FMCG importers: how vape duty and the soft drinks levy reshape your cash cycle

Most UK importers who've been through a duty conversation before think in one currency: customs duty, payable at the border or deferred a month via a duty deferment account, occasionally suspended in a bonded warehouse. That mental model works fine for general goods. It breaks quietly for FMCG wholesalers bringing in vapes or soft drinks, because both product categories carry a second, separate liability that behaves by different rules entirely: excise duty.

Vaping Products Duty — the mechanics that catch people out

Vaping Products Duty (VPD) is scheduled to take effect from 1 October 2026, charged at £2.20 per 10ml of e-liquid. It is an excise duty, not a customs duty, and that distinction is the whole story. A customs warehouse — the facility that suspends ordinary customs duty and import VAT while goods sit in bond — does not suspend an excise liability. VPD needs its own separate approval: an excise warehouse or an HMRC-approved store operating under excise duty-suspension arrangements. Holding vape stock in an ordinary bonded warehouse and assuming the excise position is covered too is exactly the kind of assumption that surfaces badly at the worst possible moment.

There's a second date that matters as much as the first: from 1 April 2027, it becomes an offence to hold or sell unstamped vaping product. Stock that clears its duty point before VPD starts on 1 October 2026 doesn't carry the new duty — but if it's still sitting in a warehouse, unstamped, after 1 April 2027, that's a compliance problem regardless of when it landed. Importers holding vape stock across that window need both dates on the same calendar, not just the one that determines the duty rate.

The Soft Drinks Industry Levy — deferred by design, not by choice

The Soft Drinks Industry Levy (SDIL) works on an entirely different rhythm. It isn't collected at the border at all — it's reported and paid through a quarterly return, with payment due within 30 days of the period end. Averaged across a quarter, that works out to roughly 75 days from the point of import to the point the levy actually leaves the bank account, which is a materially longer window than most importers assume when they first price a soft drinks consignment.

The levy is banded on sugar content: drinks in the 5–8g-per-100ml range sit in the lower band, and anything above 8g sits in the higher one. That threshold isn't fixed indefinitely — it's due to tighten to 4.5g in 2028, and milk-based drinks, currently outside scope, are due to come into scope from January 2028. A soft drinks importer planning shelf life and reformulation timelines two years out needs those dates in the plan now, not as a surprise when the rules change.

Because SDIL isn't a border payment, it can't be suspended in a customs or excise warehouse the way VPD or ordinary customs duty can. It sits on its own track, credited through the return on exports rather than relieved at a warehouse door.

The trap isn't ignorance of the duty rate. It's assuming a customs warehouse — built for ordinary customs duty — automatically covers an excise liability it was never designed to touch.

Why this changes the cash-conversion cycle, not just the duty line

For a general importer, the cash-conversion cycle runs: pay (or defer) duty and VAT at import, hold stock for some number of days, sell, collect from the customer. FMCG importers in vapes or soft drinks are running two liabilities on two different clocks inside that same cycle — an excise duty that needs its own suspension approval and stamping regime, and a levy that arrives on a quarterly cycle regardless of when the stock actually sells. Treating both as "duty, roughly" and folding them into the same mental bucket as customs duty is how the funding gap gets underestimated.

The levers that close the gap are the same ones that work for any import — Postponed VAT Accounting, a duty deferment account, negotiated supplier terms, invoice finance against the sales ledger — but the shape of the gap they're closing is different, because two of the liabilities on the table (VPD and SDIL) don't move the way customs duty does. A funding plan built only around customs duty and import VAT will misjudge the timing on both.

What to actually plan around

Three things worth putting on paper before the next consignment lands: whether an excise suspension approval exists separately from any customs warehouse arrangement already in place; whether the SDIL registration is in order before the first liable import, given the quarterly-return timing rather than a border-payment one; and whether the compliance calendar — 1 October 2026 for VPD, 1 April 2027 for the unstamped-stock offence, the 2028 SDIL threshold and scope changes — is sitting against the actual stock programme, not filed separately from it.

Why the same levers still apply — just against a different shape

It's worth being clear that none of this means FMCG importers need an entirely new financing playbook. Negotiated supplier terms are still the cheapest funding in the chain, whatever the product. Postponed VAT Accounting still removes the import VAT leg from the border payment for anyone VAT-registered, vapes and soft drinks included. Invoice finance against the sales ledger still works the same way — an advance the day the invoice is raised, sized off the actual cash-conversion cycle. What changes for FMCG is the shape of the gap those levers are closing: an ordinary importer is funding a single duty-and-VAT event against a sale that might be forty-five days out. A vape or soft-drinks importer is funding that same event, plus an excise liability on its own suspension track, plus a levy that lands on a quarterly cycle regardless of when the stock actually moves. Stack all five levers — terms, PVA, deferment, bond-and-excise-suspension, invoice finance — against that fuller picture, and the consignment can often fund a meaningful share of itself. Stack them against the wrong picture, sized only for customs duty, and the gap shows up as a cash surprise mid-quarter.

None of this is tax advice, and the specific rates and registration steps sit with HMRC and a proper adviser. But the structural point stands regardless of who confirms the detail: excise duty and a sugar levy are not customs duty wearing a different hat, and a cash plan built as if they were will be short exactly where it matters.
