This route runs from factories around the Pearl River Delta through Yantian or Shekou, then follows the Pacific, the Panama Canal and the Caribbean; at the far end is the port of St. Augustine.
St. Augustine means US customs filings that are due while the container is still in Shenzhen, and a supply chain CBP may ask to see. This page sets out 5 points specific to this route, how Anxin handles each one and which documents to prepare.

Where this route gets difficult
What to watch between Shenzhen and St. Augustine: 5 points
They run from the Shenzhen terminal through the voyage to St. Augustine and the United States import file.
- Origin port
Typhoon season squeezes Shenzhen cut-offs
The Hong Kong Observatory puts the regional tropical cyclone season from June to October, busiest July to September. DG containers need their MSA filings approved and a signed packing certificate before loading, so a closed gate or a rolled vessel in typhoon weeks can push the whole document chain to a new sailing.
What Anxin does: From June to October we build slack into the stuffing date, confirm the DG cut-off with the carrier the week before loading, and resubmit filings promptly if the vessel changes.
- Sea corridor
Panama's draft limit depends on the lake
The Panama Canal Authority sets the maximum draft in the Neopanamax locks according to Gatun Lake levels. In September 2026 it postponed a planned cut from 14.63 m to 14.48 m that was due on 1 October (advisory A-33-2026). A lower limit means ships transiting the new locks can load less.
What Anxin does: We check the canal advisory in force when we quote for St. Augustine and ask carriers to confirm that the booked vessel's routing and any canal surcharge will not change before sailing.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at St. Augustine 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 St. Augustine, and chase any missing invoice or HTS detail while the ship is still at sea.
- Import country
CPSC certificate data now filed at entry
Since 8 July 2026, importers of consumer products that are subject to a CPSC certification requirement must electronically file the certificate data at entry; goods entered from a Foreign Trade Zone follow on 8 January 2027. Whether a battery-powered product is caught depends on the rules that apply to that product, not on the battery alone.
What Anxin does: We ask whether the goods are consumer products that need a CPSC certificate and, if so, who files it, so that the question is settled before the goods arrive.
- Import country
A monitored US emergency number for the truck leg
The IMDG waiver in 49 CFR 171.25(d)(2) spares the emergency telephone number only when cargo stays on the ship or moves between vessels without using a public highway. Once the container is trucked out of St. Augustine, the shipping paper needs a numeric emergency response number that is monitored at all times and answered by someone who knows the material; an answering service that calls back does not count. Goods shipped as 'Battery powered equipment' are exempt.
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.
Documents & compliance
Checklist for Shenzhen → St. Augustine
Test reports, safety data sheets and import certificates come from the shipper, factory and importer, not from Anxin; our part is to review them before booking.
Before loading in Shenzhen
- Confirmation from the carrier of the DG cut-off at Yantian or Shekou, rechecked in typhoon weeks
- 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)
For the carrier and the voyage
- Canal routing and any canal-related surcharge confirmed for the booked vessel
- 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
- CPSC certificate data and eFiling arrangement, if the product is subject to certification
- Supply-chain tracing file for cells and lithium inputs, in case of a UFLPA request
- Importer of record and the licensed customs broker who will file the entry
Before you book
Match the details first
We line up UN numbers, model names and package counts across the Shenzhen 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 St. Augustine.
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 |
|---|---|---|---|
| Typhoon closes terminals or delays the vessel after filings are made | Yantian / Shekou, Jun–Oct | Slack in stuffing date; refile quickly on vessel change | Anxin with the declarant |
| Draft cut reduces capacity or adds surcharges | Panama Canal | Advisory checked at quotation; carrier confirmation | Carrier, checked by Anxin |
| Truck stopped without a monitored emergency number | Road leg from the port | Emergency response provider confirmed before sailing | Importer, checked by Anxin |
Questions
Shenzhen → St. Augustine: questions we are asked
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.
It can. In September 2026 the Panama Canal Authority postponed a planned draft cut in the Neopanamax locks because of Gatun Lake levels (advisory A-33-2026). We check the advisory in force when quoting.
Since September 2026 Dongguan Customs and Dongguan MSA share dangerous-goods packaging certificate data and act jointly against false declarations, so the packaging certificate and the MSA filing should match exactly.
