During customs procedures, many businesses receive a notice requesting supplementary documents from the Customs authority. This is a fairly common situation, especially for shipments subject to document checks, specialized inspection or information that needs further verification. If handled slowly or with incomplete documentation, a business may face delayed clearance, additional storage, yard and container fees, and disruption to its delivery schedule.
So what steps should a business take when Customs requests supplementary documents? The article below provides a detailed guide to the handling process and the key points for minimizing risk.
When Does Customs Request Supplementary Documents?
During document review, the Customs authority may ask a business to submit additional documents when:
- The declaration documentation is incomplete.
- Information across documents is inconsistent.
- The declared value needs to be verified.
- The HS code needs to be clarified.
- A specialized license or document is missing.
- There is doubt about the origin of the goods.
- The documentation does not yet meet current legal requirements.
A request for supplementary documents does not mean the business has committed a violation; it is intended to ensure the declared information is accurate before clearance.
Documents Commonly Requested
Depending on the type of goods and the specific case, Customs may request supplementary:
- Commercial Invoice.
- Packing List.
- Foreign trade contract.
- Bill of Lading or Air Waybill.
- Certificate of Origin (C/O).
- Product catalogue.
- Technical specification sheet.
- Quotation or sales contract.
- Payment documents.
- Import license.
- Quarantine certificate.
- Quality inspection results.
- Documents related to value or HS code.
Businesses need to identify exactly which documents are requested so they can prepare them in full and avoid multiple rounds of submission.
The Process for Handling a Customs Request for Supplementary Documents
Step 1: Receive the Notice from Customs
The notice may be sent through:
- The electronic customs declaration system.
- The Customs officer in charge of the file.
- The customs broker or Freight Forwarder.
Businesses need to read the content carefully to identify:
- The documents to be supplemented.
- The points requiring explanation.
- The submission deadline.
- The method of submission.
Step 2: Check and Cross-Reference the Documents
- After receiving the notice, review the entire document set: Commercial Invoice, Packing List, Bill of Lading, contract, customs declaration, C/O, payment documents.
- At the same time, check: product name, HS code, quantity, weight, value, delivery terms (Incoterms), and buyer and seller information.
A careful cross-check helps detect discrepancies before resubmitting to Customs.
Step 3: Prepare the Supplementary Documents
Depending on the Customs request, businesses need to prepare:
- Originals or copies as required.
- Explanatory documents.
- Technical documentation.
- Certificates from the manufacturer.
- Documents proving the transaction value.
- Any missing licenses.
If the documents are in a foreign language, translation may be required as requested by the competent authority.
Step 4: Draft an Explanatory Letter (If Needed)
In many cases, businesses need to draft an explanatory letter to clarify:
- The reason for discrepancies between documents.
- The basis for determining the HS code.
- The method used to determine the customs value.
- The origin of the goods.
- Other matters related to the documentation.
The letter should be clear, concise and accompanied by supporting documents.
Step 5: Submit the Documents on Time
Once complete, businesses must submit the documents by the deadline set by Customs. Late submission can lead to:
- Prolonged clearance time.
- Additional storage and yard fees.
- Disruption to the delivery schedule.
- An increased risk of further inspection.
Step 6: Coordinate with Customs During Processing
After receiving the documents, Customs may:
- Request further information.
- Ask for a direct explanation.
- Physically inspect the goods.
- Conduct a value consultation.
- Verify the HS code.
Businesses should proactively cooperate and respond quickly to shorten the processing time.
Step 7: Complete Clearance
Once the documentation is approved and all requirements are met, Customs continues processing the declaration so the goods can be cleared. Businesses should retain all documents for post-clearance audits or future cross-checking as needed.
Common Reasons Customs Requests Supplementary Documents
Incomplete documentation
The submitted documentation is missing:
- The Commercial Invoice.
- The Packing List.
- The C/O.
- A specialized license.
Inconsistent information
- Wrong quantity.
- Wrong weight.
- Wrong product name.
- Wrong delivery terms.
- Wrong unit of measure.
Incorrect HS code
Applying the wrong HS code can affect:
- The tax rate.
- The goods management policy.
- Import conditions.
Value declaration not appropriate
If the declared value is far lower than the reference data, Customs may ask the business to provide supporting documents.
Goods subject to specialized management
Some goods require: quarantine, quality inspection, an import license, conformity certification, and more. If these are incomplete, the documentation will not be accepted.
Mistakes Businesses Should Avoid
Many businesses prolong the processing time because they:
- Do not read the Customs request carefully.
- Submit incomplete documents.
- Send the wrong version of a document.
- Fail to explain matters clearly.
- Respond slowly.
- Do not cross-check documents before submitting.
These mistakes can force documentation to be supplemented multiple times, increasing costs and affecting the delivery schedule.
Tips to Reduce Supplementary Document Requests
To reduce the risk of being asked for supplementary documents, businesses should:
- Prepare complete documentation before declaring.
- Check consistency across all documents.
- Apply the correct HS code.
- Declare truthfully and accurately.
- Have catalogues and technical documents ready for special goods.
- Keep up with new customs and specialized management regulations.
- Work with an experienced customs broker or Freight Forwarder.
Standardizing internal processes significantly reduces processing time and limits additional costs.
