Prevalidation is the electronic review an authorized prevalidator runs on the pedimento file before it reaches the customs authority system. It checks syntax, catalogs, and data congruence: that the heading exists, keys are valid, and required fields are complete. It is not a customs approval or a legal sign-off: it only confirms the file is well-formed. When it errors, the pedimento does not advance to validation, and your operations clock keeps running.

The difference between losing two hours and losing the day is knowing which field is wrong, what its source is, and who fixes it.

Prevalidation is not validation
Confusing them costs: “it already passed prevalidation” does not release the operation or guarantee value or regulations. It means the file has no obvious capture errors.
Prevalidation is not validation
Clearing the prevalidator only means the file is well-formed.
| Prevalidation | Validation | |
|---|---|---|
| Who | Authorized prevalidator | Authority system |
| Checks | Syntax, catalogs, structure | Regulatory congruence |
| Output | Receipt or error list | Signature for payment/clearance |
| Passing means | Well-formed file | Clearance can continue |
How to read the error message
Errors arrive with a code and a short description. The method is always the same: flagged field, data source, fix at origin, log the cause.
How to read the error without guessing
Field, source y fix at origin a log the cause.

Not the symptom
Errors that keep repeating
Document keys that do not match the regime, obsolete HS or NICO, inconsistent RFC, bad COVE reference, quantities that do not reconcile. None are “the system’s fault”.
Errors that repeat most
None are “the system’s fault”: each has an unreconciled source.
01
Catalogs
Missing/obsolete HS or NICO, or wrong regime key.
02
Identity
Importer RFC inconsistent with the registry; bad COVE or e-document reference.
03
Quantities
Units of measure that do not reconcile across lines and origin documents.
Trip file and broker
If you only patch the file and the error was born in the trip file, the same rejection returns. Ask your broker for the template where the data lives. Cluster: rectification, pedimento, DODA.
What OCL runs
OCL Cargo is an autonomous TMS with agents and computer use (operating screens and portals like an analyst). It builds the trip file per shipment, cross-checks evidence, and leaves exceptions to humans. It coexists without a day-one TMS migration. OCL can stamp invoice and Carta Porte. On the Mexico–US corridor, the value is closing the trip file before paying.

Key takeaways5 points
- Prevalidation confirms syntax and catalogs, not legality or classification.
- Every error is fixed against the data source, not against memory.
- Recurring errors live in the catalog or template, not in one-off keying.
- Clearing prevalidation does not prevent a later rectification.
- OCL builds the trip file per operation and reconciles before the yard bills.

Frequently asked questions
No. It guarantees the file is well-formed. Classification, value, and regulations remain the declarant's responsibility.
The fee appears on the pedimento and is absorbed by the importer or exporter. Review it: almost nobody audits it.
Fix the catalog or template where the data lives. A recurring error is a file problem, not a keying problem.
No. Prevalidation: authorized private prevalidator. Validation: authority system that enables payment and clearance.
Autonomous TMS with agents: trip file per shipment, source cross-check, and incongruity alerts. It can stamp invoice and Carta Porte. Humans on exceptions.
