精萘作為一種化工產品，其進出口需要注意以下幾個關鍵點：

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

　　1. 危險性：精萘屬于4.1類危險貨物，UN編號為1334，因此在進出口過程中需要嚴格按照危險品的相關規定進行操作。

　　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. 包裝：精萘的包裝通常為編織袋（內襯塑料袋），每袋重量為50公斤。液體精萘則可用汽車槽車裝運。

　　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：出口精萘時，首先需要有進出口資質的企業進行操作。危險品需要提前10個工作日提供危包證、MSDS、貨物詳細數據托書，提交船司審核。艙位下來后，需要提好箱子，有了箱封號配合正本證，需要在截申報之前做掉危險品的海事申報。裝柜進港后，上海分為外港和洋山，外港是先進港后報關，洋山是先報關后進港，危險品的計劃也是單獨受理的，而不是根據碼頭的開港計劃來的。危險品進港之后碼頭會發運抵信息，必須要有運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. 進口流程：進口精萘時，需要提前辦理好相關的進口許可證和相關手續，確保符合國內的安全和環保標準。

　　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. 運輸：在運輸過程中，需要確保精萘的安全，避免在高溫或易燃環境中暴露，同時注意防火防爆。

　　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. 儲存：精萘應儲存在陰涼、通風的倉庫中，避免高溫和潮濕，同時應遠離火源和易燃物品。

　　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：在使用精萘時，應嚴格按照產品的說明書進行操作，避免直接接觸皮膚和眼睛，防止吸入粉塵和蒸氣。

　　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.
