Asia – Atlantic Canada, the St Lawrence and the North Atlantic
The last leg crosses the North Atlantic or enters the Gulf of St Lawrence, with an icebreaking season from December to May and hurricane-force winter storms peaking in January.

From Tianjin to Milwaukee, cargo moves out of Tianjin's Xingang terminals, crosses a long voyage ending in the North Atlantic or the Gulf of St Lawrence, and is discharged at the port of Milwaukee.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. 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
- Factory-supervised loading
- Bohai Bay winter ice
- HTS code 8507.60
- ISF filer
- Supply-chain tracing file
Route profile
The Tianjin → Milwaukee route in brief
United States
A duty line set by the exact 8507.60 code, lithium supply-chain questions under UFLPA, and ISF and AMS filings that are due before the box is loaded.
Where this route gets difficult
5 points to plan for on the Tianjin → Milwaukee route
Loading port first, then the sea leg, then Milwaukee and the United States market.
- Origin port
Document review time at Tianjin and the cut-off
In July 2026 Tianjin MSA acknowledged that long document reviews under its traditional model often caused firms to miss the vessel's document cut-off, leaving cargo in port for another ship. The new appointment-based green channel, more than 50% faster with a fixed document list, is for new-energy-vehicle cargo; battery shipments should not count on it.
What Anxin does: We submit the cargo report with the full document set (safe-carriage declaration, SDS, packing certificate, packaging certificate) days before the cut-off rather than on the day, and treat any MSA query as same-day work.
- Sea corridor
Ice in the Gulf of St Lawrence, December to May
The Canadian Coast Guard's icebreaking season on the Gulf of St Lawrence and the St Lawrence River typically runs from December to May, and ships must clear with ECAREG CANADA 24 hours before entering, declaring their ice class. Winter sailings to Milwaukee depend on the vessel's ice capability and on icebreaker routing.
What Anxin does: For December–May arrivals we ask the carrier whether the vessel or feeder serving Milwaukee is ice-classed and build slack into delivery.
- Import country
The FMC's 30-day rules on demurrage and detention bills
If a battery container waits at Milwaukee, the demurrage or detention invoice has to arrive within 30 days and carry accurate and sufficient information, or the charge is not owed (46 CFR part 541). The billed party then has at least 30 days to dispute it; in 2025 the D.C. Circuit struck down only the rule on who may be invoiced.
What Anxin does: We keep the dates of discharge, availability and any DG hold for each container, so the importer can check invoices against them and dispute charges inside the FMC time limits.
- Import country
The emergency response number has to be answered live
US rules want a numeric emergency response telephone number on the shipping paper for battery cargo that leaves Milwaukee by road, monitored for as long as the goods are in transport and answered by a person with the emergency information for UN3480 or UN3090. A call-back service fails the test (49 CFR 172.604); only the IMDG waiver for cargo that never touches a public highway avoids it.
What Anxin does: Before sailing we confirm who provides the 24-hour number for the US leg, usually the importer's emergency response provider, and put it with the contract reference on the DG documents we send to the trucker.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Milwaukee without a release permit may stay at the terminal only until the 15th calendar day. The carrier must then notify CBP and a bonded general order warehouse, which moves and stores the goods at the consignee's risk and expense (19 CFR 4.37). Not every general order warehouse can take Class 9 battery cargo, and where specialized storage is missing the port director decides where it goes.
What Anxin does: We check with the importer's broker that the entry can be filed before arrival at Milwaukee, and chase any missing invoice or HTS detail while the ship is still at sea.
Documents & compliance
Documents to line up for Tianjin → Milwaukee
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.
At the Tianjin end
- Load plan showing even weight distribution (no more than 60% of the cargo weight in either half of the container length)
- 'Made in China' marking on articles or containers checked on photos
- Safety data sheet and dangerous goods safe-carriage declaration for the MSA cargo report
- 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
For the carrier and the voyage
- In winter: ice capability of the vessel or feeder serving the port confirmed
- Lithium battery mark (SP188 cargo) or class 9 labels and placards
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
For the importer in United States
- 24-hour emergency response number (and provider reference) for the US road leg
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
Before you book
One consistent file
A document that is present but inconsistent holds a booking as surely as a missing one: the UN number, model name or carton count reads differently in the Tianjin export filings, the carrier booking and the United States import papers. We compare all three before confirming space.
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 table for Tianjin → Milwaukee
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Document review runs past the vessel cut-off; cargo re-allocated to a later ship | Tianjin MSA review | Complete document set filed days before cut-off | Anxin with the declarant |
| Ice delays arrival or limits which vessels can call | Gulf of St Lawrence, Dec–May | Ice-classed vessel confirmed; slack in delivery | Carrier |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Common questions on the Tianjin → Milwaukee route
Yes. Under 49 CFR 171.25(b)(3), SP188 packages of UN3480 or UN3090 need the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so do packages of batteries packed with or contained in equipment above 5 kg net. We check for it on carton photos before stuffing.
Rarely. The Seaway's maximum draft in the Montreal–Lake Ontario section is 8.00 m and it closes in winter (target 5 January 2027 for the 2026 season), so containers usually leave the ocean vessel at a coastal port and continue by smaller ship, rail or truck.
The green channel Tianjin MSA announced in July 2026 is for new-energy-vehicle cargo. For battery containers we plan on the normal review and file early, because Tianjin MSA has said long reviews under the traditional model often cost firms their vessel cut-off.
