Anhua Mingyi Bamboo Industry Development Co., Ltd.

Comprehensive Quality Control System

We have established a comprehensive in-house quality control system covering every stage of production, from raw material inspection and carbonization process management to finished product testing, batch traceability, and export packaging. Through standardized operating procedures and strict inspection requirements, we are committed to delivering consistent and reliable bamboo charcoal and shisha charcoal products to customers worldwide.

1. Raw Material Inspection

All incoming bamboo raw materials undergo weighing and moisture content inspection upon arrival. Materials showing signs of mold, excessive impurities, or other quality defects are identified and rejected. This incoming inspection process helps control raw material quality at the source and minimize potential quality risks in finished products.

2. Precise Carbonization Process Control

Carbonization furnace temperatures are monitored throughout the production process to maintain stable operating conditions. Since carbonization temperature directly affects the fixed carbon content and combustion performance of charcoal, we follow standardized production procedures to minimize variations between different production batches.

3. Finished Product Grading and Sorting

After carbonization, finished charcoal undergoes machine-assisted screening followed by manual inspection. Charcoal powder, broken pieces, and other defective materials are removed through this dual-sorting process.

Products are strictly classified into Grade A and Grade B according to established quality requirements. Different grades are stored separately, and mixed-grade shipments are strictly prohibited to maintain product consistency and meet customer specifications.

4. Batch Sampling and Laboratory Testing

Samples are collected from every production batch for quality evaluation. Laboratory tests cover key indicators, including:

• Ash Content: Evaluating the residual ash level after combustion.

• Moisture Content: Monitoring moisture levels to support stable storage and combustion performance.

• Fixed Carbon Content: Assessing an important indicator of charcoal quality.

• Combustion Performance: Conducting practical burning tests to verify combustion duration.

Written inspection records are maintained for each batch to support quality monitoring and product consistency.

5. Batch Retention and Traceability

We retain representative samples corresponding to every shipped container and store them properly for future reference. In the event of a product quality inquiry or dispute, retained samples can be used for comparison and quality traceability.

This batch retention system provides an additional layer of quality assurance and supports more transparent communication with customers.

6. Standardized Packaging and Export Compliance

Our packaging workshop supports OEM packaging solutions, including customized cartons and retail-size packages according to customer requirements.

For exports classified as Class 4.2 dangerous goods, packaging and handling arrangements are carried out in accordance with applicable dangerous goods packaging requirements and relevant sea transportation regulations. This helps ensure that shipments are prepared to meet the required transportation and packaging conditions.

Quality Assurance Commitment

We believe reliable charcoal quality comes from consistent control throughout the entire manufacturing and delivery process. By combining raw material inspection, precise carbonization management, dual sorting, laboratory testing, batch retention, and standardized packaging, we strive to provide dependable products and professional supply services for global wholesale buyers, distributors, and OEM partners.
