Failure to produce required documents during a Post-Clearance Audit is a criminal violation punishable by a fine not exceeding 50,000 THB under Section 202. More importantly, lacking primary trade documents permits customs auditors to reject the originally declared values and apply alternative valuation methods, leading to severe retroactive tax assessments and penalty surcharges.
