A fan brand selling table, pedestal, wall and ventilation fans often buys them from three or four different factories. Each one made sense when it was added. Together they create a supply chain with more trucks, more follow-up and more ways for a season to go wrong than the range needs. This note looks at what changes when one OEM makes the whole range, and where that approach has limits.
Where the complexity comes from
Every additional supplier adds its own purchase orders, its own production schedule, its own quality system, its own part-load shipments and its own interpretation of your colours and carton artwork. None of these is a large problem on its own. Multiplied across four vendors and a short selling season, they become the reason stock arrives late or arrives mismatched.
One truck instead of three
When the range comes from one plant, shipments consolidate. For one legacy Indian brand, moving the range to a single source cut total landed cost by 4–5%, simply because the trucks went out full instead of carrying part-loads from separate suppliers. That saving does not need renegotiating each year; it comes from how the goods move. Details are in our peak-season supply case study.
One set of colours
A pedestal fan and a wall fan from different factories rarely match, even when both were briefed with the same colour reference. Plastics from different moulders, on different masterbatches, drift. When every plastic part of every fan in the range comes off the same moulding machines, the range looks like one family on the shelf. We mould on twelve machines from 80T to 220T and make our own guards, which is what lets us hold colour across the whole range. Our colour-matched range case study explains why white is the hardest colour of all.
One quality system and one point of accountability
With several suppliers, a field complaint starts with working out which factory made the fan. With one, the conversation starts with the fix. One inspection regime, one set of test records and one team to call also makes it easier to move to lighter-touch inspection over time; one large Indian brand has moved us to self-inspection on the strength of that record.
One capacity plan for the season
Peak season is when multi-vendor supply hurts most, because each supplier allocates its own capacity to its own priorities. With one supplier covering the range, a single pre-booking (we ask for about 45 days ahead of the season) secures table, pedestal, wall and ventilation fans together, and the mix can be adjusted inside one plan as early sales data comes in.
The honest limit: concentration risk
Putting the whole range with one manufacturer concentrates risk as well as simplifying supply. If that plant has a problem, every category is affected at once. Brands manage this in different ways: keeping a qualified second source for their highest-volume model, agreeing a written capacity commitment for peak months, or splitting by market rather than by product. A single-source arrangement works best when the supplier is open about capacity, has the range in-house rather than subcontracted, and has a track record of telling you about problems before you find them.
Questions to ask a single-source supplier
- Which of the range is made in-house, and which is subcontracted?
- How is capacity allocated across categories in peak months?
- Can models be mixed in one shipment to fill trucks and containers?
- How are colours controlled across different products?
- What happens to your orders if one line goes down?
