Claiming lower tariff rates requires a correct Certificate of Origin that meets the verification requirements of the customs authority. Customs offices enforce strict rules to verify your goods qualify under the trade deal, and a mistake on the form can lead to your preference claim being rejected or queried.
How DHL Express supports the paperwork
DHL Express's Multiline Entry and Export Declaration services can support your export documentation. DHL Express supports you with document preparation and handling in line with service requirements, but final compliance remains your responsibility.
Four things every origin file needs
Structure your records around these four checks:
- Check HS Codes: Match your product codes against treaty schedules to verify eligibility.
- Apply Origin Rules: Document exactly how the product qualifies, such as by using wholly obtained materials.
- Complete Forms: Fill in every required box, including exporter details and your origin statement, certified by the competent authority where this is required. In Vietnam, responsibility for issuing certificates of origin returned to the Ministry of Industry and Trade from 5 May 2025 under Decision No. 1103/QD-BCT, and the requirements vary by agreement and origin criterion.
- Keep Production Records: Store all material bills, invoices, and manufacturing logs to back up your claims.
Prepare your files early to avoid bottlenecks during busy seasons. Processing and transit times may vary during peak periods such as Tet Nguyen Dan, which makes early preparation even more important.
How do you protect your business from retroactive fines?
Customs agencies can audit your trade records after a shipment clears the border, and if they find your origin claims were incorrect, they can issue back-tax bills and serious penalties. A clear compliance trail helps you produce the documentation when an audit happens.
How MyDHL+ helps you prepare your shipment information
Automated screening tools in MyDHL+ help you find and fix missing data before you submit files to customs, catching the kind of gap that turns into a problem years later.
Where compliance gaps commonly show up
Review your current trade risk against these common gaps:
Compliance Risk
| Operational Impact
| How to Protect Your Business
|
|---|
Expired Documents
| May trigger additional requests or processing at the border
| Set automatic alerts for treaty certificate expiry dates
|
Incorrect Formulas
| Causes errors in your regional value calculations
| Standardise your bills of materials with updated costs
|
Poor Document Storage
| Leaves you unable to produce proof during an audit
| Keep digital records of all manufacturing logs for the period required under the applicable regulations and trade agreement
|
Wrong HS Codes
| May result in tariff reassessment and further action over misclassification
| Review products regularly against customs updates
|
Failing to track these details can increase the risk of unexpected tax liabilities. Small errors on individual invoices can add up when applied retroactively over a whole year of shipments.
