Lithium batteries for Cleveland go out of Tianjin's Xingang terminals, where customs can supervise stuffing at the factory and the box goes straight to the ship on a booked slot. On the way they face a corridor into Atlantic Canada's waters, and they arrive at the port of Cleveland.
The US side starts with two filings due before loading and ends with a road leg that must carry a live emergency number. 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
- Factory-supervised loading
- Bohai Bay winter ice
- HTS code 8507.60
- ISF filer
- Supply-chain tracing file
Route profile
How Tianjin → Cleveland differs from other lanes
United States
Two filings before loading, a Section 301 line set by classification, UFLPA supply-chain questions and a 15-day General Order clock after discharge.
Where this route gets difficult
What to watch between Tianjin and Cleveland: 5 points
They run from the Tianjin terminal through the voyage to Cleveland and the United States import file.
- Origin port
Ice at the Haihe estuary in winter
Every winter the Bohai Sea ices over, and the Haihe estuary at Tianjin is one of the harder-hit areas. For 2021/22 the national marine forecast centre put the peak ice period between mid-January and mid-February, with floating ice about 5 nautical miles out in Bohai Bay. Ice and cold slow port work just as the Chinese New Year peak arrives.
What Anxin does: For January and February sailings from Tianjin we add slack between stuffing and the DG cut-off and confirm the vessel's berthing window with the carrier the week before loading.
- Sea corridor
North Atlantic winter storms peak in January
NOAA's Ocean Prediction Center has recorded hurricane-force mid-latitude storms in the North Atlantic from October to April, most often in January. The final leg to Cleveland crosses those waters.
What Anxin does: For winter sailings we check blocking and bracing on stuffing photos before sealing.
- Import country
Which 8507.60 line decides the Section 301 duty
For lithium-ion batteries entered from 1 January 2026 USTR set the Section 301 additional duty on HTSUS 8507.60.0020 (the non-EV line) at 25%, the level EV batteries under 8507.60.0010 reached in 2024. Other China-specific duties can be added and change at short notice, so the classification and the entry date both move the landed cost at Cleveland.
What Anxin does: We do not give duty rulings. We make sure the invoice describes chemistry, configuration and application precisely enough for the importer's customs broker to classify it, and we flag the entry date when a vessel's arrival could straddle a duty change.
- Import country
A US-only carton mark for SP188 shipments
Packages of UN3480 or UN3090 moving under IMDG special provision 188 skip the DG declaration at sea, yet 49 CFR 171.25(b)(3) still wants the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' mark or a Cargo Aircraft Only label on each one, and on packages of batteries with or in equipment over 5 kg net.
What Anxin does: When the shipper declares SP188 for a Cleveland booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
- Import country
UFLPA: lithium became a high-priority sector in August 2025
DHS added lithium to the Uyghur Forced Labor Prevention Act high-priority sectors in August 2025. By then CBP had stopped more than 16,700 shipments for UFLPA examination. For battery importers the practical effect is that CBP can ask where cells, cathode and lithium compounds came from, and a shipment waits while the importer answers.
What Anxin does: We tell the importer at quotation stage that supply-chain tracing may be requested, and keep manufacturer names and addresses consistent across invoice, packing list and ISF so the paper trail does not contradict itself.
Documents & compliance
What to have ready: Tianjin to Cleveland
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.
In Tianjin, before the box is loaded
- 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
Carrier and voyage
- In winter: ice capability of the vessel or feeder serving the port confirmed
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
- UN 38.3 test summary for every cell and battery type
For the importer in United States
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
- 24-hour emergency response number (and provider reference) for the US road leg
- Importer of record and the licensed customs broker who will file the entry
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
Risks on this route and who deals with them
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Ice or cold spell slows berthing in mid-winter | Bohai Bay, Jan–Feb | Slack between stuffing and cut-off; berthing window reconfirmed | Carrier, monitored by Anxin |
| Stack damage in a winter storm | North Atlantic, Oct–Apr | CINS stuffing checks | Packing site, checked by Anxin |
| UFLPA detention pending supply-chain evidence | CBP at entry | Importer prepares tracing documents before shipping; consistent manufacturer data on all documents | Importer |
| SP188 cartons without the US marking | Discharge and onward trucking | Marking or CAO label checked on carton photos before stuffing | Shipper, checked by Anxin |
Questions
Common questions on the Tianjin → Cleveland route
No. The carrier must also send its cargo declaration through AMS 24 hours before loading, and CBP will not issue the permit to unlade without it.
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.
Tianjin Customs offers a 'supervised factory loading, direct loading on port arrival' model: stuffing is supervised at the factory, the box enters the port in a booked slot and is loaded directly. Whether a given shipment can use it depends on the customs arrangement for the exporter and the port slot; we check both when you book.
