TSCB refers to Tiansheng Cross-Border Supply Chain (Guangdong) Co., Ltd., a Chinese cross-border logistics company established in 2019 and headquartered in Guangzhou. The company focuses mainly on export logistics between China and the United States, serving cross-border e-commerce sellers, foreign-trade businesses, brands, and Amazon FBA shippers that need transportation, customs, warehousing, and delivery services.
TSCB's main services include international air freight, international ocean freight, full-container shipping, overseas warehousing, and local delivery in the United States. Its ocean services combine shipping-space arrangements with services such as customs declaration, container pickup, delivery, and IPI rail transportation, while its air services use flights to major US airports for customers that need faster replenishment.
The company also operates overseas warehouse and local distribution resources in the United States. TSCB states that its network combines self-operated overseas warehouses with local truck fleets, allowing cargo to move from international transportation into warehouse handling, container pickup, truck delivery, Amazon FBA delivery, commercial-address delivery, or transfer to third-party warehouses. Its service network includes operations in several Chinese cities as well as locations in Los Angeles and New York.
TSCB has developed digital logistics systems to support shipment management and Tracking. The company describes online ordering, real-time routing, API connectivity, and shipment visibility across logistics stages. This is particularly useful for FBA and commercial freight because a shipment can pass through export handling, international transport, customs clearance, an overseas warehouse, and local delivery before reaching its final destination.
How to Track TSCB packages
To Track a TSCB shipment on 4Tracking, enter the tracking or shipment number in the tracking field. Choose TSCB from the carrier list if necessary, or allow 4Tracking to automatically identify the carrier when the number can be detected, then click the Track button. The results page will show the available Tracking events and the latest recorded shipment status.
TSCB also states that its self-developed logistics system provides full-route shipment visibility and real-time logistics information. Because many TSCB movements involve commercial freight, Amazon FBA shipments, containers, or warehouse deliveries rather than only small consumer parcels, the reference supplied to the shipper may be described as an order number, shipment number, or logistics reference rather than a conventional postal tracking number.
TSCB tracking number formats
TSCB does not publish a universal tracking-number format on its official public website. There is no verified rule specifying a fixed prefix, exact length, or required combination of letters and digits that applies to every TSCB shipment.
For reliable package tracking, use the exact logistics number provided by TSCB, the sender, seller, freight documentation, or shipping confirmation. Do not add an assumed prefix or modify the number to match an unofficial example. Commercial shipments can also have several different references, such as an internal order number, container number, Amazon shipment reference, or a number belonging to a final delivery provider, and these references are not necessarily interchangeable.
If the number does not return a result, confirm with the sender which reference is intended for Tracking. This is especially important for FBA freight because a warehouse code, Amazon shipment ID, booking number, and TSCB logistics reference can all appear in the same shipment documentation.
TSCB delivery times and supported examples
Delivery time depends on the selected TSCB service, origin warehouse, flight or sailing schedule, customs processing, destination, warehouse appointment, and final-mile delivery. The company publishes service-specific timing examples rather than one guaranteed delivery period for all shipments.
Air freight from China to the United States
TSCB states on its official website that its fastest US air-freight services can be signed for in as little as 3 calendar days. A separate air-service page describes channels intended for fast replenishment with delivery as fast as approximately 3-7 days. These figures relate to selected air products and should not be treated as a universal promise for every air shipment.
Ocean freight from China to the United States
For ocean transportation, TSCB advertises selected services with delivery as fast as approximately 11 calendar days. The actual timeframe varies substantially according to the shipping line, departure port, US arrival port, customs clearance, container availability, inland transfer, and destination warehouse. Ocean freight should therefore be evaluated according to the specific route booked by the shipper.
United States warehouse and local delivery
TSCB's official information about its overseas warehouse operations describes US local delivery examples of approximately 2 days for certain services and approximately 3-6 days for others. These examples concern local transportation after goods are already positioned in the United States and should not be confused with the complete China-to-US transit time.
A shipment can also remain without a new Tracking event while it is aboard an aircraft or vessel, waiting for customs clearance, awaiting container pickup, moving to an overseas warehouse, or waiting for an Amazon or commercial delivery appointment. Peak seasons, customs inspections, port congestion, flight or sailing changes, and warehouse availability can extend the published service estimates.
How to contact TSCB about shipment issues
If package tracking has stopped updating, first confirm that you are using the correct TSCB shipment reference and review the latest recorded event. For goods purchased from an online seller, contacting the seller or sender is often the most effective first step because the shipper normally has the original booking information and can communicate directly with the logistics provider.
TSCB lists the business consultation telephone number 020-3636 8936 on its official website. The company also provides an Enterprise WeChat contact option and lists luke@tianshengsc.com for complaints and suggestions. Its Guangzhou headquarters is listed at Room 101, Building 2, Wanggang Quantum Creation Space, Baiyun District, Guangzhou, China.
When asking about a delayed or missing shipment, provide the TSCB tracking or order number, departure location, US destination, selected service if known, and the date and wording of the most recent Tracking update. For FBA freight, including the destination Amazon warehouse code can also help identify the shipment, but it should be supplied alongside the logistics reference rather than treated as a replacement for it.
Frequently asked questions about TSCB package tracking issues
Why is my TSCB tracking number not working?
The number may have been entered incorrectly, the shipment may not yet have received its first system update, or you may be using another reference such as an Amazon shipment ID or container number. Copy the TSCB logistics reference exactly as supplied by the sender and confirm the correct number if no result appears.
What does a TSCB tracking number look like?
TSCB does not publicly specify one universal tracking-number pattern. Its official website does not provide a verified fixed prefix, character count, or standard letter-and-number structure, so the safest approach is to use the exact shipment or order reference issued for your cargo.
Why has my TSCB package tracking stopped updating?
Tracking can pause while cargo is in international transit, undergoing customs clearance, waiting for container pickup, moving between warehouses, or awaiting a delivery appointment. These stages do not always generate frequent scans. If the shipment remains unchanged beyond the expected timeframe for the booked service, contact the sender or TSCB.
How long does TSCB shipping from China to the United States take?
The timing depends on the service. TSCB advertises selected air services as fast as 3 calendar days, with another air channel listing approximately 3-7 days, while selected ocean services are advertised as fast as 11 calendar days. These are service-specific examples rather than guaranteed delivery times for every shipment.
Does TSCB provide shipment Tracking throughout the journey?
TSCB states that its self-developed logistics system provides full-process shipment visibility and real-time routing information. Available events can cover several stages of the supply chain, although the frequency and detail of updates depend on the service and transportation stage.
Does TSCB deliver directly to Amazon FBA warehouses?
Yes. TSCB provides logistics services for Amazon sellers and delivers to FBA warehouses as part of its US transportation network. The company also handles deliveries to commercial addresses and third-party overseas warehouses, depending on the selected service.
Why does my TSCB shipment have several different reference numbers?
Cross-border commercial freight can involve an internal logistics order, booking reference, container number, Amazon shipment ID, warehouse reference, and possibly a separate local-delivery number. Use the TSCB reference intended for package tracking and keep the other identifiers available when contacting customer service.
Who should I contact if my TSCB shipment is delayed or missing?
For an e-commerce order, contact the seller or sender first because they usually have the complete shipping record and can open an inquiry with TSCB. Shippers can also contact TSCB through its official business telephone number, Enterprise WeChat channel, or published complaints and suggestions email address.
