THT Vietnam’s 3-step product quality control process

In the context of an increasingly competitive market, product quality is no longer an advantage, but has become a mandatory requirement for a business to survive and develop sustainably. Deeply understanding this, at THT Vietnam, we consider quality as a compass, a core value that guides all production activities. 

This process is built on international ISO standards, including 3 multi-layered control steps, forming a closed and solid system. Let’s learn more about this quality “fence”.

Step 1:  Check input materials

The quality of a product is determined from the very first step – raw materials. A superior formula or a modern production line cannot produce a good product if the raw materials do not meet the standards. Therefore, the step of raw material inspection is carried out with the strictest and most meticulousness.

• Choosing reputable suppliers: We only cooperate with suppliers with long-standing reputation in the market, with full certification of origin and quality analysis. All suppliers must undergo THT’s rigorous capacity assessment process.
• Comprehensive inspection upon arrival at the warehouse: Every batch of raw materials, no matter how small, must undergo sampling and testing in the laboratory upon arrival at the factory. The tested indicators include: physical properties (color, odor, solubility), chemical indicators (qualitative, quantitative active ingredients). Only batches of raw materials that meet 100% of the input quality standards set by THT are allowed to be put into production.

Step 2: Monitor the production process according to strict ISO standards

After having standard raw materials, the production process is the stage that shapes the final quality of the product. To ensure uniformity and eliminate errors, THT applies a strict production monitoring system, adhering to the principles of ISO quality management standards.

• Production in a closed, controlled environment: The entire production line is operated in a strictly controlled environment in terms of temperature, humidity, and microbiology, minimizing the penetration of foreign factors that may affect the product.
• Internal control system at each stage: Instead of just checking the finished product, we set up quality control points at each stage of production. Our team of technicians and QC staff continuously monitor, measure and record these parameters to ensure that the process has no deviations.
• People are at the heart of supervision: In addition to the modern machinery system, THT’s team of experienced technical staff plays a role in continuous supervision, promptly detecting and handling the smallest abnormalities. This helps prevent errors early, ensuring that products are manufactured according to approved formulas and processes.

Step 3: Inspect finished products before packaging – Final Protection Layer

Before a product is packaged and ready for market, it must pass the final inspection. This step reaffirms all the efforts of the previous two stages, ensuring the finished product is of the highest quality and absolutely safe for users.

Each batch of finished products is randomly sampled and rigorously tested against established standards for each specific product. Tests include:

• Sensory inspection: Evaluate product color, aroma, texture, and clarity to ensure consistency and appeal.
• Physico-chemical testing: Measure important parameters such as pH, viscosity, density, and perform stability tests under different temperature and time conditions.
• Microbiological testing: Ensures the product does not contain harmful microorganisms and meets consumer safety standards.
• Safety and efficacy assessment: Perform skin irritation tests (for cosmetics) and re-test the product’s main functions.
