Indonesia Introduces THAC for Tissue Packaging Lines from Q3 2026

At the conclusion of the Global Paper & Packaging Exhibition (GPPE) in Jakarta on May 27, 2026, Indonesia announced a new mandatory compliance requirement for imported tissue packaging lines—effective Q3 2026—significantly impacting global suppliers serving the Southeast Asian hygiene products market.

New Tropical Humidity Certification Mandated for Importers

On May 27, 2026, the closing day of GPPE Jakarta, Indonesian authorities confirmed that all imported tissue packaging lines must obtain the newly established Tropical High-humidity Environment Operation Certification (THAC) starting Q3 2026. The certification—jointly administered by the Indonesian National Standardization Agency (BSN) and SGS—evaluates three critical technical parameters: moisture resistance of heat-seal adhesives, PLC-based thermal drift compensation algorithms, and salt-spray corrosion resistance ratings for stainless-steel components. As of the announcement, no third-party certification body based in China has been authorized to issue THAC.

Impact Across the Supply Chain

Export-oriented equipment manufacturers

Manufacturers exporting tissue packaging lines to Indonesia must now redesign or validate core subsystems—including sealing modules and control logic—to meet THAC’s environmental performance criteria. Product certification will become a prerequisite before customs clearance or tender participation, directly affecting order fulfillment timelines and after-sales service frameworks.

Raw material and component suppliers

Suppliers of adhesives, stainless-steel structural parts, and industrial PLCs face heightened specification alignment requirements. For instance, adhesive formulations must now include documented humidity resilience test data under ISO 9001–aligned protocols; stainless-steel grades must comply with ASTM A240/A276 minimum salt-spray endurance thresholds (e.g., ≥500 h per ASTM B117).

Contract packaging and OEM service providers

Service providers integrating or commissioning packaging lines in Indonesia will need updated technical documentation—including THAC-compliant validation reports—for client handover. Absence of certified components may trigger rework, extended commissioning cycles, or contractual liability exposure.

Logistics and compliance support firms

Freight forwarders and regulatory consultants must now incorporate THAC verification into pre-shipment audits. Since only BSN-authorized bodies (currently excluding all Chinese entities) can issue valid certificates, lead times for conformity assessment are expected to lengthen—particularly for first-time applicants requiring full-system testing.

Key Compliance Priorities for Exporters

Validate adhesive performance under tropical humidity conditions

Heat-seal adhesives must retain ≥95% bond strength after 72-hour exposure at 85% RH and 40°C (per THAC Annex A). Suppliers should prepare accelerated aging reports aligned with ISO 11607–2 methodology.

Upgrade PLC firmware with thermal drift compensation

Control systems must demonstrate real-time temperature compensation across ambient ranges of 25–45°C, verified via calibrated thermal chamber testing. Firmware version logs and algorithm documentation will be subject to audit during THAC assessment.

Confirm stainless-steel corrosion resistance grade

All load-bearing and process-critical stainless-steel components must be certified to at least AISI 316L or equivalent EN 1.4404, with salt-spray test reports (ASTM B117, 500 h minimum) issued by an SGS-BSN–accredited lab.

Secure THAC certification through authorized channels early

Given the absence of authorized Chinese certifiers, exporters should engage SGS or other BSN-designated bodies immediately to initiate pre-assessment, avoid Q3 2026 supply chain disruption, and align with upcoming public procurement specifications referencing THAC.

Emerging Technical Barrier in ASEAN Market Access

Analysis shows this is not merely a procedural update but signals a broader regional shift toward climate-adapted industrial standards. From an industry perspective, THAC reflects Indonesia’s move to reduce post-importation equipment failures in high-humidity operational environments—thereby lowering total cost of ownership for local converters. What deserves closer attention is the precedent it sets: similar environment-specific certifications could emerge in Thailand, Vietnam, or the Philippines as ASEAN harmonizes technical infrastructure requirements. Observably, the 6–9 month gap between announcement and enforcement suggests limited grace period for retrofitting or requalification—making proactive design integration essential.

A Strategic Inflection Point for Global Equipment Exporters

This THAC mandate marks a decisive step toward condition-specific regulatory gatekeeping in tropical markets. It underscores that environmental resilience—not just functional capability—is now a non-negotiable dimension of industrial equipment compliance. For exporters, success hinges less on generic CE or ISO certifications and more on demonstrable adaptation to localized operating conditions. A measured, technically grounded response—not rushed compliance—is the most appropriate path forward.
