COMMON CUSTOMS DECLARATION ERRORS AND HOW TO AVOID THEM

Customs declaration is a critical step in the import and export process. However, it is also one of the most error-prone stages, as it involves various complex elements such as product codes, documentation, electronic systems, and legal regulations. Even minor mistakes can lead to serious consequences: delays in clearance, increased storage costs, penalties, or even confiscation of goods.

This article outlines the most common customs declaration errors, explains their causes and risks, and provides practical solutions to help businesses avoid issues and streamline their logistics operations.

Incorrect HS Code Classification

What is an HS Code?

The Harmonized System (HS) Code is an international classification system that assigns codes to goods for import/export purposes. Each code corresponds to a specific group of products and determines the applicable tariff.

Common Errors:

• Choosing an HS code that does not match the nature of the goods

• Using overly generic codes to avoid high tariffs

• Not updating the HS codes in line with current customs regulations

Risks:

• Customs authorities may require a reassessment, causing clearance delays

• Risk of back taxes, penalties, and fines

• Ineligibility for tariff preferences under trade agreements

Solutions:

• Use official customs portals or ECUS systems to accurately look up HS codes

• Provide technical documents, photos, or product samples to clearly define the product

• If unsure, request a prior classification ruling from customs authorities to avoid disputes

Incorrect Importer/Exporter Information

Common Errors:

• Entering wrong company name, address, or tax code

• Confusing importer, consignee, and buyer information

• Incorrect account number in financial records

Risks:

• Declaration inconsistencies with commercial documents

• Delays in processing and possible rejection of the declaration

• Legal liability and difficulties in dispute resolution

Solutions:

• Double-check all company details before submission

• Ensure consistency across all documents: Invoice, Packing List, Contract, and Bill of Lading

• Use a CRM system to store and auto-fill verified client data

Incorrect Customs Value Declaration

What is Customs Value?

It’s the declared value of goods used to calculate import duties and VAT, usually based on the FOB or CIF price depending on Incoterms.

Common Errors:

• Omitting relevant costs such as freight, insurance, or port charges

• Confusing commercial value with customs valuation

• Misstating Incoterms (e.g., using FOB instead of CIF)

Risks:

• Additional tax assessment or fines

• Difficulties in tax refunds or applying for preferential tariffs

Solutions:

• Cross-check contract, invoice, and shipping documents to identify full costs

• Determine Incoterms correctly and itemize associated charges

• Consult with logistics experts to ensure an accurate customs value

Missing or Incorrect Documentation

Common Errors:

• Missing essential documents: C/O (Certificate of Origin), CQ (Certificate of Quality), import licenses, etc.

• Inconsistencies in product description, quantity, or unit of measure

• Low-quality scanned files or wrong file formats

Risks:

• Customs clearance denied

• Loss of tax benefits even if eligible

• Storage or demurrage charges due to cargo hold

Solutions:

• Use a checklist of required documents for each type of shipment

• Request suppliers to send valid and correct documents in advance

• Use digital document management systems for version control and accuracy

Errors in Quantity or Unit of Measure

Common Errors:

• Confusing units (e.g., declaring 1,000 kg instead of 1,000 pcs)

• Quantity declared doesn’t match the Packing List

• Inconsistent units across the declaration and attached documents

Risks:

• Triggers suspicion of fraud → leads to physical inspection

• Clearance delays and operational disruptions

Solutions:

• Carefully compare the Invoice, Packing List, and Bill of Lading

• Use standard data entry templates and internal cross-checking procedures

• Weigh and count goods upon arrival to correct errors promptly

Not Updating Product-Specific Policies or Licenses

Common Errors:

• Unaware that goods require import permits or are under special regulation

• Mistakenly classifying regulated goods as non-regulated

• Obtaining the wrong license or submitting it to the wrong authority

Risks:

• Customs may reject clearance or require re-export

• Cargo stuck at port → leads to high storage or demurrage fees

Solutions:

• Use the National Single Window portal or customs websites to verify product policies

• Consult with customs officers or compliance experts in advance

• Regularly monitor legal updates (circulars, decrees, guidance notes)

Errors in E-Declaration or Software Incompatibility

Common Errors:

• Using outdated software not compatible with VNACCS/VCIS

• Selecting the wrong declaration type (e.g., E11, A11, B11…)

• Transmission errors or incorrect file formats

Risks:

• Declaration rejected by the system

• Time lost in resubmission or troubleshooting

• Disruptions in delivery schedules

Solutions:

• Always use the latest customs declaration software from reputable providers

• Provide regular training for staff on system use and updated procedures

• Apply internal checklists and peer review before submitting declarations
