Asia – Southeast Asian seas
No canal on this route, but two seasons to plan around: typhoons in summer and autumn and the north-east monsoon from November to March.

From Shenzhen to Panjang, cargo moves out of Shenzhen's Yantian and Shekou terminals, crosses Southeast Asian waters, with their typhoon and monsoon seasons, and is discharged at the port of Panjang.
In Indonesia the carrier files the manifest before unloading and primary cells need SNI certification. The 5 points below are particular to this lane; each comes with what we do and the paperwork it touches.
What we need to start
- Typhoon season Jun–Oct
- Yantian / Shekou export
- Used-battery approval
- 24-hour arrival notice
- SNI for primary cells

Where this route gets difficult
5 points to plan for on the Shenzhen → Panjang route
In the order the cargo meets them: at the loading port, at sea, at Panjang and at customs in Indonesia.
- Origin port
Cut-offs in Shenzhen's typhoon weeks
June to October is the regional tropical cyclone season according to the Hong Kong Observatory, peaking July to September. Because DG boxes need approved MSA filings and a signed packing certificate before loading, a gate closure or rolled vessel in those weeks can move the entire document chain to another sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
- Origin port
Dongguan's packaging certificate data is shared
Dongguan, home to more than 500 battery companies, supplies much of the cargo leaving Shenzhen. Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data, described as a first in China, and act jointly against concealed and false declarations; the one-box route to Yantian, 409 containers by then, relies on the same record.
What Anxin does: We compare the packaging certificate with the MSA cargo report (UN number, packaging code, number of packages) before either goes in, so the shared data shows no gap.
- Sea corridor
A Singapore relay needs its own DG declaration
If the container for Panjang relays in Singapore, the Port Master must receive a dangerous goods declaration at least 12 hours before the vessel arrives, for DG in transit as well as for DG discharged or loaded. At PSA terminals it goes through PORTNET, and storage of DG at the terminal needs the operator's approval.
What Anxin does: We give the carrier the UN number, class, packing group and packages at booking, so the Singapore declaration for the relay can be filed on time by the carrier's agent.
- Import country
Primary cells need SNI certification and marking
Since 20 May 2025 primary batteries sold in Indonesia must be SNI-certified and marked (Permenperin 69/2024). A consignment for Panjang 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.
- Import country
Check whether Indonesian-language labels are required
Permendag 25/2021 lists goods that must carry Indonesian-language labels when sold in Indonesia. Whether a battery product going to Panjang 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 Shenzhen.
Documents & compliance
What to have ready: Shenzhen to Panjang
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.
In Shenzhen, before the box is loaded
- Confirmation from the carrier of the DG cut-off at Yantian or Shekou, rechecked in typhoon weeks
- Customs packaging use-appraisal result for the dangerous goods packaging (with the maker's performance appraisal)
- Container packing certificate signed by a certified packing inspector after supervised stuffing
- Transport-condition classification report where applicable
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
For the carrier and the voyage
- DG acceptance confirmed for a back-up vessel in typhoon months
- UN 38.3 test summary for every cell and battery type
- Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)
For the importer in Indonesia
- SNI certificate for any primary cells in the shipment
- Import approval and surveyor report for used batteries
Before you book
Send the file once, complete
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 Shenzhen 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
What could go wrong from Shenzhen to Panjang, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Packaging certificate and MSA filing disagree; shipment flagged | Dongguan → Yantian | Line-by-line comparison before filing | Anxin with the declarant |
Questions
Common questions on the Shenzhen → Panjang route
Only with an import approval, an API-P business number and a surveyor's report through INSW.
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.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
