How Customs Duties Work for UK Importers

How Customs Duties Work for UK Importers

A plain-English breakdown of import duty, VAT, HS codes, and the £135 threshold change every Shopify seller needs to know

Sourcing from China is one of the most profitable moves a Shopify seller can make — until a customs bill lands and the margin evaporates. Understanding how UK import duties actually work, before your first shipment clears, is the difference between a healthy business and a very expensive lesson.

Why UK Customs Duty Matters More Than Ever

The regulatory landscape for UK importers is shifting fast. Post-Brexit customs rules, a changing £135 de minimis threshold, and tighter HMRC scrutiny have created a compliance environment that catches even experienced sellers off guard. If you're running a Shopify store and sourcing products from China — whether through 1688, Taobao, or Tmall — understanding the duty framework is not optional. It's part of your unit economics.

This guide cuts through the jargon and gives you the concrete knowledge you need to calculate your real landed cost, avoid compliance traps, and plan your sourcing strategy with confidence.

The Basics: What Are UK Import Duties?

UK import duties (also called customs duties or tariffs) are taxes charged by HMRC on goods entering the United Kingdom from outside the country. The rate depends on the type of product, its country of origin, and the applicable trade agreement — and is applied to the customs value of the goods, which includes the cost of the item plus insurance and freight.

Since leaving the EU's Customs Union in January 2021, the UK has operated its own framework: the UK Global Tariff (UKGT). This sets out the duty rate for every type of goods imported from countries with which the UK does not have a preferential trade agreement. China is one of those countries — meaning most goods sourced there attract the full UKGT rate.

How Duty Rates Are Calculated

There is no single flat rate. The exact duty rate that applies to your goods is determined by the commodity code — a 10-digit number drawn from the international Harmonised System (HS). This code classifies your product precisely, and tells UK customs exactly what duty percentage applies.

  1. Find your commodity code on the UK Government's Trade Tariff Service.
  2. Look at the "Third Country Duty" rate — this is the rate that applies to imports from China.
  3. Multiply that percentage by your customs value (goods cost + shipping + insurance).
  4. Add 20% import VAT on top of the customs value plus any duty already applied.
Rule of thumb: Your landed cost is not just the factory price. It's factory price + shipping + insurance + customs duty + import VAT. Every component matters when you're pricing for profit.

Indicative Duty Rates by Product Category

Duty rates vary considerably by product category. Here's a quick reference for the most common Shopify product niches:

Product Category Indicative UKGT Rate Notes
Electronics & computers 0% – 3.7% Many components enter duty-free
Clothing & textiles 8% – 12% Among the highest for consumer goods
Footwear 8% – 17% Varies by material and construction
Toys & games 0% – 4.7% UKCA marking also required
Home & garden 0% – 6.5% Wide range depending on materials
Sporting goods 2% – 6% Check per item — categories vary

These are indicative ranges only — always verify your specific HS code before committing to a product. Getting the wrong commodity code is one of the most common and costly mistakes importers make.

The £135 Threshold: What It Is and What's Changing

This is the rule that affects Shopify dropshippers most directly. Currently, goods imported in a consignment worth £135 or less are exempt from customs duty at the border. Above £135, standard customs duty and import VAT both apply.

However, this is about to change in a significant way. The UK Government confirmed on 13 July 2026 that the £135 de minimis threshold will be repealed and replaced with a new mandatory customs framework for low-value imports, with implementation targeted by October 2028 at the latest. Draft legislation has already been published by HMRC.

What does this mean practically? Once the reform kicks in, even small individual parcels sourced directly from China will be subject to customs duty for the first time. For dropshippers running a direct-to-consumer model, this will directly increase landed costs on every low-value shipment.

  • The reform removes customs duty relief on consignments of £135 or less
  • Import VAT treatment for these goods is not changing — VAT already applies at the point of sale for low-value imports
  • New data and compliance requirements will accompany the change, including item-level product data submitted before goods arrive in the UK
  • Overseas sellers will require a UK fiscal representative with joint and several liability under the new framework

The direction of travel is clear. If your business model relies on sub-£135 duty-free imports, now is the time to model what your margin looks like once duty applies — and to explore consolidating shipments and building a more resilient sourcing structure.

Import VAT: The 20% You Can Reclaim

Import VAT is the largest tax cost for most UK importers — and the most misunderstood. The standard rate is 20%, and it's calculated not just on the goods value, but on the full customs value including shipping, insurance, and any import duty already charged. So VAT compounds on top of everything else.

Here's the good news: if your business is VAT-registered, you can reclaim import VAT in full through your VAT return. This means that for VAT-registered businesses, import VAT is ultimately a cash flow issue rather than a permanent cost — you pay it to release the goods, then recover it from HMRC.

Postponed VAT Accounting (PVA): The Cash Flow Game-Changer

Introduced post-Brexit, Postponed VAT Accounting is a mechanism that lets VAT-registered importers account for import VAT on their regular VAT return, rather than paying it upfront at the border. Under PVA, you declare the VAT as both input and output tax on the same return — meaning it cancels out, and no cash leaves your account at the point of import.

To use PVA, provide your EORI number and VAT number to your freight forwarder or customs agent before clearance. It's a straightforward process and it protects your working capital significantly, especially when you're importing in bulk from China.

The Documents You Must Have Right

HMRC requires a customs declaration for all goods entering Great Britain from outside the UK. Missing or inaccurate paperwork is the leading cause of delays and penalties — and more delays in 2026 are caused by supplier errors than importer errors. Make sure your supplier understands exactly what you need.

  • Commercial invoice — must clearly describe the goods, show seller and buyer details, declared values, currency, and delivery terms
  • Packing list — helps customs identify the physical makeup of the shipment, including package counts and weights
  • EORI number — you must have an Economic Operator Registration and Identification number to import into the UK; apply online at GOV.UK
  • Commodity (HS) code — the correct 10-digit code for every product line
  • Certificate of origin — required to substantiate the declared country of origin, which determines which duty rate applies

The Customs Declaration Service (CDS) is now the UK's sole customs platform. All import declarations go through CDS — ensure you or your customs agent are set up correctly before your first shipment lands.

Anti-Dumping Duties: The Hidden Risk for China Imports

This is the silent killer that catches too many first-time importers. On top of standard UKGT rates, the UK imposes anti-dumping duties on specific Chinese goods where HMRC has determined that goods are being sold below fair market value. These additional duties can be substantial — sometimes doubling or tripling the total duty bill on affected products.

Anti-dumping duties apply on a per-category basis and are not always obvious. If you're importing goods in categories like steel products, ceramics, certain chemicals, solar panels, or electric bicycles, verify whether anti-dumping measures apply before you place your order. The UK Trade Tariff will show any additional measures next to the standard duty rate for the relevant commodity code.

If you need guidance on navigating HS code classification and verifying duties before you commit to a supplier, the Piratify sourcing workflow is built around exactly this — validating product viability including landed cost before purchase.

Incoterms: Who Is Responsible at the Border?

The Incoterm on your purchase order determines who handles import formalities and bears the cost:

  • DDP (Delivered Duty Paid) — your supplier handles all customs clearance and pays the duty. You receive the goods clear. Simple, but you usually pay a premium for it, and you lose visibility into the actual duty being paid.
  • DAP (Delivered at Place) — goods are delivered to your door or warehouse, but import duty and clearance are your responsibility as the importer of record.
  • EXW (Ex Works) — you take full responsibility from the factory gate onwards, including all freight and customs.
  • FOB (Free On Board) — your supplier loads goods onto the vessel; you manage freight and customs from that point.

Most experienced Shopify sellers sourcing from China prefer FOB or DAP — you maintain control over the import process, which gives you transparency on costs and the ability to use your own customs agent. DDP can hide costs and makes it harder to use PVA effectively.

A Practical Landed Cost Formula

Before you finalise any product decision, run this calculation:

  1. Start with your FOB unit cost (factory price)
  2. Add freight cost per unit (sea or air)
  3. Add insurance (typically 0.5–1% of goods value)
  4. This gives your Customs Value (CIF)
  5. Apply your commodity duty rate to the CIF value
  6. Apply 20% VAT to (CIF + duty)
  7. If VAT-registered, subtract VAT — it's recoverable
  8. Add customs clearance fee (broker fee, typically £35–£100 per shipment)
  9. Add any last-mile delivery cost

The result is your true landed cost per unit. If your retail margin is still compelling after this exercise, you have a viable product. If it isn't, adjust your supplier pricing, your product category, or your shipping method — not your margin expectations.

FAQ

Do I pay customs duty on every order I import from China?

Currently, consignments valued at £135 or less are exempt from customs duty (though import VAT may still apply at the point of sale). Consignments above £135 attract both standard customs duty (based on your commodity code) and 20% import VAT. This threshold is confirmed to be abolished by October 2028, after which duty will apply to low-value imports too.

What is an EORI number and do I need one?

An EORI (Economic Operator Registration and Identification) number is a unique reference number used to track imports and exports in the UK. If you are importing goods from outside the UK, you will need an EORI number. You can apply online via GOV.UK and typically receive it immediately, unless HMRC needs to carry out additional checks.

Can I reclaim the import VAT I pay on goods from China?

Yes — if your business is VAT-registered. Import VAT is fully reclaimable through your VAT return. Better still, use Postponed VAT Accounting (PVA) to avoid paying VAT at the border at all: you simply declare it on your next VAT return as both input and output tax, meaning the net cash impact is zero at the time of import. This is available to all VAT-registered UK importers and is strongly recommended for anyone importing regularly from China.
