Foreign Business Act restricted list screening worksheet

In short

Thailand sorts the businesses it restricts for foreigners into three lists: List 1 is prohibited outright, List 2 needs cabinet-level approval and carries Thai shareholding requirements, and List 3 needs only a licence. Manufacturing is generally not on the lists, but trading, retail and service activities have to be checked item by item — this worksheet turns that item-by-item check into a working sheet you fill in together with an adviser.

01The line is usually crossed later, not at registration

The restricted lists do not decide whether you can come to Thailand. They decide whether foreign capital can run this particular business on its own, whether a licence is needed, and whether a Thai shareholder has to sit in the structure. That drives how the registered business scope is worded, how the shareholding is built, and whether you need a licence route or a promotion route.

What actually costs companies money is not the rule itself but its timing: a business scope that was clean at registration is not necessarily clean later. The line tends to be crossed after one of these moves.

What these have in common: they happen when the company is already operating. Fixing them costs far more than getting it right before registration — which is exactly what this worksheet is meant to head off.

02What the four tabs cover

Four tabs, and the second one is the main sheet.

03Three things that get checked wrong

Three points account for most of the wrong conclusions we see.

04This worksheet is filled in by two people

Every cell that turns on the facts of the case is left as an amber blank: whether a threshold exception applies, whether a separate licence is needed, which list the activity finally falls under. A download cannot answer those for you. What it gives you is the order to check things in and the questions to ask; the answers get written in.

The practical way to use it is in three steps. First, list line by line what you intend to do over the next two or three years, not only what you do today. Second, check each line against the lists and mark it as not on the lists, as List 3 needing a licence, or as a higher list. Third, for anything needing a licence or otherwise restricted, work out whether to apply for the licence, take a promotion route, or adjust the boundary of the business. Do this once before registration, and again every time you are about to add to the registered scope.

One situation is worth stating separately. If a nominee arrangement is already in place, the order is establish the facts as they stand, then assess the level of risk, then design a transition — and defuse it before a capital increase, an acquisition, a financing round or a promotion application. Rearranging the shareholding yourself and papering it over afterwards is not advisable: done in the wrong order, it can leave a trail that is harder to explain.

Which list your own business falls under, whether an exception route applies, and whether your existing registered scope already contains something over the line all have to be checked line by line against your specific business description and registered scope, and confirmed by our advisers before a formal opinion is issued.

What is in the workbook

  • Three-list quick reference: the entry rule, additional requirements, typical activities and whether an exception route exists for each list, on one screen; the last two rows are the two further judgement calls, how a business format is classified and who counts as a foreigner
  • Line-by-line screen of the business scope (the main sheet): copy out the registered scope line by line, then fill in the exception route, whether a separate licence is needed, and the adviser's conclusion on which list it falls under; the pre-filled entries are only a starting point, so delete the whole row where it does not apply
  • Exception routes and red lines: the lawful routes listed one by one, each marked as answering either how much foreign capital may hold or whether the business may be done at all; nominee shareholding has its own row, marked as not a route
  • Re-screen triggers: which events require the screen to be run again before they happen, with four columns per row for planned date, internal deadline, owner and status
  • Amber cells mean the point has to be determined by an adviser on your own company's facts, not copied from a template default

Common questions

We are a manufacturer — do we still need to fill this in?

Yes. Manufacturing is generally not on the lists, but that is a statement about the industry, not a ruling on each line of your registered business scope. And the most common crossings are not in manufacturing itself: they are selling directly to local customers, distributing other group products, and starting after-sales and technical service. Only a line-by-line check tells you whether anything is already over the line.

Why are so many cells in the workbook empty?

Because they turn on the facts of the case. Whether a threshold exception applies, whether a separate licence is needed and which list the activity finally falls under all depend on your specific business description and registered business scope, and a template default would mislead rather than help. Those cells are marked amber and are there for the adviser to fill in once determined — the sheet is a working paper, not an answer.

We hear Thailand is relaxing its restrictions on foreign investment. Can we structure around the new rules now?

First establish which change is meant and how far it has got. The reform initiative is still under review, the draft amendment approved by the cabinet has not been gazetted and is not in force, and the reclassification of particular industries is still at draft and hearing-preparation stage — each item sits at a different legislative stage. Making structural decisions on a draft that is not yet in force is an expensive mistake.

We already use a Thai nominee shareholder. Is this worksheet still any use?

It is, and the order matters. Use the sheet to check the business line by line first: a fair number of nominee holdings were put in place for a restriction that never applied. Once you know which activities are unrestricted as they stand and which have a lawful route, then assess the level of risk and design a transition. Rearranging the shareholding yourself and papering it over afterwards is not advisable — done in the wrong order it can leave a trail that is harder to explain.

  1. General note: the structure of the three restricted lists, the level at which each is approved and the entry thresholds follow the Foreign Business Act and its schedules. The provision prohibiting Thai nationals from acting as nominee shareholders to help a foreigner get around the shareholding limits, its penalties (including imprisonment and fines, with the court able to order the nominee relationship terminated) and the joint liability of directors who knowingly allowed it follow the relevant provisions of that Act.

This workbook is a working paper for an adviser and a client to complete together. It is not a market-access determination for any particular business, and not a legal opinion on an existing structure; individual cases have to be verified by our advisers against the business description, the registered business scope, the shareholder composition, the capital contribution records and the existing agreements before a formal written opinion is issued.
