About us
An engineering company that also supplies the parts
Hoan Tran Technical Automation Limited Company — HOANTRANTDH — was founded by automation engineers in Hai Phong, Vietnam. We program PLCs and SCADA, build panels, specify instruments, and supply the components we recommend. That combination is what our customers value: the person who quotes the part is the person who could commission it.

How we work
Engineering first
We lead with technical expertise — selecting the right product for the application rather than the product that is easiest to sell. If a cheaper variant or a competitor's part does the job better, we say so.
Honest supply
Genuine products from the manufacturer or authorized channels. Where a discontinued part must come from elsewhere, you are told, and the origin is documented. See our quality and documentation page.
Long-term relationships
We measure success by plants that keep running and customers who come back for the next line, not by single transactions. Spares planning and obsolescence monitoring are part of the service.
Vietnam base, international reach
Hai Phong is Vietnam's largest northern port and the centre of a fast-growing manufacturing region. From here we deliver locally within a day and export worldwide with full documentation.
