License validity rules: customs broker licences deemed invalid after prolonged inactivity; renewal requires application, eligibility and fee. The amendments permit surrender of a customs broker licence by written request to the issuing Principal Commissioner/Commissioner, who may revoke the licence after confirming payment of all dues and absence of pending proceedings. Licences remain valid until revoked but are deemed invalid if the licencee is inactive-defined as no customs business for one year. A deemed-invalid licence may be renewed by application in Form I, subject to eligibility checks and payment of a renewal fee. Forms are amended to require disclosure of penalisation, conviction or prosecution under specified fiscal laws.
