Most importers get the compliance questions right long before they get the cash-flow question right. They know their commodity code, they have argued about whether the quote was FOB or DDP, and they have the CE and UKCA paperwork in order. Then the first reasonably large container lands and a bill arrives that has to be paid before the goods will move — and the stock that was supposed to fund it is still sitting at the port.
Nothing has gone wrong. This is simply how import charges work by default, and the default is the expensive option. The mechanisms that fix it are unglamorous and they do not reduce what you owe by a penny. They change when it leaves your account, which on a growing import book matters more than the rate does.
Three separate charges, often treated as one
The first useful step is to stop thinking of it as a single import bill. There are three distinct things, with different rules and different timing.
Customs duty, which depends on the commodity code and the country of origin. It is a real cost — you never get it back — and it is the one that classification actually determines. We have gone through getting that right in the commodity codes piece, because a misclassification is a duty rate you pay on every shipment thereafter.
Import VAT, which is charged on the landed value of the goods including duty and freight. For a VAT-registered business this is not a cost at all in the end, because it is recoverable. It is purely a timing problem, and it is usually the largest of the three numbers.
Freight, handling and clearance charges, billed by the forwarder and the agent, which have their own payment terms entirely separate from HMRC's.
Conflating the second with the first is the common and expensive mistake. Import VAT feels like a tax bill and behaves like a loan you have made to the government.
Postponed VAT accounting: the one most importers should be using
Postponed VAT accounting lets a VAT-registered business account for import VAT on its VAT return rather than paying it at the border and reclaiming it later. The same figure goes on as both output and input tax, and the net effect on a fully taxable business is nil.
The difference is entirely in the timing, and it is substantial. Without it, you pay import VAT when the goods clear and wait until your next return — potentially the better part of a quarter — to get it back. With it, the money never leaves at all.
It is not automatic. It has to be elected on the customs declaration, which in practice means your broker or forwarder has to be told to use it, shipment by shipment, as part of their standing instructions. The number of businesses that are entitled to it and still paying VAT at the border because nobody ever told the agent is not small. If you are importing and are not certain which way your declarations are being made, that is a five-minute question worth asking this week.
You will also need the monthly statements that evidence what you declared, which are downloaded from the government's customs portal rather than posted to you. Someone has to own that job each month, or the figures on the VAT return are guesses.
Duty deferment: for the money you genuinely do owe
Duty is not recoverable, so there is no equivalent trick. What a duty deferment account does is let the charges across a month be settled by a single direct debit afterwards, instead of each consignment being paid for before it will be released.
Two things make that worth having. The obvious one is that it gives you a few weeks between the goods arriving and the money going, which is roughly the gap between landing stock and selling it. The less obvious one is that it stops clearance being gated on a payment: without deferment, a consignment waits until somebody notices the request and pays it, and a container sitting at a port accruing storage while an invoice goes unapproved is a pure, avoidable loss.
Setting one up involves an application and, depending on the size of the limit and your circumstances, a financial guarantee. Many forwarders will also let smaller importers clear against the forwarder's own deferment account for a fee, which is a reasonable staging post before you hold your own.
Where this interacts with Incoterms
This is the connection people miss. An Incoterm decides who is responsible for clearing the goods and paying the charges, which decides whether any of the above is available to you at all.
Buy DDP and the supplier handles import clearance. That sounds like it removes the problem, and for cash-flow purposes it partly does — but it also means the declaration is not yours, you are not the importer of record, and the recovery of import VAT becomes considerably more awkward than simply putting it on your own return. Convenience bought at the wrong point in the chain.
Buy FOB and you are the importer of record. You carry the clearance, and you get the full benefit of postponed accounting and deferment. For anyone importing with any regularity, that is the right side of the trade — and it is one of the practical reasons the FOB-and-handle-it-yourself route tends to win once volumes are more than occasional. Our Incoterms piece covers who carries what.
The working-capital arithmetic nobody does up front
Before the next order, it is worth writing down the actual cash timeline rather than the lead time. Deposit paid at order. Balance paid before or on shipment. Freight invoiced on arrival. Duty and VAT at clearance. Then stock on a shelf, then a sale, then — if you sell on trade terms — another thirty or sixty days before the money comes back.
On a container of reasonable value that is a long time to be out of pocket, and the gap is what constrains how fast an import business can grow. It is also why the timing mechanisms matter more than shaving a little off the unit price: eliminating the import VAT outlay and deferring the duty can be worth more to a growing importer than a better quote on the goods.
How we handle it
We import directly from factories across Asia for our own brands and for clients, so landed cost and the cash timeline behind it are part of how we quote rather than a surprise afterwards. We would always rather set out the real timeline — deposit, balance, freight, duty, VAT, and when stock actually turns into money — than present a unit price that ignores the half of the cost that is timing.
None of the above is tax advice, and the thresholds and conditions are worth confirming with your accountant for your own circumstances. But if you are planning imports and are not sure the cash timeline works, talk to us and we will work it through with you alongside the lead times.
