Dalian (Dayaowan)
North-east China's battery gateway at Dayaowan, with a small but growing lithium export flow, a local MSA that has named misdeclaration as its main problem, and both winter ice and spring fog.

From Dalian to Khalifa Bin Salman Port, cargo moves from Liaoning through Dalian's Dayaowan terminals, crosses an Arabian Sea passage where GNSS interference is reported off the Gulf of Oman, and is discharged at Khalifa Bin Salman Port, which takes every hazardous class but wants DG paperwork three days ahead.
On the Bahraini side a licensed clearing agent normally lodges the bill of entry ahead of arrival. Below are 5 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
North-east China's battery gateway at Dayaowan, with a small but growing lithium export flow, a local MSA that has named misdeclaration as its main problem, and both winter ice and spring fog.
An Arabian Sea passage and, for Gulf ports, the Strait of Hormuz, rated a SEVERE threat in September 2026, with GNSS jamming across the approaches.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Khalifa Bin Salman Port and at customs in Bahrain.
Sea fog is one of the main marine hazards of the Yellow and Bohai Seas according to the China Meteorological Administration, concentrated between April and July and with a serious effect on shipping. A vessel held at anchor by fog can arrive late enough to push a box beyond the sailing its documents name.
What Anxin does: In the fog season we avoid tight stuffing-to-cut-off gaps and keep the filing data ready to amend if the vessel changes.
According to Dayaowan MSA in April 2024, lithium battery cargo was often under-declared or misdeclared because the rules are complicated. It responded with a dedicated desk and hotline, priority for EV batteries, and AI-based document comparison intended to reduce container openings, which means any mismatch between the declaration and its supporting papers gets flagged.
What Anxin does: We reconcile the UN number, classification, packing group, quantity and SDS across every document before filing, which is exactly what an automated comparison will test.
The JMIC reports persistent GNSS jamming and spoofing across the Gulf of Oman, the Arabian Gulf and the Hormuz approaches, with AIS positions and speeds that do not add up; the Gulf of Oman and the Arabian Sea are rated MODERATE. Arrival estimates built on public ship tracking are less dependable on this leg.
What Anxin does: We rely on the carrier's own schedule updates rather than third-party AIS positions when we give you an arrival estimate for Khalifa Bin Salman Port.
At Khalifa Bin Salman Port every hazardous container is announced to APM Terminals planning with its MSDS and the manifest at least 72 hours before arrival; unlike classes 1, 5.2, 6.1, 6.2 and 7, class 9 needs no extra government approval.
What Anxin does: We send the carrier the SDS for each battery type with the DG declaration at booking, so the agent has it well before the 72-hour point for Khalifa Bin Salman Port.
In Bahrain the customs bill of entry comes before the import, not after discharge, and the usual route is a registered, licensed clearing agent working to Bahrain Customs procedures.
What Anxin does: We ask the importer which licensed clearing agent will lodge the bill of entry and send that agent the invoice, packing list and DG details as soon as the ship sails from Dalian.

Documents & compliance
Anxin reviews documents supplied by the shipper, manufacturer and importer; 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 Dalian filings, the carrier booking and the Bahrain 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 |
|---|---|---|---|
| Fog hold delays the vessel; filings need amending | Yellow Sea, Apr–Jul | Amendment-ready filing data | Anxin with the declarant |
| Declaration flagged by document comparison; container opened | Dayaowan | Cross-document reconciliation before filing | Anxin with the declarant |
| MSDS or manifest reaches planning too late | Khalifa Bin Salman Port | SDS sent with the booking | Agent |
| Bill of entry not ready when the box lands | Bahrain Customs | Clearing agent briefed when the ship sails | Importer / clearing agent |
Questions
The importer or its local agent completes the bill of entry before import; a registered, licensed clearing agent is recommended.
Between June and September India's southwest monsoon brings rough seas and squalls to the Arabian Sea that regularly disrupt port operations, so we check blocking and bracing on the stuffing photos and allow slack in the delivery plan.
Dayaowan MSA reported in 2024 that omissions and misdeclarations of lithium battery cargo were frequent because the rules are complex, and it uses AI document comparison. Consistent data across the declaration, SDS and packing documents is the main defence.
