Test Reports – Certificate of Analysis

Quality and consistency are essential when choosing a reliable sawdust briquette charcoal supplier. At AVC Charcoal, we believe that product quality should be supported by measurable results and transparent documentation.

To further verify our product quality, AVC Charcoal has conducted independent analyses through Vinacontrol, a leading inspection and conformity assessment organization in Vietnam. Our available quality documentation includes four analysis reports for Grade A sawdust briquette charcoal and one analysis report for Grade B.

These reports provide customers with additional information about the key technical characteristics of our charcoal products.

Independent Quality Analysis by Vinacontrol

The Vinacontrol analysis reports are an important part of AVC Charcoal's quality documentation. Independent testing helps provide objective information about important parameters such as ash content, moisture, fixed carbon, calorific value, volatile matter and sulfur ratio.

The reports cover both our premium Grade A and export-standard Grade B products, allowing customers to better understand the specifications of each grade.

Grade A Sawdust Briquette Charcoal – Premium Quality

Grade A is AVC Charcoal's premium sawdust briquette charcoal and one of our best-selling products for export markets.

It is manufactured in a hexagonal shape with a center hole, providing stable combustion and a long burning time.

Grade A Specifications

With 80–90% fixed carbon, less than 6% ash content and a calorific value of approximately 7,750 Kcal/kg, Grade A is designed for customers looking for premium-quality sawdust briquette charcoal with stable and extended burning performance.

Grade B Sawdust Briquette Charcoal – Export Standard

Grade B is another export product from AVC Charcoal, offering a different specification level for customers with specific requirements.

It is also produced in a hexagonal shape with a center hole and is suitable for international markets.

Grade B Specifications

Grade B has a fixed carbon specification of 70–80%, a calorific value of approximately 7,500 Kcal/kg, and a burning time of approximately 4–5 hours.

Four Grade A Reports and One Grade B Report

AVC Charcoal currently has four independent analysis reports for Grade A and one analysis report for Grade B.

Having multiple analysis reports for Grade A provides additional documentation of product quality across different samples, while the Grade B report demonstrates the quality characteristics of our export-standard product.

Our Commitment to Verified Quality

Independent testing is an important complement to AVC Charcoal's internal quality control system. From selected sawdust raw materials to drying, carbonization, briquetting, grading and packing, our production process is monitored to maintain stable product quality.

The Vinacontrol Certificate of Analysis reports provide international customers with additional technical information when evaluating AVC Charcoal products.
