1. The discrepancy taxonomy
Document discrepancies that block customs clearance fall into four types.
Data inconsistency: the same fact stated differently across documents.
Content deficiency: a required element missing.
Form problem: the document in the wrong format or lacking a required certification.
Timing problem: a document that is right but late or expired.
2. Data inconsistency
The most common type.
Consignee differences
The invoice names one consignee and the bill of lading names another.
Quantity differences
The packing list and the certificate of origin differ.
Value differences
The invoice and the certificate of origin differ.
Description differences
The goods are described in terms that do not correspond across documents.
The fix: one master data sheet, used to prepare every document.
3. Content deficiency
A required element is missing.
Destination-specific fields the exporter did not know were required.
The origin criterion on the certificate of origin left blank.
The HS code at a national level not matching the destination’s schedule.
The fix: a document checklist per destination, reviewed before the shipment.
4. Form problems
The document is in the wrong form.
The certificate of origin is not the form the destination requires.
The invoice is not legalized where legalization is required.
The bill of lading is a sea waybill where the credit requires originals.
The fix: confirm the required form for each document, per destination.
5. Timing problems
The document is correct and unusable.
The certificate of origin is issued after the shipment date where retroactive issuance is not permitted.
The legalized document arrives after the customs entry is filed.
The free sale certificate has expired.
The fix: work backwards from the shipment date.
6. The compounding effect
A discrepancy rarely comes alone.
A consignee difference on the bill of lading produces a customs query, which triggers examination, which reveals a value difference on the invoice, which triggers a valuation review.
The initial discrepancy is a delay. The compounding is an examination.
7. The correction routes
Before the goods arrive
Correct the documents at origin. Reissue the certificate, amend the bill of lading, re-legalize the invoice.
The fastest route and the cheapest.
After the goods arrive
Depends on the destination.
Some customs authorities allow amendment on application.
Some require the consignment to be held pending resolution.
Some allow the importer to provide a guarantee and clear, with the discrepancy resolved later.
Where the goods cannot clear
Re-export, abandonment or destruction.
The outcome exporters want to avoid.
8. The prevention checklist
Before the shipment:
One master data sheet, used across all documents.
A destination-specific checklist.
Form requirements confirmed.
Legalization requirements confirmed and sequenced.
Dates worked backwards from the shipment.
A second person checking the document set against the master data.
9. Why the second check matters
The exporter who prepared the documents knows what they meant to write.
A second reader sees what is written.
The discrepancy rate between the two is substantial, and the check takes ten minutes.
10. Closing view
Discrepancies are almost always a process problem rather than a knowledge problem.
The exporter knew the requirement. The documents were prepared in sequence, by different people, from different sources.
The master data sheet and the second check address exactly that.
