Layered customs secondary inspection applies material identification, trace screening and radiation assessment according to the initial indicator and legal procedure.
Customs operations must distinguish routine trade and travel from items requiring secondary inspection without slowing every movement. Risk information and primary screening determine whether officers need material identity, explosive or narcotics trace assessment, radiation investigation or another specialist method.
HT-Nova portable instruments can support these defined secondary-inspection tasks and preserve results for supervisory review.
Cargo, mail, baggage and passengers present different access, packaging and throughput constraints. No one detector can comprehensively clear prohibited goods, and instrument results must remain within the legal search and evidence process.
Move the item, person or vehicle into the appropriate controlled process without unnecessary handling.
Choose radiation, trace, vapor or material-identification tools according to the indicator and operating procedure.
Use trained operators, controlled sampling and method-specific checks rather than a universal detector.
Refer unresolved or hazardous findings to the responsible specialist authority and preserve scene information.
Document alarms, measurements, samples and disposition to support traceability and process improvement.
Raman supports compatible solids and liquids; IMS or fluorescence can support selected trace screening; radiation instruments investigate elevated ionising-radiation response; gas sensors address defined atmospheric concerns rather than every concealed substance.
Field results guide secondary inspection and specialist escalation. They do not replace X-ray or other primary screening, laboratory confirmation, chain of custody or the customs authority's final determination.
The initial indicator determines the next compatible detection method.
Each technology has a defined task, limitation and escalation rule.
Results, samples and disposition remain connected to the inspection record.
