When the factory moulds its own packaging: what changes for a buyer
Most cosmetics plants buy their packaging. Those that make it themselves give a buyer two things: shorter lead times and a lower minimum. But not always, and not for everything.
A cosmetics factory and a packaging maker are usually different companies. The factory produces the bulk and fills it into something bought from an outside supplier. Some Korean operations are arranged differently: bottle and cap moulding and box production sit inside the group. For a buyer that is not an organisational detail but several practical consequences.
What changes in lead time
The wait in someone else's queue disappears. When bottles are moulded by an outside supplier, your order joins that supplier's schedule, and the factory cannot influence it.
A change stops being a catastrophe. If you decide to swap the cap mid-project, inside a group that is a conversation between two workshops rather than a fresh order with a new supplier and a new lead time.
But in-house does not mean instant. Tooling still has to be made, moulding still has to be scheduled, and an honest manufacturer will give you those dates.
What changes in the minimum
This is the main one. The minimum on an order is most often set not by the bulk but by the packaging, and it rests on the minimum batch of an outside bottle supplier.
When the moulding is in-house, that boundary becomes a matter for discussion rather than a law of nature. Sometimes the factory agrees to a smaller run because it decides for itself how to load its own machine.
You have to ask directly. In-house moulding does not lower the minimum by itself; it lowers the factory's reluctance to discuss it.
Where the advantage disappears
If you want a shape the group does not mould, it will be bought outside exactly as any other factory would buy it. In-house production covers its own range of shapes, not every shape in the world.
And there is a flip side: a single supplier for the whole chain. If a line in the group stops, everything stops at once rather than one part of it.
What to ask the manufacturer
Which components are made in-house and which are bought: bottle, cap, pump, tube, carton, label.
Whether there is a catalogue of stock shapes, and whether you can see it before the price conversation.
Whether the minimum drops when you use their own shapes, and by how much.
Who owns the tooling if it is made for you, and whether you can take it if you move to another factory.
And the tooling lead time stated separately from the production lead time.
