04 How we work

The journey of a declaration.

  1. 01

    Pre-assessment

    HS code, origin, duty burden and required permits are settled before anything moves. Surprises are solved at the desk, not at the border.

  2. 02

    Documents & digital file

    Invoice, bill of lading, packing list and origin documents are checked and gathered into a single digital file.

  3. 03

    Declaration & registration

    The declaration is lodged electronically in the BİLGE customs system and registered; duties and payments are tracked.

  4. 04

    Inspection lane

    Risk analysis assigns the lane: green, blue, yellow or red. Whatever the outcome, our team is on the ground.

  5. 05

    Release & e-archive

    Goods are released; every document is archived electronically and time-stamped in Denk Online.
