If you are shipping international Ocean Cargo, you are subject to Importer Security Filing rules. This means that at least 24 hours before your goods are loaded onto an ocean vessel in a foreign port, you must submit ten specific data elements, and the carrier must submit an additional two. At Sky limit Express Delivery Services, we have ample experience in what is known as 10+2 filing, and we will ensure that the required information gets to Customs and Border Protection agency on time.
