Research and Development Center Setup in Thailand: BOI and Operating Approvals

Define the research project before selecting the BOI route

Start with the work product and the point at which research becomes a customer-facing service or commercial production. “R&D center” describes a business plan, not a single legal form or blanket incentive. In the BOI’s current Guide, general research and development appears as activity 10.2 in the professional-services group and is classified A1. A1 is the incentive category, while the activity code and project-specific conditions define the work that is promoted.

For activity 10.2, the Guide separates four kinds of work. Basic research investigates new knowledge without an initial application; applied research uses knowledge toward a new product or process; pilot development scales research into a prototype or semi-industrial process test; and demonstration development tests a process at industrial level to verify technology and commercial-scale viability. A practical classification question is whether the Thai team is creating and testing new knowledge or merely testing an existing product for a customer.

The BOI Guide separately lists Contract Research Organizations and Clinical Research Centers in the medical-industry section. For example, the Clinical Research Center activity has its own requirements for human-subject stages, researcher and facility details, Good Clinical Practice, and ethics review. A clinical study should therefore be classified against both the R&D project and the medical-sector activity before the application narrative is fixed. The 2026 Investment Promotion Guide is the controlling starting point for matching the proposed business to the eligible-activity conditions.

To keep the proposed activity testable, prepare a one-page project boundary covering the research question, inputs, method, expected prototype or result, customer services, planned scale, Thai and overseas collaborators, and the point at which manufacturing begins. That description helps keep the BOI project, the company’s stated activities, and each operational permission aligned.

Test activity 10.2 and its financial threshold

Activity 10.2 requires a substantive research plan and a project-specific resource basis . The applicant must describe the R&D scope and details such as the number of researchers, their academic profiles, and their work experience. It must also meet one of two thresholds. The salary route is for at least THB 1.5 million in annual salaries for R&D personnel as new employment; the alternative is at least THB 1 million in capital investment, excluding land, working capital, and vehicles.

These figures are BOI project conditions, not a general company registered-capital minimum. Do not add payroll and equipment casually to make an application appear to pass: ask which qualifying route the project will rely on and keep the supporting schedule traceable to the proposed activity. The Guide also classifies activity 10.2 as A1, which carries an eight-year corporate-income-tax exemption without a cap under the basic incentive table; actual use depends on the approved project, the certificate, and compliance with its conditions.

The salary route requires new R&D employment; an existing team alone does not satisfy that condition. If the project uses the capital route instead, keep the exclusions visible in the investment model. The BOI may request clarification of how equipment supports the research scope, so descriptions such as “laboratory setup” are not enough by themselves.

Do not confuse the activity’s basic incentive with merit-based incentives for R&D spending. The Guide describes a separate competitiveness-enhancement measure for investments or expenditure such as in-house R&D, domestic outsourced work, or collaboration with overseas institutions. Its R&D test includes spending equal to at least 1% of total sales in the first three years or THB 200 million, whichever is lower, and the same expenditure cannot be counted for duplicate incentives. Treat that as a separate model, not as a substitute for the 10.2 threshold.

Turn the research plan into a BOI evidence file

Translate the lab plan into evidence that a reviewer can test. A project narrative should explain not only what the facility will own, but what each team, machine, and budget item contributes to the claimed R&D activity. This crosswalk is useful before the e-Investment form is drafted because it reveals mismatches between research objectives and planned commercial services.

BOI’s general application checklist also lists business history and details, audited financial statements if available, photographs or catalogues, process documentation, main machinery details, and supporting materials for special conditions. A pure research project may not have a product catalogue; use a clear technical process diagram and equipment schedule instead of manufacturing evidence that does not exist. The BOI application document checklist should be checked against the current form and the activity-specific requirements.

Prepare the proof in a reviewable order: one-page project brief; activity classification; research work packages; personnel and threshold schedule; equipment and capital schedule; site and utility plan; expected outputs and IP chain; and a list of permissions that remain conditional. Add translations or certifications only where the responsible authority or filing route actually asks for them.

When the project belongs to an existing group, record who owns background IP, who owns new results, whether Thai researchers work for a Thai entity, and whether a parent or affiliate receives research services. Those facts can affect whether the Thai operation is conducting R&D, providing a service, or performing an internal group function. They also help prevent the application from mixing separate promoted activities into one undifferentiated “innovation center.”

Screen operating approvals from the workbench

There is no single “R&D operating license” that covers every laboratory. Start from the specific acts: install, possess, import, test, handle human or animal subjects, or sell a service. A low-impact desk research center may need a different approval path from a wet lab or a pilot process. The checks below are triggers for a regulator review, not a substitute for a technical classification.

The Factory Act definition is not triggered by the word “laboratory” alone. The 2019 amendment defines a factory using machinery of at least 50 horsepower or at least 50 workers, with the activity also falling within a prescribed factory type. The law also permits rules that exempt certain research-purpose factories from parts of the Act, but that is not a blanket exemption for every R&D room. Check the DIW Factory Act and amendment index and the current factory type and local rules before installing equipment.

For chemicals, screen each substance and action separately. Thailand’s hazardous-substance controls distinguish categories with different requirements, and the responsible agency depends on the listed substance. DIW publishes a Hazardous Substance single-window and service portal , including chemical-consultation and permit systems. A research-use exception may exist for specified controlled substances and conditions; do not assume that it covers all imports, quantities, or users.

Clinical research introduces another set of gates. The Thai FDA’s drug-research resources distinguish the approval requirements for research drugs and ethics review; its innovation office publishes supporting-document checklists for clinical research products. The Thai FDA drug research page and the relevant product-specific FDA manual should be checked before a sponsor imports or produces trial materials. The Thai Clinical Trials Registry encourages prospective registration before recruitment, but a registry entry is not a substitute for FDA permission or ethics approval.

Make the permit map activity-specific. One sheet can show each work package, substance or sample, site, responsible officer, application owner, required evidence, and the written proof that unlocks the next stage. If a permit is “not applicable,” record the reason and the person who confirmed the classification; do not leave the field blank.

Separate promotion, company registration, and operation

BOI, DBD, and operating regulators decide different questions. BOI decides whether the proposed project fits a promoted activity and its incentive conditions. DBD registers the Thai legal person and its corporate particulars. Sector and site regulators decide whether the facility, materials, product, study, or service may lawfully operate. A positive outcome from one track does not silently complete the others.

For an investor using a Thai limited company, check the foreign-ownership route and registered business scope in parallel with the BOI project description. A BOI certificate may support specific non-tax privileges and can provide a route to a Foreign Business Certificate for promoted activity, but the company must still be registered and the permitted operation must stay within the promotion certificate. The DBD Biz Regist is the current digital registration channel for companies; use the DBD company record and shareholder list required at BOI certificate issuance. Check Thailand company registration requirements as the entity baseline; activity-specific approvals remain separate.

This separation also matters for research equipment. BOI may approve machinery or raw-material import privileges for a promoted project, but a user must follow the certificate, approved list, customs procedures, and any other product or hazardous-material permission. An incentive approval is not permission to import or operate every item used in a laboratory. Do not ship chemicals, clinical products, or controlled equipment on the strength of a project approval alone.

If the operating plan is a contract lab, routine measurement service, or engineering design provider rather than a research project, revisit the activity classification and foreign-business position. The distinction matters even when the same scientists and equipment perform the work. A useful broader explanation is how incorporation and operating licences are separate checks ; keep the research-specific activity and permit questions in the project evidence rather than treating company registration as the finish line.

Sequence the BOI application and launch

Use the BOI process as a chain of dated decisions rather than one application date. Its 2026 Guide describes an e-Investment submission, project clarification, evaluation, result notification, acceptance of the resolution, and a later certificate-issuance application. The published review windows are measured after complete documents are submitted and vary by investment size; the Guide shows 40, 60, or 90 working days for the respective review route. It separately states that a certificate-issuance application is due within six months after resolution acceptance and that BOI issues the certificate within ten working days after receiving complete documents.

1. Freeze the project boundary. Confirm whether the Thai work is 10.2, a sector-specific activity, or a combination requiring separate applications. Identify revenue sources and excluded services.
2. Build the proof set. Reconcile researcher profiles, new-hire salary or eligible capital, process, equipment, collaborations, premises, and the three-year funding model.
3. Submit through e-Investment. Complete the activity-specific form and supporting documents. Arrange the clarification meeting and retain the submission record and questions.
4. Accept the resolution on time. BOI’s Guide gives one month after notification to confirm acceptance through the Promotion Certificate System. Track this separately from the certificate application.
5. Complete the certificate file. Submit the certificate form and current company certificate, shareholder list, utility and labor requirements, foreign-fund evidence when applicable, and activity-specific material within the stated six-month window.
6. Clear conditional operating approvals. Complete site, factory, substance, product, ethics, and other triggered permits before the corresponding regulated work starts.
7. Commission against the approved project. Match the installed equipment, hires, services, expenses, imports, and outputs to the certificate and project conditions; keep proof for BOI monitoring and tax use.

These are BOI service targets, not a guaranteed end-to-end opening date. The clock for R&D design, company formation, translations, landlord approvals, ethics review, FDA review, and controlled substances is separate. Do not build a launch date by adding only the BOI review window to the fit-out period.

There is a separate 2026–2027 integrated-relocation measure worth checking only if the project also includes an eligible manufacturing investment and an IBC. The current BOI measure is open for applications from the first working day of 2026 through the last working day of 2027; the manufacturing + IBC + R&D combination can add five years of CIT exemption, subject to the measure’s conditions and an overall maximum of eight years. It is not an extra five-year benefit for a standalone R&D center. The updated conditions appear on the BOI’s integrated relocation measure page ; review the Thai announcement and current BOI confirmation before relying on the window.

Choose the Thailand R&D center route

Use activity 10.2 when the Thai project will genuinely conduct basic or applied research, pilot development, or demonstration development and can document the researcher capability and one of its two project thresholds. If the primary deliverable is a paid test report, engineering plan, clinical research service, or commercial manufacturing output, screen the specific activity and operating permissions before presenting the operation as a generic R&D center.

Before committing to a long lease or importing equipment, put four items on one page: the BOI activity and project scope; the salary or capital route and its proof; the operational approval triggers for the planned workbench; and the entity, site, and launch sequence. Stop for a specialist authority review if the project will use controlled chemicals, trial products, human subjects, pilot-scale production, or a process that may fall under factory or local environmental rules. The right completion state is a matching BOI certificate, a registered operator, written evidence for each applicable permission, and a launch plan that starts only the cleared work.
