In import-export operations, “customs inspection”, “yellow lane”, “red lane” and “manual inspection” are often used interchangeably, causing the wrong resources to be prepared. A document check reviews declared data, supporting evidence, goods-management rules and tax treatment. A physical inspection compares the actual shipment with the dossier by visual examination, package opening, weighing, measurement, scanning or other technical means. Confusing the two may leave a company with perfect paperwork but no terminal and labour booking, or move a container for inspection when the actual issue is an unclear description, HS classification, customs value or licence. This article separates the objects, methods, evidence, results and operational controls for each inspection type.

Updated: 17 July 2026 | Scope: export and import goods undergoing customs procedures in Vietnam

QUICK FACTS

Document check

Compares the declaration with supporting documents, goods-management rules, tax rules and other applicable requirements; it may be performed electronically or by an officer.

Physical inspection

Compares the actual cargo with the customs dossier, including description, tariff classification indicators, quantity, weight or mass, quality, origin and customs-value facts.

Not two names for the same step

A document check acts on data and evidence; a physical inspection directly affects cargo handling, inspection location, seals, packages and delivery planning.

They may follow one another

Document findings, risk analysis or new information may trigger physical inspection or a change in inspection method and scope.

Separate from specialised inspection

Sectoral inspection assesses technical, quality, quarantine or safety requirements under specialised law and does not replace customs inspection.

SCOPE OF APPLICATION

This article applies to export and import goods undergoing customs procedures in Vietnam, including commercial shipments by sea, air, road and rail. It is intended for trade compliance, purchasing, logistics, tax/accounting, warehouse teams and customs brokers.

It addresses inspection during the customs procedure for a declaration/shipment. It does not replace guidance on post-clearance audit, inspection at production premises or sectoral inspection.

Operating principle: customs inspection decisions are based on risk analysis and relevant information. Lane colours are a common operational indicator, while the formal system instruction and customs decision control the actual work.

KEY TERMINOLOGY

Term	Meaning	Operational role
Customs document/dossier check	Review of the accuracy, completeness and consistency of the declaration against the customs dossier.	Determines whether the declared data, goods policy, tax, origin and value evidence provide a sufficient basis for processing.
Physical cargo inspection	Examination of the actual goods and comparison with the customs dossier.	Verifies whether the goods actually match the declared description, tariff indicators, quantity, weight or mass, quality, origin and other material facts.
Manual inspection / “kiem hoa”	Common Vietnamese operational shorthand for physical cargo inspection.	It should not be used for document review or sectoral inspection.
Non-intrusive inspection	Inspection by scanner or other technical equipment without initially opening cargo.	It may form part of physical inspection and may or may not lead to manual opening.
Risk management	Analysis and assessment used to determine customs control.	Supports selection of document or physical inspection and later changes when new risk information arises.
Specialised inspection	Inspection under laws on quality, health, culture, quarantine, food safety or another regulated sector.	Its result may be a clearance condition, but the competent authority, purpose and dossier differ from customs inspection.
Inspection result	System/officer record of what was checked and how the case is concluded.	Supports acceptance, document supplementation, amendment, sampling, expert assessment or other handling.

NATURE AND OPERATING MECHANISM

A document check answers: “Are the declared data complete, consistent and legally supportable?” A physical inspection answers: “Do the goods inside the packages or container actually match the declaration?”

The layers are connected. The dossier provides the comparison standard for physical inspection, while the cargo provides evidence confirming or contradicting the declaration. Good-looking documents that do not reflect the goods remain high-risk; correct goods with an incomplete or inaccurate dossier may still lack a legal basis for processing.

Decision mechanism: Article 31 of the Customs Law provides that the customs office handling the dossier uses risk analysis and relevant information to decide document and physical inspection.

COMPARISON OF THE TWO INSPECTION TYPES

Criterion	Customs document check	Physical cargo inspection	Business control point
Object	Customs declaration and supporting documents.	Cargo, packaging, packages, container, seal and physical indicators.	Documents must describe the actual goods accurately.
Purpose	Test accuracy, completeness, consistency and legal compliance.	Establish the legality and consistency of the shipment with its dossier.	Avoid separate “paper data” and “warehouse reality”.
Method	Electronic customs data system or direct review by an officer.	Direct examination, scanner, technical equipment or other customs measures.	Prepare electronic evidence and an operational inspection plan.
Cargo presence	Full presentation or opening of cargo is generally not required solely for document review.	Cargo must be brought to the inspection location; the declarant or legal representative is normally present, subject to statutory exceptions.	Reserve terminal, warehouse, truck, labour and authorised representative.
Operational cost	Mainly time for evidence, translation, clarification and technical documentation.	May involve shifting, lifting, opening/repacking, labour, storage, scanning, sampling and truck waiting.	Separate physical-inspection operations from customs brokerage fees.
Possible outcome	Accepted; clarification or supplementation; amendment; escalation to another control step.	Matched; discrepancy; expanded scope; sampling/expert assessment; handling of misdeclaration or violation.	Archive every request, reply and inspection record by declaration/container.
Schedule impact	Depends on response time and policy complexity.	Depends on inspection site, cargo condition, equipment, scope and findings.	Do not promise warehouse delivery based only on “documents submitted”.

WHAT IS CHECKED AT EACH LAYER

1. DOCUMENT LAYER – DATA AND GOODS POLICY

Document-check data group	Fields that should reconcile	Evidence source	Risk if inconsistent
Goods identification	Description, model, construction, use, brand, proposed HS code.	Invoice, catalogue, datasheet, contract and model list.	Request for revised description, technical evidence or classification/policy review.
Quantity and weight	Packages, units, gross/net weight and commercial quantity.	Packing List, transport document, weighing record and manifest.	Data discrepancy and difficulty during physical inspection.
Value and delivery terms	Unit price, total value, currency, Incoterms, freight, insurance and adjustments.	Contract, Invoice, freight/insurance and payment evidence.	Customs value clarification or additional documents.
Origin	Declared origin, origin criterion and certificate reference.	C/O, origin declaration and production evidence where applicable.	Preference may be denied or verification requested.
Goods-management policy	Licence, specialised-inspection registration, labelling and import conditions.	Sectoral law, permit and National Single Window result.	Cargo may not yet qualify for clearance.
Shipment identity	B/L or AWB number, container, seal, port and mode.	Transport document, Arrival Notice, EIR and manifest.	Wrong-shipment matching, delivery or data-amendment problems.

2. PHYSICAL LAYER – GOODS AND MATERIAL INDICATORS

Physical verification item	Common method	Evidence to prepare	Indicator for broader inspection
Description and tariff indicators	Visual examination, package opening, model/serial comparison.	Catalogue, cargo photos and model matrix.	Mixed cargo, generic description or undeclared models.
Classification characteristics	Check construction, material and function; sampling/expert assessment where required.	Datasheet, BOM, manual, sample and prior analysis.	Actual characteristics differ from the technical file.
Quantity, weight and volume	Package count, weighing, measurement or inspection of the selected portion.	Detailed Packing List, weight ticket and stowage plan.	Abnormal seal/package, count mismatch or significant weight variance.
Origin and marking	Observe marks, packaging and production indicators.	C/O, original label and production records where needed.	Conflicting country mark, missing label or inconsistent processing.
Quality and condition	Observation, specification check or coordinated sampling as applicable.	COA, test report and specialised-inspection evidence.	Damage, different grade or safety concern.
Commercial identity/value facts	Compare grade, accessories and composition with the declared price.	Price list, contract, catalogue and cost build-up.	Higher-grade goods, undeclared accessories or unusual bundled items.

RELATIONSHIP WITH LANE ASSIGNMENT AND RISK MANAGEMENT

Common operational lane/status	Primary control layer	Can cargo be scanned/opened?	Important note
Green lane	Normally processed at a level exempting detailed dossier and physical inspection under the decision at that time.	Not as a default, but the decision can change if risk information or violation indicators arise.	Green is not a permanent immunity from customs control.
Yellow lane	Usually focuses on customs document review.	Not necessarily immediately; physical inspection may follow if the dossier is insufficient or new information arises.	Prepare technical clarification and source documents before an officer requests them.
Red lane	Usually combines document review and physical inspection under the customs decision.	Yes; method may be scanning, direct examination or a combination.	Lock the site, timing, labour, transport and representative.
Changed control level	Triggered by new information, indicators or preliminary findings.	The case may escalate from document to physical inspection or change method/scope.	Follow the formal system instruction, not colour terminology alone.

This matrix reflects common operations. Always follow the instruction issued for the specific declaration.

DOCUMENTS AND DATA TO PREPARE

Document/data	Prepared/issued by	Use in document check	Use in physical inspection
Customs declaration	Declarant	Central reference for all declared criteria.	Benchmark for comparing actual description, code indicators, quantity, origin and value facts.
Commercial Invoice & Contract	Seller/buyer	Transaction, value and delivery terms.	Compare grade, accessories, model and commercial quantity.
Packing List	Seller/packer	Packages, weight and packing configuration.	Select packages, count, weigh, open and repack.
B/L or AWB	Carrier/forwarder	Shipment, route and container/package identity.	Identify the correct shipment, container, seal and location.
Catalogue/Datasheet/Manual	Manufacturer/supplier	Explain description, use, construction and HS rationale.	Compare model, specification, material and function.
C/O, permits and sectoral results	Competent issuer	Origin and goods-policy compliance.	Compare marks, characteristics and samples where relevant.
Loading photos, container map and seal record	Supplier/warehouse/carrier	Supporting shipment explanation.	Locate target packages and evidence pre-inspection condition.
Inspection record/result	Customs and witnessing parties where applicable	Audit trail for document handling.	Records scope, method, findings and discrepancies.

PROCESS AND CONTROL TIMELINE

Step	Input	Main action	Controlled output
1. Receive control decision	Lane/result/system instruction.	Identify document, physical or combined inspection and read the specific request.	Owner, deadline, site, evidence list and operations plan.
2. Pre-review the dossier	Declaration, Invoice, Packing List, transport document, permit and technical file.	Cross-check description, model, quantity, value, origin, container and seal.	Consistent dossier and clarification list.
3. Respond to document review	Officer/system request.	Submit evidence, explain, amend or supplement as applicable.	Request closed or next-control decision identified.
4. Prepare physical inspection	Inspection decision, site and cargo status.	Book shifting/lifting/scanning; arrange representative, labour and tools.	Correct cargo ready at the authorised site with traceability preserved.
5. Perform verification	Actual goods, dossier and technical evidence.	Scan, open, count/weigh/measure, compare model/mark/construction and sample if instructed.	Recorded scope, packages checked, seals and findings.
6. Handle the result	Conclusion and any discrepancy.	Explain, amend, pay additional liabilities, obtain expert assessment or comply with enforcement as applicable.	Clear status and outstanding obligations.
7. Close the audit trail	Record, photos, EIR, weight ticket and correspondence.	Archive by shipment/container and record the root cause.	Evidence for reconciliation, post-clearance review and data improvement.

HOW TO HANDLE INSPECTION RESULTS

Result	Meaning	Appropriate action	Avoid
Dossier accepted	Documents provide a sufficient basis at the dossier-review layer.	Monitor the next status and complete tax/sectoral obligations.	Assuming the cargo can never be selected later.
Supplement/clarification requested	Customs lacks a sufficient basis from the current file.	Answer the exact question with controlled source documents.	Submitting unrelated documents or changing description inconsistently.
Escalated to physical inspection	Actual cargo must be verified or a risk factor clarified.	Lock operational arrangements and prepare target models/packages.	Preparing only paperwork without cargo access and representative.
Actual cargo matches dossier	No discrepancy identified within the inspected scope.	Complete the next procedural step and retain the inspection evidence.	Ignoring seal, opened-package and cargo-condition records.
Discrepancy needs further verification	Facts are not yet sufficient for a final conclusion.	Support sampling, expert assessment and technical/value evidence.	Moving or altering goods, packaging or seals without authority.
Misdeclaration/violation established	The dossier or actual cargo is non-compliant.	Amend, pay, remedy or comply with the competent decision.	Relying on verbal arrangements or failing to preserve root-cause evidence.

RISKS AND COMMON ERRORS

Common error	Cause	Impact	Control
Generic Invoice description	Supplier uses “parts/accessories” or commercial shorthand.	Classification/policy uncertainty and technical-evidence request.	Require material, construction, function and model.
Packing List lacks package map	Mixed cargo and many SKUs.	More packages opened and longer inspection.	Prepare model-to-carton/container mapping.
Technical file does not match model	Supplier provides a family catalogue only.	Potential classification or function discrepancy.	Lock the exact model and document revision.
Paperwork ready, site not ready	No inspection-operations owner.	Shifting delay, labour shortage, storage and truck waiting.	Create RACI across broker, terminal, truck, warehouse and representative.
Sectoral check confused with customs inspection	Authorities and purposes are not separated.	One workstream remains incomplete although the other is finished.	Track two workstreams and link results only where required.
Seal/package changed without record	Multiple handovers.	Weak evidence of cargo condition and discrepancy scope.	Keep photos, seal record, EIR and handover minutes.
Inspection scope not precisely recorded	Photos/minutes not linked to packages/models.	Harder explanation during escalation or post-clearance review.	Code evidence by container–seal–carton–SKU–timestamp.
Yellow lane treated as guaranteed no inspection	Colour is treated as final instead of the formal decision.	Unprepared if customs changes the control level.	Monitor system instructions until procedure completion.

FREQUENTLY ASKED QUESTIONS

Does a document check require opening the container?

Not by default. It focuses on the declaration and evidence. Cargo is shifted, scanned or opened only under the relevant physical-inspection or operational instruction.

Can a yellow-lane declaration be escalated to physical inspection?

Yes. Customs may change the inspection decision when documents are insufficient, new risk information arises or a fact needs verification.

Does red lane mean every package must be opened?

Not necessarily. Customs decides the method and scope; scanning, direct examination, selected-part inspection or broader inspection may be used until there is a sufficient basis for the shipment.

Is scanning the same as manual inspection?

Scanning is a non-intrusive technical measure that may form part of physical inspection. The image result may be sufficient or may lead to manual opening.

Does a completed specialised inspection exempt customs physical inspection?

Not automatically. The two controls have different legal purposes and authorities. A sectoral result may be a clearance condition but does not replace customs risk decisions.

Who attends a physical inspection?

The declarant or legal representative is normally present after registration and presentation of goods, except statutory cases under Article 34 of the Customs Law.

Can the declaration simply be amended when goods differ?

Amendment depends on the timing, discrepancy and inspection status. Follow the formal customs instruction and do not alter cargo or documents to conceal the difference.
