Bills of Materials<br \/>\nThese demonstrate precisely which components were incorporated into each finished product.<br \/>\n2. Manufacturing Records<br \/>\nAuthorities frequently wish to understand what manufacturing actually occurred in Vietnam.<br \/>\n3. Supplier Documentation<br \/>\nThe origin and commercial history of imported components should be traceable.<br \/>\n4. Customs Documentation<br \/>\nImport and export declarations should remain consistent with operational records.<br \/>\n5. Internal Procedures<br \/>\nCompanies should be able to demonstrate that compliance forms part of normal business operations.<br \/>\nCommon Findings During Customs Audits<br \/>\nExperience shows that audit findings frequently involve:<br \/>\n\u2022\tinconsistent documentation;<br \/>\n\u2022\tincorrect tariff classification;<br \/>\n\u2022\tincomplete production records;<br \/>\n\u2022\tinsufficient origin evidence;<br \/>\n\u2022\tdiscrepancies between commercial documents and customs declarations;<br \/>\n\u2022\tpoor inventory reconciliation.<br \/>\nInterestingly, many issues arise from documentation rather than intentional misconduct.<br \/>\nHow Should Companies Prepare?<br \/>\nPreparation should become part of ordinary business management.<br \/>\nI generally recommend:<br \/>\n\u2022\tperiodic internal customs reviews;<br \/>\n\u2022\tindependent verification of HS classifications;<br \/>\n\u2022\tregular origin reviews;<br \/>\n\u2022\tdocumentation audits;<br \/>\n\u2022\tsupplier compliance reviews;<br \/>\n\u2022\temployee training.<br \/>\nWaiting until an audit begins is usually too late.<br \/>\nAudits Can Also Be Opportunities<br \/>\nA well-managed audit allows a company to demonstrate the strength of its compliance systems.<br \/>\nCompanies that maintain accurate records and transparent procedures often complete audits efficiently and continue operations with minimal disruption.<br \/>\nPreparation therefore protects both legal compliance and commercial continuity.<br \/>\nFinal Thoughts<br \/>\nManufacturing excellence depends upon precision.<br \/>\nThe same principle applies to customs compliance.<br \/>\nThe companies that consistently succeed in Vietnam are not necessarily those with the largest legal departments.<br \/>\nThey are those that recognise that customs compliance is part of operational excellence.<br \/>\nGood documentation.<br \/>\nGood procedures.<br \/>\nGood governance.<br \/>\nThose three principles remain the strongest preparation for any customs audit.<br \/>\nUltimately, the best customs audit is the one for which your company has already prepared\u2014long before the authorities arrive.<br \/>\n***<br \/>\nFor more information on the above, please do not hesitate to contact the author Dr. Oliver Massmann under omassmann@duanemorris.com.
