Further description of specific requirements is provided for the reference of relevant personnel: 

　　1. Pay attention to the regulations, practices, tariffs, and customs of the importing country regarding packaging.
　　Many countries have certain regulations on the packaging of imported goods. If these are not met, fines may be imposed, heavy taxes may be levied, or imports may even be prohibited. Generally, countries prohibit the use of straw, hay, newspapers, books, raw cotton, branches, old materials, or plant materials that are prone to harbor pests and parasites as padding.

　　Since packaging is related to tariff assessment, the freight of goods is calculated based on the large volume and weight of the products. Therefore, different packaging results in different tariffs and freight charges. The weight of each item is generally stipulated to be below eighty kilograms. Additional fees are charged for oversized and overweight goods. Some countries have different rates for the weight of each package. In addition, due to customs, habits, religions, beliefs, and differences in scripts among various countries, regions, and ethnic groups, there are significant variations in the shape of packaging, the graphics of packaging, colors (see appendix), numbers, and texts. In the international market, the packaging's suitability often affects the sales of products.

　　2. The packaging method must be scientific and reasonable.
　　It should be sturdy and reliable, labor-saving and material-saving, ensure transportation safety, and save freight. The design should choose box types with less material and larger capacity, with reasonable packing arrangements, making more use of disassembly and assembly; efforts should be made to compress the packaging volume. In terms of packaging types, specifications, capacity, materials, shapes, structures, printed marks, as well as the placement, padding, sealing methods, terminology, and inspection requirements of the goods, it is essential to comply with the relevant standards for the packaging of export goods.

　　4. Handling of transportation marks for foreign and domestic transport.
　　For marks common to both foreign and domestic transport that comply with the provisions of Article 3, they can be directly printed on the outer packaging. However, marks used only for domestic transport, such as those from the Guangzhou Procurement Supply Station of the Ministry of Education, xx factory sending (out), etc., should be written on a small wooden board and temporarily nailed to the outer surface for removal during external transport.

　　5. The writing in Chinese and foreign languages must be accurate and easy to understand, avoiding random writing, drawing, or alterations. To accommodate the current situation of Hong Kong, Macau, and overseas compatriots, traditional Chinese characters should be used as much as possible.

　　6. Requirements for neutral packaging.
　　Neutral packaging is a type of product packaging that does not indicate the country of origin, place names, or factory names, nor does it display original trademarks and brand names. As a means of promoting export products, we adopt it mainly to break through high tariffs and unreasonable quota restrictions imposed by certain countries and regions, allowing our products to enter these markets. Currently, neutral packaging is divided into unbranded neutral packaging and branded neutral packaging, aimed at expanding sales channels to adapt to the characteristics of the international market. For example, exporting teaching instruments should adopt neutral packaging, which is very beneficial. The packaging in the international market is increasingly developing towards convenience for display, sales, carrying, and use, and is also evolving towards scientific, advertising, and artistic development. We should conduct regular research and continuously improve packaging to serve export revenue.
