精萘作为一种化工产品，其进出口需要注意以下几个关键点：

　　As a chemical product, the import and export of refined naphthalene should pay attention to the following key points:

　　1. 危险性：精萘属于4.1类危险货物，UN编号为1334，因此在进出口过程中需要严格按照危险品的相关规定进行操作。

　　1. Hazard: Naphthalene belongs to Class 4.1 dangerous goods with UN number 1334, so it is necessary to strictly follow the relevant regulations for dangerous goods during the import and export process.

　　2. 包装：精萘的包装通常为编织袋（内衬塑料袋），每袋重量为50公斤。液体精萘则可用汽车槽车装运。

　　2. Packaging: The packaging of refined naphthalene is usually in woven bags (lined with plastic bags), with a weight of 50 kilograms per bag. Liquid refined naphthalene can be transported by tanker trucks.

　　3. 出口流程：出口精萘时，首先需要有进出口资质的企业进行操作。危险品需要提前10个工作日提供危包证、MSDS、货物详细数据托书，提交船司审核。舱位下来后，需要提好箱子，有了箱封号配合正本证，需要在截申报之前做掉危险品的海事申报。装柜进港后，上海分为外港和洋山，外港是先进港后报关，洋山是先报关后进港，危险品的计划也是单独受理的，而不是根据码头的开港计划来的。危险品进港之后码头会发运抵信息，必须要有运抵信息之后才可以安心等上船了。

　　3. Export process: When exporting refined naphthalene, the first step is for enterprises with import and export qualifications to operate. Dangerous goods require a dangerous goods certificate, MSDS, and detailed cargo data consignment note to be provided 10 working days in advance for review by the shipping company. After disembarking from the cabin, it is necessary to pick up the box, provide the box seal number and original certificate, and complete the maritime declaration for dangerous goods before the cut-off declaration. After the container is loaded into the port, Shanghai is divided into Outer Port and Yangshan. Outer Port is the first port to declare customs, while Yangshan is the first port to declare customs before entering the port. The plan for dangerous goods is also handled separately, rather than based on the port opening plan of the terminal. After the dangerous goods enter the port, the terminal will ship the arrival information, and it is necessary to have the arrival information before we can safely wait for the ship to board.

　　4. 进口流程：进口精萘时，需要提前办理好相关的进口许可证和相关手续，确保符合国内的安全和环保标准。

　　4. Import process: When importing refined naphthalene, it is necessary to obtain relevant import licenses and procedures in advance to ensure compliance with domestic safety and environmental standards.

　　5. 运输：在运输过程中，需要确保精萘的安全，避免在高温或易燃环境中暴露，同时注意防火防爆。

　　5. Transportation: During transportation, it is necessary to ensure the safety of refined naphthalene, avoid exposure to high temperatures or flammable environments, and pay attention to fire and explosion prevention.

　　6. 储存：精萘应储存在阴凉、通风的仓库中，避免高温和潮湿，同时应远离火源和易燃物品。

　　6. Storage: Refined naphthalene should be stored in a cool and ventilated warehouse, avoiding high temperatures and humidity, and should be kept away from sources of fire and flammable materials.

　　7. 使用：在使用精萘时，应严格按照产品的说明书进行操作，避免直接接触皮肤和眼睛，防止吸入粉尘和蒸气。

　　7. Use: When using refined naphthalene, strictly follow the product manual to avoid direct contact with skin and eyes, and prevent inhalation of dust and vapor.
