Jobbing under Duty Exemption Scheme now subject to prescribed customs procedure and bond requirements for cottage industry work. Amendment requires that jobbing operations under the Duty Exemption Scheme follow the prescribed customs procedure for concessional import of capital goods used in manufacture of excisable goods rather than being carried out in a warehouse under Section 65. Where jobbing is undertaken by or through cottage or household industry at unspecified locations, the importer must execute a bond with surety or security to ensure compliance; customs will permit clearance subject to sampling, testing, and verification of imported material in resultant exported products, supported by declarations and consumption accounts.
