Yes — some cosmetic manufacturers arrange testing and certification for you, but most don't. A full-service formulation studio will organise stability, microbiological and preservative efficacy testing, prepare your compliance documentation for New Zealand, Australia, the EU and the US, and guide you through cruelty-free, vegan and organic certification. Contract fillers usually won't.
This is an expensive assumption to get wrong. You approve a sample, then somebody asks for your safety documentation — and you discover testing was never included, the lab lead time is eight weeks, and your launch date has moved. Here's what testing and certification actually involve in New Zealand and Australia, and how to tell before you sign whether your manufacturer will handle it.
What testing does a cosmetic product actually need before launch?
There's no single "cosmetic test." There's a panel, and which parts you need depends on the product type, the packaging and the claims you want to make.
- Accelerated stability testing. Typically 12 weeks at 40°C, with parallel samples at 4°C, 25°C and in light. It tells you whether the emulsion separates, the colour shifts, the pH drifts or the fragrance turns. Twelve weeks at 40°C is used as an indicator of roughly one to two years of shelf life — it's a predictor, not a guarantee, which is why real-time testing runs alongside it.
- Preservative efficacy testing (challenge test). Usually run to ISO 11930. The lab deliberately inoculates your product with bacteria, yeast and mould and measures whether your preservative system kills them. Any water-containing product needs this. Skipping it is how brands end up with a recall.
- Microbiological testing on the finished batch. Total viable counts and screening for specified organisms, against the limits in ISO 17516.
- Packaging compatibility. Your formula in the actual jar, pump or tube it will ship in — not a lab beaker. Essential oils and certain actives can soften plastics or clog pumps.
- Safety assessment. A qualified assessor reviews the formula, concentrations and exposure to confirm the product is safe as designed. This becomes your Cosmetic Product Safety Report (CPSR) for the EU and UK.
- Claims substantiation. "Hydrates for 24 hours" or "reduces the appearance of fine lines" needs in-vivo or instrumental data behind it. Optional — until a regulator or a competitor asks.
Do New Zealand and Australia legally require testing?
Neither country pre-approves cosmetic products the way a medicine is approved, but both put the responsibility for safety squarely on you.
New Zealand regulates cosmetics through the EPA's Cosmetic Products Group Standard. Updated rules took effect on 1 January 2026 — scope now extends to non-hazardous cosmetics containing a hazardous substance, the prohibited and restricted ingredient schedules have changed, and PFAS ingredients are being phased out. Products caught by the standard need a current Safety Data Sheet and, where applicable, HSNO approval before import or manufacture.
Australia runs through AICIS. If you import or manufacture cosmetics there, you must register — there is no volume threshold, so a 100-unit launch counts. The registration year runs 1 September to 31 August, with an annual declaration due 30 November, and every ingredient introduction has to be categorised. Labelling follows the Consumer Goods (Cosmetics) Information Standard, and the moment your claims stray into therapeutic territory you're in TGA jurisdiction.
Neither regime hands you a list saying "run these five tests." But a safety assessment without stability and challenge test data behind it isn't a defensible one — which is why the panel is effectively mandatory in practice.
Which certifications are worth paying for?
Certification is different from compliance. Compliance is the legal floor. Certification is a third-party badge you choose to buy because your customer looks for it.
- Cruelty-free (Leaping Bunny / Cruelty Free International). Requires a supply-chain audit and supplier declarations. Most of the work is documentation, not reformulation.
- Vegan. Straightforward if the formula was designed vegan from the start. Retrofitting is where it gets expensive — beeswax, lanolin and carmine are the usual culprits.
- Organic (BioGro NZ, ACO, COSMOS via ECOCERT or Soil Association). The most demanding. Organic standards constrain your preservatives, emulsifiers and processing, so the formula has to be built to the standard from day one. Deciding to go organic afterwards usually means starting again.
- Halal. Relevant for Southeast Asian and Middle Eastern export. Scope it early — it affects alcohol and raw material sourcing.
Our honest view: certify what your customer actually asks about. Most indie brands are better served putting that budget into claims substantiation than into a badge nobody in their audience is looking for.
How does The INCI Lab handle testing and certification?
Testing and compliance are built into our pathways rather than bolted on afterwards. Stage four of the Pathfinder Framework — IP and Compliance — is where we coordinate lab testing, prepare documentation and transfer the formula to you.
In practice:
- We brief and manage the external labs, so you're not chasing quotes and sample shipments.
- We prepare compliance documentation for New Zealand, Australia, the EU and the US, including AICIS-ready ingredient information.
- You get full IP transfer before manufacturing on The Visionary pathway, so the test data and formula belong to your brand — not to a lab that can resell it.
- Minimum order quantities start at 100–500 units, so you can test a market without funding a 5,000-unit run.
- We formulate cruelty-free, vegan and fragrance-free as standard, with organic and BioGro capability where the brief calls for it.
Timelines are honest: The Accelerator runs 4–6 months from around $2,000, The Visionary 9–12 months from around $4,000. Testing sits inside those windows — the 12-week stability run is a real constraint nobody can compress. If you already have a formula and just need it assessed, Ask The Chemist is a 30-minute consult from $150. Our Ready-to-Go bases are already stability-tested, which removes most of that timeline entirely.
Frequently asked questions
Do I need testing if I'm only selling at markets or online in small quantities?
Yes. Neither the New Zealand Group Standard nor AICIS registration has a volume threshold. Selling 50 units carries the same safety obligations as selling 50,000.
How long does cosmetic testing take?
Accelerated stability is 12 weeks and can't be shortened. Preservative efficacy testing runs 28 days. Both can run in parallel, so budget around three to four months from final formula to test-complete, plus lab queue time.
Can I sell in Australia if my product is made in New Zealand?
Yes, but you or your Australian importer must be registered with AICIS and your labelling has to meet the Australian information standard. New Zealand compliance doesn't automatically satisfy Australian introduction obligations.
What's the difference between a safety assessment and a CPSR?
A safety assessment is the underlying technical review. A CPSR is the formal document format required under EU Regulation 1223/2009. Selling into the EU also requires an EU-based Responsible Person and a CPNP notification.
Who owns the test data — me or the manufacturer?
It depends entirely on your contract. On The Visionary pathway you receive full IP, including the formula and its data. Many private label arrangements keep both with the manufacturer, so you can't take the product elsewhere. Ask before you sign.
Where to start
If you don't know which tests apply to your product, that's a 30-minute conversation, not a research project. Get in touch and we'll tell you plainly what your product needs, what it doesn't, and roughly what it costs.
Regulatory requirements change. The details above reflect the New Zealand and Australian rules as at August 2026 — always confirm current obligations with the EPA and AICIS before launch.
