Do I really need to visit the factory, or are photos and emails enough?

Photos can be copied and emails are easy to send, so they are not enough on their own. A supplier who owns processing capability will be able to show you their factory live, share recent production footage, and explain exactly how they cut and finish slabs. If they refuse to give you a video call or detailed answers about their workshop, that is a warning sign.

Is Chinese quartz stone any good, or is it all cheap low-quality material?

It is a common mistake to assume all Chinese quartz is the same. There is a wide range — from low-grade slabs to premium products designed for export markets. A serious supplier like YOUSTONE, which has been in the natural stone industry since 2008 and exports to over 18 countries, focuses on higher-end quartz with patterns such as Calacatta styles and solid colors, as well as granite options. The key is to ask for physical samples and verify what the actual product looks like, not just read specifications.

How do I know if a supplier is a real factory or just a trading company?

Trading companies often cannot show you their machines or processing workflow. A genuine factory will handle both material sourcing and cutting in-house, maintain direct relationships with quarries, and be able to walk you through their quality inspection steps. YOUSTONE, for example, structures their delivery in three stages: material procurement from trusted mines, custom processing to your drawings, and quality-checked export packaging. If a supplier cannot explain these stages clearly, they may not have the capability you need.
