Your Thailand Customs Self-Audit: A Practical Checklist for 2025

- 4 min read
As businesses navigate the complexities of international trade, one aspect that should not be overlooked is the importance of customs compliance. With Thai Customs increasing post-clearance audits and adopting data-driven risk profiling, now is the perfect time to assess your compliance practices. This blog post offers a comprehensive self-audit checklist designed to help you prepare for 2025 and secure your business against potential pitfalls.
Why Self-Audit Now
The landscape of customs regulation is evolving, making self-audits essential for businesses involved in importing and exporting goods. The Thai Customs Department is focusing on key areas such as valuation, HS classification, FTA origin claims, and digital data integrity. Understanding these components can set your company up for success when faced with potential audits.
Data-driven risk profiling is now more prevalent, which means that customs authorities can identify and investigate potential compliance issues with increasing accuracy. By carrying out a self-audit, you can proactively address any discrepancies and ensure your business aligns with the latest regulations.
Moreover, voluntary disclosure routes are available, offering businesses a way to report compliance issues and seek leniency—although standards for these disclosures have tightened. Taking the initiative to self-audit now can mitigate risks and position your company favorably in the eyes of customs officials.
The One-Stop Service Program (OSSP): Use It Wisely
One of the most favorable opportunities available for businesses is the One-Stop Service Program (OSSP). Extended until September 30, 2026, this program provides various voluntary disclosure benefits such as case settlements at headquarters, penalty relief, and reduced monthly surcharge rates, given that you meet the qualifications.
However, the reviews for OSSP applications are becoming stricter starting in 2025. Authorities will closely examine the intent behind the disclosures, the duration of the issues, and the control environment before accepting any applications. If your company has a weak compliance history, this could lead to rejection.
Therefore, it is critical to document compliance processes meticulously and ensure your records are organized to facilitate potential OSSP applications.
The 20-Point Self-Audit (Field-Tested)
To effectively navigate the self-auditing process, here is a 20-point checklist broken down into key categories:
Classification & Valuation
Confirm AHTN 2022 HS for all SKUs: Ensure that you have an updated internal rulings file to manage HS codes.
Tie HS to product specs: Each product should have specific details related to materials and functions, avoiding “basket” headings.
Align transaction value: Capture royalties and assists according to WTO valuation rules for accurate customs declarations.
Origin & Preference
Validate CO forms and PSR tests: Confirm that these documents comply with ASEAN and RCEP claims.
Archive supplier origin declarations: Make sure you have readily accessible manufacturing records for verification purposes.
Licensing & Controlled Goods
Map Permission Goods and agency mandates: Maintain a record of relevant licenses.
Confirm LPI if in FDA scope: Ensure that invoices link correctly with e-Certificates via the Thai National Single Window (NSW).
Reassess materials: Stay updated on regulations regarding the plastic waste import ban and adjust procurement practices accordingly.
Digital Systems & Data Integrity
Reconcile data from various sources: Ensure that your ERP systems, broker data, and e-Customs records align, particularly regarding HS codes, values, and marks.
10. Monitor NSW e-Tracking: Regularly check the status of permits and promptly address any discrepancies.
11. Maintain a document spine: Ensure consistency in documentation from invoices to certificates of origin.
Documents & Carriers
12. Enforce non-blank shipping marks: Consult carrier restrictions to avoid potential holds.
13. Ensure consignee formats meet rules: Verify that your shipping details follow destination regulations or include proper transshipment clauses.
Operational Controls
14. Establish a pre-clearance gate: Catch potential license and origin mismatches before items are cleared.
15. Run quarterly mock audits: Test high-value SKUs regularly to ensure compliance.
16. Keep post-clearance files: Maintain records for quick retrieval over the last 12 to 60 months.
Voluntary Disclosure Readiness (OSSP)
17. Document issue discovery: Keep track of when issues are identified and the root causes behind them.
18. Quantify exposure: Clearly outline any duties or surcharges due to compliance breaches, along with a proposed remediation timeline.
19. Check for disqualifying offenses: Ensure there are no active audits or prosecutions that could impact your application.
20. Submit a robust application: Present a clean application accompanied by a strong compliance narrative.
Final Considerations
Conducting a self-audit can equip your business with the insights necessary to bolster your compliance framework. Integration of these practices can reduce the risk of customs liabilities and prepare you to face audits with confidence. For those interested in leveraging the One-Stop Service Program, being thoroughly prepared is paramount.
One effective approach is to conduct a customs health check, which can be completed in two weeks. From there, you can decide whether the OSSP or a quiet remediation is the best course of action for your situation.
With the regulatory landscape continuously evolving, staying proactive and informed is your best strategy for success in the coming year.
