What Are BAF and CAF?
Interlink編集部What are BAF and CAF?
BAF and CAF are typical surcharges added on top of ocean freight. BAF stands for Bunker Adjustment Factor, which is a cost adjustment for fuel price fluctuations. CAF stands for Currency Adjustment Factor, which adjusts for foreign exchange rate fluctuations.
In ocean transport, in addition to the ocean freight itself, various surcharges may be added depending on factors such as fuel prices, currency exchange rates, peak seasons, container supply and demand, and port congestion. Among these, BAF and CAF are the basic adjustment items.
BAF and CAF may be included within ocean freight or shown as separate charges depending on the shipping line, NVOCC, freight forwarder, route, contract terms, quotation timing, and shipment timing. Therefore, looking at ocean freight alone does not provide a full picture of the total ocean transport cost.
Scope covered in this article
This article organizes practical points to note regarding the meaning of BAF and CAF, how they appear in FCL and LCL, comparing quotes, verifying invoices, and confirming payments. Since related charges such as THC, PSS, CIC, Ocean Freight, and RT serve different purposes, each cost item needs to be checked separately.

What is BAF?
BAF is a surcharge applied to ocean freight to reflect fluctuations in ship fuel costs. Since vessels consume large amounts of fuel, changes in fuel prices directly affect the operating and procurement costs of shipping lines and NVOCCs.
Therefore, in addition to the basic ocean freight, a separate charge called BAF may be invoiced to cover fuel price fluctuations. On quotations or invoices, it may appear under names such as BAF, Bunker Surcharge, Fuel Surcharge, or Fuel Adjustment Factor.
BAF’s display method and calculation units may change depending on the route, shipping line, contract freight, applicable period, container size, and whether it’s FCL or LCL. When comparing quotations, it is important to confirm whether BAF is included in ocean freight or charged separately.
What is CAF?
CAF is a surcharge that adjusts for foreign currency exchange rate fluctuations. Ocean freight and local charges may be denominated in multiple currencies, such as USD, JPY, or local currencies.
Significant currency fluctuations can affect the costs and invoiced amounts of shipping lines, NVOCCs, and freight forwarders. To adjust for this risk, CAF may be applied.
CAF may be listed under terms such as Currency Adjustment Factor, Currency Surcharge, or Exchange Rate Adjustment. It may be clearly specified as CAF on quotations or included within ocean freight or LCL tariffs, depending on the quotation format.
Difference from Ocean Freight
Ocean Freight is the basic charge for transporting cargo from the loading port to the destination port.
In contrast, BAF and CAF are not part of the base ocean freight itself but are additional charges that adjust for fuel cost and currency fluctuations. In other words, ocean freight represents the core transport cost, while BAF and CAF are adjustment fees added on top.
However, depending on the quotation, BAF and CAF may be included within ocean freight or shown as separate line items. Therefore, even if a quotation just states "Ocean Freight," it should be checked whether this amount includes BAF and CAF or if these will be added later.
Common misunderstandings
| Misunderstanding | Correct understanding | Practical notes |
|---|---|---|
| If Ocean Freight is included, no additional charges apply | Even if shown as included in Ocean Freight, additional charges such as BAF, CAF, THC, CFS Charge, D/O Fee may still apply. | Confirm at the time of quotation what is included in Ocean Freight and what is billed separately. |
| BAF and CAF are always fixed rates | BAF depends on fuel prices and CAF on currency fluctuations; both may vary depending on the applicable period. | Check quotation validity period, effective date, and rates at the time of shipment. |
| Calculation units are the same for FCL and LCL | FCL is often calculated per container, while LCL is often calculated per Revenue Ton (RT), so calculation methods differ. | Confirm 20FT/40FT units for FCL and RT or minimum charges for LCL. |
| If BAF and CAF are low, the total cost is also low | Even if BAF and CAF are low, the total cost may be higher if ocean freight, THC, CFS Charge, D/O Fee, etc. are high. | Compare total amounts rather than individual items. |
| BAF is a precise fuel cost pass-through | BAF is a surcharge reflecting fuel price fluctuations, not the actual fuel cost per cargo. | Focus on applicable units, periods, and quotation conditions rather than the basis of rates. |
| CAF is irrelevant to importers | When freight or local charges are denominated in foreign currencies, CAF may also affect the importer’s invoice. | Check whether charges are prepaid or collect, invoicing currency, and conversion rates. |
| BAF and CAF quoted at quotation time will always apply at shipment | Due to validity periods and rate revisions, BAF and CAF may change at the time of shipment. | Confirm the relationship between planned shipment date and quotation validity period. |
BAF and CAF in FCL
In FCL shipments, BAF and CAF are often shown per container unit. They may be set according to container sizes such as 20FT, 40FT, and 40HQ.
In FCL, the ocean carrier's container freight forms the basis. Therefore, BAF and CAF can fluctuate depending on the carrier’s tariff, contracted rates, market conditions, trade routes, fuel prices, and exchange rate conditions.
When estimating for FCL, it is necessary to check not only Ocean Freight but also BAF, CAF, THC, PSS, CIC, drayage, demurrage, and detention fees. It is especially important to confirm the differences in amounts by container size, applicable trade routes, shipment timing, and validity period.
BAF and CAF in LCL
In LCL shipments, BAF and CAF may be set per RT unit. Since NVOCCs or freight forwarders consolidate multiple shippers’ cargo, the surcharges are prorated according to each shipper's cargo volume.
In LCL quotations, BAF and CAF are sometimes included within the Ocean Freight, while other times they are separately itemized as BAF, CAF, Fuel Surcharge, and Currency Surcharge.
In LCL, minimum charges may be applied even for small cargo volumes. Therefore, it is necessary to check not only the unit rates for BAF and CAF but also the RT calculation method, minimum charges, and their relationship with CFS charges and D/O fees.
Differences in Appearance between FCL and LCL
| Check Item | FCL Presentation | LCL Presentation |
|---|---|---|
| Calculation Unit | Often displayed per container unit such as 20FT, 40FT, 40HQ | Often displayed per RT, CBM, or weight unit |
| Relationship with Freight | May be shown separately from Ocean Freight | May appear included in the consolidated freight charge that includes Ocean Freight |
| Basis for Rate | Tends to be linked to carrier tariff, contracted freight, market conditions, and trade routes | May be included in the NVOCC or consolidation operator's LCL tariff |
| Minimum Charge | Calculated per container rather than a minimum charge | Minimum RT and minimum charge may be set |
| Quotation Comparison | Total amount comparison by container size is important | Checking total amount after RT calculation and minimum charges is important |
| Invoice Matching | Match number of containers, size, trade route, and applicable period | Match RT, CBM, weight, minimum charges, and consolidation tariff |
Reasons for BAF Fluctuation
BAF may be revised in response to changes in fuel prices.
If the price of marine fuel increases, BAF may increase. Conversely, if fuel prices decrease, BAF may also decrease. However, the actual billed amount varies depending on the carrier, NVOCC, trade route, contract terms, and applicable period.
In actual logistics practice, the BAF at the time of the quotation may not be the same as the BAF at the actual shipment date. For long-term quotations or future shipment dates, it is necessary to check the possibility of rate revisions.
Reasons for CAF Fluctuation
CAF may be revised according to fluctuations in exchange rates.
Ocean freight is often quoted in US dollars, but billing within Japan may be in Japanese yen. Additionally, local charges or costs at the overseas end may be incurred in different currencies.
To adjust for such currency fluctuations, CAF may be added. When confirming CAF, it is important to verify which currency’s costs are affected and what exchange rate conditions apply at which point in time.
When BAF and CAF are Included
In quotations, BAF and CAF may be included within the Ocean Freight.
In these cases, even if only "Ocean Freight" is shown on the quote, fuel adjustment charges and currency adjustment charges may be included inside. When comparing quotations, it is necessary to confirm whether BAF and CAF are included or added separately.
While inclusion may make things appear simpler, it can make it harder to identify which surcharges are included. Especially when comparing multiple companies’ quotations, it is best to align the basis of comparison whether the charges are included or shown separately.
When BAF and CAF are Shown Separately
When BAF and CAF are itemized separately, they are added on top of Ocean Freight as surcharges.
For example, in FCL, it may be displayed as "Ocean Freight + BAF + CAF + THC." In LCL, it may appear as "Ocean Freight / RT + BAF / RT + CFS Charge / RT."
In the case of separate presentation, it is important to check the unit price, applicable unit, minimum charges, and effective start date. Even if the Ocean Freight quoted appears low, the total cost could be higher once BAF, CAF, and other surcharges are added.
Relationship with RT
In LCL cargo, BAF and CAF may be calculated per RT unit.
RT is a charging unit based on either weight or volume, whichever is larger. In LCL, not only Ocean Freight but also BAF, CAF, and CFS charges may be shown per RT unit.
Therefore, when estimating LCL shipments, it is necessary to confirm not only the unit rates for BAF and CAF but also the definition of RT and minimum charges. Cargo that seems small by CBM may have significant weight, resulting in a larger RT and increased total BAF and CAF.
Watch for Applicable Periods
BAF and CAF may change depending on the applicable period.
The BAF and CAF at the time of the quotation may differ from those at the actual shipment timing. Particularly during periods of large fluctuations in fuel prices or exchange rates, it is important to check the validity period and application conditions of the quote.
For shipments planned far in advance, since surcharges may be revised, it is critical to confirm the quote’s validity period. Confirming which date's rates apply—shipment date, booking date, B/L date, invoice date—also facilitates invoice matching.
Notes on Prepaid and Collect
BAF and CAF may be handled as either Prepaid or Collect charges.
Even if Ocean Freight is prepaid, other local charges or surcharges might arise at the destination. Under collect terms, freight and adjustment charges including BAF and CAF may be billed at the destination.
Cost responsibility should be confirmed based on Incoterms, sales contracts, B/L terms, and the quotation terms with the freight forwarder. It is important not to judge the final cost burden on the seller or buyer solely based on whether charges are Prepaid or Collect.
Differences from PSS and CIC
Like BAF and CAF, PSS and CIC are also surcharges in maritime transport.
BAF adjusts for fuel cost fluctuations, CAF adjusts for exchange rate changes. Meanwhile, PSS is a surcharge related to peak seasons, and CIC may be treated as a surcharge related to container supply-demand balance or imbalances.
Although these surcharges have similar names, their reasons for occurrence differ. In quotations, it is necessary to check what each item specifically adjusts for.
| Item | Main Meaning | Points to Confirm |
|---|---|---|
| BAF | Cost adjustment for fuel price fluctuations | Confirm applicable period, trade route, container unit or RT unit. |
| CAF | Cost adjustment for exchange rate fluctuations | Check billing currency, conversion rate, and whether Prepaid or Collect. |
| PSS | Surcharge added during peak shipping seasons | Confirm application period, route, and shipment timing. |
| CIC | Surcharge related to container supply-demand and imbalances | Verify origin and destination, container size, and trade route. |
| THC | Handling charges at terminal | Check origin/destination side, FCL or LCL, and Prepaid or Collect status. |
| CFS Charge | Handling charges for LCL cargo at CFS | Confirm RT, minimum charge, and scope of inbound/outbound costs. |
Step-by-Step Flow from Quotation to Payment Confirmation
| Stage | What to Confirm | Practical Issues | Actions if Issues Arise |
|---|---|---|---|
| When Obtaining Quotation | Display of Ocean Freight, BAF, CAF, THC, CFS Charge, D/O Fee | Total cost comparison differs depending on whether charges are included or itemized separately. | Confirm which costs are included and which are extra by item. |
| When Comparing Quotations | FCL by container unit, LCL by RT unit, minimum charges, applied currency | Comparing unit prices alone may reverse the total cost order. | Calculate and compare total cost based on the same assumptions. |
| At Booking | Planned shipment date, route, container size, cargo volume, applied rate | BAF and CAF may change between the quotation and booking stages. | Check quotation validity period and whether rates have been revised. |
| At B/L and Shipment Confirmation | Prepaid/Collect, freight display, applicable date, billing party | The billed party or cost bearer may differ between B/L display and actual billing. | Cross-check sales contract terms, quotation terms, and B/L conditions. |
| Upon Invoice Receipt | BAF/CAF unit price, quantity, RT, number of containers, minimum charge | Invoice amounts may vary due to differences in quantity calculation or RT calculation. | Reconcile quotation, booking, cargo details, and invoice. |
| When Confirming Payment | Billing currency, exchange rate conversion, tax category, payee, internal cost center | When costs are charged in foreign currencies or include CAF, exchange rates should be checked. | Confirm conversion conditions, payment currency, and internal accounting amounts. |
| Post-Verification | Difference between quotation and actuals, surcharge fluctuations, reflection in next quotation | Without understanding reasons for differences, accuracy in future quotations may decline. | Organize rate revisions, cargo volume discrepancies, and reasons for additional costs. |
Items to Check When Comparing Quotations
When reviewing BAF and CAF, it is necessary to organize the cost items affecting the total amount, not just the Ocean Freight.
| Check Item | What to Check | Notes |
|---|---|---|
| Included or Separate | Whether BAF and CAF are included in Ocean Freight or added separately | Compare included and separately listed quotations on the same basis. |
| Calculation Unit | By container for FCL, by RT for LCL | Confirm if minimum charges apply for LCL. |
| Application Timing | Rate at the time of quotation, booking, or shipment | Rates may change at shipment time. |
| Quotation Validity Period | Until when the quotation is valid | Reconfirmation may be needed for bookings after the validity period. |
| Prepaid or Collect | Which party is billed | Cross-check with Incoterms and sales contract to confirm cost bearer. |
| Other Surcharges | PSS, CIC, THC, CFS Charge, D/O Fee, etc. | Total cost comparison cannot be done by Ocean Freight alone. |
| Billing Currency | USD, JPY, local currency, etc. | Check CAF and exchange rate conversion. |
Common Practical Issues
| Case | Issue | Documents to Check | Practical Response |
|---|---|---|---|
| Selected a quote based only on the cheapest Ocean Freight | BAF, CAF, and THC were charged separately, resulting in a higher total cost | Quotation, surcharge details, total cost calculation sheet | Compare not only Ocean Freight but also the total cost including all charges. |
| Compared quotations with BAF/CAF included and quoted separately as-is | Different presentation methods meant assumptions for comparison were not aligned | Quotation, breakdown details, freight forwarder response | Confirm whether charges are included or billed separately, and align the expense scope before comparing. |
| BAF charged per RT in LCL, leading to higher-than-expected cost | RT increased depending on cargo volume and weight, increasing the total BAF/CAF | Cargo details, CBM, weight, RT calculation, quotation | Confirm the RT calculation method and minimum charge in advance. |
| BAF was revised after quotation was obtained | Rate changed between quotation and shipment, causing increased billing | Quotation, quotation validity period, booking date, shipment date, invoice | Check quotation validity and the date used to apply the rates. |
| Did not confirm the conversion basis for CAF | Billing differed from expected due to currency conversion for freight in foreign currency or local currency charges | Invoice, exchange rate conversion details, quotation, payment terms | Confirm billing currency, conversion rate, and conversion date. |
| BAF/CAF expected to be prepaid was billed as Collect | B/L display, quotation terms, and payer recognition did not match | B/L, quotation, invoice, sales contract | Match Prepaid/Collect status with the party responsible for the cost per sales terms. |
| Overlooked the difference in BAF between 20FT and 40FT FCL containers | Surcharges differ by container size, causing variation in total quote amount | Quotation, container size, booking, invoice | Confirm unit prices for 20FT, 40FT, and 40HQ containers separately. |
| Quantity calculation for BAF/CAF in invoice differed from quote | Differences in understanding RT, container count, minimum charge, and applied unit | Quotation, invoice, packing list, booking, cargo details | Cross-check quantities, RT, minimum charges, and applied units to identify reasons for discrepancy. |
Concrete Examples
Case of selecting a quote based only on cheap Ocean Freight
Consider a case where an importer obtained LCL quotations from multiple freight forwarders and selected the cheapest based only on Ocean Freight unit price. In the chosen quote, Ocean Freight was shown as lower, but BAF, CAF, CFS Charge, and D/O Fee were billed separately.
In contrast, other quotations included BAF and CAF within Ocean Freight, making the Ocean Freight appear higher on the surface. However, when calculating the total cost, the initially chosen quotation was actually more expensive.
In this case, it was necessary to compare all charges, including BAF and CAF, under the same conditions, not just Ocean Freight. For quotation comparison, it is important to confirm the actual total amount payable rather than just the item names.
Case where BAF/CAF was higher than expected due to RT calculation in LCL
Consider a case where for LCL transport of small cargo, the cargo owner estimated costs based only on CBM. The cargo volume appeared small, but the weight was heavy, so the RT calculation was based on weight.
As a result, BAF, CAF, and CFS Charge were calculated based on a higher RT than expected, and the invoice amount exceeded the estimate. The shipper had confirmed BAF/CAF unit prices but did not sufficiently check the RT calculation method.
In this case, CBM, weight, RT, and minimum charges should have been checked at the time of LCL quotation. For LCL, it is not only the unit price of BAF/CAF but also the charging unit that matters.
Case where BAF was revised after quotation, changing the invoiced amount
Consider an exporter who obtained a quotation for FCL cargo a few weeks before the shipment date. At the quotation time, BAF was shown at a fixed rate, but subsequently, due to fluctuations in fuel prices, the shipping line revised the surcharges.
Since the actual booking and shipment occurred after the quotation validity expired, the invoice reflected the new BAF, making sea transport costs higher than initially quoted. The exporter expected the quotation amount to be applied as-is, requiring internal and customer billing explanations for the difference.
In this case, it was necessary to check the quotation expiry, BAF application timing, estimated shipment date, and possibility of rate revisions in advance. BAF and CAF should be handled as variable charges that fluctuate depending on the application period and are not fixed costs.
Case where CAF was charged on the destination side under Collect terms
Consider a case with import cargo under Collect treatment for ocean freight. The importer assumed that major charges had been prepaid by the seller, but CAF was billed alongside Ocean Freight on the destination side.
Upon review, the freight terms on the B/L, contract pricing, and freight forwarder's quotation terms were not fully aligned, causing misunderstandings among parties about which charges were prepaid and which were Collect.
In this case, it was necessary to confirm at the quotation stage whether BAF and CAF were prepaid or collect, and who ultimately bears the cost. It is important to verify not only the charge items but also the payment location and responsible party.
Practical Confirmation Checklist
| Check point | Party to check with | Items to confirm | Actions if problems arise |
|---|---|---|---|
| When obtaining a quotation | Freight forwarder, NVOCC, carrier | Whether BAF/CAF is included in Ocean Freight or charged separately | Request the quotation to clearly specify included and separate charges. |
| When comparing quotations | Internal personnel, freight forwarder | FCL is per container, LCL is per RT, presence of minimum charges | Calculate the total amount under the same cargo conditions; do not compare by unit price alone. |
| At booking | Freight forwarder, carrier | Quotation validity period, planned shipment date, applicable surcharge rates, any rate revisions | If beyond quotation validity, obtain re-quotation or confirm rates again. |
| When checking B/L | Freight forwarder, NVOCC, carrier | Freight Prepaid / Collect, bill-to party, who bears the charges | Reconcile trade terms with B/L statement and billing conditions. |
| When receiving invoice | Freight forwarder, accounting department | BAF/CAF unit price, quantity, RT, number of containers, minimum charges, currency | Match invoice with quotation, booking, and cargo details. |
| At payment confirmation | Accounting department, freight forwarder | Exchange rate conversion, payment currency, tax classification, internal cost center | Confirm conversion conditions for CAF and foreign currency charges. |
| At next quotation request | Sales, logistics personnel, freight forwarder | Difference from previous quotation, surcharge fluctuation, improvements in quotation conditions | Record reasons for differences and reflect them in the next quotation request conditions. |
Practical Points to Note
BAF and CAF are representative surcharges added to ocean freight. BAF relates to fuel costs, and CAF relates to currency exchange fluctuations.
For FCL, these may be shown per container, while for LCL, they may be displayed per RT or as additional items under consolidated tariffs. Even when using the same names BAF and CAF, actual billing amounts can vary significantly depending on calculation units, applicable periods, whether included or separate, and presence of minimum charges.
When comparing ocean freight, it is important to check not only whether BAF and CAF are included or separate from Ocean Freight, but also the applicable periods, calculation units, minimum charges, and total amounts including other local charges.
Summary
BAF and CAF are typical ocean freight surcharges added separately from Ocean Freight to adjust for fuel cost and currency fluctuation. BAF is related to fuel costs, while CAF relates to currency exchange costs.
They are often presented per container for FCL and per RT for LCL, and may either be included in Ocean Freight or charged separately. When comparing quotations, it is necessary to verify not only unit prices and item names but also total amounts, applicable periods, minimum charges, prepaid or collect terms, and billing currencies.
BAF and CAF are not fixed costs; they may change depending on fuel prices, currency rates, carrier and NVOCC tariff revisions, and quotation validity periods. Confirming costs under the same conditions from quotation to invoice reconciliation and payment confirmation is fundamental in ocean freight and local charge operations.
