Thailand Production Base
For brands managing tariff exposure, HisoAir offers validated platforms built in either China or Thailand. This Thailand facility gives you a second country of origin on the same engineering, the same tooling and the same quality protocol — with origin substantiated in writing before each shipment rather than assumed.
Why This Facility
Samut Prakan sits inside an established industrial zone 40 minutes from Bangkok's airport and within reach of Laem Chabang port. But location is not the reason this site exists — optionality is.
A Second Origin on the Same Platform
Tooling for platforms produced here is transferred from our China operation, so you are not requalifying a new design. Same mould, same engineering, same quality protocol — a different country on the customs declaration.
Origin Substantiated, Not Assumed
Shipping from Thailand does not by itself make a product Thai-origin. For each program we document bill-of-materials localization and the substantial transformation basis, and issue written origin confirmation before shipment.
Progressive Localization
Injection moulding and filter media are sourced in Thailand today. Packaging, power cords and metal parts are in active qualification. We publish the current localization position per program rather than a blanket claim.
Unified Quality Across Both Origins
Performance validation for all platforms runs through the group's China laboratory, so a Thailand-built unit is verified against the same CADR, acoustic and safety criteria as its China-built equivalent.
Core Capabilities
This site is in production ramp-up. We describe what is operational now and what is in qualification, because a tariff strategy built on an overstated capability fails at the border, not in the meeting.
Injection Moulding — Localized
Production tooling transferred from China operations and running on site, establishing local manufacture of structural components.
Final Assembly
Assembly lines operating with in-line functional test stations, running against the same work instructions as China production.
Filter Media — Locally Sourced
Thai filter suppliers qualified and in supply, localizing a core consumable within the country of manufacture.
Quality Inspection & Functional Testing
IQC, in-process and final inspection performed on site under ISO 9001, with functional and safety testing conducted locally.
Performance Validation — Group Laboratory
CADR, acoustic and reliability validation executed at the group's China laboratory, ensuring one verification standard across both production origins.
Supply Chain Localization Programme
Ongoing qualification of Thai packaging, power cord and metal part suppliers, with localization status reported per program.
Products & Manufacturing Support
Platforms available with Thailand as country of origin. Category availability is confirmed per program alongside the origin assessment.
Purificazione dell'aria
HEPA, activated carbon, UV-C and ionization architectures across desktop, floor-standing and combination platforms, with CADR validated in-house from 77 m³/h through 476 m³/h-class performance.
Umidificazione
Ultrasonic, evaporative, warm-mist and hybrid platforms, including large-tank formats with integrated humidistat control and pump-driven mist delivery.
Dehumidification
Compressor-based residential and basement dehumidification platforms, including combination units pairing moisture removal with particulate filtration.
Air Movement & Circulation
BLDC pedestal, tower and rechargeable portable fan platforms with app control, plus purifier-fan combination architectures.
Quality, Origin Verification & E-E-A-T
For dual-origin programs, quality governance and origin governance are the same discipline. Both are documented per program and available for audit.
Standard Quality Control Process
Shipment from Thailand does not by itself establish Thai country of origin. Origin is determined per product under the rules of the destination market, based on the bill of materials and the degree of transformation performed at this site, and is confirmed in writing for each program before shipment. Tariff treatment varies by destination market, product classification and prevailing trade measures; HisoAir does not provide customs or legal advice and recommends customers confirm classification and duty treatment with their own broker or counsel. Product certifications and test reports are model-specific and may vary by manufacturing location and destination market. Certifications held by partner manufacturing entities are issued to that entity and to specific models and do not transfer automatically between facilities.
Site Progress & Verification
This site is in production ramp-up. Rather than present a mature operation, we publish verified commissioning milestones and update them as the site scales.
