Ocean Freight Surcharges Explained: What Every Line Item on Your Quote Actually Means
Shipping basics · Updated
When you receive an ocean freight quote for a China-to-US shipment, the base rate is just the starting point. Carriers and freight forwarders layer on surcharges that together add 30% to 80% to the total cost. Most small importers accept these without knowing what they are.
This guide explains the most common surcharges on a China-to-US ocean freight quote, what each one is supposed to cover, and where there is room to push back.
Key takeaways
- --Ocean freight surcharges add 30% to 80% on top of the base rate. Always compare all-in quotes, not base rates.
- --BAF (fuel surcharge) is the most variable component -- it moves with global bunker fuel prices and adjusts quarterly or monthly.
- --THC, AMS fees, and customs user fees are set by terminal operators and government agencies -- not negotiable.
- --GRI and PSS are carrier-wide increases affecting all shippers simultaneously.
- --Always ask your freight forwarder for a total cost including all surcharges to the destination port before booking.
Fuel surcharges: BAF and EBS
Bunker Adjustment Factor (BAF): the most common fuel surcharge. Carriers add BAF to recover the cost of bunker fuel. BAF rates fluctuate with global fuel prices and are adjusted quarterly or monthly. It is quoted per TEU or per container.
Emergency Bunker Surcharge (EBS): an additional fuel surcharge imposed on top of BAF during sharp fuel price increases. It appears and disappears depending on market conditions.
Low Sulphur Surcharge (LSS): added after the IMO 2020 rule requiring ships to use lower-sulphur fuel. The higher cost of compliant fuel passes through as LSS. Many carriers have since folded this into BAF.
GRI and PSS: rate increase surcharges
General Rate Increase (GRI): carriers announce GRIs when demand increases or capacity tightens. A GRI is a blanket increase to the base rate, quoted per container. Carriers typically give 30 days' notice. GRIs are common in Q3 (pre-holiday buildup) and after Chinese New Year.
Peak Season Surcharge (PSS): applied during high-demand periods, typically July through October on trans-Pacific lanes as US importers build holiday inventory. PSS stacks on top of GRI and typically ranges from $200 to $800 per container.
Both GRI and PSS are carrier-imposed and apply across the market simultaneously. They are not negotiable for individual small shippers.
Terminal handling charges: THC
Terminal Handling Charge (THC): charged at both origin and destination for moving the container within the terminal. THC is set by the terminal operator, not the carrier, and is non-negotiable.
Origin THC (OTHC): charged at the Chinese port terminal. Typically $80 to $150 per container.
Destination THC (DTHC): charged at the US port terminal. Typically $150 to $350 per container.
Port Congestion Surcharge (PCS): applied when a specific port experiences congestion causing vessel delays. Common during LA/LB congestion events. Temporary and terminal-specific.
Equipment and documentation surcharges
Container Imbalance Surcharge (CIS): carriers move more containers westbound (China to US) than eastbound. To reposition empty containers back to Asia, they charge CIS. Typically $100 to $300 per container.
Bill of Lading (B/L) Fee: charged for issuing the bill of lading. Typically $50 to $100 per shipment.
Chassis Split Fee: if the chassis for your container must come from a different location than the container, a split fee applies at some US terminals. Typically $50 to $150.
Overweight Surcharge: if your container exceeds the terminal or carrier weight limit, a surcharge applies.
Regulatory surcharges
Automated Manifest System (AMS) Fee: CBP requires electronic cargo manifest filing before arrival. Carriers charge an AMS fee to cover the filing. Typically $25 to $60 per bill of lading.
US Customs User Fee (Harbor Maintenance Fee and Merchandise Processing Fee): CBP-mandated fees collected at entry. The Merchandise Processing Fee is 0.3464% of the cargo value (minimum $29.66, maximum $575.35 per entry). These are government fees, not carrier revenue.
What is negotiable and what is not
Non-negotiable: THC, AMS fee, customs user fees. These are set by terminal operators or government agencies and are passed through at cost.
Carrier-set but market-wide: GRI, PSS, BAF, EBS. These apply across the market and are not discounted for individual small shipments.
Potentially negotiable: the base ocean freight rate, especially with volume or long-term commitment. Freight forwarders who consolidate volume across clients can sometimes access better all-in rates than a single small shipper obtains directly.
Red flag: a quote with a very low base rate that loads surcharges. Always compare all-in rates rather than base rates when evaluating freight quotes.
FAQ
Why is the total freight cost so much higher than the base rate quoted?
Surcharges -- BAF, PSS, GRI, THC, AMS, and others -- typically add 30% to 80% on top of the base ocean freight rate. Always ask for an all-in quote that includes all surcharges to the destination port.
What is BAF and why does it change?
BAF (Bunker Adjustment Factor) is a fuel surcharge carriers add to recover bunker fuel costs. Bunker fuel prices fluctuate with global oil markets, and carriers adjust BAF quarterly or monthly to track those changes.
What is a GRI and when does it happen?
GRI (General Rate Increase) is a blanket increase to ocean freight rates announced by carriers, typically with 30 days' notice. GRIs happen when demand increases -- typically Q3 pre-holiday season and after Chinese New Year -- or when capacity tightens.
Can I negotiate ocean freight surcharges?
THC, AMS fees, and customs user fees are set by third parties and are not negotiable. BAF, GRI, and PSS are market-wide and not negotiable for individual small shipments. The base ocean freight rate is the component most open to negotiation, especially for shippers with volume or annual contracts.
What is the difference between PSS and GRI?
GRI is a broad rate increase applied when the carrier wants to raise rates generally. PSS is a temporary add-on specifically during high-demand periods -- usually July through October on trans-Pacific lanes. Both can apply simultaneously and both stack on top of the base rate.
