In South China, the familiar wharves of Nansha and Xinsha in Guangzhou, Shekou and Yantian in Shenzhen, as well as the airports in Guangzhou and Shenzhen, still stand firmly there. They open their arms, as if they are warmly welcoming every friend who comes from afar. These wharves are not only the pride of South China, but also a beautiful scenery of our country. With their broad minds and powerful functions, they have accepted one ship after another full of goods, and have made great contributions to the country's economic development. 
Bulk dangerous goods to be imported into South China can only be sent to those familiar terminals. Once there, the goods are split and then loaded onto China-Hong Kong dangerous goods trucks and shipped to all parts of the country. Although this process is somewhat complicated, every step is essential, and every operation requires rigor and meticulousness. Customs declaration documents for import of dangerous goods** include waybills, packing lists, commercial invoices, foreign trade contracts, MSDS in Chinese and English, and certificates of origin. These documents are like certificates and guides, which provide a guarantee for the smooth customs clearance of goods. Before importing, it is also necessary to confirm the customs code of the goods. This code, like a person's ID card, is a symbol of the identity of the goods. Through the customs code, you can query the declaration elements, regulatory conditions, import tax rates and other information of the goods. This information is crucial for importers, they are the basis and guide for decision-making. 
The photoresist process is a delicate and complex process. After the coating is developed, the ** part is dissolved, and the un** part remains, and this coating material is a positive photoresist. If the **part is retained, but not dissolved, the coating material is a negative photoresist. These photoresists, according to the different light sources and radiation sources, are divided into ultraviolet photoresists (including ultraviolet positive and negative photoresists), deep ultraviolet photoresists, X-ray adhesives, electron beam adhesives, ion beam adhesives, etc. Each of them has its own unique characteristics and offers a variety of possibilities for semiconductor manufacturing. The next step is the introduction of the import photoresist customs clearance process: after the importer signs the import contract with the foreign businessman, the foreign businessman needs to prepare the relevant chemical raw material documents and label them abroad, and then ship them to the domestic port. When the imported chemical raw materials arrive at the port, it is necessary to change the order and pick up the goods. Then comes the steps of inspection and customs declaration. Customs will review the value of the goods, issue a tax bill, and then the importer needs to pay the tax. Finally, after the goods are released, domestic logistics can be arranged to deliver the goods to their destination. The process is somewhat complex, but every step is essential. It is precisely because of these rigorous operations and meticulous services that we are able to smoothly clear the customs of the imported photoresist and deliver it to the destination.
