Is There Any Concern with Quartz Countertops from China?

Quartz countertops remain one of the most popular choices for kitchen and bathroom remodels due to their durability, ease of maintenance, and stylish appearance. With imported quartz now accounting for over 93% of the US market, some homeowners have concerns about the quality and safety of quartz sourced from China. We’ll examine the key considerations when buying quartz countertops from China.

Overview of Quartz Countertops

Quartz countertops, often referred to as engineered stone, are made from ground quartz crystals combined with resins and pigments. The resins bind the quartz particles together to form a hard, non-porous surface. The main benefits of quartz countertops include:

  • Extremely durable and scratch resistant
  • Non-porous so resists stains
  • Easy to clean and maintain
  • Available in a wide range of colors and patterns
  • Heat and impact resistant

Quartz is one of the most popular countertop materials on the market today along with natural stone and laminate. The majority of quartz now comes from China where large manufactures like Vicostone, Pokarna, and DuPont operate factories.

Are There Quality Concerns with Chinese Quartz?

The rapid growth of quartz manufacturing in China has led some buyers to be wary of quality issues. However, major brands producing quartz in China adhere to strict quality control and performance standards. Here are some key considerations:

  • Reputable Brands – Leading quartz suppliers like Caesarstone, Cambria, and Silestone source some products from China but maintain quality standards. Stick with known brand names.
  • Quality Control – Stringent testing procedures are used by major quartz brands to ensure products meet durability and performance specifications regardless of origin.
  • Certifications – Many brands meet important safety and performance certifications like NSF/ANSI 51 for food contact and GREENGUARD for low VOC emissions.
  • Factory Audits – Suppliers routinely audit Chinese factories to verify compliance with quality procedures and inspect finished products.
  • Reliable Materials – The raw quartz and resins used meet industry standards for purity and performance established by quartz suppliers.
  • Expert Fabrication – The fabrication and installation of the countertops, not just the material itself, also impacts the final product quality.

Key Benefits of Quartz from China

Despite some concerns, quartz sourced from China offers several advantages:

  • Lower Cost – China’s manufacturing expertise allows quartz to be produced efficiently at scale, reducing costs. Savings are passed on to consumers.
  • Innovative Designs – Chinese factories enable brands to innovate with more intricate patterns, colors, and effects at an affordable price point.
  • Enhanced Durability – Manufacturing techniques have improved to make quartz even more scratch, chip, and heat resistant.
  • Consistent Quality – Automated processes allow consistency and uniformity during fabrication for precision fit and finish.
  • Environmental Standards – Many factories have adopted processes to recycle water, reduce waste, and minimize environmental impact.
  • Product Availability – Sourcing from China provides brands with the production capacity to meet the high demand for quartz countertops across North America.

Genuine Certifications Provide Peace of Mind

Seeking out quartz brands that adhere to respected third-party quality and performance certifications can offer reassurance that products from China meet stringent standards. Here are some marks to look for:

  • NSF Certification – Confirms quartz meets sanitation and food safety standards for kitchen use.
  • GREENGUARD – Indicates low chemical emissions and good indoor air quality.
  • ISO 9001 – Verifies effective quality management system to ensure high standards.
  • UL Safety Certifications – Validates electrical safety for quartz with integrated lighting, outlets, etc.
  • Breast Cancer Research Stamp – Shows brand contributes to breast cancer research and education.


Quartz sourced from China remains an excellent choice for countertops that are affordable, stylish, and durable. Leading manufacturers adhere to strict quality control and performance testing to ensure quartz import products live up to expectations. Focusing on reputable brands that meet key third-party certifications provides further peace of mind. With proper fabrication and installation, homeowners can enjoy worry-free performance from their Chinese quartz countertops for years to come.

Frequently Asked Questions About Quartz Countertops from China

Is quartz from China the same quality as US quartz?

Yes, reputable brands use the same quartz composites, manufacturing techniques, and quality control procedures for their countertops whether produced in China or the US. Durability, stain resistance, and performance meet the same industry-leading standards.

What are the risks of low-priced quartz from unknown Chinese manufacturers?

Bargain, low-quality quartz lacking certification and brand recognition has higher risks of defects, impurities that can stain, or poor durability that does not live up to quality quartz. Reputable brands source quartz from select verified factories in China.

Does quartz made in China have dangerous silica dust?

All quartz contains silica dust during the fabrication process which requires safety precautions. However, finished quartz products meet OSHA silica dust safety standards. China manufactures follow the same procedures used worldwide to mitigate risks during fabrication.

Is domestic US-made quartz higher quality than imported quartz?

Not necessarily. Even US brands now source the majority of their quartz from China due to the specialized manufacturing expertise. Domestic products follow the same specifications and strict quality control. The focus should be on selecting reputable certified brands over country of origin.

Should I avoid quartz from China?

With over 90% of quartz now imported from China, avoiding it entirely limits options. Instead, buyers should focus on reputable brands that meet quality and performance certifications. Responsible sourcing from verified suppliers in China generates excellent quartz within an affordable price range.
