This comprehensive guide is designed for factory owners, procurement managers, and industrial importers planning to bring air compression equipment into Vietnam under the new Circular 30/2025 regulatory framework. Whether you operate in semiconductor manufacturing, digital technology production, or general industrial manufacturing in regions like Binh Duong, Dong Nai, or Hai Phong, you will learn exactly what the new 85% capacity and 115% energy consumption thresholds mean for your equipment choices, why used screw compressors rarely pass these benchmarks, and how Permanent Magnet Variable Frequency (PMV) technology from AirSpace Machinery Co., Ltd. provides a fully compliant, cost-effective alternative that slashes energy costs by 35-50%.
Can you still import used compressors into Vietnam in 2026? Yes, but only if they meet the strict new thresholds of Circular 30/2025/TT-BKHCN, which requires used machinery to maintain ≥85% of its original capacity and ≤115% of its original energy consumption design. For most factory owners, the cost of third-party verification and the risk of customs rejection make new Permanent Magnet Variable Frequency (PMV) screw air compressors the main viable high-ROI alternative for 2026 and beyond.
Starting January 1, 2026, the landscape for industrial imports in Vietnam changes permanently. Circular 30/2025 isn’t just another layer of red tape; it’s a fundamental shift toward green manufacturing and energy efficiency. If you’re betting on “cheap” second-hand hardware from overseas, you might find your investment stuck at the Hai Phong or Cat Lai port, racking up storage fees while failing to meet the Ministry of Science and Technology’s new efficiency benchmarks.
At AirSpace Machinery Co., Ltd., we’ve spent 20 years perfecting high-performance industrial air compression systems. With a 4,000 m² facility and 100M yuan in annual sales, we’ve seen how regulations like these can catch importers off guard. Here is everything you need to know about navigating Vietnam’s Circular 30/2025 and why PMV technology is your best move.
What Are the Key Requirements of Vietnam Circular 30/2025 for Used Machinery Imports?
Circular 30/2025/TT-BKHCN mandates that all used equipment, machinery, and production lines imported into Vietnam must have a remaining operational capacity of at least 85% compared to the original design and an energy consumption level not exceeding 115% of the original specifications.
This regulation specifically targets the semiconductor, digital technology, and general manufacturing sectors. For air compressors: the lungs of any factory: this creates a massive technical hurdle. A standard screw compressor that has been running for 5–7 years in a high-humidity environment rarely maintains 85% of its original flow rate (m³/min) without a total overhaul. Furthermore, as internal components wear, energy consumption inevitably spikes.
Under the new rules, you cannot simply “guess” these numbers. You need documented proof, often from certified inspection bodies, which adds thousands of dollars to the “cheap” price tag of used gear.
According to the International Energy Agency (IEA), compressed air systems account for approximately 10% of total industrial electricity consumption globally, and aging or poorly maintained compressors can waste up to 30% more energy than their rated specifications—making Vietnam’s 115% energy threshold a significant barrier for most used equipment.
Why the “85% Capacity Rule” Is a Compliance Barrier for Second-Hand Screw Compressors
The 85% capacity rule is difficult for used screw compressors to meet because air end wear, seal degradation, and cooling system scaling naturally reduce volumetric efficiency over time.
In a screw compressor, the “air end” is the heart of the machine. Even with meticulous maintenance, the tight tolerances required to maintain high pressure (bar/psi) and flow (m³/min) degrade. If a used 50HP compressor was designed to deliver 6.2 m³/min but now only delivers 5.0 m³/min due to internal leakage, it sits at 80% capacity: meaning it is legally barred from entering Vietnam under Circular 30/2025.
When you buy a new unit, such as our 50HP 37kW Variable Frequency Screw Air Compressor, you receive a factory-certified performance target. You aren’t just buying air; you’re buying a compliance insurance policy.
How Does the 115% Energy Consumption Limit Affect Your Import ROI?
The 115% energy consumption limit forces importers to prove that a used machine is not an “energy hog,” a task that is technically difficult without laboratory-grade flow meters and power analyzers.
Older, fixed-speed compressors are notoriously inefficient, often consuming 100% of their rated power even when the factory only needs 50% of the air. As these machines age, friction increases and cooling efficiency drops, pushing energy consumption well beyond the 115% threshold.
In contrast, Permanent Magnet Variable Frequency (PMV) technology allows the motor speed to adjust in real-time to meet demand. This doesn’t just meet the “115% rule”: it crushes it. Our PMV units typically operate at 30-50% higher efficiency than the aging units being imported as “used.”

| Maintenance | Immediate overhaul often required | 2-year warranty on core components |
| Import Risk | Possible rejection/seizure at port | Smooth customs clearance |
Southeast Asia Humidity: The Hidden Efficiency Killer for Imported Compressors
In Vietnam’s high-humidity climate, standard used compressors suffer from rapid oil emulsification and heat exchanger scaling, which quickly drops their efficiency below the 85% capacity threshold required by Circular 30/2025.
If you are operating in Binh Duong, Dong Nai, or Hai Phong, you know the humidity is brutal. Used machines imported from cooler climates (like Japan or Europe) often struggle when relocated to SEA. Their cooling systems aren’t sized for 35°C+ ambient temperatures with 90% humidity. This causes the machine to run hot, thinning the lubricant and reducing the seal between the screws.
Our 20HP 15kw Variable Frequency Screw Air Compressor is engineered for these extreme climates. We use oversized coolers and high-efficiency moisture separators to ensure the air stays dry and the machine stays cool, maintaining that 100% design capacity for years, not months.
How to Verify CE and ISO 9001 Documentation for Vietnam Customs Clearance
To ensure a smooth import process under Vietnam’s evolving regulations, buyers must verify that their supplier provides legitimate CE and ISO 9001:2015 certifications that match the physical nameplate of the compressor.
Customs officials in Vietnam are becoming increasingly tech-savvy. They don’t just look at the machine; they look at the paperwork. AirSpace Machinery provides full documentation suites for every export. We ensure that the technical specifications: specifically the flow rate and power consumption: are clearly stated and verifiable.
If you’re looking for a specialized setup, like an All-in-One Laser Cutting Screw Compressor, having the right certifications is the difference between starting production on Monday or spending a month in a legal battle with the Ministry.
Why PMV Technology Is a “No-Brainer” for Vietnam Factory Compliance in 2026
Permanent Magnet Variable Frequency (PMV) technology is the most effective way to target compliance with Vietnam’s energy-saving mandates because it eliminates unload power consumption and maintains peak efficiency across the entire operational range.
Look, the days of “cheap” used gear are over. Circular 30/2025 is a clear signal: Vietnam wants a modern, efficient industrial base. Betting on a used machine is betting that a 10-year-old compressor still performs like new. It’s a bad bet.
By switching to a new PMV unit, you:
- Avoid the 85% capacity trap: You get 100% of the air you pay for.
- Slash energy bills: Most of our clients see a return on investment within 12–18 months just through electricity savings.
- Future-proof your factory: You won’t have to worry when the next circular (Circular 2028? 2030?) comes out with even stricter rules.

Frequently Asked Questions (FAQ)
1. Does Circular 30/2025 apply to all air compressors?
Yes, if they are imported as part of a used production line or as standalone used equipment for the sectors defined (semiconductor, digital tech, and general manufacturing lines).
2. How is the “85% capacity” actually measured?
Usually through a Free Air Delivery (FAD) test according to ISO 1217 standards. For used machines, this must be performed by a recognized inspection agency before or during the import process.
3. Is it possible to “refurbish” a used compressor to meet the 115% energy rule?
It is possible but rarely cost-effective. You would need to replace the air end and potentially the motor, at which point the cost of refurbishment plus shipping and inspection often exceeds the price of a new, high-efficiency AirSpace PMV unit.
4. What is the lead time for a new AirSpace compressor to Vietnam?
Lead times are neutral and depend entirely on your specific configuration (e.g., pressure requirements, voltage, and tank size). Contact us for a specific quote.
