Packaged vs unpackaged vaping liquid: how duty is calculated

A plain-English guide for Canadian vaping product licensees: what separates bulk vaping substance from retail-ready containers, exactly when duty is imposed, and how the per-container calculation works, with worked examples at every common size.

Packaged vs unpackaged: the core distinction

Under the excise duty framework for vaping products in the Excise Act, 2001, the single most important line in your inventory is whether a vaping substance is unpackaged or packaged. That status determines whether duty has been triggered, and how much you owe.

• Unpackaged vaping substance is bulk liquid still in production, mixed, decanted or stored in drums and totes, held by or transferred among vaping product licensees. It is not yet duty-paid and carries no excise stamp.
• Packaged vaping product has been put into its immediate container (the pod, cartridge or bottle a consumer will actually buy), ready for retail sale.

Everything before packaging is bulk inventory you move and account for; everything at and after packaging is a finished, dutiable unit. Getting this boundary right is the whole game, because duty is calculated on the immediate container, not on the batch you mixed it from.

When vaping duty is imposed

Vaping duty is imposed at the moment the product is packaged into its immediate container and stamped, before it enters the duty-paid market. Up to that point the bulk vaping substance is unpackaged and not yet liable for duty, which is why licensees can hold it and transfer it between one another without duty being payable.

In practice the chain runs: manufacture bulk substance → hold it as unpackaged inventory → package it into immediate containers → apply the vaping excise stamp → duty becomes payable → the product enters the duty-paid market. The stamp is the visible signal that duty has been accounted for. See our companion guide on vaping excise stamps in Canada for how stamping ties into this step.

How vaping duty is calculated

Duty is charged on the volume of vaping substance in each device or immediate container, in a two-tier bracket. The federal rate below has applied since July 1, 2024. In a specified vaping province, an additional duty equal to the federal amount is layered on top, effectively doubling the rate.

• First 10 mL of a container → $1.12 per 2 mL (or fraction thereof).
• Volume over 10 mL → $1.12 per 10 mL (or fraction thereof).
• In a specified vaping province, add an equal additional duty → roughly $2.24 per 2 mL on the first 10 mL and $2.24 per 10 mL above it (combined).

“Or fraction thereof” means you round up to the next whole unit. A 2.5 mL pod is charged as two 2 mL units, and an 11 mL container is five 2 mL units (first 10 mL) plus one 10 mL unit for the remaining 1 mL.

Worked example: a 30 mL bottle

• First 10 mL → 5 × $1.12 = $5.60 federal
• Remaining 20 mL → 2 × $1.12 (per 10 mL) = $2.24 federal
• Federal duty = $7.84. In a specified province, add an equal $7.84 → $15.68 combined.

Worked examples by container size

Because duty is per immediate container, the same volume of bulk liquid yields different total duty depending on how you package it. The table below shows the federal duty and the combined (specified-province) duty for common container sizes.

Federal amounts assume a non-specified destination; combined amounts apply where a specified vaping province adds its equal additional duty. Combined is exactly twice the federal figure.

Federal vs combined (specified-province) duty

The federal duty applies to every dutiable vaping product across Canada. Where a product is destined for a specified vaping province (a province or territory that has joined the coordinated vaping duty system), an additional vaping duty equal to the federal amountis imposed, and the product carries that province’s own excise stamp instead of the peach-coloured “Canada” stamp. The combined burden is therefore about double the federal figure, which is why the table above lists both columns.

Why packaged vs unpackaged tracking matters for the B600

The monthly B600 Vaping Duty and Information Return is built around an inventory reconciliation. You account for every quantity of vaping substance that moved through your operation: manufactured, received, used, packaged, stamped, sold, exported and disposed of, and the return derives the duty payable from it.

Because duty is only payable on packaged, stamped product, keeping your unpackaged bulk separate from your packaged finished goods is what makes the return add up. If you cannot show how much bulk substance you held, how much you packaged, and how many stamps you applied, your duty figures will not reconcile, and that is exactly what a CRA review probes. Our B600 filing guide walks through the return line by line.

That separation is what EXCIVY automates: it tracks unpackaged and packaged liquid by volume, counts stamps by type and province, and calculates duty payable per container as you record inventory, so your B600 figures reconcile themselves and a review is a non-event instead of a scramble.
