Answer first
For UK vape trade buyers, traceability connects each product reference and pack to its batch, supplier, receipt, location and onward sale. This creates an audit trail for stock control, duty records and corrective action. A batch number is required on relevant nicotine-vape packs; an internal SKU helps manage the record, but does not replace it.
Key Takeaways
- Batch numbers identify a production grouping and must appear on each unit packet and container pack of electronic cigarettes and refill containers covered by the relevant rules.
- A SKU is your internal stock key. Map it to the exact pack configuration and batch, rather than treating a barcode or product name as enough evidence.
- Keep a one-up, one-down trail: record who supplied the goods and, where applicable, which customer received each batch or controlled stock movement.
- Vaping Products Duty records require a durable audit trail. HMRC says relevant records and supporting evidence must be retained for at least six years.
Understand the identifiers before stock arrives
Use batch, SKU and pack identifiers together because they answer different questions. A batch number links goods to a defined production grouping. Regulation 37 of the Tobacco and Related Products Regulations 2016 requires it on each unit packet and container pack of electronic cigarettes and refill containers. It lets a buyer isolate affected stock without treating all similarly named goods as interchangeable.
A stock keeping unit (SKU) is an internal product reference. Map it to a stable pack specification. Create a new SKU or controlled revision when the pack, contents or market variant changes. A SKU supports stock control; it does not replace a batch number.
A pack record describes the sellable unit and hierarchy: retail pack, case or shipper, and pallet or consignment. A barcode can identify a product type but may not separate batches. Retain a pack image or scan showing the batch marking, plus documents connecting goods to the transaction.
For nicotine-containing products in Great Britain, MHRA rules say e-cigarettes and e-liquids must be notified and published before sale. A producer can include a manufacturer, importer or business rebranding a product as its own. Preserve references used for due diligence; a public listing does not replace checking received goods. See MHRA notification and private-label roles and UK vape packaging and labelling.
The comparison below helps buyers assign each field correctly.
| Record element | What it identifies | Minimum practical link to retain | Why it matters |
|---|---|---|---|
| Batch number | A defined production grouping | SKU, receipt date, supplier and quantity | Isolates affected physical stock |
| SKU | Your controlled product and pack reference | Pack specification, barcode if used and active/obsolete status | Prevents catalogue records from merging unlike packs |
| Pack/case identifier | Retail pack, inner, shipper or pallet hierarchy | Batch, pack count and storage location | Supports counts after cases are split |
| Transaction record | Receipt, movement, sale, return or disposal | Date, counterparty, quantity and relevant batch/SKU | Provides the supply-chain audit trail |
Record each receipt, movement and status change
Create one receiving record for each supplier document, SKU, batch and pack quantity. Retain the invoice, delivery note, packing list and relevant transport or import papers. Split records for mixed-batch cases. Show the chain from receipt to location and status, such as available, held, returned, damaged, recalled, destroyed or quarantined. If a case is opened, record the date and quantity moved into sellable packs.
A trade buyer’s files should demonstrate source and movement without reconstructing events from email. Great Britain’s General Product Safety Regulations guidance says distributors should show traceability and retain documents showing from whom they bought goods. It also requires cooperation with enforcement authorities. Where a business knows a supplied product presents an incompatible consumer risk, the guidance says the producer or distributor must notify the relevant authority in writing.
For businesses that manufacture, import, store, move, stamp or supply vaping liquids in the UK, HMRC’s record guidance requires complete, legible, promptly retrievable records and supporting evidence for at least six years. Stock records should cover receipt, holding, operations and despatch, including date, net liquid volume, duty status and location, with an auditable trail to sales, exports, destruction and duty declarations as relevant.
From 1 October 2026, the Vaping Duty Stamps scheme requires vaping products manufactured or imported into the UK to have a duty stamp fixed to final retail packaging. For stock within the scheme, join the SKU, batch and pack record to the stamp-presence check and transaction, rather than keeping disconnected spreadsheets.

Make the file usable when it matters
A usable traceability file is searchable, controlled and ready to export. Set a record owner, control SKU master-data changes and log amendments. Back up electronic records and test readable exports. Periodically confirm staff can retrieve a received batch’s supplier, delivery, quantity, balance, locations, pack split and onward transactions. Investigate and record any difference.
Maintain a documented hold process so staff can search by batch, stop despatch, count stock and identify onward movements. Do not alter or delete the original record during a query; escalate a suspected issue through the business’s compliance process.
Traceability should also support stock segregation. Since 1 June 2025, it has been illegal for businesses to sell, supply, offer to sell or supply, or hold for sale single-use vapes in the UK; leftover stock must be recycled. Defra’s business guidance says to separate that stock, label it unsellable and remove it from the shop floor or online store until collection. Connect disposal or recycling evidence to SKU, batch where available, quantity and date. See what makes a vape reusable in the UK for the current definition.

FAQ
Is a barcode enough for vape traceability?
No. A barcode may help identify a product type, but it does not necessarily distinguish production batches. Retain the batch number shown on the relevant pack and link it to the SKU, supplier documents, receipt and onward movement records.
What should a wholesaler record at the point of sale?
Record the date, customer, SKU, quantity and batch or controlled stock source where your system supports it. HMRC says wholesalers and retailers should keep purchasing and sales records showing supplier, date, SKU, volume and stamp presence on retail packs for duty-paid vaping products.
How long should UK vaping duty documentation be kept?
HMRC states that businesses within scope must retain all records and supporting evidence for at least six years. Keep documents legible and available in a readable form.
