Shanghai (Yangshan / Waigaoqiao)
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.
Northeast Asia · sea freight from Shanghai
Shanghai to Tokyo
East China Sea
From Shanghai to Tokyo, cargo moves through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules, crosses an intra-Asia passage with no canal or chokepoint, and is discharged at the port of Tokyo.
In Japan the importer carries the PSE duties and the port captain controls dangerous goods in port. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.
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.
Japan wants the cargo data before the ship sails and a notified PSE supplier behind the batteries.


Where this route gets difficult
In the order the cargo meets them: at the loading port, at sea, at Tokyo and at customs in Japan.
Shanghai MSA's Notice No. 4 of 2024 lets the shipper use either an inspector-signed packing certificate or a packing declaration from the stuffing company, but the responsibility stays with the shipper: UN-tested batteries, protected against damage, short circuit and accidental activation. MSA spot-checks during and after the process and can ask for proof.
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.
The Japan Meteorological Agency counts an average of 25.1 typhoons a year in the western North Pacific, with the most in August and September. On a short route the voyage is quick, but a storm can close the loading or discharge port for days, and the DG filings follow the box to whichever vessel it ends up on.
What Anxin does: For July–October sailings to Tokyo we confirm the DG cut-off a week ahead and refile promptly if the vessel changes.
Japan's Advance Filing Rules require the carrier to file master B/L data and the NVOCC to file house B/L data in NACCS no later than 24 hours before the ship leaves the loading port, relaxed to 'before departure' on certain short routes. Customs can issue a do-not-unload notice for high-risk cargo bound for Tokyo, and missing or false filings are penalised.
What Anxin does: We send the house B/L data, with the UN number and a precise battery description, to whoever files it well before the cut-off in Shanghai.
Under Japan's Port Regulations Act a ship carrying dangerous goods of the categories MLIT lists must seek the port captain's directions outside the port limits before entering a specified port such as Tokyo, anchor or moor where the captain says, and get permission to load, transship or unload them. The ship's side needs accurate DG data well before arrival.
What Anxin does: We confirm the DG class, UN number and quantities on the carrier's manifest before sailing, so the ship's agent has what it needs for the port captain.
METI's FAQ is explicit that a company which only handles customs procedures as an agent is not the importer under the Act. Inspection records must also be kept for three years, so the obligation stays with the business that brings the batteries into Japan through Tokyo.
What Anxin does: We make sure the invoice and the import declaration name the same Japanese company that holds the PSE notification, not only the broker.

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 Shanghai filings, the carrier booking and the Japan 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 |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Typhoon closes a port; box moves to another vessel | Western North Pacific, Jul–Oct | DG cut-off confirmed; prompt refiling | Anxin with the declarant |
| Do-not-unload notice after missing or inaccurate advance data | Japanese port of discharge | House B/L data sent early and checked | NVOCC / carrier, with data from Anxin |
Questions
In a specified port the Port Regulations Act requires the port captain's permission to load or unload dangerous goods of the listed categories, and directions before entering.
Typhoons occur all year in the western North Pacific, but most in August and September: the Japan Meteorological Agency's 1991–2020 averages are 5.7 and 5.0 typhoons in those months.
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.
