1. How UK Import Duty Works: The Complete Picture

When goods enter the UK, customs duty is charged based on three factors:

1. What you are importing — determined by the commodity code
2. Where it comes from — the country of origin determines which duty rate applies
3. How much it is worth — the customs value (CIF basis) determines the duty amount

The UK operates its own independent tariff schedule — the UK Global Tariff (UKGT) — which replaced the EU Common External Tariff on 1 January 2021.

Types of Duty

Duty Type	How It Works	Example
Ad valorem	Percentage of customs value	6.5% of CIF value
Specific	Fixed amount per unit/weight	£15.80 per 100 kg
Compound	Combination of ad valorem + specific	8% + £12 per 100 kg
Anti-dumping	Additional duty on goods sold below fair value	22.5% on certain Chinese steel
Countervailing	Offsets foreign government subsidies	Variable by product/origin
Safeguard	Temporary protection against import surges	Quota-based tariff rate quotas

The Duty Rate Hierarchy

For any given import, the applicable duty rate follows this hierarchy:

1. Preferential rate — if a Free Trade Agreement (FTA) applies and Rules of Origin are met
2. Autonomous tariff suspension — temporary reductions for goods not produced in the UK
3. MFN (Most Favoured Nation) rate — the standard rate applied to all WTO members
4. Anti-dumping / countervailing / safeguard duties — applied on top of the above where applicable

2. Commodity Code Lookup Guide by Product Category

Every imported product must be classified with a 10-digit UK commodity code. This section provides a practical lookup guide for commonly imported product categories.

How to Use This Guide

1. Find your product category below
2. Identify the most likely HS chapter and heading
3. Use the UK Trade Tariff tool to drill down to the full 10-digit code
4. Verify the code matches your specific product

Food and Agricultural Products (Chapters 1-24)

Product Type	Typical Chapter	Common Headings	Key Classification Notes
Live animals	Ch 01	0101-0106	Species determines heading
Meat and edible offal	Ch 02	0201-0210	Fresh/chilled vs frozen matters
Fish and seafood	Ch 03	0301-0308	Preparation method affects code
Dairy products	Ch 04	0401-0410	Fat content determines subheading
Cereals	Ch 10	1001-1008	Seed vs consumption use
Coffee, tea, spices	Ch 09	0901-0910	Roasted vs unroasted for coffee
Fruit and nuts	Ch 08	0801-0814	Fresh vs dried vs preserved
Beverages and spirits	Ch 22	2201-2208	Alcohol content critical

Classification tip: Food products are classified primarily by what they are, not how they are packaged. A frozen chicken breast is classified under Ch 02 (meat), not Ch 16 (prepared meat), unless it is cooked or seasoned.

Chemicals and Pharmaceuticals (Chapters 28-38)

Product Type	Typical Chapter	Common Headings	Key Classification Notes
Inorganic chemicals	Ch 28	2801-2853	Chemical composition determines code
Organic chemicals	Ch 29	2901-2942	Molecular structure is key
Pharmaceutical products	Ch 30	3001-3006	Dosage form and active ingredient matter
Fertilisers	Ch 31	3101-3105	Nitrogen/phosphorus/potassium content
Essential oils and cosmetics	Ch 33	3301-3307	Function determines heading
Plastics	Ch 39	3901-3926	Primary form vs article matters

Classification tip: Pharmaceuticals in measured doses or retail packaging go to Ch 30. Bulk active ingredients stay in Ch 29.

Textiles and Clothing (Chapters 50-63)

Product Type	Typical Chapter	Common Headings	Key Classification Notes
Cotton yarn and fabric	Ch 52	5201-5212	Weight per m2 determines subheading
Man-made fibres	Ch 54-55	5401-5516	Filament vs staple fibre distinction
Knitted garments	Ch 61	6101-6117	Gender, garment type, and fibre content
Woven garments	Ch 62	6201-6217	Same criteria as Ch 61
Home textiles	Ch 63	6301-6310	Bedding, curtains, bags, etc.

Classification tip: The knitted vs woven distinction (Ch 61 vs 62) is the most common error in textile classification. Check the fabric construction method, not the garment style.

Metals and Metal Products (Chapters 72-83)

Product Type	Typical Chapter	Common Headings	Key Classification Notes
Iron and steel	Ch 72	7201-7229	Form matters: ingots, flat-rolled, bars, wire
Steel articles	Ch 73	7301-7326	Function of the finished article
Copper	Ch 74	7401-7419	Refined vs alloy; form matters
Aluminium	Ch 76	7601-7616	Unwrought vs wrought; alloy vs non-alloy
Tools and cutlery	Ch 82	8201-8215	Hand tools vs machine tools
Miscellaneous metal articles	Ch 83	8301-8311	Locks, fittings, clasps

Classification tip: Steel products follow a progression: raw materials (Ch 72) then manufactured articles (Ch 73). A steel bolt is Ch 73, not Ch 72.

Machinery and Electronics (Chapters 84-85)

Product Type	Typical Chapter	Common Headings	Key Classification Notes
Industrial machinery	Ch 84	8401-8487	Function determines heading
Computers and data processing	Ch 84	8471	Portable vs desktop; peripherals separate
Electrical equipment	Ch 85	8501-8548	Motors, generators, transformers
Consumer electronics	Ch 85	8517-8528	Phones, TVs, monitors
Parts and accessories	Ch 84/85	Various	Parts follow the machine they serve

Classification tip: Multi-function devices (e.g., a printer/scanner/copier) are classified by their principal function. Parts are classified with the machine unless they have their own specific heading.

Vehicles and Transport (Chapters 86-89)

Product Type	Typical Chapter	Common Headings	Key Classification Notes
Motor vehicles	Ch 87	8701-8716	Vehicle type and engine capacity
Vehicle parts	Ch 87	8708	Catch-all heading for parts
Aircraft	Ch 88	8801-8805	Weight and type
Ships and boats	Ch 89	8901-8908	Purpose and tonnage

Classification tip: Electric vehicles have specific subheadings. Battery packs for EVs may be classified separately from the vehicle depending on whether imported together or as spare parts.

5. Rules of Origin: Qualifying for Preferential Rates

Claiming a preferential duty rate requires proof that the goods genuinely “originate” in the FTA partner country. This section explains how origin rules work in practice.

Origin Determination Methods

Method	How It Works	Example
Wholly obtained	Product is entirely produced in one country	Fresh salmon caught in Norwegian waters
Change of Tariff Heading (CTH)	Non-originating materials are classified in a different HS heading to the finished product	Wooden furniture (HS 9403) made from imported timber (HS 4407)
Change of Tariff Subheading (CTSH)	Non-originating materials change at 6-digit level	Less strict than CTH
MaxNOM (Maximum Non-Originating Materials)	Non-originating materials cannot exceed a set percentage of the ex-works price	Car with max 45% non-originating content by value
Specific process	A defined manufacturing operation must occur	Textiles: garment must be manufactured from yarn

Origin Evidence by Agreement

Agreement	Document	Who Issues It	Validity
UK-EU TCA	Statement on Origin	Exporter (self-certification)	12 months; up to 12 months retrospectively
CPTPP	Certificate of Origin or Origin Declaration	Exporter or competent authority	12 months
UK-Japan CEPA	Origin Declaration	Approved exporter or any exporter (<£5,500)	12 months
UK-Australia FTA	Origin Declaration	Exporter (self-certification)	2 years
UK-New Zealand FTA	Origin Declaration	Exporter (self-certification)	2 years
DCTS	GSP Form A or origin declaration	Registered exporter (REX) in origin country	12 months

Practical Steps to Claim Preference

1. Check the FTA applies — Is the origin country party to an agreement with the UK?
2. Identify the origin rule — Look up the product-specific rule in the FTA annex
3. Verify compliance — Does the product actually meet the rule? (Get evidence from supplier)
4. Obtain origin evidence — Request the correct document from your exporter/supplier
5. Declare the preference — Use the correct preference code on your CDS declaration
6. Retain records — Keep origin evidence for at least 4 years (6 years for some FTAs)

6. Step-by-Step Duty Calculation Walkthrough

This section walks through the complete duty calculation process for any UK import.

Step 1: Classify the Goods

Determine the 10-digit UK commodity code using:

• The UK Trade Tariff tool
• Section 2 of this guide for the relevant product category
• HMRC’s Tariff Classification Service (0300 200 3700) for complex cases

Record: The full 10-digit commodity code

Step 2: Determine the Country of Origin

Identify where the goods were produced or substantially transformed — not where they were shipped from.

• If goods are manufactured in Vietnam and shipped via Singapore, the origin is Vietnam
• If goods are assembled in Poland using Chinese components, origin depends on whether sufficient processing occurred in Poland

Record: The country of origin (2-letter ISO code)

Step 3: Look Up the Applicable Duty Rate

Using the commodity code and origin, look up the rate:

1. Check for a preferential rate first — Does a UK FTA cover this origin country and product?
2. If no preference — Use the MFN (third-country) rate shown in the UK Trade Tariff
3. Check for additional duties — Anti-dumping, countervailing, or safeguard measures?
4. Check for suspensions — Is there an autonomous tariff suspension reducing the rate?

Record: The duty rate (percentage and/or specific amount)

Step 4: Calculate the Customs Value (CIF)

The customs value must be on a CIF basis — Cost, Insurance, and Freight to the UK port of arrival.

Invoice Terms	Adjustment Required
EXW (Ex Works)	+ inland transport to port of export + freight to UK + insurance
FCA (Free Carrier)	+ freight to UK + insurance
FOB (Free on Board)	+ freight to UK + insurance
CFR (Cost and Freight)	+ insurance only
CIF (Cost, Insurance, Freight)	No adjustment needed
DAP / DDP	Deduct UK inland transport; may need to deduct UK duty for DDP

Additional value adjustments:

• Add: buying commissions, assists (moulds, tools, materials provided to supplier), royalties, licence fees
• Add: packing costs borne by the buyer
• Deduct: post-import transport within the UK, construction/assembly costs after import

Currency conversion: Use HMRC monthly exchange rates, not your bank rate.

Record: Customs value in GBP

Step 5: Calculate Customs Duty

For ad valorem duties:

Customs Duty = Customs Value (CIF) x Duty Rate (%)

For specific duties:

Customs Duty = Quantity/Weight x Specific Rate

For compound duties:

Customs Duty = (Customs Value x Ad Valorem Rate) + (Quantity x Specific Rate)

Step 6: Calculate Import VAT

VAT Value = Customs Value + Customs Duty + Excise Duty (if applicable)
Import VAT = VAT Value x VAT Rate

Standard VAT: 20% | Reduced: 5% | Zero: 0%

Step 7: Calculate Total Import Charges

Total = Customs Duty + Import VAT + Excise Duty (if applicable)
       + Anti-Dumping Duty (if applicable) + Safeguard Duty (if applicable)

7. Worked Examples by Sector

Example 1: Importing Cotton T-Shirts from Bangladesh

Scenario: A UK retailer imports 5,000 cotton T-shirts from Bangladesh.

Item	Detail
Product	Men’s cotton T-shirts
Commodity code	6109.10.00.10
Origin	Bangladesh
Invoice terms	FOB Chittagong
Invoice value	USD 15,000
Freight to UK	USD 2,200
Insurance	USD 150

Step 1 — Customs value:

• FOB value: USD 15,000
• Freight: USD 2,200
• Insurance: USD 150
• CIF value: USD 17,350
• HMRC exchange rate (illustrative): 1 USD = £0.79
• Customs value: £13,706.50

Step 2 — Duty rate:

• MFN rate for 6109.10: 12%
• Bangladesh is a DCTS Comprehensive Preferences country
• DCTS rate: 0% (duty-free, quota-free)

Step 3 — Customs duty:

• Customs Duty: £0.00

Step 4 — Import VAT:

• VAT value: £13,706.50 + £0 = £13,706.50
• Import VAT: £13,706.50 x 20% = £2,741.30
• (Recoverable via VAT return or use PVA for nil cash flow impact)

Step 5 — Total import charges:

• Total: £2,741.30 (VAT only, recoverable)
• Effective landed duty cost: £0 per T-shirt

Saving vs MFN: Without DCTS preference, duty would have been £13,706.50 x 12% = £1,644.78

Example 2: Importing Steel Tubes from China

Scenario: A UK manufacturer imports 20 tonnes of seamless steel tubes from China.

Item	Detail
Product	Seamless steel tubes for construction
Commodity code	7304.31.80.00
Origin	China
Invoice terms	CIF Felixstowe
Invoice value	£42,000

Step 1 — Customs value:

• Already CIF: £42,000

Step 2 — Duty rate:

• MFN rate for 7304.31: 0% (suspended under UKGT)
• But check for trade remedies: UK Steel Safeguard Measures apply
• Safeguard: tariff rate quota (TRQ) — in-quota at 0%, over-quota at 25%
• Check current quota utilisation at GOV.UK trade remedies

Step 3 — Customs duty (assuming within quota):

• Customs Duty: £0.00

Step 3b — Customs duty (if quota exhausted):

• Safeguard duty: £42,000 x 25% = £10,500

Step 4 — Import VAT (within quota scenario):

• VAT value: £42,000
• Import VAT: £42,000 x 20% = £8,400 (recoverable)

Step 5 — Total import charges (within quota):

• Total: £8,400 (VAT only)

Step 5b — Total (quota exhausted):

• Total: £10,500 + £10,500 VAT on increased value = approx £19,950

Key lesson: Always check trade remedy measures. The base duty rate can be misleading when safeguard or anti-dumping duties apply.

Example 3: Importing Machinery from Germany (EU)

Scenario: A UK factory imports an industrial CNC milling machine from Germany.

Item	Detail
Product	CNC milling machine
Commodity code	8459.61.10.00
Origin	Germany (EU)
Invoice terms	DAP UK factory
Invoice value	EUR 185,000
UK inland transport	EUR 1,500
Freight (Germany to UK port)	EUR 3,800
Insurance	EUR 450

Step 1 — Customs value:

• DAP value: EUR 185,000
• Deduct UK inland transport: -EUR 1,500
• CIF equivalent: EUR 183,500
• HMRC exchange rate (illustrative): 1 EUR = £0.86
• Customs value: £157,810

Step 2 — Duty rate:

• MFN rate for 8459.61: 2.7%
• UK-EU TCA preferential rate: 0%
• Origin rule: CTH or MaxNOM 50%
• Requirement: valid Statement on Origin from German exporter

Step 3 — Customs duty:

• With TCA preference: £0.00
• Without preference: £157,810 x 2.7% = £4,260.87

Step 4 — Import VAT:

• £157,810 x 20% = £31,562 (recoverable)

Step 5 — Total:

• Total: £31,562 (VAT only, recoverable)
• Saving from TCA preference: £4,260.87

Key lesson: Always obtain the Statement on Origin from EU suppliers. Even low duty rates add up on high-value capital equipment.

Example 4: Importing Wine from Australia

Scenario: A UK wine merchant imports 1,200 bottles (75cl) of Australian Shiraz.

Item	Detail
Product	Red wine, bottled, 14% ABV
Commodity code	2204.21.42.00
Origin	Australia
Invoice terms	FOB Melbourne
Invoice value	AUD 18,000
Freight	AUD 3,600
Insurance	AUD 200

Step 1 — Customs value:

• CIF value: AUD 21,800
• HMRC exchange rate (illustrative): 1 AUD = £0.52
• Customs value: £11,336

Step 2 — Duty rate:

• MFN rate for still wine: £12.80 per hectolitre
• UK-Australia FTA preferential rate: £0.00 (eliminated)
• Volume: 1,200 x 0.75L = 900 litres = 9 hectolitres

Step 3 — Customs duty:

• With UK-Aus FTA preference: £0.00
• Without preference: 9 x £12.80 = £115.20

Step 4 — Excise duty:

• Wine 11.5-14.5% ABV: approximately £2.67 per 75cl bottle (check current rates)
• 1,200 bottles x £2.67 = £3,204 (not recoverable)

Step 5 — Import VAT:

• VAT value: £11,336 + £0 + £3,204 = £14,540
• Import VAT: £14,540 x 20% = £2,908 (recoverable)

Step 6 — Total:

• Total: £6,112 (£3,204 excise + £2,908 VAT)
• Excise duty is the major cost for alcohol imports — customs duty is minor

• UK-South Korea FTA preferential rate: 0%
• Must meet Rules of Origin (MaxNOM percentage)

Step 3 — Customs duty:

• With preference: £0.00
• Without: £32,500 x 6.5% = £2,112.50

Step 4 — Import VAT:

• £32,500 x 20% = £6,500

Step 5 — Total:

• With preference: £6,500 (VAT only)
• Without: £8,612.50
• FTA saving: £2,112.50 per vehicle

8. Anti-Dumping and Trade Remedy Duties

Anti-dumping and other trade remedy duties are applied on top of standard customs duty. They significantly increase import costs and are commonly overlooked.

Currently Active UK Trade Remedy Measures (Key Products)

Product	Origins Affected	Measure Type	Additional Duty Rate
Certain steel products	Various (China, India, Turkey, others)	Safeguard (TRQ)	25% over-quota
Aluminium extrusions	China	Anti-dumping	21.2%-45.6%
Biodiesel	Various	Anti-dumping	£52.47-£250.40/tonne
Certain fasteners (screws, bolts)	China	Anti-dumping	27.4%-85%
Welded tubes and pipes	Various	Safeguard	25% over-quota
Ceramic tableware	China	Anti-dumping	13.1%-36.1%
Bicycles	China	Anti-dumping	48.5%
E-bicycles	China	Anti-dumping	18.8%-79.3%
Rainbow trout	Turkey	Anti-dumping	7.2%-9.5%

How to Check for Trade Remedies

1. Look up your commodity code on the UK Trade Tariff tool
2. Check the “Measures” tab for the specific origin country
3. Monitor the Trade Remedies Authority for new investigations
4. Subscribe to TRA notifications for product categories you import regularly

9. Customs Valuation: Getting It Right

Customs valuation errors are the second most common cause of duty miscalculation after commodity code errors.

The Six Valuation Methods (in order of preference)

HMRC requires you to use Method 1 wherever possible. You may only move to the next method if the previous one cannot be applied.

Method	Basis	When Used
1. Transaction value	Price actually paid or payable	Default for most imports (90%+)
2. Transaction value of identical goods	Recent price for identical goods	When Method 1 is rejected
3. Transaction value of similar goods	Recent price for similar goods	When Methods 1-2 unavailable
4. Deductive method	UK selling price minus deductions	When Methods 1-3 unavailable
5. Computed method	Cost of production + profit	Rarely used; requires overseas data
6. Fall-back method	Reasonable adjustment of Methods 1-5	Last resort

Common Valuation Pitfalls

Pitfall	Impact	How to Avoid
Using FOB instead of CIF	Understated value	Always add freight and insurance
Omitting royalties	Understated value	Review all licensing agreements
Ignoring assists (tooling, moulds)	Understated value	Track buyer-supplied items
Wrong exchange rate	Over or understated	Use HMRC monthly rates only
Related-party pricing	Customs may reject value	Maintain transfer pricing documentation
Discounts not at arm’s length	May be disallowed	Document commercial rationale

10. Duty Relief and Suspension Schemes

Several mechanisms can reduce or eliminate duty on specific imports.

Autonomous Tariff Suspensions

The UK government periodically suspends duties on products not manufactured domestically in sufficient quantities. These are automatic — no application required.

• Published in the UK Trade Tariff as a £0.00 duty rate
• Typically cover raw materials and industrial inputs
• Reviewed periodically; can be introduced or removed

Returned Goods Relief

Goods originally exported from the UK and re-imported within 3 years may qualify for duty-free re-import, provided:

• They are in the same condition as when exported
• No drawback or other export benefit was claimed

Inward Processing (IP) Relief

Duty suspension on imported materials used in manufacturing, where the finished goods are:

• Re-exported from the UK, or
• Released to free circulation (duty payable on finished product instead)

End-Use Relief

Reduced or zero duty on goods imported for a specific approved use (e.g., certain chemicals for industrial use).

Onward Supply Relief (OSR)

For goods imported into Northern Ireland that are not “at risk” of entering the EU single market — eliminates the need to pay EU duty rates.

11. Common Calculation Mistakes and How to Fix Them

Mistake	Impact	Fix
Claiming preference without origin evidence	HMRC rejects preference; full MFN duty charged retrospectively	Always obtain and verify origin documents before importing
Ignoring safeguard quotas on steel	25% unexpected duty charge	Check quota fill levels before shipping
Applying the wrong exchange rate	Over/underpayment of duty	Use HMRC rates published at gov.uk, not your bank or xe.com
Confusing origin and dispatch	Wrong duty rate applied	A product made in China and shipped via the Netherlands has Chinese origin
Not checking for anti-dumping duties	Massive underpayment discovered at audit	Check TRA measures for every new supplier/origin combination
Using 6-digit HS codes instead of 10-digit	Duty rate lookup fails or returns wrong rate	Always drill down to the full 10-digit UK commodity code
Forgetting to add freight/insurance to FOB	Customs value too low; potential penalty	Build CIF adjustment into your standard import process
Not accounting for excise duty on alcohol/tobacco	Significant cost omission	Check excise rates separately — they apply alongside customs duty

12. Quick Reference: Duty Calculation Cheat Sheet

The Formula

1.  Customs Value (CIF)  = Invoice Value + Freight + Insurance + Adjustments
2.  Customs Duty          = Customs Value x Duty Rate
3.  Excise Duty           = Per unit/volume rate (if applicable)
4.  Import VAT            = (Customs Value + Customs Duty + Excise) x 20%
5.  Total Import Charges  = Customs Duty + Excise + Import VAT
