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.

From Shanghai to Sacramento, cargo moves through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules, crosses the open North Pacific, where weather is the main risk, and is discharged at the port of Sacramento.
US entry is decided as much by paperwork filed in China as by anything at the port. Below are 6 route-specific points to plan for, what we do about each, and the documents to have ready before booking.
What we need to start
- Yangshan / Waigaoqiao export
- Photo-verified packing certificate
- Supply-chain tracing file
- HTS code 8507.60
- ISF filer
Route profile
The Shanghai → Sacramento route in brief
Transpacific (North Pacific)
A great-circle route across the North Pacific, exposed to hurricane-force winter storms from October to April.
Where this route gets difficult
Where Shanghai → Sacramento shipments get held up: 6 points
In the order the cargo meets them: at the loading port, at sea, at Sacramento and at customs in United States.
- Origin port
Not every Shanghai warehouse can stuff lithium DG
Shanghai MSA's 2024 draft reporting guide says warehouses that stuff lithium battery dangerous goods must provide fire-department proof of their fire hazard classification and fire-resistance rating. The site's information must also be up to date on the Shanghai single window, which took over MSA account and site records in 2026.
What Anxin does: We only propose stuffing sites that can show the fire-safety documents and are on Shanghai MSA's system; if you use your own warehouse, we check this before booking.
- Origin port
Shanghai checks during and after the voyage filing, not just before
Shanghai MSA's Notice No. 4 of 2024 accepts either an inspector-signed packing certificate or a packing declaration from the stuffing company, but places the burden on the shipper: the batteries must meet the UN tests and be protected against damage, short circuit and accidental activation, and MSA runs spot checks during and after the process, with proof to be produced on request.
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.
- Sea corridor
An open-ocean crossing where weather is the main risk
From Shanghai the drawn corridor to Sacramento runs across the North Pacific without a canal or Red Sea passage, so weather replaces chokepoints as the risk. The ONE Apus, bound from Yantian to Long Beach in November 2020, had a stack collapse in a storm about 1,600 nautical miles north-west of Hawaii; her owners said more than 1,900 containers could be lost or damaged, up to 40 of them hazmat.
What Anxin does: For winter sailings especially, we review blocking and bracing on stuffing photos against the CINS points before sealing, and make sure the DG declaration is complete, so a damaged box can be identified and handled correctly.
- 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 Sacramento booking, we check the carton photos for the US marking or CAO label before stuffing, not after discharge.
- Import country
Unentered battery containers go to General Order after 15 days
A container landed at Sacramento 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 Sacramento, and chase any missing invoice or HTS detail while the ship is still at sea.
- Import country
California's battery-embedded product rules since January 2026
Under California SB 1215, consumers have paid a recycling fee on covered battery-embedded products since 1 January 2026, and those products must be labelled with the maker's name or brand and the battery chemistry, or give that information on the maker's website. Manufacturers must also list covered and exempt products in an annual notice to retailers and CalRecycle.
What Anxin does: If the goods landing at Sacramento are devices with built-in batteries for sale in California, we ask the brand owner to confirm the chemistry labelling and the CalRecycle notice before shipping.
Documents & compliance
Checklist for Shanghai → Sacramento
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.

- 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

- 24-hour emergency response number (and provider reference) for the US road leg
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 Shanghai 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
What could go wrong from Shanghai to Sacramento, and who acts
| Risk | Where | Mitigation | Who acts |
|---|---|---|---|
| Post-event spot check finds missing proof | Shanghai MSA | Evidence file kept per container | Shipper with Anxin |
| Stack collapse or cargo shift in a North Pacific storm | Mid-Pacific | Blocking and bracing checked before sealing; complete DG data for incident response | Packing site / carrier, checked by Anxin |
| 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
Questions about shipping from Shanghai to Sacramento
Yes, if the container moves on a public highway. The IMDG waiver in 49 CFR 171.25(d)(2) only covers cargo that stays on the ship or moves between vessels; otherwise 49 CFR 172.604 requires a monitored number answered by someone with the emergency information. Goods shipped as 'Battery powered equipment' are exempt.
Weather is the main risk on this crossing: NOAA recorded hurricane-force North Pacific storms from October to April, most often in December. We tighten the packing checks for those sailings.
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.
