3CQ is the cross-border logistics platform presented on WJDrop, with operations centered on China and Brazil. The business is headquartered in Shenzhen and maintains a Brazil team and local fulfillment operation. Its verified logistics services focus on moving ecommerce goods from China to Brazil and handling fulfillment within Brazil, while references to wider Latin American coverage should not be treated as proof that 3CQ operates its own delivery network in every destination country.
For China-to-Brazil shipping, 3CQ publishes a Brazil small-package service covering air transport, customs clearance and delivery. It also offers a large-cargo sea-freight service for bulk shipments, including first-leg ocean transport, bonded customs clearance and truck delivery across Brazil. The company's Brazil operation also uses local warehousing and fast distribution, which is important when interpreting delivery-time claims because a parcel dispatched from inventory already stored in Brazil follows a different journey from one starting in China.
3CQ has its own integrated logistics tracking platform. Its official documentation says the system synchronizes tracking data for Brazil small parcels, large sea-freight shipments and Brazil Post data, and supports multilingual searches, exception alerts and API callbacks. Brazil Post, J&T Express Brazil and other logistics companies are also identified as partners, so a shipment can involve a handoff rather than remaining entirely within a 3CQ-operated delivery network.
How to track a 3CQ package with 4Tracking
Copy the complete tracking number from the merchant, sender, shipping confirmation or parcel documentation. Enter that number on the 3CQ page at 4Tracking and submit the tracking request. When tracking information is available, you can review the shipment events associated with the number and follow the sequence of processing, transport, customs or delivery updates provided through the available tracking sources.
Use the event history to understand the parcel's progress rather than treating it as a continuous live location. A China-to-Brazil shipment can move through origin handling, international transportation, Brazilian customs clearance and final delivery, and there may be gaps between visible events. A lack of a new scan does not by itself identify where the parcel is physically located.
3CQ's own website also provides a logistics inquiry field where users can enter a waybill number. The carrier describes its system as providing shipment-to-delivery visibility and says its integrated platform synchronizes information from its Brazil small-package and sea-freight channels as well as Brazil Post. Those capabilities describe the official 3CQ system; 4Tracking should be used to view the shipment events it has available without assuming that carrier-side exception alerts, API functions or every internal event are reproduced.
If a tracking number returns no information, compare it with the original shipping notice before contacting support. Make sure it is the logistics waybill number rather than a shop order number, payment reference or product identifier. If the number is correct but remains unrecognized, ask the sender to confirm that the parcel has entered the 3CQ shipping process and whether a separate number was issued for a Brazilian delivery partner.
3CQ tracking-number formats
3CQ's public documentation does not specify a standard tracking-number length, prefix, suffix or combination of letters and digits. Its official tracker asks users to enter a waybill number, but that does not establish one universal format for small parcels, sea freight and shipments that later use a partner carrier.
Copy the complete number exactly as it was issued. Keep all letters, digits and leading zeros, and do not modify it to resemble a Correios or another carrier's format. If the shipping documents show both a 3CQ waybill and a later partner tracking number, use the identifier that corresponds to the stage you are trying to check.
Delivery times for 3CQ shipments
For its Brazil small-package line, 3CQ publishes an end-to-end delivery time of 5–10 days. This service is described as a China-to-Brazil B2C solution covering air transport, customs clearance and delivery, so the 5–10-day figure is the most relevant published estimate for a qualifying small parcel on that service. It should not be applied automatically to sea freight, local Brazilian fulfillment or a shipment booked under a different arrangement.
The main 3CQ page also advertises 48-hour delivery in Brazil. That figure should be kept separate from the published 5–10-day end-to-end small-package timeframe. The company's Brazil operation uses local warehousing and rapid distribution, so a package already stocked and fulfilled in Brazil can have a much shorter delivery stage than a parcel that first has to travel from China. A recipient should use the service and origin shown for the actual order rather than assuming every China-to-Brazil package qualifies for 48-hour delivery.
Large cargo follows a different process. 3CQ's Brazil sea-freight service is intended for bulk, heavy or replenishment shipments and combines first-leg sea transport, bonded customs clearance and Brazilian truck delivery. The official service description does not publish a single end-to-end number of days for this option, so the booking or sender should provide the relevant schedule for an individual sea shipment.
Customs clearance is part of the journey, not the same as total transit time. 3CQ states that it provides Brazil PRC customs-clearance capability, but a parcel that has reached or completed customs may still need sorting, transportation and final delivery. When tracking appears to remain at a customs stage, compare the shipment with the service-specific estimate before treating the clearance event as a delivery deadline.
How to contact 3CQ about shipment issues
The official WJDrop contact page lists the email address yihuixue@gmail.com and the telephone number 13823379449. It also lists an office at Room 703, Building 1, Aerospace Building, 51 Gaoxin South 9th Road, Yuehai Subdistrict, Nanshan District, Shenzhen, China. The website additionally presents a WhatsApp consultation option and states that local Portuguese-language customer service is available around the clock.
Before contacting support about a parcel, prepare the full tracking number, sender or merchant name, shipping date if known, origin and Brazilian destination, and the date and wording of the last visible tracking event. If the parcel has already been handed to a Brazilian partner, include any second tracking number or carrier name shown in the shipment history. This helps support distinguish an international 3CQ movement from the final local delivery stage.
For an order bought from an online seller, contacting the merchant can also be useful when the shipping number is missing or the booked service is unclear. The sender can confirm whether the parcel uses the 3CQ Brazil small-package line, local Brazilian fulfillment or another logistics arrangement, which determines which delivery estimate and tracking reference are relevant.
Frequently asked questions about 3CQ package tracking issues
Why does my 3CQ tracking number show no shipment events?
First confirm that you entered the logistics waybill rather than the shop's order number. If the number is correct, ask the sender whether the parcel has been handed to 3CQ yet or whether another tracking number applies.
Does every 3CQ package use the same tracking-number format?
No common public format is specified. Copy the complete identifier from the sender or shipping paperwork instead of trying to reconstruct it from a presumed prefix or number of digits.
Does the 48-hour delivery claim mean my parcel from China will reach Brazil in two days?
Do not use it that way. 3CQ separately publishes a 5–10-day end-to-end timeframe for its Brazil small-package line, while its Brazil operation also uses local warehousing and rapid distribution that can support much shorter domestic fulfillment.
How long does the 3CQ Brazil small-package service take?
3CQ publishes a 5–10-day end-to-end timeframe for its Brazil small-package service covering air transport, customs clearance and delivery. Treat it as the estimate for that service, not as a guarantee for every shipment or for sea freight.
Why might my package start showing Brazil Post or another Brazilian carrier?
3CQ works with Brazilian logistics partners and its tracking platform synchronizes Brazil Post data. A partner-carrier event can therefore represent a handoff for the local delivery stage rather than a new international shipment.
Does customs clearance mean my 3CQ package is ready for delivery?
Not necessarily. Customs is only one stage of the China-to-Brazil journey, and sorting, domestic transportation or final delivery may still follow after clearance.
What should I provide when contacting 3CQ about a delayed parcel?
Prepare the full tracking number, sender or merchant, shipment date, origin and destination, and the most recent tracking event with its date. Include any Brazilian partner tracking number if one has appeared after the handoff.
