Every ISO 9001, IATF 16949 or AS9100 audit in Vietnam ends at the same question: where were these instruments calibrated, and is that laboratory accredited for that measurement? This guide lists the calibration providers that FDI factories in Ho Chi Minh City, Bình Dương and Đồng Nai actually use, what each one is known for, and how to check an accreditation claim in ten minutes. Lost in HCM does not operate a calibration laboratory; we rent and sell test equipment and we help foreign companies find the right local partners, which is why we wrote this.
How accreditation works in Vietnam
Vietnamese laboratories are accredited to ISO/IEC 17025 by the Bureau of Accreditation (BoA, Ministry of Science and Technology) under the VILAS scheme. Each accredited laboratory has a VILAS number and a published scope schedule listing exactly which quantities, ranges and uncertainties are covered. Some laboratories in Vietnam hold accreditation from foreign bodies (for example ANAB or A2LA) instead of or in addition to VILAS; auditors accept both when the body is an ILAC MRA signatory. The scope schedule, not the logo, is what your auditor reads. Check it at boa.gov.vn.
The providers
- QUATEST 3 (Quality Assurance and Testing Center 3)The state metrology centre for the south and the default choice for legal metrology and audits. Accredited under VILAS 036; the published scope covers electrical and electronic instruments, length and dimensional, mass and force, hardness, pressure, volume and flow, temperature and physicochemical measurements. Head office at 49 Pasteur, District 1, with calibration facilities in Cát Lái (Thủ Đức) and Biên Hòa 1 industrial zone, Đồng Nai, and on-site calibration for larger plants. Strengths: breadth of scope, government recognition, on-site work near the industrial parks. Watch-outs: lead times during audit season, so book early. Website: quatest3.com.vn.
- Vietnam Metrology Institute (VMI), southern facilityThe national metrology institute maintains the primary standards for Vietnam and operates a southern facility for high-accuracy work such as reference standards and precision electrical and dimensional artefacts. Use it when you need the lowest uncertainty or a reference standard calibrated, not for routine multimeters. Confirm the current address of the facility and the certificate issuer before sending instruments. Website: vmi.gov.vn.
- Manufacturer (OEM) calibration: Keysight, Fluke, TektronixFor RF and high-end instruments (spectrum and network analyzers, signal generators, oscilloscopes above about 1 GHz) an OEM calibration is often the only way to get full-specification coverage with manufacturer adjustments. Keysight, Fluke Calibration and Tektronix/Keithley all take Vietnamese customers through their local sales channels; the instrument usually travels to a regional service centre in Malaysia, Singapore or Japan, so plan four to eight weeks door to door and ask which accredited laboratory will issue the certificate. Tektronix service also covers Keithley and Fluke instruments.
- International inspection groups: SGS, TÜV SÜD, Bureau Veritas, Intertek, VinacontrolAll five have offices in Ho Chi Minh City and serve the industrial provinces. Their Vietnamese calibration scopes vary by branch and year, and some work is subcontracted or performed at a regional laboratory. They are convenient when you already use them for inspection, product testing or certification, but treat calibration accreditation as something to verify per quotation: ask which laboratory issues the certificate and whether the measurand is on its scope.
- Private Vietnamese calibration laboratoriesDozens of private laboratories in Ho Chi Minh City, Bình Dương and Đồng Nai calibrate multimeters, pressure gauges, thermometers, torque wrenches, scales and gauges at lower prices and with faster turnaround than the state centres, and several hold VILAS accreditation. Because many trade under generic names (hiệu chuẩn, Cal-Lab, calibration services), identify the legal entity, look it up on the BoA register, and ask for the scope schedule before you decide. A good private lab will send the certificate and the scope PDF the same day you ask.
Which provider for which instrument
| Instrument | Typical route | Notes |
|---|---|---|
| Digital multimeters, clamp meters, process calibrators | QUATEST 3 or a VILAS private lab | Ask for uncertainty at your working ranges |
| Oscilloscopes to 500 MHz, power supplies, electronic loads | QUATEST 3 or VILAS private lab; OEM for adjustment | Check bandwidth and timebase are in scope |
| Spectrum, signal and network analyzers, RF generators | OEM (Keysight, R&S, Tektronix) | Regional service centre; 4 to 8 weeks |
| Torque wrenches, torque testers | QUATEST 3 or a torque-scope VILAS lab | ISO 6789 class and direction (CW/CCW) on the certificate |
| Pressure gauges, transmitters, temperature sensors, thermal cameras | QUATEST 3, VMI, VILAS private labs | On-site calibration available for plant instruments |
| Dimensional: calipers, micrometers, gauge blocks, CMM artefacts | QUATEST 3, VMI | Temperature-controlled lab required |
Five things to ask for before you send anything
- The current accreditation certificate of the laboratory (VILAS or foreign body) and its expiry date.
- The scope schedule showing your measurand, range and uncertainty, not only the ISO/IEC 17025 logo.
- Confirmation that the certificate is issued by the accredited laboratory itself, not a reseller or an unaccredited branch.
- The traceability statement, environmental conditions and whether adjustment and repair are included or quoted separately.
- Turnaround, on-site option and a loaner plan so the line does not stop while the instrument is away.
Keep measuring while your instrument is away
Calibration means downtime unless you have a spare. Lost in HCM rents calibrated test equipment by the week or month from local stock, delivered next day across Ho Chi Minh City, Bình Dương and Đồng Nai, and every rental unit ships with a valid calibration certificate. If you are setting up a new plant, the factory setup checklist shows which instruments need accredited calibration and which need only a traceability statement.
FAQ
Do I need VILAS or is a foreign accreditation acceptable?
Both are accepted by ISO 9001, IATF 16949 and AS9100 auditors in Vietnam when the accreditation body is an ILAC MRA signatory. Customs and legal-metrology requirements can specify Vietnamese verification; for legal instruments (scales, fuel meters) use QUATEST 3.
How long does calibration take in Ho Chi Minh City?
Routine electrical and mechanical instruments: three to ten working days at QUATEST 3 or a private laboratory; on-site visits can be arranged for larger batches. OEM calibration abroad: four to eight weeks.
How much does it cost?
As a guide, a handheld multimeter or pressure gauge costs a few hundred thousand to about two million VND; an oscilloscope one to four million VND; RF analyzers at an OEM centre from a few hundred to over a thousand USD. Every laboratory quotes per instrument and scope.
Does Lost in HCM calibrate instruments?
No. We rent and sell test equipment and help FDI companies with housing, POSM, events and market analysis. We wrote this guide because our customers ask us which laboratory to use, and we can lend you an instrument while yours is away.
Keep the line running while you decide
Lost in HCM rents calibrated test equipment from local stock with next-day delivery across Ho Chi Minh City, Bình Dương and Đồng Nai, sells tools and new instruments, and covers the rest of a landing: housing, POSM printing, exhibitions and market analysis.
