How to Manage the Timing of CY Open, Customs Cut-Off, and Gate Cut-Off? This Article Tells You!

Opening Time refers to the earliest time an empty container can be picked up. After the shipper books space, the shipping line issues a Shipping Order (S/O) detailing all key dates so the shipper can arrange container pickup and loading. If the opening time has not yet been reached, the empty container cannot be collected from the terminal or the location designated by the shipping line.
SI Cut-off Time, also known as the document cut-off time, is the latest deadline for the shipper to submit the required information for bill of lading preparation to the shipping line. In other words, it is the final time the shipping line allows changes to the bill of lading format. Before this deadline, the format and details can be revised multiple times; after it, any amendments will incur amendment fees. There is no standard cut-off time—it varies by shipping line, with some setting it on the sailing date and others within one week after departure. If you are unable to submit the bill of lading instructions to the shipping line by this deadline, you can apply for an SI Late Come, i.e., request an extension of the SI cut-off time. Generally, the shipping line will grant the shipper a few extra hours.
S/I CLOSING is a specific requirement for U.S. trade lanes, differing from other shipping routes. The freight forwarder must submit cargo details to the carrier at least 48 hours before vessel departure. The carrier is then required to transmit the cargo information to U.S. Customs via the AMS system at least 24 hours prior to sailing, and must provide the actual shipper and consignee to U.S. Customs.
AMS --America Manifest System, also known as the Anti-Terrorism Manifest Fee or information fee. All cargo imported into the U.S. (from anywhere in the world) requires this data submission to U.S. Customs, including detailed gross weight, dimensions, actual shipper and consignee, and product descriptions in both Chinese and English. It is generally required to be completed one day before the customs cut-off.

It is the deadline set by the shipping line for submitting the final shipping instruction (commonly known as the release note). The terminal usually starts sorting through the dock receipts that have cleared customs a few hours before vessel departure to prepare for loading. This cut-off time is also the customs closing time.
