A Sweeping Rewrite of Indonesia's Digital Trade Rules
On June 4, 2026, Indonesia's Minister of Trade Budi Santoso signed Regulation No. 19 of 2026 on Trade Through Electronic Systems ("Permendag 19/2026"), replacing the three-year-old Permendag 31/2023. It took effect June 8, 2026, and the ministry frames it around five pillars: domestic-product visibility, seller legality, platform transparency, consumer protection, and "responsible" use of AI in commerce. For Shopee, TikTok Shop, Tokopedia, and Lazada — plus ride-hailing and online travel apps newly folded into the PMSE (electronic-trade) category — the rule turns marketplaces into deputized enforcers of Indonesian licensing, competition, and consumer law, not just hosts of third-party listings.
Licensing: A Real Problem, A Blunt Instrument
The regulation's core mechanism is the Nomor Induk Berusaha (NIB), Indonesia's unified business ID. Platforms must now reject new sellers who lack one and mark existing unlicensed sellers "Dalam Proses Legalisasi" (in the process of legalization), suspending them if they haven't secured an NIB within 18 months for existing sellers or 6 months for new ones — a deadline running through roughly December 2027. Minister Santoso has asked platforms to "inform, assist, and connect" sellers to the government's free OSS registration portal.
The steelman here is straightforward: Indonesia's e-commerce sector is enormous and substantially informal, and unlicensed sellers routinely sidestep consumer-protection rules, tax collection, and counterfeit enforcement that licensed competitors must follow. A verified-seller floor isn't unusual — the EU's Digital Services Act imposes comparable "know your business customer" duties on marketplaces. But deputizing platforms as the licensing gate, rather than having the government verify sellers directly, pushes compliance cost and liability risk onto companies with no enforcement mandate of their own — and risks locking out the marginal micro-sellers the rule claims to protect during the transition.
The Domestic-Ranking Mandate: Industrial Policy Without a Mechanism
More unusual is the requirement that "search, recommendation, and ranking systems prioritize the display of domestic products" at the top of platform homepages. Facing criticism that this amounted to algorithm regulation, government spokesperson Kurnia Ramadhana clarified on July 15, 2026 that the rule does not dictate which algorithm or technology platforms use — only the outcome: domestic and MSME products must surface prominently, with each platform free to choose its own technical method.
"Pemerintah masih memberikan keleluasaan kepada masing-masing platform untuk menentukan mekanisme teknis sesuai karakteristik platformnya" — the government leaves platforms discretion over technical mechanism, so long as the visibility outcome is met.
That flexibility is framed as a concession to platforms, but it cuts the other way too: an outcome-based mandate with no defined measurement standard is hard for any company to audit against and easy for a regulator to enforce selectively. Favoring domestic goods in search results is a familiar instinct in digital-market policy, but it sits awkwardly next to WTO national-treatment norms, and it substitutes a ranking mandate for the more defensible tools already in the same regulation — faster licensing, IP verification, origin disclosure.
AI Disclosure and a Three-Day Reporting Trigger
Permendag 19/2026 also requires platforms to disclose when listings, recommendations, or promotions are AI-generated or AI-influenced, and to maintain "risk-proportionate" AI governance plus a complaint channel — Indonesia's first trade-level AI transparency rule. The instinct tracks a defensible global trend (the EU AI Act's transparency duties for synthetic content): consumers shopping an AI-ranked feed have a real interest in knowing it's AI-ranked. The problem is execution — the ministry has not prescribed a disclosure format, leaving platforms to guess at compliance on a rule already in force.
Separately, platforms must flag suspected unfair-pricing or anti-competitive conduct to authorities within three business days of discovering it. Combined with the licensing gate, this makes marketplaces first-line investigators for competition law, not just infrastructure — workable if paired with clear evidentiary standards and safe-harbor protection for good-faith reports, neither of which the ministry has yet published.
The Missing Piece Is Implementing Guidance
None of this makes Permendag 19/2026 illegitimate. Seller verification, AI transparency, and platform accountability for anti-competitive pricing are all reasonable regulatory goals, and Indonesia's Directorate General of Consumer Protection and Trade Order says it will police compliance through complaints and clarifications rather than blanket audits — a proportionate enforcement posture on paper. But the rule leans heavily on platforms to fill in mechanism where the ministry has specified only outcome: rank local products higher (measured how?), disclose AI use (in what format?), report violations within three days (against what evidentiary bar?).
For a regulation already in force — with a legalization clock running toward late 2027 — that gap matters more than the headline provisions. Indonesia should publish technical implementing guidance specifying measurement standards for the ranking mandate and a disclosure template for AI content before the compliance deadlines bite, rather than leaving platforms, sellers, and eventually courts to reverse-engineer the standard from enforcement actions.
