Lithium batteries for Belawan go through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules. On the way they face the monsoon-driven seas of Southeast Asia, and they arrive at the port of Belawan.
On the Indonesian side the importer's approvals matter: SNI for primary cells and an import approval for used batteries. Below are 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
Route profile
Yangshan and Waigaoqiao exports under Shanghai MSA's photo-verified packing system, where a mismatch between photos and EDI data keeps a DG box off the ship.
Typhoons and the winter monsoon set the pace on this short Southeast Asian route; smaller ports are often reached through a hub.


Where this route gets difficult
Loading port first, then the sea leg, then Belawan and the Indonesia market.
Shanghai's electronic packing certificate goes out by EDI only after the inspector has uploaded before, during and after stuffing photos through the MSA's remote system, with face recognition and phone location switched on. Missing, late or off-site photos, or photos that do not match the EDI cargo data, stop the container from loading. Stuffing sites outside Shanghai need registration with Shanghai MSA.
What Anxin does: We confirm that the stuffing site (including factory sites in Jiangsu or Zhejiang) is registered for Shanghai's remote system, and we check the photo upload against the EDI data before the packing certificate is sent.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration from the stuffing company, but places the burden on the shipper: the batteries must meet the UN tests and be protected against damage, short circuit and accidental activation, and MSA runs spot checks during and after the process, with proof to be produced on request.
What Anxin does: We keep a file per container (UN38.3 summary, SDS, packing photos, terminal protection details) so that proof can be produced the same day if Shanghai MSA asks for it after sailing.
Routes from northern China to Belawan go through the Taiwan Strait, whose funnel effect makes winds 1-2 Beaufort levels stronger than outside. In winter and spring the north-east monsoon brings force 7 or more on about two-thirds of days, which is hard on a load that has not been braced.
What Anxin does: We ask for blocking and bracing photos before the container is closed in Shanghai, checked against the CINS stuffing guidance for lithium batteries.
Under PMK 158 the carrier notifies arrival 24 hours ahead and files the inward manifest before unloading. For a battery container from Shanghai, the manifest's description has to match the DG papers exactly.
What Anxin does: We give the carrier final cargo data, HS code and UN number before sailing from Shanghai, so the Indonesian manifest matches the DG declaration.
Since 20 May 2025 primary batteries sold in Indonesia must be SNI-certified and marked (Permenperin 69/2024). A consignment for Belawan that mixes lithium-ion packs with primary cells needs the certificate for the latter.
What Anxin does: When a shipment includes primary cells, we ask the importer for the SNI certificate and check the marking on carton photos before loading.
Permendag 25/2021 lists goods that must carry Indonesian-language labels when sold in Indonesia. Whether a battery product going to Belawan is on the list should be checked by the importer before the retail packaging is printed.
What Anxin does: For retail-packed goods we ask the importer to confirm the labelling requirement before production is packed in Shanghai.

Documents & compliance
These documents come from the shipper, the manufacturer and the importer. Anxin checks them against each other; it does not issue test reports, safety data sheets or import certificates.

Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Shanghai filings, the carrier booking and the Indonesia import file. We check the three against each other before the booking is confirmed.
Carriers we book with
Our booking panel; availability on this lane and acceptance of the declared UN numbers are confirmed for each booking. It does not mean that a listed carrier runs a direct service on this route. Carrier choice depends on the trade lane, cargo classification and each carrier's dangerous-goods acceptance at booking. The final carrier is confirmed on the booking.
Risk & mitigation
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Container refused for loading: photos late, off-site or not matching EDI data | Yangshan / Waigaoqiao | Photo upload checked against EDI data before the certificate is sent | Packing inspector, checked by Anxin |
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Container held for a manifest mismatch | Indonesian port of discharge | Manifest data checked against the DG declaration | Carrier, with data from Anxin |
Questions
Primary batteries have needed SNI certification and marking since 20 May 2025. Lithium-ion packs should be checked by the importer against the current SNI list.
From about November to March the north-east monsoon brings rough seas in the southern South China Sea. It rarely stops sailings, but it tests the stowage, so bracing matters more.
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration issued by the stuffing company. Either way, the shipper remains responsible and must provide proof if MSA spot-checks.
