This guide explains the current status of Phase 3 and the Road Cargo System (ROCARS) replacement, then turns the change into practical steps for DTC operations. The first Phase 3 batch went live on 1 May 2026, replacing ROCARS for advance cargo information (road). Other Phase 3 services are planned in later batches. The important task for sellers is not to assume that every shipment process has changed at once, but to confirm who submits what, when the submission happens and how shipment data stays consistent from order to truck.
What Phase 3 changes for Hong Kong road cargo
The TSW is a government electronic platform for submitting trade documents and cargo information. Phase 3 is being rolled out in batches. Its planned scope includes import and export declarations, advance cargo information for different transport modes, cargo manifests and reports, and applications such as Certificates of Origin and Dutiable Commodities Permits. The first batch, launched on 1 May 2026, covered advance cargo information for road cargo and replaced ROCARS for that service. Hong Kong Customs says existing ROCARS user data was migrated and users did not need to re-register to use the first-batch service.
That distinction matters for day-to-day planning. The road-cargo submission service has moved to TSW, but the other Phase 3 services are separate future batches, not a reason to assume every customs document or mode of transport already uses the same new workflow. The government has indicated that the second and third batches are targeted to roll out from mid-2027. Check current official TSW notices and confirm with your customs or freight partners before changing other processes.
For a DTC seller, the impact depends on how goods move. If inventory is trucked across a land boundary into or out of Hong Kong, the road cargo information and its association with the relevant shipment or truck movement need to be handled through the current TSW service. If your goods arrive by air or sea and are later moved by road, ask partners exactly where the road leg begins and who is responsible for its advance information. A shipment’s route and handovers—not just the customer’s destination—determine which operational step needs attention.
Map the journey before assigning responsibility
Start by drawing the route for each common shipping pattern. For example, a Hong Kong seller may hold stock at a local fulfilment centre, consolidate orders, send cartons by road across a land boundary, and inject parcels into a destination-country delivery network. Another seller may bring replenishment stock into Hong Kong by air, store it locally, then use a cross-boundary truck for a later leg. These are different flows, and different partners may control the relevant shipment information at each stage.
For every flow, record the party that creates the cargo record, the party that submits advance cargo information, the party that arranges any required bundling, and the person who checks that the submission is accepted before dispatch. Do not assume that the fulfilment warehouse or your freight forwarder is responsible simply because they arrange transport. Put the agreed division of work in writing, including cut-off times, escalation contacts and what happens when order details change after a submission.
This is especially useful when one seller account feeds multiple warehouses, carriers or forwarders. A clear responsibility map prevents duplicated submissions and gaps where each partner expects another party to act. It also helps customer service understand whether a delay is caused by order processing, cargo-data preparation, a truck departure or a later carrier handover.
Make your cargo data accurate and reusable
Build a reliable source of shipment data before it reaches a freight partner. Useful fields to review include the shipper and consignee details, the cargo description, package or carton count, gross weight, shipment references and the identifiers your transport partner needs to associate cargo with a vehicle or movement. The exact fields and validation rules depend on the applicable service and your role in the movement, so use the current TSW guidance and your authorised submitter’s requirements rather than relying on an old ROCARS checklist.
Descriptions should be specific enough to identify the goods in ordinary trade terms. “Goods” or “online order” is not a helpful substitute for an accurate description such as apparel, phone cases or skincare products, where that reflects the actual contents. Keep product and shipment data aligned across your order system, packing list, commercial invoice and partner booking. Where products are controlled or require permits, do not infer that a road-cargo submission replaces those separate obligations; confirm the applicable requirements for the goods and route.
Use stable shipment references and define how partners will report corrections. If the number of cartons changes during packing, or an order is split between two consignments, the final data should reflect the physical shipment that will move. Agree whether your warehouse sends a final file, updates a shared system or confirms data through another channel, and specify who checks it against the booking before the submission deadline.
Coordinate fulfilment and freight partners around cut-offs
The system change is a good reason to review the handoff between fulfilment and transport. Ask each partner whether they submit through the TSW portal or an approved system-to-system connection, which account or authorisation they use, and what information they need from you. Also ask how they confirm acceptance, how quickly they notify you of a rejection or missing field, and how they handle amendments. Get answers from the party doing the submission; a general assurance that “customs is covered” may not explain who owns the data or the cut-off.
Then work backwards from the truck’s planned departure. Set internal deadlines for order release, picking, packing, final carton count, data transfer and submission confirmation. Allow time to resolve a mismatch before the vehicle is ready to leave. For a promotion or a seasonal peak, test the process on a normal shipment first and agree a named escalation contact for late changes. A workable process is one where the team can see that the cargo information is ready—not one where everyone assumes someone else has submitted it.
If a shipment is urgent, changing its route or splitting it may affect who submits information and what references need to match. Make sure the fulfilment team and forwarder agree on the revised plan before the cargo is loaded. A simple shared checklist can capture order or shipment reference, final package count, responsible submitter, submission status, vehicle or movement reference as required by the partner, and release status.
Adapt Hong Kong hub workflows without overhauling everything
Treat the first-batch transition as an operational update to the road leg, not a reason to rebuild your entire ecommerce stack. Review standard operating procedures, partner instructions, staff training and any internal dashboard that still names ROCARS as the submission route. Replace outdated references with the current TSW process, and make it clear that future Phase 3 batches may bring additional changes. Staff should know where to check current official instructions and whom to contact when a system or data question arises.
For sellers managing orders across channels, the useful improvement is often better visibility. Track whether cargo data is prepared, submitted and confirmed alongside the normal fulfilment milestones. If you use a shipping platform such as ShipAny to manage order and carrier workflows, keep shipment references and status updates consistent between the platform and the freight partner’s process. The platform can help organise shipping operations, but it does not remove the need to confirm which party is legally or operationally responsible for the required government submission.
Keep a basic exception plan for system downtime, rejected data, late packing changes and missed cut-offs. The official launch notice stated that land-boundary cargo clearance services remained normal during the 1 May 2026 cutover, while advising traders with cross-boundary transport during the cutover to submit information and complete bundling arrangements well in advance. For future changes or disruptions, check official notices and follow your carrier’s current instructions rather than assuming the launch-period arrangements apply indefinitely.
Prepare now for later Phase 3 batches
The broader Phase 3 programme is intended to bring more trade documents and cargo information into the TSW in batches. Official information lists areas including declarations, cargo information for different transport modes, manifests and reports, and specified applications. The government has targeted the second and third batches from mid-2027; treat that as a planning target, not a confirmed launch date for every service. Monitor official announcements for specific service scope, launch dates, transition arrangements and technical instructions.
In the meantime, reduce avoidable data rework. Maintain a single, controlled product and shipment data source; document which team owns each field; and retain records of what was sent to each partner and when. Ask your forwarder or customs service provider to alert you when a change affects your workflow, and schedule a review before a new batch goes live. For businesses shipping through Hong Kong hubs, this measured approach makes it easier to add a new submission step without disrupting order fulfilment or customer promises.
FAQ
Has TSW Phase 3 already replaced ROCARS for road cargo?
Yes. Hong Kong’s first batch of TSW Phase 3 services launched on 1 May 2026 and replaced ROCARS for submitting advance cargo information for road cargo. Hong Kong Customs said ROCARS user data was migrated and existing users did not need to re-register. Confirm current access and submission arrangements with your authorised submitter.
Does the ROCARS replacement mean all Hong Kong customs processes now use TSW?
No. The first Phase 3 batch covered the advance cargo information (road) service previously provided by ROCARS. Other Phase 3 services, including additional declarations and cargo information, are being rolled out in later batches. Check current official TSW notices before changing processes for air, sea or other trade documents.
Who should submit road cargo information for my DTC shipments?
That depends on the shipment arrangement and the parties involved. Confirm in writing whether you, your freight forwarder, carrier or another authorised agent prepares and submits the information, and who handles corrections and confirmation. Agree on data requirements, cut-offs and escalation contacts before dispatch.
What should a Hong Kong seller do before a cross-boundary truck leaves?
Ensure the responsible partner has accurate final cargo details, has completed the required submission and any applicable bundling arrangements, and has confirmed the status before the agreed cut-off. Reconcile the shipment information with the packed cargo and booking, especially if cartons or consignment details changed. Follow current TSW instructions and your transport partner’s process.
Conclusion
For DTC sellers shipping through Hong Kong, the practical change is clear: the road-cargo advance information service has moved from ROCARS to TSW, while wider Phase 3 services are still being introduced in batches. The best preparation is to map each route, name the responsible submitter, and keep shipment data accurate from fulfilment through truck departure.
Review your partner handoffs now, then keep watching official TSW updates as later services are announced. A little clarity around data ownership and cut-offs can help keep cross-border fulfilment predictable.
