Calculate duty from product volume
Calculate Vape Duty from each product or variation's liquid volume using your configured duty rate.
WooCommerce Plugin
Add UK Vaping Products Duty to WooCommerce prices before 1 October 2026.
UK Vaping Products Duty starts on 1 October 2026 at 22p per ml. Standard WooCommerce tax classes cannot calculate a duty based on liquid volume. The new vape tax from 1 October 2026 is based on liquid volume rather than a percentage of the product price. Vape Duty Manager is a WooCommerce plugin that calculates Vape Duty from product volume, including individual variations, lets you preview the whole catalogue before prices change, and apply or schedule the new prices when you are ready. Sale prices remain sale prices, while VAT continues to be handled by WooCommerce.

Why a plugin?
WooCommerce tax classes work well with percentage-based taxes such as VAT. Vaping Products Duty is different because it is based on liquid volume — a fixed amount per millilitre, not a percentage of the selling price.
A 10ml bottle, a 50ml shortfill and a 2ml prefilled pod carry different fixed duty amounts even when their selling prices are similar. At 22p per ml, the duty on a 10ml bottle is £2.20, on a 50ml shortfill it is £11.00, and on a 2ml pod it is £0.44.
Trying to reproduce those fixed amounts with tax classes, or by manually repricing products and variations, creates unnecessary work and risk ahead of 1 October 2026. Vape Duty Manager handles the volume calculation so your WooCommerce prices reflect the correct duty for each product and variation.
Duty example
At the current Vaping Products Duty rate, duty is calculated from the volume of vaping liquid. This table shows the duty amount only — your final selling price depends on your base product price and tax configuration.
| Product volume | Vape Duty |
|---|---|
| 2ml | £0.44 |
| 10ml | £2.20 |
| 50ml | £11.00 |
| 100ml | £22.00 |
For a 50ml bottle: 50 × £0.22 = £11.00 Vape Duty added to the ex-VAT product price.
VAT on duty is then calculated on the duty-inclusive taxable amount through WooCommerce, using your existing tax settings. This page is not a retail price calculator — base prices and tax configuration vary between stores.

Who it's for
Vape Duty Manager is for businesses selling vaping products through WooCommerce that need to incorporate UK Vaping Products Duty into their product pricing before customers reach checkout.
Retailer mode is the standard workflow for shops that sell vaping products on which duty has already been accounted for in the supply chain. Those retailers still need to reprice their WooCommerce catalogue — but their obligations differ from manufacturers or importers who account for duty at source.
Vape Duty Manager Pro will also add Manufacturer mode and additional reporting for businesses that manufacture vaping products or need to account for upstream duty responsibility.
Scope
Vape Duty Manager manages WooCommerce pricing and internal records. It does not submit Vaping Products Duty returns, register your business with HMRC, purchase duty stamps or calculate import and landed costs.
System requirements

FAQ
Common questions about Vape Duty Manager for WooCommerce.
UK Vaping Products Duty starts on 1 October 2026. Vape Duty Manager lets you prepare product pricing in advance and schedule the change to go live on that date.
The current rate is 22p per ml — £2.20 per 10ml of vaping liquid. VAT is then charged on the duty-inclusive taxable amount through your normal WooCommerce tax settings.
No. WooCommerce tax classes are designed for percentage-based taxes such as VAT. Vaping Products Duty is calculated from liquid volume, so a fixed amount per millilitre — not a percentage of the product price.
Free allows plugin-managed duty pricing on up to 100 duty-applied SKUs at a time. If you are at the cap, you cannot apply duty to additional products until you remove duty from some existing ones or upgrade to Pro. If a single apply scope contains 101 or more eligible SKUs, apply and schedule are blocked — Free does not apply only the first 100. You can still preview any scope and manually edit prices in WooCommerce.
Yes. Every calculate run is a dry run. You review the full preview table, summary counts and readiness checklist before apply or schedule is available.
Yes. You can schedule approved duty pricing to go live automatically on 1 October 2026 within the Free edition's 100 duty-applied SKU limit. Larger catalogues will need Vape Duty Manager Pro, which is coming soon.
Yes. Each purchasable variation is evaluated individually when volumes differ. Sale prices stay as sale prices — duty is applied to both regular and sale prices without converting a sale back to a regular price.
Yes. The plugin respects each product's tax status, tax class and your WooCommerce tax configuration. It supports VAT-inclusive and VAT-exclusive catalogue pricing. Duty is added to the ex-VAT price, and WooCommerce calculates VAT on the duty-inclusive amount.
Yes. Rollback restores prices from immediately before one completed batch. Remove Vape Duty restores saved base prices catalogue-wide. Both require preview and typed confirmation.
No. The full Audit area — including sales and duty reports, activity log, refund duty review, transition stock and duty responsibility views — is Pro only. Free includes batch history, price history and order-line duty snapshots.
Classic cart and checkout templates are supported in Free. Live duty totals in Cart and Checkout Blocks will be part of Vape Duty Manager Pro, which is coming soon.
A Pro-only operating profile for businesses that manufacture vape products rather than only retailing them. It changes default duty-responsibility behaviour, guidance copy and how reporting presents retailer-accountable vs upstream-paid amounts. Free uses Retailer mode only.
Vaping liquids subject to Vaping Products Duty include 0mg products. Hardware and other non-liquid products are not liable and do not count towards the Free edition's duty-applied SKU limit.
No. Vape Duty Manager is an operational WooCommerce tool. It helps you calculate and apply duty-inclusive prices and keep internal records. It does not prepare, validate or submit returns to HMRC.
Product data, prices, sales information and plugin records remain on your WordPress installation in the current release. No licence server, telemetry endpoint or cloud database is contacted.
