Port areas named for Shenzhen

Shenzhen is the main export gateway for the electronics and battery manufacturing belt on the east bank of the Pearl River Delta. Container exports leave mainly through the Yantian port area in the east and the Shekou and Mawan port areas in the west.
Some cargo reaches the Shenzhen port areas by Pearl River Delta barge rather than by truck; that is confirmed per shipment.
Ocean routing
FCL, LCL and any transshipment for Grays Harbor are confirmed per booking with a carrier that accepts the declared UN numbers; this page does not promise a direct sailing or a transit time.

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.
Routing and sailing schedules vary by carrier, cargo type and booking date. Confirm the current schedule with our team.

Destination & import
Destination scope · United States
Port, customs release and final address are separate steps
Working classification: port / terminal area.

The importer of record, normally through a licensed broker, clears the goods with U.S. Customs and Border Protection (CBP). Anxin supplies shipping and battery documents; it does not act as importer.
After discharge, cargo usually moves by drayage to a warehouse or rail ramp, then by truck (FTL/LTL) or rail intermodal. Domestic legs for battery cargo follow U.S. hazardous-materials rules where they apply.
Delivery beyond Grays Harbor is part of the quote only when a final address is named.

Questions
Usually Yantian, Shekou or Mawan, depending on the carrier and booking. The three options are door pickup (factory or warehouse pickup across Shenzhen, Dongguan and Huizhou), delivery to a warehouse or CFS that handles battery cargo, or delivery to the terminal gate; the quote states which one applies.
Only when the booking and bill of lading name Grays Harbor (46.98°N, 123.95°W). A city or country name in an enquiry is not proof of discharge; after the port, customs release and delivery to an address are separate steps.
Start with the cargo description, battery configuration, condition statement, UN 38.3 test summary and SDS. The checklist on this page lists the rest.
