Claim & Outline• Claim: New U.S. security

initiatives improve U.S. homeland security and have ancillary benefits, such as improved productivity and reduced pilferage (“win-win”).

• Outline:• CSI, ‘pushing back the borders’• Off-shoring and supply chain

productivity• Importance of foreign trade to

the U.S. economy• Example

• Goal• Pre-screen ocean containers at foreign ports• Stop contraband/weapon before departure• “Distribute” screening processes

• The good• Uses (potential) idle time at foreign ports to

conduct screening• Have forced shippers to improve asset visibility

• The not so good• Information timing requirements• Disruptive effects on port export or

transshipment operations and supply chains?

CSI + 24 hour rule

• Carriers and/or NVOCCs must submit cargo declaration 24-hours prior to loading a vessel at a foreign port

• Much earlier than previous (hours prior to arrival)

• Freight description• “precise narrative” or 6-digit commodity code• No more: “freight-all-kinds”, “various retail

products”, …• Difficult for consolidators?

• Requires automated data transfer to CBP• Confidentiality • Rule allows targeting of containers at CSI ports

Supply Chain Productivity

• A key reason for off-shoring is cost• Costs under consideration:

• Product• Logistics

• Transportation• Inventory• Storage

• If total cost is lower off-shore, then consider going off-shore

Effect of Lead Time on Profit

• Lead Time: the time it takes to move a good from origin to destination• Geographical separation of manufacturing and market results in:

• Longer lead times (bad)• Higher lead time variability (bad)• Lower unit production costs, if component manufacturing occurs in an

inexpensive labor market (good)

• Decreases in lead time mean and variability and in unit production costs help justify the separation

• Costumer service level (CSL): the probability a customer will find the desired product on the shelf

• Safety stock (SS): the amount of extra inventory kept on hand to insure the CSL is achieved.

• China is the “world’s largest factory” in the early 21st century, it produces:

• More than 50% of the world’s cameras

• 30% of the air conditioners and TVs

• 25% of washing machines

• Almost 20% of refrigerators

• More than 33% of DVD-ROM drives and personal desktop and notebook computers

• About 25% of its own mobile phones, color televisions, personal digital assistants, and car stereos

• China’s consumption rate grew annually at about 8.8% to 10.1% from 2000-2003

• Color televisions sets in almost every urban home

• Refrigerators and washing machines in more than four out of five homes

• Videodisc players and air conditioners in 50% of homes

• Microwave ovens in almost 1/3 and computers in 1 out 5

• Biggest market for cell phone with 200 million in use and average monthly sale of about $2 million

•Statement: “CSI has forced us into improving visibility … haven’t seen any negative.”•However, there may be situations where inefficiencies may occur. We illustrate with an example.

Consider the following two-scenario example. For both scenarios:•Goods move from origin port (e.g., Singapore) to destination port (e.g., LA)•Single product is shipped in units of container loads•Vessels leave the origin for the destination periodically•Total travel time is a fixed, known number of days•Objective: keep customer service level constant using safety stock

•Port of origin is CSI compliant•Each container may be inspected at origin port before it is loaded on a vessel bound for the destination port•If a container is selected for screening, the inspection time is variable•All containers arriving at destination port receive ‘green lane’ treatment and are not inspected•20% likelihood of ‘role over’ for inspected containers•Time between sailings is 7 days

Scenario 1: Inspect at origin port
