Quick answer
Thailand, Vietnam and Malaysia manufacture HVAC ducting, grilles, louvers, dampers, washable filters, filter frames and selected replacement filter products for commercial contractors, distributors and OEM service channels. Typical MOQ is 500-2,000 pieces for metal assemblies or 1,000-5,000 filter units, with FOB USD 2.50-45.00 depending on size, material and filter grade. The main buying risks are dimensional tolerance, airflow performance, corrosion protection, fire rating and packaging damage on bulky items.
Country fit
| Country | Best for | MOQ | FOB reference |
|---|---|---|---|
| Thailand | Galvanized ducting, dampers, grilles, commercial metalwork | 500 pcs | USD 4.00-45.00 |
| Vietnam | Sheet metal HVAC parts, filter frames, louvers | 800 pcs | USD 2.50-32.00 |
| Malaysia | Filter media, washable filters, documented QA programs | 1,000 pcs | USD 3.20-28.00 |
| Indonesia | Simple grilles, brackets and low-complexity sheet metal | 1,500 pcs | USD 2.80-18.00 |
Specs to lock before quoting
- Material: galvanized steel, aluminium, stainless, powder coat, coating thickness and corrosion target.
- Dimensions: tolerance, flange pattern, hole positions, gasket and installation hardware.
- Performance: airflow, pressure drop, filter efficiency, sound level and leakage class where relevant.
- Fire and safety: flame spread rating, damper type, labeling and installation instructions.
- Packing: corner protection, nested stack rules, pallet height and humidity protection.
Compliance
- US: UL, ASHRAE or project-specific submittal requirements depending on application.
- EU/UK: CE-adjacent documentation for powered components, REACH and construction product requirements where applicable.
- Filters should use test methods and ratings that match the target market, not only local factory labels.
- Powder coat, insulation and gasket materials need supporting data for commercial building projects.
Quality control plan
- Approve drawings with tolerances and installation hole positions before sampling.
- Inspect sheet thickness, coating, welds, rivets and fit-up during fabrication.
- Run airflow or pressure-drop checks for filter and louver programs when specified.
- Pre-shipment inspection verifies dimensions, labeling, packaging strength and pallet loading plan.

FAQ
Can ASEAN factories supply HVAC parts for commercial construction?
Yes, especially metal ducting, grilles and filter frames, but submittal documents must match the project requirements.
What fails most often?
Small dimensional errors, weak packaging and unsupported filter-efficiency claims.
Can parts be consolidated with other building products?
Yes, but bulky HVAC products need carton engineering and load planning so cube does not erase the FOB advantage.
