White Label
The product with someone else's name on it, and nobody minds
Imagine buying a packet of biscuits under a brand you trust, without realising the exact same biscuits, made in the exact same factory, are also sold under three other brand names on the shelf right next to it, each brand simply putting its own label on an otherwise identical product. That is a white label product in its purest form.
White labelling is when a manufacturer produces a generic, largely undifferentiated product with no customisation beyond the label itself, and sells that same base product to multiple different brands, each of which markets it as their own. It is common in categories where the underlying product genuinely does not vary much between brands, certain packaged foods, basic electronics accessories, and generic personal care items among them.
For the manufacturer, white labelling is a way to sell the same production run multiple times over to different customers, maximising factory utilisation, while for the brand buying it, white labelling is a fast, low investment way to launch a product line without building manufacturing capability of its own.
