Sea freight is the volume backbone on China→USA when unit cost matters more than speed. Use air when must-arrive is tight; use DDP when you want a scoped door offer instead of buying ocean + clearance separately—see the USA hub and sibling spokes.

Transit + Cost Position
🚢 Sea
Typical illustration band: about ~14–22 days port-to-port to the US West Coast and ~30–45 days to the East Coast by string and routing; door-to-door adds terminal, CBP, and inland.
✈️ Air
Typical band: roughly a few days airport-to-airport once uplifted; far higher cost on chargeable weight than ocean per CBM.
📦 DDP
Same sea or air transit underneath; changes who files entry with CBP and pays duty/fees, not vessel speed.
In 2026 Trans-Pacific ocean moves with capacity, season, and equipment. Treat coast day bands as illustration only—confirm the booked schedule, not a brochure promise. FCL usually wins above sustained LCL volumes; LCL covers under-container sizes, but handling and dwell can erase savings. West Coast (Los Angeles/Long Beach, Oakland) vs East Coast (NY/NJ, Savannah) or Gulf (Houston) is inland map plus free time plus ISF—not a logo contest. Free time and demurrage risk at US terminals is a sea-spoke cost lever: model it before you celebrate a cheap ocean line. Landed cost includes origin charges, ocean, destination local, possible demurrage/detention, and rail/truck to ZIP. When inland is rail to the Midwest, model railyard dwell and warehouse appointments with the same rigor as ocean ETA.

Origin Hubs + Destination Handoff
🇨🇳 Where cargo leaves China
- Shanghai / Ningbo for the Yangtze
- Yantian / Shenzhen / Guangzhou for the Pearl River Delta
- Qingdao / Tianjin for the north—drayage to port affects vessel cutoff
🇺🇸 Where it lands in the USA
- Los Angeles / Long Beach / Oakland: West Coast gravity for many Asia programmes
- NY/NJ and Savannah: East Coast by network and final inland
- Houston and other Gulf when the distribution map requires it
Handoff is terminal plus CBP entry plus inland—not the ship ETA. A box “arrived LA” is not available in Chicago or Dallas until rail/truck and release allow it. Losing free time on LA/LB docks remains one of the most expensive ways to destroy a competitive ocean rate. Coast choice without the final warehouse ZIP is weak design.
Only-here on USA sea: (1) West vs East Coast changes inland rail/truck design—not just ocean days. (2) ISF (10+2) is a US ocean-specific control—core data is generally due no later than 24 hours before foreign lading; late or inaccurate filings can draw liquidated damages and holds that air/DDP pages do not own. (3) Free time and demurrage at US terminals is a sea cost lever—label day bands as typical and push a dated quote. Duty by HTS does not vanish because you chose ocean. Document shipper/consignee exactly as they will appear on B/L and ISF. Confirm handoff against Port of Los Angeles and Port Authority of NY & NJ when you scope destination clearance and gateway delivery.
Origin execution
China CY cutoff and ISF data before US loading
On China→USA ocean, SIS (or your forwarder) consolidates at Shanghai, Ningbo, Yantian/Shenzhen, or Qingdao before the CY cutoff for the booked Trans-Pacific string. Vessel space, equipment, and inland drayage to the load port decide whether you catch the sailing you planned. Core ISF data must be ready before foreign lading—late shipper/consignee or HTS inputs are an origin execution failure, not a West Coast terminal problem. Confirm the POL and B/L parties in writing with the same names that will appear on ISF.
Local reality
West vs East Coast handoff, CBP release, and inland ZIP
After berthing at LA/Long Beach, Oakland, NY/NJ, Savannah, or Houston, cargo still needs CBP entry, terminal free time discipline, and rail or truck to the final ZIP. A box “arrived LA” is not inventory in Chicago until inland release allows it. ISF liquidated-damages risk sits on ocean into the US; duty by HTS (and any additional China-origin tariff layers) does not vanish because you chose sea. Model free time and demurrage before you celebrate a cheap ocean line.
Cost example
Example only — FCL Shenzhen to Los Angeles vs East Coast inland
Example only / illustration — not a live all-in offer. Typical planning shape for a China FCL into LA/LB: ocean + origin extras, then destination THC/handling, then duty/fees by HTS, then inland to ZIP. East Coast door totals often run higher on the same cargo because longer ocean plus different rail/truck. Free-time burn at the terminal can erase a competitive ocean line in days. Request a dated quote with coast, ZIP, FCL/LCL, and HTS assumptions—never treat a brochure band as a promise.
When to Use (and When Not)
Sea to the USA usually fits when:
- ✓ Replenishment volume and the calendar tolerate ocean plus inland
- ✓ FCL with coast and inland aligned to the real warehouse or FBA/DC
- ✓ You want the lowest freight per CBM versus air
It is usually the wrong call when:
- ✕ Must-arrive only air can cover
- ✕ You compare ocean line alone without free time, ISF, or inland
- ✕ Final ZIP contradicts the coast you chose by habit
2026 reality: Trans-Pacific service density is high, but commercial outcome is decided by entry readiness and inland design. Use DDP only with explicit duty/fees scope—not as a label to hide weak HTS. If part of the volume is LCL, re-check the threshold against a 20′ FCL with same-week numbers. As of 29 Aug 2025, CBP: goods valued at or below $800 are no longer eligible for duty-free de minimis treatment and are subject to applicable duties, taxes, and fees. Do not plan on pre-suspension Section 321 duty-free language; indefinite non-postal suspension regs apply from 24 Jun 2026—confirm current CBP guidance.
