From Shanghai to Wilmington (Delaware), cargo moves through Yangshan or Waigaoqiao under Shanghai MSA's photo-verified packing rules, crosses a corridor through the Panama Canal, and is discharged at the port of Wilmington (Delaware).

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

  • Yangshan / Waigaoqiao export
  • Photo-verified packing certificate
  • Supply-chain tracing file
  • HTS code 8507.60
  • ISF filer

Route profile

What sets Shanghai → Wilmington (Delaware) apart

Origin port

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.

Sea corridor

Asia – Americas via the Panama Canal

A Panama Canal corridor whose Neopanamax draft depends on Gatun Lake levels, followed by the Caribbean during hurricane season.

Where this route gets difficult

Where Shanghai → Wilmington (Delaware) shipments get held up: 5 points

They run from the Shanghai terminal through the voyage to Wilmington (Delaware) and the United States import file.

  1. 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.

  2. Sea corridor

    North Atlantic winter storms off the US East Coast

    The last leg north to Wilmington (Delaware) runs up the US East Coast in the North Atlantic, where NOAA's Ocean Prediction Center has recorded hurricane-force mid-latitude storms in every month from October to April, most often in January.

    What Anxin does: For October–April arrivals we check blocking and bracing on stuffing photos before sealing, and allow slack in the delivery plan.

  3. Import country

    Section 301 at 25% on lithium-ion non-EV batteries from January 2026

    USTR's 2024 review moved lithium-ion batteries of HTSUS 8507.60.0020 (the 'other', non-passenger-EV line) from a 7.5% to a 25% additional duty for entries from 1 January 2026; EV traction batteries under 8507.60.0010 reached 25% in 2024. Other China-specific duties can stack on top and change with little notice, so the landed cost depends on the exact classification and entry date.

    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.

  4. Import country

    Where the lithium came from: UFLPA questions at entry

    Since August 2025 lithium has been a high-priority sector under the Uyghur Forced Labor Prevention Act, and CBP had by then stopped more than 16,700 shipments for UFLPA review. A container for Wilmington (Delaware) can be held while the importer shows where the cells, cathode material and lithium compounds were sourced.

    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.

  5. Import country

    Unentered battery containers go to General Order after 15 days

    A container landed at Wilmington (Delaware) 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 Wilmington (Delaware), and chase any missing invoice or HTS detail while the ship is still at sea.

Documents & compliance

What to have ready: Shanghai to Wilmington (Delaware)

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 Shanghai

  • Per-container evidence file (UN38.3 summary, SDS, photos, short-circuit protection) kept for Shanghai MSA spot checks
  • 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
  • UN 38.3 test summary for every cell and battery type
  • Dangerous goods declaration with UN number (3480 / 3481 / 3090 / 3091), proper shipping name and packing instruction (P903, or P908/P911 for damaged)

For the importer in United States

  • HTSUS classification from the broker (8507.60.0010 vs .0020 decides the Section 301 line)
  • Importer of record and the licensed customs broker who will file the entry
  • ISF filer named; stuffing location and consolidator sent right after packing

Before you book

Send the file once, complete

Most delays on this route start with a document that exists but does not match: a UN number, a model name or a package count that differs between the Shanghai filings, the carrier booking and the United States import file. We check the three against each other before the booking is confirmed.

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.

Questions

Questions about shipping from Shanghai to Wilmington (Delaware)

For lithium-ion batteries classified in HTSUS 8507.60.0020 and entered from 1 January 2026, USTR set the Section 301 additional duty at 25%; EV traction batteries in 8507.60.0010 have been at 25% since 2024. Other duties can apply on top. The importer's customs broker confirms the classification and total duty; we make sure the invoice gives the broker enough detail to do so.

1 June to 30 November, peaking around 10 September, according to the US National Hurricane Center.

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.
