Natural stone tiles are widely used materials in construction projects. They not only contribute to the overall aesthetics of a building but also directly affect its durability and quality.

However, to ensure technical requirements and safe usability, products need to be assessed for conformity with current regulations before being circulated on the market.

Let ISSQ Quality Institute help you explore the technical requirements and conformity certification process for natural stone tiles under QCVN 16 in the article below.

What Are Stone Tiles?

Stone tiles are construction materials in slab form, which can be natural or artificial, and are used to cover surfaces such as walls, floors, stairs, countertops, or exterior areas. In addition to protecting building surfaces, these materials also play a role in enhancing aesthetic value and durability.

With outstanding characteristics such as high durability, good load-bearing capacity, heat resistance, and a wide variety of colors and patterns, stone tiles are widely used in both residential and industrial construction projects.

Classification of Stone Tiles

Stone tiles are divided into two main groups:

• Natural stone tiles: These are stones directly quarried from nature, such as granite, marble, slate, and travertine. This material offers high durability, unique natural veining, and high aesthetic value. However, it is usually heavy and requires periodic maintenance during use.
• Artificial stone tiles based on organic binders: These are manufactured from natural stone powder combined with binders such as resin and other additives. Their advantages include uniform and diverse colors, good water resistance, lighter weight, and easier installation.

To control quality and ensure safety during installation and use, stone tiles, especially natural stone tiles, need to be assessed and certified for conformity with QCVN 16 before being placed on the market.

What Is QCVN 16:2023/BXD?

QCVN 16:2023/BXD is the National Technical Regulation on construction material products and goods. It specifies technical characteristic limits and management requirements for products within its regulatory scope. This regulation applies to products manufactured domestically, imported, traded, circulated on the market, and used in construction projects in Vietnam.

According to the regulation, Group 2 construction material products are those that may still pose potential risks to human safety, property, and the environment even under reasonable transportation, storage, and usage conditions.

Therefore, these products need to be quality-controlled through conformity certification activities before being placed on the market.

Among construction material products, natural stone tiles are one of the product groups falling within the scope of QCVN 16. Therefore, assessment and conformity certification serve as the basis for determining whether the product meets the technical requirements of the regulation before being circulated and used in construction projects.

Why Do Natural Stone Tiles Need Conformity Certification under QCVN 16?

According to QCVN 16, natural stone tiles must comply with the provisions of TCVN 4732:2016. This standard applies to slabs processed from natural stone blocks belonging to granite, quartz stone, marble, limestone, slate, and other groups, used for cladding and paving in construction works.

QCVN 16 stipulates that natural stone tiles must meet the following technical criteria:

Conformity certification for natural stone tiles under QCVN 16 serves as the basis for ensuring that products meet technical requirements and are quality-controlled before being used in construction works. At the same time, it also helps enterprises comply with management requirements and improve product credibility in the market.

Benefits of Conformity Certification for Natural Stone Tiles under QCVN 16

Conformity certification not only helps natural stone tile products meet technical requirements under QCVN 16 but also brings many practical benefits to enterprises and business activities:

Ensure product quality

• Confirm that natural stone tiles meet the technical criteria required by the regulation.
• Reduce risks related to durability, load-bearing capacity, and abrasion resistance during use.

Enhance credibility and competitiveness

• Build trust among customers, partners, and investors.
• Strengthen brand image in the construction materials market.

Facilitate circulation and distribution

• Certified products with complete documentation help make distribution transparent and clear.
• Make it easier to participate in construction projects requiring material quality control.

Support import and business activities

• Facilitate the inspection process for imported goods.
• Limit risks related to documentation and procedures when bringing products to market.

Maintain stable product quality

• Through periodic assessment and surveillance activities.
• Help enterprises better control production processes and raw material sources.

Conformity certification for natural stone tiles is not only a technical requirement but also a tool that helps enterprises improve product quality and achieve sustainable development in the market.

Conformity Certification Process for Natural Stone Tiles under QCVN 16

To place natural stone tile products on the market in compliance with the technical requirements of QCVN 16:2023/BXD, enterprises need to carry out conformity certification according to the following basic steps:

Step 1: Receive certification registration documents

Step 2: Sign a scientific and technological service contract

Step 3: Conduct surveys and assessments

Step 4: Complete documentation after assessment

Step 5: Review documents and issue certification (if compliant)

Step 6: Conduct surveillance assessments at least once every 12 months

Step 7: Carry out recertification assessment after certificate expiry (certificate validity: 3 years)

Conformity certification for natural stone tiles under QCVN 16 is the basis for ensuring that products meet technical requirements and are quality-controlled before being used in projects and circulated on the market. Through assessment, certification, and surveillance activities, enterprises can proactively control product quality while enhancing credibility in the eyes of customers and partners.

In the context of increasingly strict requirements for construction material quality, carrying out conformity certification not only helps products comply with current regulations but also contributes to creating a foundation for the stable and long-term development of enterprises.
