White Label (WL) refers to products manufactured by one company but sold under another company's brand name. The original manufacturer removes their own branding and applies the buyer's logo, packaging, and identity — making it appear as if the buyer produced it themselves.
In white labeling, you take an existing, already-manufactured generic product and rebrand it with your own logo, packaging, and sometimes minor customizations. It's a fast way to launch a product without developing it from scratch.
