Export fraud: forged supervision reports used to misdeclare coloured water as printing ink to obtain DEPB benefits via false exports. Export transactions were manipulated to secure undue benefits under the DEPB scheme by falsely presenting coloured water as industrial printing ink and using forged documents purporting Central Excise supervision. Containers were held in local storage and later stuffed at peripheral yards with coloured water misdeclared as printing ink, and forged examination reports were used to substantiate export consignments and obtain shipping clearance.
