Single Window clearance: streamlined ADC referrals via declarations and PEC identification to expedite customs release. Amendments under the Single Window project require importers and brokers to identify PEC listed chemical items and declare non pharmaceutical grade or API free dual use items and their non medicinal end use in the Integrated Declaration to avoid ADC referral; risk based sampling, avoidance of repeat batch sampling, digital substitution of declarations and mapping of ADCs to ICES locations are provided to streamline customs and ADC interactions.
