Thailand's Most and Least Durable Industry Codes in 2026
In short
Industry code 86202 keeps 99.97 percent of its 2,926 registered companies active, the highest survival rate of any Thai TSIC code with at least 400 firms, as of 7 July 2026. Code 03111 sits at the opposite extreme, with only 3.21 percent of its 468 companies still active. That is a 96.76 percentage point gap between two codes drawn from the same national registry. The national average active share is 50.0 percent, so both extremes sit far outside the typical range, and neither is named here, only numbered.
Which industry codes survive best, and which collapse
Among the 462 five digit TSIC codes with at least 400 registered companies, one code towers above the rest. Code 86202 keeps 2,925 of its 2,926 registered companies active, a survival rate of 99.97 percent, verified against market_tsic_insight as of 7 July 2026 (DBD, 2026). It sits inside section Q, human health and social work, yet that whole section only averages 73.9 percent survival. At the opposite end, code 03111 has lost nearly all its companies. Only 15 of its 468 registrations remain active, a survival rate of 3.21 percent. Code 03111 sits inside section A, agriculture, where the section average survival rate runs to 55.7 percent. Neither extreme resembles the sector it belongs to. The national average active share across all 1,986,709 registered companies is 50.0 percent, so both codes sit far outside the typical range. The DBD registry leaves the plain English description blank for every five digit code, so both are presented here by number only, never named.

Figures in percent of registered companies still active.
The top five codes cluster near total survival. The bottom five have shed more than nine in ten of their registrations, and three of the five sit in manufacturing.

Five highest and five lowest five digit TSIC codes by survival rate, limited to codes with at least 400 registered companies, as of 7 Jul 2026.
Why a code level story matters more than a section average
Section level statistics hide both of these stories completely. A reader who only sees that section Q averages 73.9 percent active would never guess that one code inside it keeps 99.97 percent of its companies going. A reader who only sees section A at 55.7 percent would never guess that one code inside it has shed 96.79 percent of its registrations. A separate ranking of Thai industry sections puts mining and quarrying at the bottom with 30.9 percent survival, yet the single worst performing code in this entire registry sits in agriculture, not mining, at just 3.21 percent. For an entrepreneur choosing which five digit code to register under, or a lender pricing risk by industry, the section average is not a safe stand in for the code. International agencies have tracked Thai SME survival as a policy indicator for over a decade (OECD, 2011). This registry shows why the code level, not just the section, is where that survival story actually plays out.
Definitions
- Survival rate
- The share of companies registered under a code that the DBD registry still marks active, expressed as a percentage of all companies ever registered under that code.
- Active company
- A company whose DBD registration status is not marked dormant, dissolved or deregistered.
- TSIC code
- Thailand's five digit Standard Industrial Classification code, the finest level of industry detail the registry publishes.
- Section
- One of 21 broad industry letters, such as Q for human health, that groups many five digit codes together.
- Aggregate
- A statistic built by summing or dividing totals across many companies, rather than describing any single firm.
Assumptions
- The ranking excludes any code with fewer than 400 registered companies so that a single closure or a single new filing cannot swing the rate to an extreme.
- Active status reflects the registry's status flag as of 7 July 2026 and does not confirm that a company is still trading or has filed a recent financial statement.
- description_en is null for every five digit code in the source table, so this page names sections only, never the sub industry itself.
Methodology
Survival rate is the share of companies registered under a five digit TSIC code that the DBD registry still marks active, as of 7 July 2026. Every one of Thailand's 1,228 codes was checked, but this page restricts its ranking to the 462 codes with at least 400 registered companies, so a rate is not swung toward zero or one hundred percent by a handful of firms. Section level figures, such as 73.9 percent for human health or 55.7 percent for agriculture, are separate aggregates built by summing every code inside that section. The DBD registry does not publish a plain English name for five digit codes, so codes are identified here only by number and by the broader section letter they belong to.
How we verified this
- 2,925 active divided by 2,926 total at code 86202 equals 99.966 percent, which rounds to 99.97 percent, matching the survival_rate column.
- 15 active divided by 468 total at code 03111 equals 3.205 percent, which rounds to 3.21 percent, matching the survival_rate column.
- 993,373 active divided by 1,986,709 total registered companies equals 50.001 percent, matching the national anchor of 50.0 percent.
- Section Q totals 12,778 active of 17,294 companies, 73.89 percent, confirmed as far below code 86202's own 99.97 percent even though the code sits inside that section.
- Section A totals 10,729 active of 19,259 companies, 55.71 percent, confirmed as far above code 03111's 3.21 percent even though the code sits inside that section.
- The gap between the highest and lowest code survival rate was recomputed as 99.97 minus 3.21, equal to 96.76 percentage points.

Frequently asked questions
Which Thai industry code has the highest company survival rate?
Code 86202, inside section Q for human health and social work, keeps 99.97 percent of its 2,926 registered companies active, the highest of any code with at least 400 companies.
Which Thai industry code has the lowest company survival rate?
Code 03111, inside section A for agriculture, has only 3.21 percent of its 468 registered companies still active, the lowest of any code with at least 400 companies.
Why not just look at the industry section instead of the code?
The section average hides the extremes. Section Q averages 73.9 percent survival and section A averages 55.7 percent, both far from the single codes that sit at the true top and bottom.
Why does this page not name the actual sub industry behind each code?
The DBD registry leaves the plain English description blank for every five digit code, so codes are reported here only by number and by the broader section they sit in.
