Demand moments, described qualitatively
This note does not quote seasonal percentages, because published breakdowns vary by country, channel and product and no single figure applies to every importer. What can be said is the shape of the year. Three moments recur in most markets: the gift season at the end of the year, when appliances are bought as presents and retailers run promotions; spring cleaning, when households refresh their home care routines and compare new machines; and back-to-school or student-move periods, when compact, low-cost and easy-to-store machines, such as handhelds and small sticks, are bought for rooms and flats. Local events add to these: national shopping days, tax-refund periods, moving seasons and holidays all move demand in particular countries.
The pattern differs by line. Robots and premium sticks tend to follow the gift and promotion calendar. Handhelds and car vacuums link to travel and to vehicle care in warmer months. Commercial machines follow the budgeting cycle of hotels, offices and cleaning contractors, with spring refurbishment before the high season for hotels. Pet hair machines follow shedding seasons in some regions. The importer's own sales history is the best guide, and the market overview in the vacuum market note helps with segment direction only.
Working backwards from the shelf date
Planning is easier when the question is turned around: given the date by which stock must be on the shelf or in the marketplace warehouse, when must the order be placed? The sequence has five steps, each with a reference time. These are references confirmed in writing for each program.
| Step | Reference time | Note |
|---|---|---|
| Sampling and approval | Public mould 7-15 working days; private label about 15-25 days; ODM engineering samples about 45-90 days | Skipped for repeat orders of an approved model |
| Production | Public mould about 30-45 days; private label about 35-50 days; ODM first order about 60-120 days including certification | Busy periods before holidays can stretch the plant queue |
| Pre-shipment inspection | Arranged before loading | Allow time to rework if the inspection fails |
| Sea freight | FCL to the US west coast about 15-25 days; to Europe about 30-45 days | Port congestion and holidays add variability |
| Customs, delivery and receiving | Depends on market and warehouse | Marketplace warehouse slots may be booked ahead |
Adding the reference times for a private-label cordless stick bound for Europe gives something like 35-50 days of production, a short inspection window, 30-45 days at sea and a few days for clearance and delivery. The order therefore has to be placed in the early part of the year or the summer for a year-end shelf date, not in the autumn. For an ODM first order with new tooling, the schedule is longer still, and certification time should be built in from the start.
Lithium and air freight as a safety valve
When a season is missed, air freight is the tempting answer, but cordless machines carry lithium batteries, and air freight needs UN 38.3 documents, a safety data sheet and compliance with IATA rules. Mains-powered machines are simpler but bulky, so air freight is costly per unit; plan it only for small quantities of high-value or fast-moving lines. Samples and small test lots usually go by express courier in about 3-7 days. For routine volume, the sea route should be the plan, with air as an occasional exception. See logistics and shipping for the routes.
Stock policy by channel
- Retail chains buy against planograms and promotions. They need firm delivery dates, packaging that meets their pallet and label rules, and spare parts. See the retail chain page.
- E-commerce sellers deal with warehouse inbound windows and storage fees that rise at peak. Smaller, more frequent orders reduce stock risk, but each order carries its own minimum, so the plan has to balance the two. See the e-commerce sellers page.
- Brand owners that sell through several channels need one stock plan covering all of them, with parts reserved for after-sales. See the brand owner page.
Risks that planning should cover
Three risks recur. The first is plant capacity: factories fill their schedules ahead of the holiday periods, including the Chinese New Year closure, so a late order may wait or be shifted. The second is variability at sea, which affects the arrival date more than the departure date. The third is demand risk: a promotion that fails leaves stock that costs storage and ties up cash. To manage them, keep a buffer between the arrival date and the date the stock is actually needed, split large orders into two shipments where the minimum allows it, and avoid ordering a seasonal line that cannot be sold outside its season in volume. Perennial lines, such as filters, bags and brush rolls, make a good base load because their demand is steadier.
Splitting orders and holding the base load
One large order feels efficient, but it concentrates risk: a delay, a failed inspection or a weak promotion affects the whole quantity. Splitting the plan into a first shipment for the early part of the season and a second for the replenishment gives room to adjust. The trade-off is that each model has its own minimum, so splitting works best when a model is on a public-mould platform where minimums are lower, typically 200-500 units per model, and less well for ODM projects with tooling cost. Where the brand has several colours or variants, consider holding the common body in one quantity and varying the colour, packaging or accessories at the end of the line, if the plant can do this. Ask the desk early whether a split is realistic for the plant in question.
The base load matters too. Parts, accessories and slow-moving models can be planned on a steady rhythm, for example one container of mixed lines at regular intervals, while seasonal models are handled as projects with their own dates. This mixed approach keeps the plant relationship active through the year, which helps when a late request needs a favour, and it keeps warehouse use more even. A written annual plan shared with the plant, even if indicative, helps it reserve materials such as cells, motors and filter media, which are the items most likely to be short in a busy quarter.
A calendar method
- Mark the dates when each line must be on the shelf or in the warehouse.
- Subtract the delivery and receiving time, then the sea freight time, then the inspection window.
- Subtract the production time for the type of project, public mould, private label or ODM.
- Subtract the sample and approval time for new models, and certification time for first orders.
- Add a buffer for holidays and congestion, and place the order by the resulting date.
- Send the plan to the desk via the quote form to check the plant schedule against the dates.
