Three Signals Pointing to the Same Conclusion
Judging whether an industry has entered a “concentrated replacement cycle” typically requires three indicators: whether regulatory deadlines are clear, whether enforcement pressure is sustained, and whether new capacity is subject to upfront requirements. For VOCs treatment in film coating, all three signals are lit simultaneously.
Signal One: IED 2.0 Transposition Deadline in the Second Half of 2026
The revised Industrial Emissions Directive (IED 2.0) entered into force on 4 August 2024. Member States must transpose it into national law within 22 months—by 1 July 2026.
Annex VII of the IED explicitly includes “film coating” within its scope, with a solvent consumption threshold of 5 tonnes per year. For installations exceeding 15 tonnes/year, waste gas emission limits are 50 mg C/Nm³ (drying) or 75 mg C/Nm³ (coating), and the fugitive emission limit is 20% of solvent input.
This means: from 1 July 2026, European authorities will permit and regulate film coating installations under the transposed national law. For existing installations, the BAT-associated limit compliance countdown is typically 4 years after BAT conclusions are published. For the surface treatment BAT conclusions applicable to film coating (2020/2009), the compliance deadline has already entered its final phase.
Signal Two: Post-14th Five-Year Plan, Enforcement on Coating Industry Remains Strong
During China’s 14th Five-Year Plan period, VOCs were included in total emission control for major pollutants. The 2023 “Action Plan for Continuous Improvement of Air Quality” issued by the State Council further clarified VOCs reduction targets and work measures.
From the standards perspective, GB 37822-2019 requires: when the NMHC initial emission rate in collected waste gas is ≥3 kg/h, VOCs treatment facilities must be installed with treatment efficiency not less than 80%; in key regions, the threshold drops to 2 kg/h.
The conclusion of the 14th Five-Year Plan does not mean enforcement relaxation. On the contrary, as air quality improvement targets continue to advance, the coating industry—as a key VOCs emission sector—will only see increased frequency and intensity of enforcement inspections.
Signal Three: New Capacity in Southeast Asia and the Middle East Required to Pre-Install RTO
Southeast Asia is undergoing a regulatory upgrade. Vietnam’s QCVN 19:2024 took effect on 1 July 2025, with existing facilities required to meet first-tier limits and new projects required to meet stricter second-tier limits from start-up. Thailand’s Ministry of Industry issued VOC emission control requirements targeting the chemical and petrochemical sectors. As of Q1 2026, seven of ten ASEAN countries have promulgated mandatory VOCs emission limit standards.
The region exhibits a typical “standards-first, infrastructure-later” pattern. This means that for new film coating capacity, RTO is no longer an “optional item” but an upfront condition that must be incorporated at the design stage.
The Nature of the Window: Not for Procrastination, but for Advance Preparation
The three signals above collectively point to one judgment: VOCs treatment in the film coating industry is at the starting point of a concentrated replacement cycle.
The nature of this window needs to be accurately understood.
It is not a window of “regulatory suspension.” The legal force of IED 2.0 already exists; transposition is only a matter of time. China‘s VOCs regulatory framework is already established; enforcement will only strengthen. Southeast Asia’s limit standards are already in force; enforcement capacity is being built.
It is a window where “proactive upgrading costs less.” For existing factories, proactive upgrading before the compliance deadline allows installation and commissioning during low-production seasons, avoiding shutdown losses from reactive rectification. For new factories, incorporating RTO at the original design stage allows integrated planning of foundations, ducting, and electrical capacity, avoiding duplicate investment in later retrofits.
The RTO equipment cycle from design to installation and commissioning is approximately 5 to 6 months. If action is delayed until the compliance deadline approaches, this cycle may become a bottleneck—limited supplier capacity, tight installation resources, compressed commissioning time.
Assessing the Length of the Window
Based on currently available regulatory information, the window for proactive upgrading is approximately 2 years.
The basis for this judgment:
The IED 2.0 transposition deadline is 1 July 2026. After transposition, BAT-associated limit compliance obligations will formally take effect for existing installations. From transposition completion to comprehensive enforcement coverage, there is typically a 1-2 year transition period. This means the “proactive window” for European film coating factories closes around 2028.
For China, the enforcement rhythm of VOCs treatment is tied to air quality improvement assessment cycles. For the coating industry, factories with substandard or improperly operated treatment facilities are becoming key targets of environmental inspections.
For Southeast Asia, Vietnam and Thailand‘s standards are already in force, with new projects required to comply from start-up. Retrofit pressure on existing facilities will concentrate in 2026-2027.
Implications for Decision-Makers
If the factory is located in the EU or exports to the EU: Assess now whether existing treatment infrastructure can meet IED Annex VII emission limits and BAT-associated limits. If not, begin evaluating alternatives. The 5-6 month RTO delivery cycle means the decision should be made by the end of 2026 at the latest.
If the factory is located in China: Monitor VOCs emission standards and enforcement developments in your province. For factories with multiple coating lines, the zeolite rotor + RTO combination can control operating costs while meeting treatment efficiency requirements.
If planning new film coating capacity in Southeast Asia or the Middle East: Incorporate RTO into planning at the site selection and design stage. The region’s “standards-first, infrastructure-later” pattern means new projects will face stricter compliance requirements than existing facilities. The cost of pre-installing RTO is far lower than the cost of later retrofits plus compliance risk.
A Judgment Boundary to Note
The window judgment is based on currently available public information. There is uncertainty in IED 2.0 transposition progress—the European Commission has simultaneously tabled an “Environmental Omnibus” that may modify the provisions Member States are required to transpose. This means the transposition timeline may be further delayed.
But delayed transposition does not change the direction of the trend. The direction of regulatory tightening is clear. For factory decision-makers, the critical judgment is not “when enforcement begins,” but “when preparation should start.”
