Most first-year brands plan launches by readiness: the product ships when the sample is approved, the pack arrives & the label is right. Retailers, marketplaces & gift buyers do not plan that way. They plan in windows, & a window that closes does not reopen until the same point next year. A seasonal calendar exists to make sure the readiness date lands inside the window rather than beside it.
This article sets out how a year of launches is actually built from the factory side: the windows buyers work to, how to count backwards from a shelf date, which lead times move & which are fixed, how peak season consumes capacity, what the factory calendar does to a February plan, how four launches divide the same cash, plus how to decide what to repeat & what to retire. It closes with the brief items that make a seasonal plan quotable.
Why a calendar beats a launch-when-ready plan
A product launched outside its window does not fail immediately. It fails slowly, because it arrives when nobody is looking for it, spends its first months without a reason to be bought, & consumes shelf life while it waits. A firming face cream released in November competes for attention with every gifting promotion on the channel. The same product released in late winter has a clear run.
A calendar also fixes the internal sequence. Once the shelf date is known, sampling, stability, artwork, printing, production, freight & notification all have deadlines that can be checked rather than estimated. Without a date, every stage takes as long as it takes, & the launch drifts a month at a time until the season has passed.
The counter-argument is real: a calendar can push a product out before it is ready. The answer is not to abandon the calendar but to separate the two decisions. The product is ready when the evidence supports it. The launch window is a commercial choice. If the evidence & the window conflict, the window moves to the next one, & the plan is updated deliberately rather than by drift.
The windows buyers actually work to
Four windows carry most of the beauty year. Late winter into early spring is the renewal window, when customers replace what they used through the cold months & skincare gets attention after a season indoors. Late spring into early summer is the light-format window, when lighter textures, mists & travel sizes move. Late summer into early autumn is the routine-reset window, when heavier textures return & body care picks up. The final quarter is the gifting window, which behaves differently from the other three because the buyer is often not the user.
Each window suits a different product. Gifting supports sets, capsules, novel shapes & fragrance, where presentation carries weight. The renewal window supports the staple hero, because the purchase is a replacement rather than a discovery. The light-format window supports travel sizes & single-dose formats, because portability is the benefit. The reset window supports body & hair care, where a larger fill is an advantage.
The mistake is to read all four as equal. A small brand with limited cash should not attempt four launches. Two well-timed launches in the two windows that match the range beat four launches that each arrive slightly late & slightly underfunded.
Working backwards from a shelf date
Counting backwards is mechanical once the stages are listed. From the shelf date, subtract the freight leg, the packing days, the production days, the quality release, the print & pack lead time, the artwork approval, the sample approval, the sampling round itself, & the stability window the formula needs. What remains is the date by which the brief has to be issued.
Two stages move the answer most. Stability is the least compressible, because a real-time study takes the time it takes, & accelerated data may support a shorter claim rather than the claim the brand wanted. Pack lead time is the most commonly underestimated, because a custom mould or a printed bottle is not a stock item & cannot be pulled forward with money once the schedule has slipped.
There is a version of this exercise worth doing for every SKU separately rather than for the launch as a whole. A range launched on one date usually needs its most complex product started first, even if that product appears last in the marketing sequence. The simple products can be sampled later without holding the date.
Lead times that move, plus the ones that do not
Sampling is the most elastic stage. A revision to texture or scent can be turned around quickly where the base already exists, & slowly where the change touches the emulsifier pair or the preservation system. Two sample rounds is a reasonable assumption; three is a warning that the brief was not specific enough.
Packaging is the least elastic. Board, glass, pump & cap suppliers run their own schedules, & a decorative finish such as hot foil or a soft-touch coating adds a separate pass through a printing line. Where the pack is imported, a port delay lands directly on the launch date. The reason to lock the pack before the formula is final is that the pack is the item that cannot be recovered if it is late.
Fragrance sits in between. A compound can be matched quickly from an existing library; a new accord built to a brief takes longer, & needs its own documentation. Each compound arrives with an IFRA certificate & an allergen declaration covering the 26 allergens that several markets require to be declared above an applicable threshold, so a late fragrance change is also a late labelling change.
Booking capacity around peak season
Filling lines, packing tables & quality control time are shared across every brand the factory serves. In the weeks before a major selling season, those resources are committed, & a brand that books late is offered a slot after the peak or a partial run. Capacity planning is therefore part of seasonal planning, not a separate operational topic.
The usual advice is to book earlier than feels necessary. A slot held for a date two months out costs nothing; a slot that does not exist in six weeks costs the season. Where the calendar is tight, ask which stages can be run separately, since bulk production, filling & packing can sometimes be split so that only the final stage competes for the busiest resource.
Booking early also changes the cash profile, because deposits fall earlier. A brand planning two waves should map the deposit dates next to the expected revenue dates, so that a payment does not land in the same week as a marketplace settlement delay.
The factory calendar plus holiday shutdowns
The manufacturing year is not twelve even months. Most production in Asia stops for a period around the lunar new year, when the workforce travels & plants close for one to three weeks, with a slower ramp-up afterwards while staff return & lines are restarted. Orders that need to ship before that period must be produced & packed considerably earlier than the shutdown itself.
The same applies to other public holidays & to the summer peak in some regions, where power usage restrictions can affect plant schedules. None of this is hidden, but it is only visible to a buyer who asks for the production calendar at the planning stage rather than at the booking stage.
The practical effect on a seasonal plan is that the first quarter is the tightest period of the year. A brand aiming at a spring window needs its brief issued the previous autumn if the goods are to ship from Asia with any margin for a rework.
Cash across four launches
Four launches in a year means four deposits, four pack orders, four production balances & four freight payments, all of which land before their revenue does. Spread across twelve months, that is manageable for a brand with steady sales. Concentrated into two quarters, it is the most common reason a good calendar collapses.
The way to hold a calendar without holding four separate cash peaks is to share. A shared base across several seasonal SKUs means one development project rather than four. A shared carton size or closure means one print booking rather than four. A single hero product with two seasonal variants is usually a better commercial proposition than four unrelated products, even if the four look better in a planning document.
Payment structure matters as much as total cost. A schedule that puts a large deposit early & the balance on shipment is harder on cash than one that pays in three instalments tied to milestones. Agreeing the structure at the quotation stage is easier than renegotiating it once the artwork has been approved.
What to repeat, plus what to retire
Seasonal planning has a second half that brands skip: deciding what not to bring back. A SKU kept for another year keeps its minimums, its artwork, its stability programme & its stock risk. A SKU that sold steadily but slowly is usually costing more in complexity than it earns in contribution.
The decision is easier when the data is separated. Look at repeat purchase rather than first purchase, at full-price sales rather than discounted sales, & at returns rather than revenue. A product with low volume, high repeat & low returns is worth keeping. A product with high first-purchase volume, low repeat & a high return rate is a seasonal experiment that has already delivered its answer.
A manageable rhythm for a young brand is one new SKU & one revised SKU per year, with the rest of the range held steady. Reformulation, pack refresh or a new size can carry a season without adding a new item to the catalogue, & a refreshed product usually sells better than an unfamiliar one.
Regional seasonality across markets
A calendar built for one market does not travel unchanged. The southern hemisphere inverts the texture logic, so a body lotion promoted for winter in Europe is a summer product in Australia. The Gulf markets put the heaviest demand in the cooler months & make the summer months a genuine logistics problem, because heat in transit affects meltable formats such as balms, sticks & butters.
Gifting occasions are regional rather than universal. The final quarter dominates in Europe & North America, while the Ramadan & Eid period drives a separate gifting season in the Gulf & parts of Southeast Asia, & the lunar new year drives another in East Asia. A set designed for one occasion can be adapted to another with a change of outer carton rather than a change of contents.
Where a product contains a meaningful amount of alcohol, regional rules & carrier limits interact with the season as well. A fragrance or mist in a summer shipment faces flash point declarations, limited quantity marking & air freight restrictions, so the transport mode may decide the window more than the marketing plan does.
Seasonal launch calendar
The table below sets out the four windows against the decisions that belong to each one. It is a planning aid rather than a fixed timetable: the windows shift with the category, the hemisphere & the channel, & a body care range will not use them the way a colour cosmetics range does.
| Window | What sells in it | Brief issued by | What goes wrong |
|---|---|---|---|
| Late winter, renewal | Staple hero, replacement packs, refills | The previous autumn | Briefing too late for stability, so the claim shrinks |
| Late spring, light formats | Mists, essences, travel sizes, capsules | Early in the same year | Small fills filled inaccurately under time pressure |
| Late summer, routine reset | Body & hair care, heavier textures | Late spring | Competing for the busiest filling slots of the year |
| Final quarter, gifting | Sets, capsule cards, fragrance, novelty shapes | The spring before | Secondary pack minimum exceeding the whole budget |
| Lunar new year period | Whatever has to ship before the shutdown | Well before the winter | Booking production inside the closure window |
| Gulf cooler months | Body care, oils, richer textures | Several months ahead | Meltable formats shipped through summer heat |
| Southern hemisphere winter | The inverse of the northern texture logic | Offset from the northern plan | Reusing northern artwork with the wrong season language |
| Any window with alcohol in the set | Fragrance, mists, sprays | Earlier than the rest | Air freight restrictions discovered after booking |
Read the calendar as a relative guide rather than a fixed schedule. Lead times, shutdown dates, carrier rules & demand patterns all differ by category & by destination, so the planning conversation should confirm each assumption rather than inherit it.
What to put in the brief
Give the factory the calendar, not only the product. A brief that states the shelf date, the market & the channel lets the plant propose a sequence that fits, & it lets the plant tell you early if the date cannot be met. A brief that states only the product will be quoted accurately & scheduled optimistically.
- The window each SKU is aimed at, & the shelf date that matters commercially.
- The markets, since notification & labelling timing differs by destination.
- The channels: own store, marketplace, wholesale or gifting.
- Which SKUs share a base, a fragrance family or a pack element.
- The quantity you can pay for in each wave, rather than for the year as a whole.
- Whether any product contains alcohol or a fragrance requiring extra transport documents.
- The claim wording you plan to use, so stability & testing needs are known early.
- The production calendar you are working to, including any shutdown period in your plan.
Then diarise the plan rather than leaving it in a document. A calendar with dates against sampling, artwork, production booking & freight is a working tool; a calendar with only launch dates is a wish list. Where a stage slips, the plan should show which downstream dates have to move with it.
Where our capability fits
We plan production against a brand's calendar rather than against our own convenience, which means telling a buyer early when a date is not achievable & proposing the nearest workable window instead. We share the production calendar with brands at the briefing stage, including shutdown periods, so that a seasonal plan is built on the real year rather than an idealised one.
We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & seasonal variants can be built as line extensions of an existing base rather than as new projects. Our lines include a vitamin C face cream, hair care essential oil capsules & a chamomile toner mist, which between them suit the heavier, the capsule & the light-format windows.
Tell us the windows you are aiming at, the markets & the money available in each wave, & we will come back with a sequence, the stages that set the dates & the point at which the brief has to be issued.

How launch timing interacts with demand cycles is covered in our article on trend cycles, & how slots are secured in our guide to capacity planning.
General manufacturing information, not regulatory or legal advice. Lead times, shutdown periods, notification timelines, labelling rules & transport restrictions vary by product, pack, season & destination, & the applicable requirements should be confirmed for each market before a product is placed on sale.
