How to Calculate the Most Economical Sea Route Between Asia and Colombia
03 Jul 2025

Imagine this: Your container full of products ships from Shanghai to Cartagena. You paid $4,800 for the "direct route." But in the end you discover there was another option for $3,500 with just 7 extra transit days that nobody offered you. What if you could calculate the most economical route for your shipments to Colombia yourself? Today I'll teach you the exact method, even if you've never calculated a sea freight rate before.


1. Why the Shortest Route Isn't the Most Economical for Colombia

You'll be surprised to learn that routes with stopovers can save you up to 30%. Why?

  • Congestion fees at Buenaventura: Colombia's main Pacific port charges delay surcharges

  • Flower season: In February (Valentine's Day), freight rates to Cartagena increase by 35%

  • FTA advantage: Some routes allow better utilization of trade agreements with lower taxes

Real Case: Shipment from Qingdao → Buenaventura

  • Direct route: 32 days = $5,200

  • Panama stopover: 39 days = $4,100
    Savings of $1,100 per container!


2. The 4 Pillars of Actual Costs for Shipments to Colombia

This is how your invoice breaks down when importing to Colombia:

ConceptWhat Is It?Example in Colombia
Base rateBasic container cost40' HC to Cartagena: $2,300-$2,800
BAFFuel adjustment feeJuly 2024: $850 (average)
THCTerminal handling chargesBuenaventura: $130Cartagena: $145
SurchargesAdditional costsDIAN inspection fee: $90

💡 Crucial Tip: Always demand specification of the Buenaventura Port Surcharge (8-12% extra).


3. Step-by-Step Calculation: Shanghai-Buenaventura Example

Let's simulate a textile shipment (40' Dry, 22 tons - October 2024):

Comparative Quote:

CarrierBase rateBAFOrigin THCDestination THC
MSC$2,300$820$95$130
Maersk$2,600$780$105$125
COSCO$2,100$880$85$140

Colombian Surcharges:

  • Buenaventura congestion: +$210

  • CAF (currency adjustment factor): 4.2% on base rate

  • DIAN expenses: $75

Final Result:

MSC: $2,300 + $820 + $95 + $130 + $210 + $75 + ($2,300×0.042) = $3,879
Maersk: $2,600 + $780 + $105 + $125 + $210 + $75 + ($2,600×0.042) = $4,094
COSCO: $2,100 + $880 + $85 + $140 + $210 + $75 + ($2,100×0.042) = $3,733

¡COSCO is the most economical option!
