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.

This route runs from the Pearl River Delta via Nansha, then follows a long voyage ending in the North Atlantic or the Gulf of St Lawrence; at the far end is the port of Cleveland.
The United States applies Section 301 and UFLPA scrutiny to Chinese lithium batteries and wants its manifest data before loading. 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
- Dongguan–Nansha one-box
- Typhoon season Jun–Oct
- HTS code 8507.60
- ISF filer
- Supply-chain tracing file
Route profile
What sets Guangzhou → Cleveland apart
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
5 points to plan for on the Guangzhou → Cleveland route
They run from the Guangzhou terminal through the voyage to Cleveland and the United States import file.
- Origin port
One-box inspection now reaches Nansha
Since 22 September 2026 Guangzhou MSA accepts Dongguan MSA's factory inspection for boxes loading at Nansha and re-inspects only when necessary. The first container was stuffed in Dongguan that day and left Nansha for Singapore on 24 September. Because the arrangement is new at Nansha, the factory record needs to be correct the first time.
What Anxin does: We ask at booking whether your Dongguan factory can use the Nansha one-box arrangement and make sure the stuffing photos, packing certificate and DG declaration match, because a mismatch is the 'necessary' case that brings the second inspection back.
- Sea corridor
The St Lawrence icebreaking season, December to May
From December to May the Canadian Coast Guard breaks ice on the Gulf of St Lawrence and the river, and ships must clear with ECAREG CANADA 24 hours before entering, giving their ice class. Whether a winter sailing reaches Cleveland on time depends on the ship's ice capability and icebreaker routing.
What Anxin does: For December–May arrivals we ask the carrier whether the vessel or feeder serving Cleveland is ice-classed and build slack into delivery.
- Import country
SP188 packages need an extra US marking
Small cells and batteries shipped under IMDG special provision 188 do not need a dangerous goods declaration at sea, but 49 CFR 171.25(b)(3) adds a US condition: each package of UN3480 or UN3090 must carry the 'FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT' marking or a Cargo Aircraft Only label, and so must packages of batteries with or in equipment above 5 kg net. Cartons printed for other markets often lack it.
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
ISF closes 24 hours before loading in Guangzhou
The Importer Security Filing must reach CBP no later than 24 hours before the container is laden aboard the vessel abroad. CBP's liquidated damages guidelines provide for a claim per violation for late, inaccurate or incomplete filings. Two of the data elements, the container stuffing location and the consolidator, only exist once the box is packed.
What Anxin does: We send the importer's ISF filer the stuffing location, consolidator and manufacturer details as soon as the container is packed in Guangzhou, ahead of the vessel's loading window.
- Import country
Demurrage and detention invoices must follow FMC rules
Battery containers held for DG checks or paperwork can run up demurrage and detention at Cleveland. Under the FMC's billing rule, in force since May 2024, carriers and terminals must invoice within 30 days with accurate, complete information, or the charge is not payable, and the billed party has at least 30 days to ask for a waiver or refund. A 2025 court ruling set aside only the section on who may be billed.
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.
Documents & compliance
What to have ready: Guangzhou to Cleveland
Anxin reviews documents supplied by the shipper, manufacturer and importer; it does not issue test reports, safety data sheets or import certificates.
Before loading in Guangzhou
- 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
- Condition statement: new, used, damaged/defective (SP376) or for recycling (SP377)
- SP188 cartons: US 'forbidden aboard passenger aircraft' marking or CAO label
For import into United States
- ISF filer named; stuffing location and consolidator sent right after packing
- HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Guangzhou filings, the booking with the carrier and the documents for United States before the booking is confirmed, so that a mismatch is fixed at origin rather than discovered at Cleveland.
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 |
|---|---|---|---|
| Second inspection at Nansha because factory records are incomplete | Dongguan factory → Nansha | Photos, packing certificate and declaration matched before trucking | Anxin |
| Ice delays arrival or limits which vessels can call | Gulf of St Lawrence, Dec–May | Ice-classed vessel confirmed; slack in delivery | Carrier |
| Late or inaccurate ISF | Before loading abroad | Stuffing and consolidator data sent to the ISF filer immediately after packing | Anxin with the ISF filer |
| 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 Guangzhou → 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.
Both now have a one-box arrangement with Dongguan MSA: Yantian since May 2026 and Nansha since 22 September 2026, so a container inspected at the factory need not be reopened at the terminal unless necessary. The choice then comes down to the carrier's service to your destination and the cut-offs; we compare both when you book.
