1. The purpose
A documentation agent handles the Chinese side of export paperwork: certificates of origin, notarization, authentication, legalization, translation, courier.
The service is worth paying for where the exporter’s volume is low, the destinations are varied, or the destination requires consular legalization the exporter has not handled before.
2. The selection criteria
Scope
Does the agent handle the whole chain, or only certificates of origin?
Some agents issue certificates of origin and nothing else. Where legalization is needed, a different capability is required.
Destination experience
An agent who handles Middle Eastern consular legalization weekly is a different proposition from one who has done it twice.
Ask which destinations they handle regularly, and ask for the specific requirements of two of them.
Notary relationships
Notarization is the step that most often fails. An agent with established notary relationships and knowledge of which notaries handle foreign-related work is materially better.
Translation capability
Whether they have in-house or reliable partner translation, and whether they can certify.
Courier and tracking
Whether they handle courier to the embassy and back, and whether tracking is provided.
Response time
Ask a specific question by email and measure the reply. The agent’s responsiveness before the contract is the responsiveness after.
3. The fee structure
Three common models.
Per document.
Per shipment.
Retainer plus per document.
The third is usually best for a regular exporter.
Watch for disbursements billed separately from fees: notary charges, government fees, embassy charges, translation, courier. These should be itemized.
4. What the agent cannot do
An agent cannot make a document that does not meet the requirements acceptable.
An agent cannot resolve a customs classification.
An agent cannot substitute for the exporter’s own understanding of what the destination requires.
The good agents tell you this. The bad ones promise to handle everything.
5. The specific questions to ask
Can you describe the legalization chain for a commercial invoice to [destination]?
Which documents in that chain do you handle, and which need a third party?
What is your typical turnaround, and what are the current lead times?
How do you handle a document returned by the embassy?
Can you provide references from exporters in my sector?
What are your disbursements, itemized?
6. The warning signs
Promises of a fixed timeline regardless of the destination.
No itemized disbursements.
Reluctance to identify which steps they perform themselves.
No willingness to explain the requirement, only to execute it.
A price materially below the market.
7. The relationship management
Where the agent is good, treat them as a source of information rather than an order-taking service.
Ask them what destinations have changed requirements recently.
Tell them your shipment schedule in advance so they can sequence the work.
Review the itemized disbursements periodically.
8. The cost calculus
For an exporter shipping to consular destinations regularly, the agent’s fee is usually less than the cost of the errors an inexperienced exporter makes.
For an exporter shipping only to Hague parties, the chain is short enough that in-house handling is viable.
9. Closing view
The right agent is one who tells you what the requirement is and what the chain looks like, not one who promises to handle it.
The second type charges less and costs more.
