Fired clay bricks are one of the traditional construction materials widely used in various civil and industrial projects. However, to ensure quality and compliance with technical requirements before being placed on the market, these products must be assessed and certified in accordance with current technical regulations.

Let’s explore the conformity certification process for fired clay bricks under QCVN 16 with ISSQ Institute of Quality in the article below.

What is QCVN 16:2023/BXD?

QCVN 16:2023/BXD is the National Technical Regulation on construction materials products and goods. It specifies technical limits and management requirements for construction materials listed under regulated categories. This regulation applies to products manufactured domestically, imported, traded, circulated in the market, and used in construction works in Vietnam.

Applicable entities include:

• Organizations and individuals producing, importing, trading, and using construction materials
• Conformity certification bodies and testing organizations
• State management agencies related to product quality

According to regulations, Group 2 construction materials are those that, under normal conditions of use, still pose potential risks to human safety, property, and the environment. Therefore, these products must be quality-controlled through conformity certification before being placed on the market.

Among them, fired clay bricks are one of the products subject to mandatory conformity assessment.

Why do fired clay bricks need conformity certification under QCVN 16?

Fired clay bricks are construction materials directly involved in structural components; therefore, their quality significantly affects durability, safety, and the lifespan of construction works.

According to Table 1, Part 2 of QCVN 16, fired clay bricks (solid bricks, hollow bricks) are construction material products required to obtain conformity certification in accordance with QCVN 16 – the National Technical Regulation on construction materials.

QCVN 16 specifies that fired clay bricks must meet the following technical criteria:

Conformity certification of fired clay bricks under QCVN 16 is an important basis to ensure that products meet technical requirements and are quality-controlled before circulation and use in construction works. At the same time, it is also a necessary step for enterprises to comply with management regulations and enhance product reliability in the market.

Benefits of conformity certification for fired clay bricks

Conformity certification under QCVN 16:2023/BXD not only meets management requirements but also brings practical value to enterprises and products in the market.

1. Ensuring product quality and consistency

Through testing and evaluation, products are controlled based on specific technical indicators such as compressive strength and water absorption, ensuring consistent quality across production batches.

2. Enhancing reputation and competitiveness

Products with conformity certification demonstrate transparency and compliance with technical regulations, thereby building trust with customers, partners, and investors.

3. Facilitating distribution and use in construction projects

Having full certification and declaration of conformity makes it easier for products to be accepted in construction projects, especially those requiring strict material quality control.

4. Supporting risk control in production and business

The conformity assessment process helps enterprises detect and promptly correct quality issues, thereby minimizing risks associated with non-conforming products.

5. Meeting management requirements and reducing legal risks

Conformity certification serves as a basis for conformity declaration and product circulation, helping enterprises avoid difficulties during inspection and quality supervision activities.

Conformity certification is not only a requirement but also a tool that helps enterprises improve product quality, enhance reliability, and create sustainable competitive advantages in the construction materials sector.

Conformity certification process for fired clay bricks under QCVN 16

To place fired clay bricks on the market in compliance with technical requirements under QCVN 16:2023/BXD, enterprises need to follow these basic steps:

1. Receive application for certification registration
2. Sign a science and technology service contract
3. Conduct survey and assessment
4. Complete documentation after assessment
5. Review documentation and issue certificate (if compliant)
6. Conduct surveillance assessment (not exceeding 12 months per cycle)
7. Conduct recertification assessment (certificate validity: 3 years)

Implementing conformity certification for fired clay bricks under QCVN 16:2023/BXD not only helps enterprises ensure compliance with technical requirements but also enhances reputation and competitiveness in the construction materials market.

Through a systematic certification process—from initial assessment to periodic surveillance—product quality is consistently controlled, minimizing risks during circulation and use. This also forms an important foundation for sustainable development and long-term trust with partners and customers.
