Thai Industry Codes That Lost the Most Companies, 2015-2025
In short
TSIC 60101 lost 1,065 filing companies between 2015 and 2025, the steepest company count decline of any 5-digit Thai industry code with matched data. The count fell from 2,797 to 1,732 over the decade. TSIC 92001 lost fewer filers in raw terms, 754, but fell a sharper 66.37 percent. Thailand's whole filing base still grew 49.05 percent over the same years. Of 938 codes with data in both 2015 and 2025, only 140 shrank at all. This page is the mirror image of the site's fastest-growing industry codes ranking, which covers the same decade from the opposite direction.
Which industry code lost the most companies between 2015 and 2025?
TSIC 60101 answers the question outright (DBD, 2026). This five digit code, filed under the information and communication section, had 2,797 companies submit a financial statement in 2015 and only 1,732 in 2025. The code lost 1,065 filers over the decade, a 38.08 percent decline. No other five digit code with matched data in both years fell by more filers. The runner up, TSIC 92001 in arts, entertainment and recreation, dropped from 1,136 filers to 382. That is a steeper 66.37 percent fall, even though its raw loss of 754 filers puts it in second place behind TSIC 60101. Thailand's entire filing company base still grew 49.05 percent over the same decade, rising from 478,547 to 713,280. TSIC 60101 and TSIC 92001 both moved against that current.

Figures in filing companies lost, 2015 to 2025.
Every code shown lost more than 160 filers over the decade, a real decline measured in whole companies, not a rounding artifact of a tiny starting base.
The ten industry codes that lost the most filing companies
| TSIC code | Section | 2015 filers | 2025 filers | Companies lost | Percent change |
|---|---|---|---|---|---|
| 60101 | J, Information and communication | 2,797 | 1,732 | 1,065 | -38.08% |
| 92001 | R, Arts, entertainment and recreation | 1,136 | 382 | 754 | -66.37% |
| 18119 | C, Manufacturing | 3,532 | 3,061 | 471 | -13.34% |
| 64999 | K, Financial and insurance | 816 | 588 | 228 | -27.94% |

Filing companies by 5-digit TSIC code, 2015 versus 2025, as of 17 Jul 2026.
Two of the ten sit in the same section
The registry does not publish an activity name for any five digit code, so this page identifies TSIC 60101 and TSIC 92001 only by number and section, never by an inferred activity. Section J, home to TSIC 60101 and the eighth placed code TSIC 59112, covers publishing, broadcasting, telecommunications and computer services together. Thailand's broadcasting regulator has spent 2026 rebuilding radio's digital infrastructure, proposing a national online platform for licensed stations, a sign that pressure on the older parts of this section is real even if this dataset alone cannot pin the decline to one specific business line (Bangkok Post, 2026). Section R, home to the second placed code, fares worse on a separate measure. Only 15.46 percent of the 4,555 companies ever registered under TSIC 92001 remain active today. TSIC 60101 does a little better, with 43.44 percent of its 4,945 all time registrants still active. Both figures sit well below the site's fastest-growing code by company count, TSIC 47912, which keeps close to four in five of its registrants active.
Why this matters
TSIC 60101 and TSIC 92001 are not isolated. They sit inside a small minority of the register that is contracting while the surrounding economy keeps expanding. Of the 938 five digit codes with matched filings in 2015 and 2025, 782 grew and 16 stayed flat, leaving only 140 codes, 14.93 percent, in decline. A company count ranking answers a different question than a revenue ranking. A code can lose more than a thousand filers and still matter economically if the survivors are larger, or it can shrink because the underlying activity is fading. The site's revenue decline ranking is led by a different code entirely, TSIC 61209, which also sits in section J, so section J carries both the steepest count decline and the steepest revenue decline on this site, from two different five digit codes. For anyone tracking where Thailand's company register is actually contracting, TSIC 60101 and TSIC 92001 are the two codes to watch first.
Definitions
- TSIC
- Thai Standard Industrial Classification, a hierarchy of codes that groups companies by economic activity. A 5-digit code is the most detailed level and sits inside one of 21 lettered sections.
- Filing company
- A company that submitted a financial statement to the DBD for a given statement year. Not every registered company files every year.
- Statement year
- The Buddhist calendar year the DBD registry uses to timestamp a filed financial statement. Buddhist year 2558 corresponds to Gregorian year 2015, and 2568 corresponds to 2025.
- Survival rate
- The share of every company ever registered under a code that remains active as of the data date, a different measure from the year by year filing counts used for the 2015 to 2025 comparison.
- Percent change
- The difference between two counts divided by the earlier count, shown as a percentage. A negative value marks a decline.
Assumptions
- Company counts here measure filing companies per statement year, not every company ever registered, so a falling count can reflect fewer filers as well as fewer surviving registrations.
- Only codes with filings in both statement year 2558 and statement year 2568 are compared, codes with data in only one of the two years are excluded from the 938 code universe.
- Five digit code names are not published in the source data, so TSIC 60101 and TSIC 92001 are identified only by number and parent section, never by an inferred activity name.
- The Bangkok Post reference provides context for pressure inside section J broadly, it does not confirm the specific activity of TSIC 60101.
Methodology
Filing company counts are drawn from market_tsic_year_insight, which counts companies that filed a financial statement under each 5-digit TSIC code for a given statement year, sourced from the DBD registry. The 2015 figures use Buddhist calendar statement year 2558 and the 2025 figures use statement year 2568, both refreshed as of 17 July 2026. The ranking covers all 938 five digit codes with filings recorded in both years. No minimum base filter was applied since the ranking is by raw count lost, and a large raw decline already requires a large starting base. Section labels come from the fixed 21 letter TSIC section list. Five digit code names are not published in the source data, so codes are identified by number and parent section only, never by an inferred activity name. Active and inactive counts and survival rate come from market_tsic_insight and reflect every company ever registered under a code as of the data date, a different measure from the year by year filing counts used for the 2015 to 2025 comparison.

Frequently asked questions
Which Thai industry code lost the most companies between 2015 and 2025?
TSIC 60101, a five digit code inside the information and communication section, fell from 2,797 filing companies in 2015 to 1,732 in 2025, a loss of 1,065 filers, the largest raw loss of any code with matched data in both years.
Did most Thai industry codes shrink over the past decade?
No. Of 938 five digit codes with filings in both 2015 and 2025, 782 grew and only 140 shrank, so decline sat with a small minority of codes while the whole filing base grew 49.05 percent.
Is this the same code that leads the site's revenue decline ranking?
No. That ranking is led by TSIC 61209, which lost 98.4 percent of its revenue over the same decade. TSIC 61209 also sits in section J, so section J holds both the steepest count decline and the steepest revenue decline, but from two different codes.
What does the DBD registry mean by a filing company?
A company that submitted a financial statement for that statement year. It is a narrower count than every company ever registered, since not every registrant files each year.
