CLE is the abbreviation used by Shanghai Clocair International Logistics Co., Ltd., a logistics company based in Shanghai, China. The company operates from the Jiuting logistics area in Songjiang District and focuses on international transport services connecting shipments from China with overseas markets.
CLE's official service portfolio includes dedicated air-freight lines for the European Union, the United Kingdom, the United States, Canada and Australia, as well as sea-freight lines for the United Kingdom, the United States and Australia. The company also describes experience with railway transport and international air freight, giving shippers several transport options depending on destination and cargo requirements.
For several air routes, CLE offers customs-clearance and tax-inclusive services and says it operates a professional customs-clearance team. Its official information also describes dedicated last-mile delivery networks for its self-operated lines and an internally developed logistics system that provides customers with end-to-end shipment data and real-time tracking. CLE's confirmed own local operating presence is in China; overseas delivery coverage should not be interpreted as proof that CLE maintains its own local facilities in every destination country.
How CLE shipment tracking works
To Track a CLE package on 4Tracking, enter the complete tracking number in the tracking field. 4Tracking can attempt to identify the carrier automatically. If CLE is not detected, select CLE manually and click the Track button to open the results page and view the latest available Tracking events.
CLE says its proprietary logistics system provides full-chain shipment data and real-time trajectory queries for its customers. Depending on the route, a package may move through CLE's export handling, international transport, customs clearance and a last-mile delivery network, so package tracking can contain events generated at several different stages of the journey.
CLE tracking number formats
CLE's official public website does not publish a universal tracking-number specification defining a fixed prefix, exact length or required combination of letters and digits. For that reason, a single format should not be presented as applying to every CLE shipment.
Use the tracking number exactly as supplied by the seller, shipper or CLE. Keep all letters, digits and leading zeros unchanged. If automatic detection on 4Tracking does not identify the carrier correctly, select CLE manually rather than altering the number to resemble another logistics company's format.
CLE delivery times and service examples
CLE's public service information does not provide a verified number of transit days for each route, so there is no supported basis for publishing a general delivery-time promise. The company does, however, publish transport-frequency information that helps explain how often some services are scheduled.
For example, CLE states that its European Union air line operates about four to five flights per week, its United Kingdom air line operates more than five flights per week, and its United States air line operates about four to five flights per week. These frequencies indicate planned departure availability and should not be interpreted as four-to-five-day delivery estimates.
For sea freight, CLE states that its United Kingdom, United States and Australia sea lines have weekly sailings. Actual delivery time can still depend on the departure schedule, international transport, customs clearance and final delivery arrangements. Customers should therefore compare the latest Tracking events with the service selected by the sender instead of relying on an unsupported fixed number of days.
How to contact CLE about shipment issues
CLE lists its company address as Room 102, Building A, No. 1501 Jiujing Road, Jiuting, Songjiang District, Shanghai, China. The published telephone number is 19945790385 and the company email address is cle@clocair.com.
When contacting CLE about a delayed or unusual shipment, provide the complete tracking number and any order or shipping information supplied by the sender. This helps identify the correct route and logistics service. If the shipment came from an online marketplace or retailer, contacting the seller or sender can also be useful because they hold the original booking details and can raise a logistics inquiry when necessary.
Frequently asked questions about CLE package tracking issues
Why is my CLE tracking number not working?
The shipment may have been created recently, the first logistics event may not yet be available, or the number may have been entered incorrectly. Copy the complete number again, select CLE manually on 4Tracking if needed and ask the sender to confirm that the package has been handed over.
Can I Track CLE packages on 4Tracking?
Yes. Enter your CLE tracking number on 4Tracking, allow automatic carrier detection or select CLE manually, and click Track to view the available package tracking history.
What format does a CLE tracking number use?
CLE does not publish one universal tracking-number pattern on its official website. Use the exact number provided with your shipment instead of assuming a particular prefix, length or letter-and-digit format.
Why has my CLE Tracking status stopped updating?
A shipment can spend time between recorded events while moving through international transport, customs clearance or a last-mile delivery network. If there is no meaningful update for an unusually long period, contact the sender or CLE with the tracking number.
How long does CLE delivery take?
CLE does not publish a general route-by-route delivery-time table that can be used as a universal estimate. Its official information confirms service frequencies, such as four to five weekly flights on the European Union and United States air lines and more than five weekly flights on the United Kingdom air line, but these are departure frequencies rather than guaranteed transit times.
Does CLE offer sea-freight services?
Yes. CLE officially lists sea-freight lines for the United Kingdom, the United States and Australia, with weekly sailings described for these services. Delivery timing still depends on the specific sailing, customs processing and final delivery arrangements.
Who should I contact if my CLE package appears delayed?
Check the latest package tracking status first. If the shipment remains unchanged beyond the expected service period, contact CLE at 19945790385 or cle@clocair.com and provide the tracking number. For marketplace orders, the seller or sender can also use the original booking information to request an investigation.
