7 Common Import–Export Mistakes That Quietly Increase Costs — And How Businesses Can Avoid Them

In international trade, unexpected expenses don’t always come from market volatility or rising freight rates. Very often, small operational mistakes lead to delays, extra charges, or disruptions in the supply chain. Below are seven common errors that businesses frequently encounter — along with practical ways to avoid unnecessary costs.

1. Inaccurate documentation or mismatched information.

Even a small inconsistency between the Invoice, Packing List, and Bill of Lading can trigger customs inspections or red-channel checks. For agrochemicals or specialty goods, incorrect HS codes may also result in wrong tax rates or extended clearance time.

Solution:

• Use a document checklist before submission.

• Cross-check product name, HS code, quantity, weight, and origin across all documents.

• For chemicals, verify CAS No. and technical descriptions to ensure proper classification.

2. Choosing the wrong Incoterms — leading to unexpected costs.

Many businesses still use FOB/CIF out of habit, but each Incoterm carries different responsibilities and charges such as local fees, D/O fees, CIC, handling charges…

For CIF imports, buyers may face higher costs if the seller selects a designated forwarder with limited transparency.

Solution:

• Clarify cost responsibilities early in the contract.

• For high-value or time-sensitive cargo: consider DAP/DPU or FCA for better control.

• For low-value or routine shipments: FOB/CIF may still be practical.

3. Booking vessels too late — higher risk of rollover or rescheduling.

During peak seasons (late Q2, late Q4) and month-end periods, vessel space fills up quickly. Late booking often leads to:

• Rollover to a later vessel.

• Earlier closing time.

• Sudden sailing cancellations.

This can cause production delays, missed crop seasons, or additional storage and handling charges.

Solution:

• Book 5–10 days in advance for China routes; 10–14 days for India routes.

• Add buffer time for shipments supporting production schedules.

• Monitor actual vessel schedules — don’t rely solely on initial ETD.

4. Not preparing for local charges and seasonal surcharges.

Local charges in Vietnam can account for 10–20% of logistics costs if not planned properly: THC, CIC, Cleaning, EBS, AMS, ISF, Seal fee…

Solution:

• Always request an “all-in” quotation with clear fee breakdown.

• Compare charges among forwarders to avoid hidden costs.

• Monitor seasonal surcharges during storm seasons or peak periods, especially on China and India routes.

5. Incorrect Dangerous Goods (DG) declaration.

For pesticides, fertilizers, and chemical goods, mismatching UN Number, Class, or Packing Group can lead to:

• Vessel rejection.

• Repacking or rebooking costs.

• Stricter documentation checks or delays.

Solution:

• Review MSDS Section 14 carefully.

• Check the correct IMDG Code version.

• Submit DG details to the carrier early — not last minute.

6. Miscalculating clearance timing around weekends and holidays.

If cargo arrives on a weekend, holiday, or after working hours, businesses may incur extra storage or demurrage even without any mistake on their part.

Solution:

• Choose ETA between Monday–Thursday for smoother clearance.

• For goods requiring quarantine or chemical inspections: avoid Friday arrivals.

7. Missing documents during customs inspections or red-channel checks.

Agrochemicals and agricultural inputs often require CO, CQ, MSDS, catalogues, test reports… Missing just one can extend clearance time and disrupt supply for farms or factories.

Solution:

• Prepare a full document package during contract negotiation.

• Keep soft copies for quick submission if needed.

• For first-time imports: consult customs or import specialists beforehand.

Final Note.

Import–export operations don’t have to be complicated. With careful preparation, early booking, and precise documentation, businesses can significantly reduce avoidable costs — and keep their supply chain running smoothly, especially for agricultural, seasonal, and production-driven goods.
