay
The total cost of importing goods into the UK is not simply the customs duty percentage applied to the invoice value. The full landed cost of an import includes the customs duty, import VAT, and potentially a range of additional charges that are each determined by the HS code of the goods. An import fee calculator works through these components systematically to give an accurate total before the goods arrive at the border.
The components that feed into a complete import cost calculation are set out below. Every one of them is indexed to the commodity code.
| Cost Component | How It Is Calculated | HS Code Role | Typical Range |
|---|---|---|---|
| Customs Duty | Ad valorem duty applied to the CIF customs value (cost + insurance + freight) of the imported goods. | The commodity code determines the applicable MFN or preferential duty rate. | 0% – 40.5% (UK); average across all goods approximately 2.8%. |
| Import VAT | Typically 20% applied to the customs value, customs duty, and eligible transport costs to the UK destination. | The HS code determines whether goods qualify for VAT exemptions or reduced/zero-rated treatment. | 0% (exempt or zero-rated goods) or 20% (standard-rated). |
| Anti-Dumping Duty | Additional fixed or percentage-based charge imposed on top of normal customs duty where a trade remedy measure applies. | The HS code at the 8- or 10-digit level triggers anti-dumping checks and determines whether a measure applies. | Varies widely; often 30% – 80%+ for affected products. |
| Tariff Rate Quota (TRQ) Charge | Reduced in-quota rates apply until the quota volume is exhausted, after which the out-of-quota duty rate applies. | The HS code identifies whether the product is covered by a TRQ and which quota applies. | In-quota: often 0%; Out-of-quota: can exceed 100%. |
| Excise Duty | Specific statutory amount charged per litre, kilogram, or unit for regulated products. | The HS code identifies excise-liable goods such as alcohol, tobacco, and energy products. | Fixed statutory rates; not calculated as a percentage of value. |
| UK Customs Examination Fee | Charged when HMRC or a port authority selects goods for physical examination or inspection. | Not directly HS-code-specific, but incorrect classification can increase inspection risk. | Typically GBP 100 – 600+ per examination. |
| Port Handling and Storage | Storage and handling charges incurred while goods remain at the port or terminal. | Not directly linked to the HS code, although classification errors often lead to customs delays and additional storage costs. | Typically GBP 20 – 100+ per day per container. |
iCustoms Tool:
iCustoms’ Landed Cost Calculator takes the commodity code, country of origin, customs value, and shipping cost as inputs and returns the full landed cost including duty, import VAT, and any applicable anti-dumping or TRQ charges. It pulls live rates from the UK Trade Tariff, which means the calculation reflects current duty rates including any in-year tariff amendments published by HMRC.
How to Find the Import Duty Rates for Your Product
Finding the correct import duty rate for a product requires three pieces of information: the commodity code of the product, the country of origin, and the customs value. With those three inputs, the UK Trade Tariff on GOV.UK returns the applicable rate and any measures that modify it. The following steps walk through the process.
| Step | Action | What to Look For |
|---|---|---|
| 1 | Identify the correct 10-digit UK commodity code for your product | Use the UK Trade Tariff search at trade.gov.uk or iCustoms‘ iClassification tool. The commodity code must be accurate because duty rates, trade measures, and customs declarations are all based on this classification. |
| 2 | Go to the UK Trade Tariff and enter the 10-digit code in the Import search | Ensure you are using the Import section. The Export section focuses on export controls and licensing requirements rather than import duty calculations. |
| 3 | Select the correct country of origin from the origin dropdown | Origin determines whether preferential tariff treatment is available. Goods meeting Rules of Origin under a UK Free Trade Agreement may qualify for reduced or zero duty. |
| 4 | Review the Duties and Restrictions section of the commodity code result | Check the MFN rate, preferential rates, anti-dumping measures, tariff rate quotas (TRQs), safeguard measures, and any import licensing requirements. |
| 5 | Check whether a tariff suspension or temporary duty reduction applies | Some products benefit from temporary tariff suspensions where domestic production is limited or unavailable. These measures appear in the tariff Measures section and can significantly reduce duty costs. |
| 6 | Calculate the customs value correctly | The UK generally uses the CIF basis (Cost + Insurance + Freight to the UK port of entry). Add these amounts together before applying the customs duty rate. |
| 7 | Add import VAT | Import VAT is generally calculated on the customs value plus customs duty and certain additional transport costs. Most VAT-registered importers use Postponed VAT Accounting (PVA) instead of paying VAT at the border. Some qualifying goods may be zero-rated or exempt. |
Shortcut:
iCustoms’ iClassification tool combines Steps 1 and 2 into a single search. Enter the product description, and the tool returns the commodity code, current duty rate, preferential rates by origin country, and any active trade measures. It replaces the manual UK Trade Tariff lookup process for businesses managing large product catalogues.
Preferential Tariff Rates: HS Codes and Free Trade Agreements
Preferential tariff rates are reduced duty rates available to goods that originate in a country with which the UK has a free trade agreement or a unilateral preference scheme. HS codes and free trade agreements are directly linked: the HS code of the product determines which product-specific rule of origin (PSR) applies, and the PSR determines whether the goods qualify for the preferential rate. Without satisfying the PSR for the relevant HS heading, no preference claim is valid.
Since Brexit, the UK has negotiated and ratified a growing set of independent free trade agreements that are distinct from the EU’s trade arrangements. UK traders can no longer rely on the EU’s network of FTAs and must check UK-specific preferential rates for each origin country. The most commercially significant UK FTAs for duty purposes are the UK-EU Trade and Cooperation Agreement, the UK-Japan Comprehensive Economic Partnership Agreement (CEPA), the UK-Australia Free Trade Agreement, and the UK Developing Countries Trading Scheme (DCTS) for imports from eligible developing countries.
| Agreement | Partners | Preferential Rate for Qualifying Goods | HS Code Requirement | Key Sectors |
|---|---|---|---|---|
| UK–EU Trade and Cooperation Agreement (TCA) | 27 EU Member States | 0% duty on most goods where Rules of Origin are satisfied | HS headings are referenced in Product-Specific Rule (PSR) tables within TCA Annex 3. Goods must satisfy the applicable rule for their tariff heading. | Manufacturing, agri-food, chemicals, vehicles, and textiles. Rules of origin are particularly stringent for automotive and textile products. |
| UK–Japan Comprehensive Economic Partnership Agreement (CEPA) | Japan | Staged tariff reductions with most goods reaching 0% after transition periods | HS-based PSRs apply. Goods typically need to satisfy tariff shift requirements (CTSH) or value-added thresholds depending on the heading. | Vehicles, electronics, machinery, and agri-food products. |
| UK–Australia Free Trade Agreement (UKAFTA) | Australia | Many goods receive immediate 0% duty; others phase down to 0% over 5–15 years | HS-based PSRs apply, and exporters must retain evidence demonstrating qualifying origin. | Agriculture, wine, beef, manufacturing, and services-related trade. |
| UK–New Zealand Free Trade Agreement | New Zealand | Most tariffs reduce to 0% within seven years | HS-based PSRs apply. Preference claims generally rely on exporter declarations and supporting origin evidence. | Dairy, lamb, agriculture, and manufactured products. |
| UK Developing Countries Trading Scheme (DCTS) | Eligible Developing and Least Developed Countries | Reduced rates or 0% duty on many goods, with enhanced preferences for least-developed countries | A REX Statement on Origin is generally required. The HS heading determines eligibility and the applicable preference rate. | Textiles, clothing, food products, and light manufacturing. Key beneficiaries include Bangladesh, Sri Lanka, and Kenya. |
| UK Global Tariff (MFN – No FTA) | All Other WTO Members | Standard MFN duty rates apply; no preferential treatment available | The HS code remains essential for determining the applicable MFN rate, but no Rules of Origin compliance is required for preference purposes. | Applies to trade with countries where no UK FTA preference is available, including many major trading partners. |
Preferential Tariff Treatment UK-EU: How It Works in Practice
A certificate of origin is a trade document that declares the country in which a product was produced, manufactured, or substantially transformed. Customs authorities use it to determine whether imported goods qualify for a preferential tariff rate under a free trade agreement, a unilateral preference scheme, or an international trade arrangement. Without it, goods are assessed at the Most Favoured Nation (MFN) rate, which is often significantly higher.
What is a certificate of origin for customs? It is the formal declaration of origin submitted alongside the customs entry to claim a reduced or zero duty rate. The certificate does not simply state a country name. It confirms that the goods meet the origin rules set out in the relevant trade agreement or preference scheme, including the product-specific rules (PSR) that are tied directly to the HS code of the product.
The customs certificate of origin therefore operates in direct conjunction with the HS code. The product-specific rule for a given HS heading determines what counts as sufficient working or processing to confer origin. Without the HS code, you cannot identify the applicable PSR. Without the PSR, you cannot confirm whether the goods qualify for the certificate of origin that will reduce the duty rate.
COMP Note:
GOV.UK guidance confirms that goods must meet the product-specific rules of origin applicable to their HS heading under TCA Annex 3 to qualify for preferential tariff treatment. The rules vary by heading. A product that qualifies for preference at the 6-digit HS subheading level may not qualify at the 8 or 10-digit commodity code level if a more specific rule applies. Always verify at the full commodity code level, not the heading level.
What Is a Tariff Rate Quota?
A tariff rate quota (TRQ) is a trade mechanism that allows a specified volume of goods to be imported at a reduced or zero duty rate (the in-quota rate), with any imports above that volume subject to a significantly higher duty rate (the out-of-quota rate). TRQs are used to manage the volume of competing imports in sensitive sectors, typically agriculture, while still meeting WTO market access commitments.
In the UK, TRQs are administered by HMRC and the Department for Business and Trade (DBT). The UK maintained most of the EU’s TRQ commitments at Brexit and has since negotiated new TRQs in its own trade agreements. Each TRQ is identified by a quota order number that appears in the UK Trade Tariff under the Measures section for the affected commodity code. Once the quota volume is exhausted for the relevant quota period, all subsequent imports of that product are charged at the higher out-of-quota rate.
How TRQs Work: The in-quota volume is typically defined in tonnes, kilograms, or units per quota year. Importers can claim a preferential in-quota rate by submitting a licence application or by filing under a first-come-first-served quota directly on the Customs Declaration Service. When the quota is full, the CDS will not accept in-quota claims and the declaration defaults to the out-of-quota rate.
| TRQ Element | Description | Worked Example: Poultry (HS 0207) |
|---|---|---|
| In-Quota Volume | The total quantity of imports allowed to enter at the reduced tariff rate during a defined quota period, typically one year. | The UK maintains tariff rate quotas for certain frozen poultry products, with annual in-quota volumes allocated by country or trading arrangement. |
| In-Quota Rate | The reduced customs duty rate that applies while quota volume remains available. | Qualifying poultry imports may benefit from a 0% duty rate when imported within the available TRQ allocation. |
| Out-of-Quota Rate | The standard MFN tariff or a higher specific duty rate applied once the quota allocation has been fully used. | Some frozen poultry products can face duties of up to 162.2% outside the quota, making imports commercially unviable. |
| Quota Period | The timeframe over which quota usage is measured and managed. | Most poultry TRQs operate on an annual basis, with quota balances resetting at the beginning of each quota year. |
| Quota Administration Method | The process used to allocate quota access, typically either First-Come-First-Served (FCFS) or through quota licences. | UK poultry quotas may use FCFS allocation, licence allocation, or a combination of both depending on the country of origin. |
| Quota Order Number | The unique reference number assigned to a specific tariff quota measure within the UK Trade Tariff. | Importers use the quota order number to identify the relevant quota linked to a particular HS code and country of origin. |
| Commodity Code Relevance | TRQs apply only to specific commodity codes or ranges of codes defined in the tariff schedule. | HS 0207.12 (Frozen Whole Chickens) and HS 0207.14 (Frozen Chicken Cuts) are subject to separate tariff quota measures and must be classified correctly to qualify. |
TRQ Check:
Before importing goods in agricultural or food categories, always check the Measures section of the UK Trade Tariff for the relevant commodity code. If a TRQ applies, the difference between the in-quota and out-of-quota rate can be commercially decisive. iCustoms’ iCDS solution flags TRQ measures automatically for every code in your product catalogue.
Anti-Dumping Duties Explained: How HS Codes Trigger Trade Remedy Measures
Anti-dumping duties are additional import charges imposed on goods that are being sold into a market at a price below their normal value in the exporting country, in a way that causes or threatens material injury to domestic producers. They sit on top of the standard customs duty and apply only to goods from specific origin countries that are found to be dumping under a formal trade remedy investigation.
In the UK, anti-dumping measures are administered by the Trade Remedies Authority (TRA), which was established after Brexit to take over the EU’s anti-dumping functions for UK trade. The TRA investigates dumping allegations, conducts reviews of measures inherited from the EU at Brexit, and can impose, extend, or terminate anti-dumping duties through a formal determination process. Anti-dumping duties are published in the UK Trade Tariff as trade remedy measures attached to the affected commodity codes.
Anti-dumping duties explained in relation to HS codes: the commodity code is the trigger. When an importer submits a customs declaration, the CDS checks the commodity code against the register of active trade remedy measures. If the code falls within a measure and the goods originate from an affected country, the anti-dumping duty is automatically added to the declaration. The importer cannot override this without a formal exemption or undertaking.
| Product Category | Affected HS Codes | Origin Countries | Trade Remedy Type | TRA Status (mid-2026) |
|---|---|---|---|---|
| Hot-Rolled Steel Flat Products | 7208 to 7211 | China, Russia, Ukraine, Brazil, Iran | Anti-Dumping and Countervailing Duties | Reviewed following Brexit. Certain measures have been maintained, amended, or replaced following recommendations from the Trade Remedies Authority (TRA). |
| Ceramic Tiles | 6907.21, 6907.22, 6907.23 | China | Anti-Dumping Duty | Subject to TRA review. Measures include both country-wide rates and company-specific duty rates. |
| Biodiesel (B20–B100 Blends) | 3826.00.10, 3826.00.90 | United States, Canada | Anti-Dumping Duty (Legacy EU Measure) | Under ongoing TRA review. Importers should verify the current measure status and applicable rates before importation. |
| Optical Fibre Cables | 8544.70 | China | Anti-Dumping Duty | Maintained following the post-Brexit transition and remains applicable to qualifying imports. |
| Monosodium Glutamate (MSG) | 2922.42 | China, Indonesia | Anti-Dumping Duty | A legacy trade remedy measure. Traders should confirm the latest TRA review outcome and applicable duty rates. |
| Aluminium Road Wheels | 8708.70 | China | Anti-Dumping and Countervailing Duties | Measures remain in force, with significant duty rates affecting importers in the automotive and vehicle components sector. |
The rates applied under anti-dumping measures vary significantly by company. Where the TRA has investigated individual exporters, company-specific duty rates (which may be lower than the country-wide rate) apply to goods from that exporter if the correct TARIC additional code is declared. Importers sourcing from manufacturers in affected countries should obtain the correct additional code from the exporter to avoid paying the higher residual country-wide rate.
HS Code Trade Compliance: Managing Risk Across the Supply Chain
HS code trade compliance encompasses more than getting the right duty rate. The commodity code of a product determines whether it is subject to export controls, trade embargoes, import licensing requirements, product standards checks, and anti-dumping measures. For businesses importing or exporting across multiple markets, trade compliance is the process of systematically ensuring that every shipment uses the correct HS code and that all the obligations attached to that code are met before goods move.
Maersk’s trade strategy guidance identifies HS code accuracy as the foundation of supply chain compliance. An incorrect HS code on a single shipment can trigger: a customs examination that delays the consignment, a demand for additional documentation, a retrospective duty assessment, an export control violation if the code covers dual-use goods that should have been licensed, or an inadvertent breach of trade sanctions if the incorrect code masks a controlled product.
| Compliance Area | How HS Code Triggers It | Consequence of Incorrect Code | iCustoms Solution |
|---|---|---|---|
| Customs Duty Calculation | The HS code determines the applicable MFN, preferential, or reduced tariff rate used to calculate customs duty. | Underpayments may result in retrospective duty demands and interest charges, while overpayments create unnecessary import costs. | iClassification helps identify the correct commodity code, while iCDS applies the correct duty rate during declaration processing. |
| Anti-Dumping Measures | The commodity code is checked against applicable UK trade remedy measures at the 8- or 10-digit level. | Failure to declare applicable anti-dumping duties can result in post-clearance assessments, penalties, and additional duty liabilities. | iCDS automatically flags applicable anti-dumping and trade remedy measures linked to the selected commodity code. |
| Export Controls (Dual-Use Goods) | Certain HS headings correspond to products regulated under UK strategic export control legislation. | Exporting controlled goods without the required licence may lead to enforcement action, shipment detention, fines, or criminal prosecution. | iClassification identifies potentially controlled goods and alerts exporters to applicable licensing requirements. |
| Import Licensing | Commodity codes identify goods requiring licences, permits, certificates, or prior authorisations. | Importing regulated goods without a valid licence can lead to seizure, delays, fines, or prosecution. | iCDS provides licence requirement alerts for commodity codes linked to controlled or regulated products. |
| Rules of Origin Compliance | The HS heading determines which Product-Specific Rule (PSR) applies when claiming preferential tariff treatment under a trade agreement. | Incorrect preference claims can result in retrospective duty demands and loss of preferential treatment. | The iCustoms Rules of Origin module cross-checks products against applicable trade agreement PSR requirements. |
| Tariff Rate Quota (TRQ) Allocation | The commodity code determines whether a TRQ applies and identifies the relevant quota measure. | Incorrect quota claims can result in reassessment at higher out-of-quota duty rates and additional customs liabilities. | iCDS performs real-time quota availability checks before declaration submission to support accurate TRQ claims. |
COMP Note:
Maersk’s trade compliance guidance identifies HS code accuracy as the single most important input in supply chain compliance programmes. A wrong code at the point of classification creates compounding errors across duty, licensing, preference, anti-dumping, and statistics. Building classification accuracy into procurement and logistics workflows, rather than correcting errors after the fact, is the most cost-effective compliance approach.
