The General Administration of Customs of China (GACC) is the regulatory authority responsible for overseeing customs procedures and trade-related matters in China. While I don't have access to specific information on packaging materials from the GACC, I can provide you with some general information about packaging material regulations in international trade.

When it comes to importing or exporting goods, packaging materials are subject to certain regulations to ensure compliance with international standards, safety requirements, and environmental considerations. Here are a few points to consider:

①International Standards: 

Packaging materials used in international trade should adhere to relevant international standards to ensure the safety and integrity of the goods during transportation. Standards such as the International Organization for Standardization (ISO) 9001 and ISO 14001 provide guidelines for quality management systems and environmental management systems, respectively.

②Safety Regulations: 

Different countries may have specific safety regulations regarding packaging materials. These regulations may pertain to the use of certain materials, labeling requirements, or restrictions on hazardous substances. It's essential to understand and comply with the safety regulations of both the exporting and importing countries.

③Environmental Considerations: 

Increasingly, there is a focus on sustainable packaging solutions to minimize waste and environmental impact. Many countries have implemented regulations or initiatives to promote environmentally friendly packaging materials, such as restrictions on single-use plastics or requirements for recyclability or biodegradability.

④Documentation and Labeling: 

When importing or exporting goods, it's important to provide accurate and detailed information about the packaging materials used. This may include descriptions of the materials, their composition, recycling symbols, and any relevant certifications or compliance marks.

⑤Specific Product Requirements: 

Some products, such as food, pharmaceuticals, or hazardous materials, may have specific packaging requirements to ensure product safety and integrity. These requirements can vary depending on the nature of the product and the regulations of the importing country.

It's important to note that regulations regarding packaging materials can vary between countries, and specific requirements may change over time. If you have specific questions or need detailed information about packaging materials regulations in China, it is advisable to consult the General Administration of Customs of China or seek guidance from a customs broker or trade expert familiar with Chinese customs regulations.
