The import declaration of intangible assets only needs to provide legal and effective documents and related materials. Taking a patent as an example, it is necessary to provide documents such as patent application, patent specification and patent claim. These documents need to be filed at the customs and applied for customs declaration.
It should be noted that for different types of intangible assets, the procedures and steps of import declaration may be different. If more information is needed, it is recommended to consult a professional import declaration agent or customs.
