SIYUNDA is one of China's major express delivery companies, operating since the early 2000s. The carrier has built a substantial network across mainland China and expanded into international shipping corridors, serving both B2B logistics and e-commerce fulfillment. With sorting facilities in major cities and partnerships with regional carriers, SIYUNDA handles millions of parcels annually for small businesses, online retailers, and individual shippers.
The company operates as a cost-effective alternative to premium carriers in China, focusing on reliability and competitive pricing. SIYUNDA's infrastructure connects hundreds of distribution points, making it a practical choice for domestic-to-international transitions and regional consolidation services.
China's express delivery sector is one of the world's largest by volume. SIYUNDA competes alongside giants like SF Express and ZTO, capturing market share through flexible pricing and decent coverage. The carrier's strength lies in handling mid-volume shippers who need reliability without the premium costs of top-tier operators. During peak seasons, SIYUNDA processes tens of millions of parcels, requiring robust tracking systems and quick data updates.
SIYUNDA's service portfolio includes standard domestic parcels, time-sensitive options, and cross-border shipping. Most customers use the standard service for regular packages, which typically takes 2-5 business days within China. For international shipments, SIYUNDA partners with customs brokers and partner carriers at border crossings to manage clearance and final delivery.
The carrier issues tracking numbers that follow a standardized format. These numbers activate in the SIYUNDA system within 2-4 hours of handoff. For international parcels, tracking hand-offs to partner carriers at customs, so updates may temporarily pause during border processing. Return and refund shipments are common, and SIYUNDA supports reverse logistics for e-commerce sellers managing high return volumes.
Paxlo connects directly to SIYUNDA's tracking database, pulling real-time status updates for every parcel. When you enter a SIYUNDA tracking number into Paxlo, the app immediately retrieves the latest location, estimated delivery window, and handling notes. Updates typically sync every 1-2 hours, so you see changes almost as soon as they happen in the carrier's system.
For domestic shipments, Paxlo displays the current sorting facility or courier location. For international parcels, you'll see handoff confirmations at customs, expected transit times between countries, and final delivery status. The app handles the complexity of multi-carrier routing automatically, so if your SIYUNDA package transitions to a last-mile partner, Paxlo keeps tracking active through that transition.
Many users track multiple SIYUNDA parcels simultaneously without confusion. Paxlo organizes shipments by status, showing what's in transit, what's out for delivery, and what's been completed. If a package is delayed or stuck at a sorting facility, the app makes it obvious, and you can tap for more details or contact the carrier directly from within Paxlo.
SIYUNDA tracking numbers are typically 12-13 digits long. Simply paste the number into Paxlo's search field, and the app auto-detects the carrier and retrieves tracking data. No need to manually select SIYUNDA or guess the format, Paxlo's recognition system handles it instantly. You can save frequently monitored shipments as favorites for quick access on your phone's home screen.
SIYUNDA's coverage is strongest in urban and suburban areas. Deliveries to remote rural regions may take longer or route through partner networks. Paxlo's timeline estimates account for these variables, so the predicted delivery date is usually accurate. During Chinese New Year or major shopping festivals, all carriers experience delays, and SIYUNDA will update tracking to reflect extended delivery windows.
If you're sending packages internationally through SIYUNDA, Paxlo provides visibility at every stage. You'll see when the parcel leaves China, when it arrives at the destination country's entry point, and customs clearance status. SIYUNDA works with partners like DHL, FedEx, or local carriers in destination countries to complete final delivery, and Paxlo tracks through all handoffs.
Customs clearance can add 1-7 business days depending on the destination and contents. Paxlo keeps you informed of delays so you're not left guessing. If duties or taxes apply, the app may show additional charges, and Paxlo will notify you so you can prepare. For business shippers, this transparency helps with cash flow planning and customer communication.
Open Paxlo and paste your SIYUNDA tracking number into the search bar. The app recognizes the carrier automatically and pulls up the latest status. Your package appears in a timeline view showing each sorting facility or delivery attempt. You can enable notifications to get alerts when the status changes, so you know exactly when your package is arriving.
New SIYUNDA tracking numbers sometimes take 2-4 hours to activate in the system after pickup. If you just received the number, wait a few hours and check again. For older shipments stuck at the same location for 72+ hours, the package may be delayed due to weather, local network congestion, or a sorting error. Contact SIYUNDA customer service through their website or phone number (usually on your receipt) to ask for an investigation. Paxlo pulls data directly from SIYUNDA's servers, so if the tracking doesn't update in the app, it's not updating on SIYUNDA's end either.
Domestic SIYUNDA deliveries within China typically take 3-5 business days for standard service. Timing depends on distance, the current sorting network load, and weather. Urban deliveries often arrive faster, sometimes within 2 days. For international shipments, add 7-30 business days depending on the destination country. Paxlo shows you an estimated delivery date based on the current tracking progress, and this updates daily as your package moves. For time-sensitive items, always check Paxlo before ordering to see if SIYUNDA covers your location with standard timing.
International SIYUNDA parcels pause in tracking while at customs, which is normal and usually takes 24-48 hours. Paxlo shows a 'Customs Clearance' status so you know the package is being processed, not lost. If customs clearance takes longer than 5 business days, contact SIYUNDA's international department because the item may require additional documentation. For high-value goods or electronics, customs agents may need commercial invoices or proof of contents. Check your email for any customs notification or import duty letters while waiting.

Yes, SIYUNDA supports returns and refunds. If you need to return an item, contact the seller or SIYUNDA directly for a return shipping label. Enter the new return tracking number into Paxlo to monitor the package going back to the seller. Paxlo keeps both the original and return shipment in your history, so you have a complete record for warranty claims or disputes. Some sellers provide pre-paid return labels, others charge for return shipping, so clarify costs before initiating a return.
SIYUNDA is reliable for most packages, but for high-value items (over $500), you may want to consider SF Express or other premium carriers with additional insurance options. SIYUNDA does offer signature confirmation and basic tracking, which helps verify delivery. Always check SIYUNDA's coverage in your destination area before shipping, and consider purchasing shipping insurance if the item is valuable. Paxlo tracks every step, so you'll see if a delivery attempt was made or if the package arrived successfully.
