A brand selling one cleanser from one factory has one relationship to manage. A brand with a full range usually ends up with two, three or four, & the reason is rarely a love of complexity. No single plant is equally strong across a fragrance, a pressed powder, a hot-filled emulsion & a filled softgel capsule, so the range gets divided along the lines of capability.
The decision itself is usually sound. The cost of it is usually underestimated. This article sets out why brands split a range, the coordination costs that never appear on a quotation, the parts of a range that should never be divided, & how to hold one sensory & documentary standard across sites that have never met each other.
Why brands split a range across factories
Four reasons cover most of the cases. The first is capability, because the equipment & the process knowledge differ by category, & a plant set up for emulsions is not the plant for a wax-based stick or a filled softgel.
The second is capacity. If one site is booked through the peak months, a brand can either move the launch or place part of the range elsewhere. The third is risk, because a fire, a suspension or a collapse in quality at a single site should not remove the whole range from the market at once.
The fourth is commercial. Some buyers prefer that no single supplier holds the complete formula set, & splitting the range is also a way to keep the negotiating position open at each renewal.
The costs that never appear on a quotation
Each site adds a fixed overhead that no quotation reflects. Sampling is repeated, because a base approved at one plant is not automatically the same base at another. MOQ is paid per site rather than once, so the brand holds more stock in more places.
Artwork & proofing are repeated as well. Pack components bought at two sites rarely come off the same tooling, so a colour match that passed at one plant has to be re-approved at the other, & every later change has to be pushed to both.
Then there is the coordination time. Someone has to keep two production calendars, two document sets & two contact lists aligned, & that person is usually the founder. The cost is invisible on a purchase order & very visible in the diary.
What should never be split
Some parts of a range are judged side by side by the customer, & those belong in one place. A shade family is the clearest case: if three foundation shades are made at two sites, an undertone shift across the range becomes a customer service problem rather than a technical one.
A fragrance family is the second. If a body wash & a body lotion are meant to smell like the same scent, they should be made where the same fragrance compound is dosed in the same way, or at least where both sites buy the identical compound code from the same house.
A paired product & its refill, a product & the pack it fits, & anything sold as a set belong to the same category of risk. Splitting them saves a little on unit cost & creates a mismatch the customer notices immediately.
Holding one sensory reference across sites
The brand should own the reference. Not the factory, not the component supplier, & not a photograph on a phone. A sealed retained sample of the approved batch, stored under the conditions the label claims, is the standard against which every later batch is compared.
The reference has a life of its own, & a sample held for three years is not a fair comparison against a fresh batch. It should therefore be refreshed on a defined cycle, with the refresh recorded against its batch code & date.
At each site a signed golden sample should sit on the bench, & the brand should see the photograph taken under fixed lighting as well as the illumination used for the colour check. Describing a colour in words across two continents is not a control.
Fragrance & colour as the hardest joins
Fragrance travels between sites better than colour does, provided both sites buy the same compound from the same house & dose it identically. The compound code, the supplier & the dosage should be written into both specifications rather than left for each site to source.
Where a fragrance is present, the allergen declaration has to travel with it. The IFRA certificate & the allergen statement belong to the compound, so both sites have to use the same version for the labels to stay consistent across the range. A flash point statement is also needed wherever the product ships as a flammable liquid.
Colour is the harder join because it depends on the substrate, the pigment lot & the lighting. A shared pigment source removes one variable, & an instrument reading with an agreed tolerance removes the argument about whether two batches match. Neither removes the need for a person to look at both under the same lamp.
Keeping documentation consistent across sites
Two sites will produce two document sets in two formats unless the brand imposes one. The specification sheet, the certificate of analysis, the batch record & the stability summary should follow a single template that the brand owns & issues to both.
A master list is what makes that work. One register naming every SKU, its site, its formula version, its specification version & its current artwork version is enough to stop a label going to press with a superseded claim on it.
The claim file should also sit centrally with the brand. Where two sites each assemble their own evidence, the wording that reaches a marketplace listing is whichever file someone happened to upload, & that is not a system.
Sequencing orders when capacity collides
Splitting a range does not remove the peak. If both sites are busy in the same months, two purchase orders with overlapping delivery dates will compete for the same freight, the same testing lab & sometimes the same component supplier.
The practical fix is to stagger the range. Launch the category that carries the campaign first, & let the supporting SKUs follow a few weeks behind, so that the cash & the attention are not demanded at the same moment.
Where two sites genuinely have to deliver on the same date, the earlier order should be the one with the longer route or the tighter quality hold. Booking both slots at the start of the season is far cheaper than chasing them once the peak has begun.
Who owns the master specification
The master specification belongs to the brand in every case. A factory that holds the only copy of the formula & the only specification controls the relationship, whether or not the contract says so.
Version control is what makes ownership real. A specification without a version number & a date cannot be referenced reliably, & a change agreed verbally at one site will not reach the other.
A short change note, circulated to every site whenever a specification moves, is the cheapest control in the whole arrangement. It is also the one most often skipped, usually because the change looked small at the time.
When one site starts to fail
Failure rarely arrives as a single event. It shows first as small things: a certificate that arrives late, a deviation that is explained but never documented, a batch released with a limit quietly widened.
The brand needs an escalation ladder agreed in advance. Who is told, at what threshold, & what happens to the stock already in transit. A hold placed on a batch is only useful if there is a defined route back to release.
A second site is not a working back-up unless it holds a valid approved sample, a current specification & a slot it can actually run. A back-up that would need six weeks of development before it could produce anything is a name on a list rather than a plan.
Tooling, moulds & intellectual property
Where a custom shape, a mould or a bespoke component is involved, the question of who owns it should be settled before the tool is cut. Ownership recorded after the fact is expensive to establish.
The formula & the artwork are the same kind of asset. A mutual confidentiality agreement at the start, a clear statement of which party holds the formulation, & an agreed rule on whether a supplier may produce a similar product for another brand are the three clauses that matter.
Tooling also has a physical location. If a mould sits at a site the brand no longer uses, recovering it requires a written right to collect it rather than a friendly conversation.
What to centralise & what to keep local
The table below sets out the decisions a brand faces when a range runs across more than one factory, where each decision should sit, why, & what goes wrong when it drifts.
| Decision | Where it should sit | Why | What goes wrong if it drifts |
|---|---|---|---|
| Master specification & version control | Brand | One source of truth across sites | Two sites produce to different limits |
| Fragrance compound sourcing | Brand or a nominated house | Same compound, same dosage | Scent drifts between formats |
| Pigment source for a shade family | Brand | Removes one variable in colour | Undertone mismatch inside the range |
| Certificate of analysis format | A common template | Results stay comparable across sites | Batches cannot be compared at all |
| Claim file & supporting evidence | Brand | One approved wording per claim | A listing carries unapproved wording |
| Production slot booking | Each site, coordinated by the brand | Sites know their own capacity | Two orders collide in the peak |
| Retained master sample | Brand, with a bench copy per site | Fair comparison over time | Comparison against an aged sample |
| Tooling ownership record | Brand, in writing | The asset stays recoverable | A mould stranded at an old site |
The split above is a starting position rather than a fixed rule. Where a brand has no quality function of its own, some of these sit more naturally with a lead site, & whichever way it is arranged the position should be written down rather than assumed.
What to put in the brief
Say at the start how many sites will be involved & which SKUs sit where, because a factory that knows it is making part of a range will design its controls differently from one that believes it is making the whole thing. Name the specification owner inside the brand, & confirm the version numbering convention that every site will follow.
- The SKUs assigned to this site, & the SKUs that sit elsewhere.
- The products that must stay together, such as a shade family, a scent family or a paired set.
- The fragrance or pigment source, & whether it is nominated rather than chosen locally.
- The master specification & its version, & the person who issues it.
- The certificate of analysis template that all sites will use.
- Who holds the retained master sample, & how often the reference is refreshed.
- The escalation ladder, including who places a hold & who releases it.
- The tooling, formulation & artwork ownership position, in writing.
Then keep the arrangement reviewed rather than merely agreed. A short annual reconciliation, listing each SKU with its site, its specification version & its current artwork, is enough to catch the drift that accumulates quietly between launches.
Where our capability fits
We are used to producing part of a range rather than the whole of it, so the specification we work to is the brand's master version rather than our own house standard. Where a brand is splitting a family across sites, we will say which join is likely to show first & what reference we need in order to hold our end of it.
We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, with documentation aligned to the brand's master set. Our lines include a facial essence capsule range, a fragrance range & a firming face cream, each supplied with the certificates & declarations a second site would need.
Tell us how the range is divided & which SKUs we would hold, & we will come back with the specification, the reference standard & the documentation handover. Start at our inquiry page, email capsulebiotech@163.com, or message the right team on WhatsApp: Capsule Series (capsules only) +86 158-7655-5319, Cosmetics Series (serum, hair care, body care, fragrance) +86 158-7655-5319. What a site visit should cover is set out in our supplier audit checklist, & the fragrance documents in our guide to fragrance compliance.
General manufacturing information, not regulatory or legal advice. Contract terms, ownership of tooling & formulations, & labelling duties vary by market & by agreement, & the applicable position should be confirmed before a product is placed on sale.
