The clock matters more than usual this year. On 1 October 2026, Vaping Products Duty (VPD) lands at £2.20 per 10ml. It applies to every millilitre of liquid, whatever the strength. So zero-nicotine shortfills and 20mg nic salts now carry identical duty.
That single change reshapes production planning. Worse, it exposes a question many brand owners have avoided: is your current manufacturer actually built to grow with you?
In this article, we walk through five signs that your manufacturer may be holding you back. We also explain why the VPD deadline turns a “someday” problem into a “this quarter” one.
First, the deadline you can’t ignore
HMRC opened duty approvals on 1 April 2026. Crucially, the checks take at least 45 working days. Retail packs then need a physical duty stamp from 1 October, with full enforcement from April 2027.
Read that timeline again. A manufacturer that starts late cannot simply catch up. As a result, your route to market now depends on the right partner. They are already approved, already stamp-ready, and already planning fill sizes around the new duty.
So the real question is simple. Does your manufacturer move first, or do they wait for you to chase?
Sign 1: You’ve outgrown them
You launched with small batches. Now you need real volume, and the answers get vaguer. Lead times stretch. “Maybe next quarter” creeps into every call.
A growth partner thinks differently. They flex from a 10ml sample run to millions of finished units without drama. In short, your ceiling should never be their ceiling.
Sign 2: Compliance is a grey area, not a guarantee
Ask where your liquid is made. You should get a straight answer in one sentence. Think UK production, ISO 7 clean room standards, a genuine GMP process, and full testing.
When that answer wanders, your brand inherits the risk. Recalls, seizures, and duty-stamp errors all land on your label, not theirs. With VPD approaching, that exposure only grows.
Sign 3: You’re always the one chasing
You email once. Then you email again. Eventually, someone replies.
Sound familiar? Poor communication feels minor until a launch slips. Then it costs you shelf space, cash flow, and confidence. A strong partner updates you before you have to ask.
Sign 4: They can’t move with the market
The market keeps shifting. The disposable ban rewrote product formats. VPD is now pushing fill sizes toward smaller bottles and pods. Meanwhile, nicotine pouches keep growing fast.
Your manufacturer should help you ride these shifts, not anchor you to last year’s range. If a new format feels impossible, that hesitation is a warning sign in itself.
Sign 5: Every new idea becomes a problem
A new flavour. A faster turnaround. A fresh format for a retailer pitch.
Ideas like these should excite your manufacturer. Too often, though, they trigger excuses instead. The right team treats your next idea as the work, not an inconvenience.
What a real growth partner looks like
At Xyfil, we built our operation around one belief: when our customers grow, we grow with them. So we make and test everything here in Preston, under UK standards, with capacity that scales as you do.
We have helped hundreds of UK brands move from first batch to full scale. Some arrived with a single recipe. Others arrived mid-crisis, days from a stockout. In both cases, the fix started with the same thing — a manufacturer that moves first.
Right now, “moving first” means VPD readiness. So ask any potential partner three direct questions. Are you HMRC-approved? Are you ready for duty stamps on 1 October? Have you adjusted fill sizes for the new duty?
If the answers come back confident, you have a partner. If they stall, you have your sign.
The clock is the point
Most manufacturing problems can wait. This one cannot. The 45-day approval window and the October stamp deadline turn delay into lost sales.
So treat these five signs as a checklist, not a think-piece. Score your current manufacturer honestly. If two or more land, start a conversation now while the timeline still favours you.
We are happy to be that conversation. Book a free consultation, and we will tell you plainly whether Xyfil is the right fit. No pressure, no jargon — just a clear answer before the deadline decides for you. Get in touch today.
