This course covers Sections 22–25 of the Customs Act 1962, which together form the legal framework for reducing, waiving, or exempting customs duty in specified circumstances. Each section addresses a distinct factual situation — goods damaged before clearance, goods lost or destroyed in the customs area, goods exempted by government notification, and special exemptions in the public interest — and CBLE regularly tests whether candidates can identify the correct provision for a given scenario rather than applying them interchangeably.

Section 22 covers abatement of duty on damaged or deteriorated goods — where goods are damaged before or during unloading, or deteriorate due to any cause beyond the importer's control, the duty is reduced proportionately to reflect the diminished value. The conditions for claiming abatement, the method of calculating the abated duty, the role of the proper officer in assessing the extent of damage, and the distinction between damage occurring before unloading versus after unloading are treated as core CBLE concepts. Section 23 covers remission of duty on goods lost or destroyed — where goods are lost or destroyed in the customs area before OOC, the proper officer may remit the duty entirely — and the course draws the precise distinction between Section 23 remission and Section 13 pilferage since both involve goods lost in the customs area but carry different legal consequences and remedies.

Section 25 — the Central Government's power to exempt goods from customs duty by notification — is the most practically significant provision in this group and is given the most detailed treatment. The course explains the difference between general exemptions (applicable to all importers of specified goods) and special exemptions (granted to a specific importer or class of importers), the legal effect of an exemption notification, the conditions attached to exemptions and the consequences of non-fulfilment of conditions, and the retrospective versus prospective operation of exemption notifications. The interaction between Section 25 exemptions and the duty calculation sequence — where exemptions reduce or eliminate BCD, IGST, or other duty components — is explained with worked examples. Section 25(2) covering ad hoc exemptions in the public interest and the procedure for suo motu exemptions are addressed alongside the CBLE-tested distinction between an exemption notification and a customs duty remission under Section 23.
