The evaporative air cooler import procedure is a category of water-evaporation cooling equipment with an HS code classification process far more complex than the product’s simple appearance suggests, since identical equipment of different weights falls under two different HS headings with different management policies. This is also a point of confusion for many businesses between evaporative air coolers and air conditioners — two types of equipment with entirely different operating principles and legal obligations.
Not every business fully understands the evaporative air cooler import procedure, especially HS code classification by equipment weight (above or below 20kg) and correctly determining the specialized quality inspection obligation. An error in HS code determination, or confusion with regulations meant for air conditioners, can result in unnecessary inspection costs or clearance delays.
In this article, 3W Logistics presents the complete evaporative air cooler import procedure under the latest legal regulations and tariff schedule — from legal conditions, HS codes, tax calculation, and required documentation, through the step-by-step process and practical risks, from the perspective of a forwarder experienced in handling imported cooling equipment.
1. Legal conditions for importing evaporative air coolers
Water-evaporation air coolers are not on the list of prohibited import goods and do not require an import license, but the key point in the evaporative air cooler import procedure is clearly distinguishing them from air conditioners, to avoid mistakenly applying regulations meant only for refrigerant-compressor equipment.
| Condition | Detailed Content |
|---|---|
| Distinction from air conditioners | Evaporative air coolers operate on the principle of water evaporation, without a refrigerant compressor or cooling gas as with air conditioners, so they are not subject to Minimum Energy Performance Standard (MEPS) testing or the mandatory energy labeling that applies to air conditioners |
| Specialized quality inspection | Depending on HS code classification by weight, certain models may be subject to post-clearance quality inspection regarding electrical safety, performance, and non-toxic materials; businesses should contact a certification body to confirm the specifics for each model before importing |
| Case of classification as a household electric fan | If the model has a rated voltage not exceeding 250V (single-phase) or 480V (other) and motor power not exceeding 125W, it may be classified as a household electric fan subject to quality inspection under Ministry of Science and Technology regulations |
| Product labeling | A Vietnamese supplementary label under Decree 43/2017/ND-CP: product name, model, wattage, origin, importer, affixed in a clear, easily visible position |
Practical note: Because the name includes the word “cooler,” many businesses default to applying the full set of regulations meant for air conditioners (MEPS testing, mandatory energy labeling) to evaporative air coolers — this is a common misunderstanding in the evaporative air cooler import procedure. In fact, the two types of equipment operate on entirely different principles: air conditioners use a compressor and refrigerant gas, while evaporative air coolers simply use a fan blowing air through a water-soaked cooling pad to lower temperature via evaporation. That said, businesses still need to clearly determine the quality inspection obligation depending on the HS code and specific technical specifications of each model, since current guidance sources are not entirely consistent — checking directly with a certification body before signing the contract is a necessary step.
2. HS code and import tax for evaporative air coolers
Water-evaporation air coolers are a fairly unique product when it comes to HS code classification — the same operating principle, but different weight, places the product in two different HS headings in the Import-Export Tariff Schedule.
| Heading/HS Code | Detailed Description | Import Tax (MFN) |
|---|---|---|
| 84.79 — Machines and mechanical appliances having individual functions, not elsewhere specified (applies to equipment weighing over 20kg) | ||
| 8479.60.00 | Evaporative air coolers, weight over 20kg — used for warehouses and large spaces | 0–10% |
| 85.09 — Electromechanical domestic appliances with self-contained electric motor, other than vacuum cleaners of heading 85.08 (applies to equipment weighing under 20kg) | ||
| 8509.80.90 | Evaporative air coolers (household water fans), weight under 20kg — the most common code when importing home and office air coolers | 10–20% |
| 85.09 — Parts and accessories | ||
| 8509.90.00 | Parts of air coolers under 20kg (water pump, cooling pad, motor) imported separately | 0–5% |
Important note on HS codes and tax: Correctly classifying under heading 84.79 or 85.09 depends entirely on the equipment’s actual weight (the 20kg threshold), not on wattage or external size — a point many businesses easily get confused about when declaring. For goods with a valid Certificate of Origin (C/O) from countries with an FTA with Vietnam, import tax can be reduced to 0% from the standard MFN rate. Regarding VAT, the current rate of 8% applies through December 31, 2026 under Decree 174/2025/ND-CP; after that date, businesses should check for updated policy, as the rate may revert to the standard 10%. In the evaporative air cooler import procedure, weighing the actual weight of each model before declaration is an unskippable step to avoid misapplying the HS code.
3. Documentation for the evaporative air cooler import procedure
The documentation set for the evaporative air cooler import procedure is relatively light, per Circular 38/2015/TT-BTC (as amended by Circular 39/2018/TT-BTC).
| Document | When to Prepare | Important Note |
|---|---|---|
| Sales Contract | Before deposit | Clearly state model, weight, wattage, and terms for providing the C/O |
| Commercial Invoice & Packing List | Before goods are shipped | Clearly state the net weight of each unit to serve as the basis for determining the HS code under heading 84.79 or 85.09 |
| Bill of Lading | After goods are loaded onto the vessel | Air coolers are typically shipped in dry containers, packed in cartons or on pallets depending on size |
| Catalogue/technical documentation | Before declaring the HS code | Serves as the basis for determining weight, wattage, and voltage to apply the correct HS code and determine quality inspection status if applicable |
| Conformity Certificate (if mandatory) | Before or after clearance, depending on the applicable regulation | Issued by a competent inspection body; confirm in advance with the certification body whether the specific model is mandatory |
| C/O (Certificate of Origin) | Before goods are shipped | Needed to benefit from preferential FTA import tax instead of the standard MFN rate |
| Electronic customs declaration (VNACCS/VCIS) | Once documentation is complete | Declare the correct HS code under heading 84.79 or 85.09 depending on the actual weight |
4. Step-by-step evaporative air cooler import procedure
Step 1: Check weight, technical specifications, and determine the HS code
Determine the equipment’s actual net weight (above or below 20kg), wattage, and voltage, and work with the supplier to obtain a detailed catalogue, from which the correct HS code under heading 84.79 or 85.09 can be determined.
Step 2: Confirm quality inspection status with a certification body
Contact a certification body or specialized management authority to confirm whether the intended model is subject to quality inspection or conformity declaration, avoiding confusion with regulations meant for air conditioners.
Step 3: Negotiate the contract and require a C/O
Sign the air cooler purchase contract, clearly stating weight, wattage, and model, and include a C/O requirement in the contract terms to benefit from preferential import tax.
Step 4: Transport goods to a Vietnamese port
Air coolers are typically shipped in standard dry containers; sturdy carton packaging or pallet stacking is required, with the internal cooling pad and water pump secured to prevent damage during long-distance transport.
Step 5: Customs declaration and clearance
File the VNACCS/VCIS declaration with the full HS code and related documentation. For models not subject to quality inspection, clearance proceeds quickly once import tax and VAT have been paid in full; for models subject to inspection, wait for results or undergo post-clearance inspection depending on the applicable regulation.
Step 6: Receive goods, apply labeling, and release for circulation
After clearance, complete the required Vietnamese supplementary labeling, receive the goods, and transport them to the warehouse. Keep complete documentation on file to support post-clearance inspection if requested by competent authorities.
5. How to calculate import tax on evaporative air coolers
Evaporative air coolers are not subject to special consumption tax, only import tax and VAT. As an example, for a shipment of household air coolers under 20kg imported from China (HS code 8509.80.90) with a CIF price of VND 300 million, comparing the case with and without a C/O:
| Tax / Cost Item | Without C/O (ordinary rate 20%) | With C/O ACFTA / MFN (0%) |
|---|---|---|
| CIF price | VND 300,000,000 | VND 300,000,000 |
| Import tax | 20% × 300M = VND 60,000,000 | 0% × 300M = VND 0 |
| VAT (8%, applicable through end of 2026) | 8% × (300+60)M = VND 28,800,000 | 8% × (300+0)M = VND 24,000,000 |
| Total tax payable | VND 88,800,000 (~88.8 million) | VND 24,000,000 (~24 million) |
| Savings with C/O/MFN | ~VND 64,800,000 — businesses should negotiate for the supplier to assist with obtaining the C/O right at the contract signing stage to optimize tax cost. | |
From 3W Logistics’ practical experience: With evaporative air coolers, the most common mistake we see in the evaporative air cooler import procedure is businesses declaring based only on the manufacturer’s published specifications without weighing the equipment’s actual net weight — while actual weight sometimes deviates from the catalogue due to version differences or included accessories. Since the 20kg threshold determines whether the equipment falls under heading 84.79 or 85.09, with different management policies, confirming the accurate weight and consulting a certification body before signing the contract helps businesses avoid misapplying the HS code and incurring unplanned inspection costs. — Ms. Apple, CCO, 3W Logistics
6. Common risks in the evaporative air cooler import procedure
| Risk | Manifestation | Prevention |
|---|---|---|
| Confusion with regulations meant for air conditioners | Mistakenly applying the MEPS testing and mandatory energy labeling requirements for air conditioners to an evaporative air cooler | Clearly state the operating principle (water evaporation, no cooling gas) in the contract and catalogue to distinguish clearly from air conditioners |
| Misapplying the HS code by weight | Mistakenly declaring HS heading 84.79 (over 20kg) for equipment actually under 20kg, or vice versa — customs reclassifies the goods and retroactively collects the tax difference under Decree 128/2020/ND-CP | Weigh the equipment’s actual net weight before declaration, not relying solely on catalogue specifications |
| Overlooking the quality inspection obligation if applicable | A model with specifications matching the household electric fan category subject to quality inspection, but the business did not check in advance | Contact a certification body for confirmation before signing the contract, especially for models with small motor power and common voltage |
| Damage to the water pump or cooling pad during transport | The internal water pump or corrugated cooling pad is damaged by impact or dampness during long-distance transport | Require the supplier to use shock-resistant, moisture-resistant packaging to standard, and purchase adequate cargo insurance |
| Product label missing mandatory information | Missing wattage, voltage, or origin details on the Vietnamese supplementary label — customs holds the goods and requires supplementary labeling at port | Prepare a complete supplementary label sample under Decree 43/2017/ND-CP before the goods arrive at port |
