How to export from the UK: a first-timer's guide.
Exporting from the UK for the first time looks more complicated than it is. Here's what you actually need, in plain English, and where people typically get stuck.
The basics: EORI number, commercial invoice, packing list
Three documents underpin almost every UK export shipment:
EORI number. An Economic Operators Registration and Identification number is your unique ID in the UK customs system. You need one to submit export declarations. Apply through HMRC for free, it usually takes a few days. If you are exporting as a business, sort this before anything else.
Commercial invoice. This is the document that says what you are exporting, how many, and what it is worth. It must be accurate, the declared value affects the import duty the buyer pays at the other end. A template commercial invoice is not complex, but the details must be right.
Packing list. A line-by-line breakdown of what is in each box or pallet: description, quantity, gross weight, dimensions. It supplements the commercial invoice and is used by customs at both ends to verify the cargo.
Container choice
Choosing full vs shared container
Once your paperwork is in order, the biggest practical decision is how to load your cargo.
A full container (FCL, Full Container Load) gives you a 20ft, 40ft or 40HC box to yourself. Everything inside is yours. It is the right choice if your cargo fills most of the container, if you need a controlled environment, or if the cargo is sensitive to other goods being loaded alongside it.
A shared container (LCL, Less than Container Load, also called groupage) puts your cargo in a container with other exporters' goods. You pay only for the cubic metres and weight you use. For first-time exporters sending a smaller volume, LCL is often significantly cheaper than booking a full box you don't need.
Not sure which? Tell us your cargo dimensions and weight and we'll tell you which works out cheaper for your shipment.
Classification
Commodity codes and why they matter
Every product that crosses an international border is assigned a commodity code, a numerical classification from the UK Trade Tariff that tells customs authorities exactly what the goods are. The code determines the rate of import duty and VAT the buyer will pay, and it appears on the export declaration.
Getting the commodity code wrong is one of the most common first-timer mistakes. An incorrect code can cause delays at the destination port, result in the wrong duty rate being charged, and create paperwork problems that are time-consuming to unwind.
You can look up commodity codes on the UK Government's Trade Tariff tool. If you are unsure which code applies to your product, tell us what it is and we will advise, or point you to the right place to confirm.
Declarations
What an export declaration is
An export declaration is the formal notification to UK customs that goods are leaving the country. It is submitted electronically through HMRC's Customs Declaration Service before the cargo arrives at the port. Without it, your goods cannot legally be loaded onto the vessel.
The declaration includes: your EORI number, the commodity code, a description and value of the goods, the destination country, and the exporter's details. It generates a movement reference number that the port uses to link your physical cargo to the customs record.
We arrange and manage export declarations through trusted partners as part of every shipment. You do not need to submit this yourself, but you do need to provide us with accurate cargo details, correct values and the right commodity codes so the declaration can be prepared correctly.
Avoid the pitfalls
Common first-timer mistakes
- No EORI number. Applying too late causes delays. Apply to HMRC as soon as you decide to export.
- Undervaluing goods on the commercial invoice. Declaring a lower value to reduce the buyer's import duty is customs fraud in most countries. It also means if the cargo is lost or damaged, your insurance payout is based on the declared value.
- Wrong commodity code. Take the time to confirm the correct code before the declaration is filed. Amending it after the fact is possible but creates extra work.
- Missing or inconsistent documents. The commercial invoice, packing list and export declaration must all agree on quantities, values and descriptions. Mismatches trigger customs queries at the destination.
- Leaving paperwork to the last minute. Export declarations must be filed before cargo arrives at the port. Turning up at the gate without a valid declaration means the shipment does not load.
Division of responsibility
What a shipping company does for you vs what you do yourself
What we do: arrange collection from your premises, book the container and sailing, prepare the export declaration through trusted partners, prepare any required certificates (ATR/EUR1 for Turkey), and coordinate import clearance at the destination. We keep you updated throughout and handle the whole job.
What you need to provide: accurate descriptions of your goods, correct declared values on the commercial invoice, and your EORI number (we'll remind you to get this sorted). For first shipments, we walk you through each document so nothing is missed.
The division is simple: you know your goods and their value; we know how to move them and keep them clear of customs problems.
Straight answers
First-time exporter questions
Do I need an EORI number to export from the UK?
Yes. An EORI (Economic Operators Registration and Identification) number is required to submit export declarations in the UK. You can apply for one free of charge through HMRC. It usually takes a few days to arrive. If you are exporting as a business, you almost certainly need one. We remind you to get this sorted well before your cargo is due to ship.
What is an export declaration?
An export declaration is the official notice to UK customs that goods are leaving the country. It is submitted electronically through HMRC's systems before the goods arrive at the port. The declaration includes details of what is being exported, its value, its commodity code and who is exporting it. We arrange and manage export declarations through trusted partners as part of your shipment.
What does a shipping company do for a first-time exporter?
A good shipping company will arrange collection from your UK premises, book the container and sailing, prepare the export documentation (commercial invoice guidance, packing list, export declaration through trusted partners), and coordinate import clearance at the destination.
