The base paper used by China's carton production enterprises can be simply divided into imported base paper and domestic base paper according to the origin; for example, according to the varieties of base paper, it can be divided into kraft paper (also known as kraft paper board in China), corrugated paper, white paper used for high-grade packaging and printing, kraft paper hanging and kraft paper coated board.

　　由于纸箱行业在的快速发展,对原始论文的需求逐年增加,尤其是涂布牛皮纸板,因为它的优点盒装板纸和涂布白纸,还有盒装纸板的强度和白色纸张印刷适性,所以进口量大幅增加。近年来,虽然国内原始论文的整体质量大大改善,但与外国生纸的质量相比仍有差距,即使个人造纸厂可以达到同样水平的外国,但是在一些low-gram重量,高强度的牛皮纸和瓦楞纸生产,由于能力有限,仍无法满足需求。

　　Due to the rapid development of the carton industry in China, the demand for original papers is increasing year by year, especially for coated kraft board. Because of its advantages of box board paper and coated white paper, as well as the strength of box board and the printability of white paper, the import volume is greatly increased. In recent years, although the overall quality of domestic original papers has been greatly improved, there is still a gap compared with the quality of foreign raw paper. Even if the individual paper mill can reach the same level in foreign countries, but in some low gram weight, high-strength kraft paper and corrugated paper production, due to the limited capacity, it still can not meet the demand.

　　大多数仍依赖进口。于进口原料,检验检疫部门具体规定:根据商检的规定法律,商检列表中列出的商品必须接受检验检疫机构或其指定的检验部门,没有检查,不得出售或使用。我国进口纸箱用的绝大多数原纸是属于法定验货的，所以必须通过验货。目前，检验检疫部门在检验这些文件时，检验标准大致如下。

　　Most are still dependent on imports. As for the imported raw materials, the inspection and Quarantine Department of China specifically stipulates that: according to the provisions and laws of the commodity inspection, the commodities listed in the commodity inspection list must be subject to the inspection and quarantine institution or the inspection department designated by it. Without inspection, they cannot be sold or used. Most of the base paper used in the imported cartons belongs to the legal inspection, so it must pass the inspection. At present, when the inspection and quarantine department inspects these documents, the inspection standards are roughly as follows.

　　法律、法规规定必须执行的标准或者其他必须执行的检验标准;没有法定标准或者法律、法规规定必须执行的其他检验标准的，可以按照双方合同约定的标准执行。法律、法规的强制性标准于合同约定的，按照合同约定的标准执行。

　　The standards or other inspection standards that must be implemented according to the provisions of laws and regulations; if there are no legal standards or other inspection standards that must be implemented according to the provisions of laws and regulations, they can be implemented according to the standards agreed by both parties in the contract. If the compulsory standards of laws and regulations are lower than those stipulated in the contract, the standards stipulated in the contract shall prevail.

　　没有上述两点之一的，可以按照生产国标准、有关标准或者检验检疫机构规定的标准进行检验。没有合适的检测标准的，应当选择经批准的内部方法标准。

　　If there is no one of the two points mentioned above, the inspection may be carried out in accordance with the standards of the producing country, relevant international standards or the standards prescribed by the state inspection and quarantine organ. If there is no suitable test standard, the approved internal method standard shall be selected.
