Tanjung Priok, serving Jakarta, is Indonesia's primary gateway for China-origin cargo, though the country's archipelago geography means goods destined beyond greater Jakarta frequently need a further domestic sea or road leg after the main port call — a detail that should factor into total transit time planning rather than treating port arrival as equivalent to final delivery.
Indonesia requires an API (Angka Pengenal Importir) import licence to bring goods in commercially, issued to the Indonesian importer of record rather than tied to any specific shipment — this needs to be in place before the first commercial import, and is a registration step entirely separate from the customs declaration itself.
Certain product categories carry additional pre-shipment or post-arrival verification requirements beyond the standard customs process, and import licensing can be product-specific as well as importer-specific for some categories, which makes confirming the exact licensing pathway for a given product worth doing before committing to an order rather than after goods are produced.
ACFTA preferential tariff treatment, as with Thailand, is available for many categories on Chinese-origin goods entering Indonesia, subject to the same Form E Certificate of Origin requirement.
