TikTok Seller Vietnam: Read the Shops in Your Niche First

Before you register as a TikTok Seller in Vietnam, look at the shops already standing in your niche. Public data shows which shops are selling, their prices, units sold and ratings. From that you settle three things: how you will sell, what you offer that existing shops lack, and when to stop.

What does this post not answer, and what does it answer instead?

This post does not walk you through registration, paperwork or fees. Those change over time, and the right place to read them is the official seller pages of TikTok Shop Vietnam.

Only two procedural points are kept, because they can be checked on official pages:

• According to TikTok Shop Vietnam's Seller University page (checked 28 Oct 2026), an individual seller must be a Vietnamese citizen aged 18 or over; a business must be registered in Vietnam.
• According to TikTok Shop Vietnam's seller page (checked 28 Oct 2026), there is no setup fee to join.

Fees and per-order commission are published by TikTok and can change. Read them on the official page before you price anything.

What do the shops in your niche look like?

The fastest way to see who stands in a niche is to run TikTok Shop Radar with a keyword describing the product you plan to sell. Each run costs 15 credits and reads 3 result pages for one keyword. For each product the tool returns the name, price, units sold, rating, review count and shop name. The summary gives total units sold, the lowest, median and highest price, and a table of the 5 shops with the most units sold in the results.

The question to answer from that leaderboard is concentration: do one or two shops hold most of the units sold, or are sales spread across many shops? A niche with twenty shops can still be held almost entirely by one.

Illustrative example, not real data. We have not run the tool for this keyword; the numbers below are made up only to show how to read the output. Say that for the keyword "matte liquid lipstick" the summary shows 80,000 units sold across all results. Shop A has 40,000, shop B has 25,000, and each remaining shop in the table has a few thousand. The top two hold about four-fifths of units sold. Now say the keyword "mixed rice paper salad" gives leading shops between 6,000 and 9,000 each: sales are spread out, and nobody owns the niche yet.

You have to guess the type of shop yourself: a familiar name, many products under one label and tens of thousands of reviews usually point to a large shop. The tool does not tag any shop as "brand" or "small shop".

One note when reading: "units sold" is a cumulative count since the product was listed, not this month's figure. An older shop always looks bigger than a new one, even when the new one is selling faster this month.

Video, live or KOC: what do existing shops rely on?

TikTok Shop Radar does not tell you whether a shop's orders come from videos, live sessions or KOCs (key opinion consumers — creators with smaller audiences than KOLs but closer to buyers). To guess, you combine other tools, and the result is still inference, not measurement.

Live Radar (10 credits per run) reads up to 5 channels, or 20 rooms when searching by keyword. It shows whether a room is live, how many viewers it has and whether products are attached. Each run is only a snapshot of one moment, so run it at several time slots; for choosing them, see TikTok live time slots.

Find KOC (15 credits per run, 3 result pages) shows which channels are making content about the niche. Comments analysis (12 credits per run, up to 300 comments) shows whether viewers are asking for the price, asking for the link, or just watching for fun. If you plan to have KOCs sell for you, the post on picking creators for affiliate goes deeper.

How to sell	Signs in the niche	Tool to look with	What you need
Live	Many rooms found by niche keyword are live, have products attached and have viewers	Live Radar	Someone who goes live regularly, fixed time slots
Self-shot video	Channels in the niche get comments asking to buy	Find KOC, Comments analysis	Someone who films steadily, a source of ideas
Via KOCs	Many small channels make content about the niche	Find KOC	Sample stock, a commission rate you can afford

If at peak hours many rooms for your niche keyword are live with products attached, live may be the main channel. Empty rooms suggest the opposite. Pick one way to sell as your main channel and test it; doing all three at once with a new shop's resources usually means doing all three halfway.

What do you have that these shops lack?

The second decision is a comparison: the shop data gives you a list of gaps, then you set it against what you actually have. Three kinds of gap can be read from TikTok Shop Radar results:

• Best-selling products with low ratings. A product that leads on units sold but rates lower than the rest suggests buyers still buy because there is little choice.
• Few shops with many reviews. If only a handful of shops have a meaningful number of reviews, buyers do not yet have many names to trust.
• An empty price band. Compare the lowest, median and highest price in the summary. If products cluster at both ends and the middle is thin, that is a band worth testing.

Then write down what is yours: a supply source, a face or voice that can carry a video, the live hours per week you can manage, how you handle returns. Each line only counts if it matches a gap above: a cheap supply source in a low price band that is already crowded does not count.

To dig into a specific niche, including what customers complain about, see researching a niche on TikTok Shop. If you do not yet know what to sell, start with best-selling products on TikTok Shop.

When should you stop, even before registering?

Write your stopping thresholds on paper before you run the tool, because if you set them after seeing the data it is easy to read the numbers the way you want them to read. Three yes/no questions; each "yes" is a stop signal:

1. Do one or two shops hold almost all the units sold in the results?
2. Did you leave every box in the gap comparison empty?
3. Is the way you chose to sell completely absent from the niche?

This post gives no threshold like "stop if the top two shops hold more than X percent", because no source gives a figure that fits every niche. What "almost all" means is for you to set for your niche and your budget, and then keep.

Also set a spending cap for the research. Each keyword on TikTok Shop Radar is one run, so two keywords cost twice as much as one. When you hit the cap, stop researching and decide. Stopping is a valid outcome: a few research runs are still cheaper than a batch of stock bought for the wrong niche.

Once you have decided, what next?

If all three decisions come out "continue", follow the launch checklist for a TikTok Shop to prepare before your first product. Once you have stock, the post on reading TikTok Shop data covers how to track the numbers next. Other posts on this theme are under the TikTok Shop topic.

What does this data not tell you?

Every number in the tools above is an estimate from what the platform shows publicly. They are not a shop's real revenue and not the figures in a seller's management dashboard.

TikTok Shop Radar reads 3 result pages for one keyword, not every shop on the market. A large shop in the niche may still not appear if it names its products with different words from the ones you typed. "Units sold" is cumulative from the start, so it does not tell you whether the niche is rising or falling.

The tools do not classify shops, do not tell you whether orders come from video, live or affiliate, and have no profit and loss or return rate. Live Radar only shows, at the moment it runs, whether a room is live, how many viewers it has and whether products are attached; it does not rank live-session revenue. No tool predicts whether you will sell; what they can do is help you rule out early the niches and ways of selling that clearly do not suit you.

TikTok Shop Radar returns shops and products, that is, business entities. Find KOC, Comments analysis and Live Radar touch public personal accounts. An account owner can send a request to delete data about them, or object to analysis of their account, through the data request page; an account that has requested a block is rejected before any credits are charged.

Frequently asked questions

Can an individual sell on TikTok Shop? An individual seller must be a Vietnamese citizen aged 18 or over, as the Seller University page above states. For the other requirements of the application, read that page directly.

Can a new shop compete with a large one? There is no general answer. Measure how concentrated units sold are in the niche, then look for the gaps the large shops leave that you can fill.

How many keywords should I research before deciding? Two to three keywords that describe the same product the way buyers tend to type it. Each keyword is one run at 15 credits.
