Before Quarth., there was ISN (Import Sourcing Négoce). For over 10 years, we sourced custom packaging and products for French brands across all sectors.
Thousands of orders, hundreds of references, dozens of partner factories. This experience taught us one essential thing: between the brand that buys and the factory that manufactures, there are often too many middlemen.
An agent in China, an importer in France, a distributor. Each takes their margin. Result: some brands pay two to three times the actual manufacturing price without knowing it.
Quarth. was born from this observation, and the desire to address it.
« We saw how the distribution chain works. We chose to step out of it. »
We are not an online catalogue. We are a human contact, reachable, who knows your files.
Our purchasing audit service is simple: submit your current purchasing conditions. We analyse them, challenge them, and tell you honestly whether you're buying well — or whether we can do better.
No empty promises. No hidden commissions. Just transparency.
If your prices are good, we'll tell you. We prefer a trust-based relationship over a forced sale.
A single contact follows your file from start to finish. No support tickets, no bots.
