Obtain determination from the U.S. Departments of State or Commerce
The CJ procedure is used when there is doubt to an article being covered under the USML. A Commodity Classification request from Bureau of Industry and Security (BIS) is a formal classification determination and will include the Export Control Classification Number (ECCN) for the item if it is applicable. It is not as simple as submitting a request to in essence say, "hey what's the classification for my item." Whether submitting a CJ or CC, the request must accompany the technical details related to the item. It is not uncommon to have an agent from the DDTC or BIS reach out for additional information, thus the more information and details that are included in the request the better. It is important to note that a CJ or CC is not a license or authorization to export an item, it is only to identify the proper licensing authority for the referenced product or service.
