Change vape hardware supplier without restarting compliance

The principle, in one sentence

Your documentation describes the product as you sell it, so a changed part means a changed description. That is the whole idea, and everything practical follows from it.

It cuts both ways, which is the useful part. Because the file describes a product rather than a supplier, changing supplier is not automatically a compliance event. A carton printed by a different printer to the same artwork changes nothing. A cell from a different manufacturer changes the evidence you hold about the cell. So the question is never "do I need a new file", it is "which parts of the file describe the thing that changed". Answer that part by part and the job is usually smaller than it looked.

What a changed part touches

Work down this table with your own product in front of you. The right-hand column is a question rather than an instruction, because what has to be redone depends on your product, your market and which instruments apply to it.

Hardware changes and what each one reaches in your documentation

What changed	What in your documentation describes it	The question to answer before you switch
The cell	Battery documentation, transport documentation, the safety assessment, anything printed about capacity or charging	Does every battery document you hold name the new cell, or the old one
The board or its firmware	Electrical test evidence, the instructions, anything describing modes, cut-offs or indicators	Has any behaviour the customer sees or the tests measured changed
The charging port	Electrical evidence, accessories supplied, packaging and instructions	Does the pack still describe the port fitted
Housing material	Material declarations, substance evidence, the recycling and marking information	Do you hold declarations for the new material or only the old
Any part in the air path	Material declarations per part, and any material testing you commissioned	Which parts moved, and do the declarations name them individually
The heating core or element	Specification, electrical evidence, any performance claim you publish	Does the resistance or the construction differ from what you tested
Thread or mechanical dimensions only	Specification, compatibility claims, packaging fit	Do your compatibility statements and your tray still hold
Mouthpiece fitting method	Specification, assembly and capping instructions, closure claims	Has anything you say about the closure stopped being true
Retail packaging or insert	Artwork, printed information, any certified closure	Is a certified feature involved, and is the certificate for this pack
Marking or logo only	Artwork files and the marking drawing	Is the required marking still legible and in the right place
A new factory, same drawing	Audit records, lot marking scheme, the supplier side of your quality records	Whose evidence do you hold, the drawing owner's or the new plant's

Two rows deserve emphasis. Firmware is the change most often missed, because nothing about the object looks different. And the same drawing built in a different plant is a different production origin, so the audit and lot records behind it are not the ones you already have. See factory audits.

What does not change

Plenty, and it is worth naming so the exercise stays proportionate. Your company, your role in the supply chain, your producer registrations, your brand and your customer contracts are all yours and unaffected by who made the part.

The instruments that apply to your product also do not change simply because the supplier did. If RoHS and REACH applied to your product last month they apply to it this month; what changes is whose evidence you are relying on to satisfy them. The same holds for the EU Battery Regulation and for WEEE, and for your obligations as the party placing the product on the market under the General Product Safety Regulation. Our compliance guides cover each of those separately: CE marking, RoHS and REACH, the Battery Regulation, WEEE registration and the GPSR responsible person.

One thing you should not do is overwrite. The units already sold are described by the documentation current when they were made, so keep the old set attached to the batches it describes and start a new set for the new part. A file edited in place can no longer tell you which product a complaint belongs to.

The drop-in replacement trap

Two cartridges quoted to the same nominal specification are not interchangeable, and the reason is not usually quality. A specification is a summary. Overall length, shoulder position, thread tolerance, intake count and mouthpiece height can all differ inside a description that reads identically, and the things that break first are your tray, your carton and your filler's fixtures. That is a tooling and artwork cost arriving after the price comparison was signed off, and it is invisible on a quotation.

The evidence is the second trap. Like-for-like describes the numbers, not the paperwork. Your test reports and declarations name the part you tested, so a part with the same numbers from a different maker is still a part you hold no evidence for. Treat it as new and decide what has to be repeated.

Reasons to switch that hold up

• Single-source risk. The strongest reason, and the one most often left until the incumbent fails. A qualified second source you never order from is cheap insurance.
• Documentation quality. A supplier who cannot produce declarations naming your SKU has quoted an incomplete price. See supplier documentation.
• Lead time or minimum order quantity. Both are structural and hard to negotiate away with an incumbent who has already set them.
• A defect rate you have measured from your own incoming inspection, over more than one delivery.
• Unit price, last. The easiest number to compare and the one most likely to be reversed by tooling, artwork and re-testing you did not budget for.

How to switch, in order

1. Inventory what you hold. Every document, which SKU and revision it names, and its date. Most of the work in a switch is discovering this list was never complete.
2. Ask the candidate for the same list before you order anything, naming the specific SKU rather than a family.
3. Compare part by part, not supplier by supplier. Use the table above, mark each row unchanged, changed or unknown, and treat unknown as changed.
4. Sample from production, not from a sample room. Measure the dimensions your packaging and your filler depend on, and run the same tests you ran on the incumbent. See hardware sampling.
5. Qualify in parallel, do not swap in one step, so that a problem appears while you still have stock of something that works.
6. Update the documentation before you sell, not after. Anything printed, anything declared and anything you publish.
7. Fix change control on day one. No revision reaches you without notice, and none reaches your filler without passing through you. See working with a filler.

What this page does not tell you

It gives you no retention periods, no article numbers and no notification duties. Those depend on which instruments apply to your product and on the market you sell into, and they belong in the primary text or with an adviser rather than in a supplier's guide. The instruments are linked above and again below.

What we can tell you is the hardware side. Stock 510 cartridges and the rest of the range ship with specifications, and CE, RoHS, REACH, Battery Regulation and WEEE documentation is available on request, naming the SKU rather than a family. The market registrations stay with whoever places the finished product on the market. See compliance.

Frequently Asked Questions

Does changing hardware supplier mean starting compliance again?

Not usually, and not never either. Your documentation describes a product, not a supplier, so the question is which parts of that description the change touched. A new source for an identical printed carton touches almost nothing. A different cell, a different board or a different material in the air path touches the evidence you hold for those things. Work part by part rather than treating the switch as one event.

Can I second-source a like-for-like cartridge without updating anything?

No. Like-for-like describes the specification, not the evidence. Two cartridges built to the same nominal figures are still two different products made on two different lines, and the test reports and declarations you hold name the one you tested. Treat a second source as a new part that happens to have familiar numbers, then decide what has to be redone.

What should I ask a new hardware supplier for before I move?

The same document set you already hold for the incumbent, naming the specific SKU rather than a product family, plus the specification sheet with tolerances, the lot marking scheme and their change control policy. Compare the two sets side by side before you compare prices. A supplier whose documentation is thinner than your current one is a cost, not a saving.
