The specific process of importing raw materials for chemical companies:

Preparation before the arrival of goods at the port: Determine the HS code of the imported chemical products, apply for an import license (if necessary), prepare declaration materials (such as commercial invoices, packing lists, bills of lading, certificates of origin, quality inspection reports, etc.).
Declaration of goods upon arrival at the port: declare the goods to the customs within the specified time, submit the declaration materials, and fill out the customs declaration form. The customs will review the customs declaration form, including the authenticity, accuracy, and completeness of the declaration materials.
Goods inspection: Customs may inspect imported chemicals, including unpacking inspection and sampling testing. For certain chemical products, inspection and quarantine are also required to ensure that the quality, safety, and hygiene of the goods meet national standards.
Payment of taxes and fees: Based on the HS code and declared value of the goods, the customs determines the taxes and fees such as customs duties, value-added tax, and consumption tax that should be paid. Importers are required to pay taxes and fees within the specified time frame, otherwise the goods cannot be released.
