Frequently asked

Is Chinese quartz slab good quality?
It can be, but the country of origin alone does not decide quality. The result depends on the slab you choose, the fabrication work, and the installation. Ask for samples, check drawings, and confirm who handles each step before you order.
Do all quartz slabs from China look the same?
No. Slabs can differ in color, pattern, grain size, and finish. Even the same product name can vary from one production lot to another, so review a real sample or photo from the material you will receive.
What are quartz slab certifications for export?
They are documents such as product specifications, test reports, inspection records, and packing details that show the slab matches what the buyer agreed to. For a beginner, the main point is to ask which papers are required for the project or destination before placing an order.
Do all countries require the same export documents for quartz slabs?
No. Different buyers, projects, and destinations may ask for different paperwork, so confirm the exact list before production starts. A safe starting point is to request traceable quality inspection records and export-grade packaging details, then add any project-specific test or declaration documents.
What is the real difference between engineered quartz and natural stone?
Engineered quartz is a manufactured product made from crushed quartz mixed with resin, pigments, and other additives. Natural stone, such as granite or marble, is mined from the earth and cut into slabs. The key difference is that engineered quartz is consistent and non-porous, while natural stone varies in pattern and requires sealing.
Do I need to seal engineered quartz like natural stone?
No, engineered quartz does not need sealing because it is non-porous. Natural stone like granite is porous and should be sealed periodically to prevent stains and moisture damage. This makes engineered quartz easier to maintain for many homeowners.
Is private label quartz the same as just buying quartz from China?
No. Buying quartz from China usually means you purchase standard slabs or finished tops as they are. Private label means the product carries your brand, and you often have a say in the color, finish, edge profile and packaging. The supplier becomes a manufacturing partner rather than just a seller.
Do I need to order a full container to start?
Most Chinese quartz suppliers set a minimum order quantity, and it is often based on a full container load. That said, some suppliers will work with smaller trial orders for first-time buyers. Ask upfront what the minimum is and whether a sample order is possible before you commit.
