Hiring a Vietnamese Celebrity Brand Ambassador: Process and Terms
Hiring a brand ambassador in Vietnam is a different decision from booking a KOC. You are buying a face, a long-term association and the right to use that face across media, so the process is slower, the contract is heavier and the risk sits with your brand name. This guide walks through when a celebrity makes sense, the steps from shortlist to signature, the terms to lock, and the advertising-law duties that applied to celebrities from 1 January 2026.
Short answer
How do you hire a celebrity brand ambassador in Vietnam?
Define the goal and budget first, shortlist celebrities whose audience and reputation fit the product, contact their management, then negotiate a written contract covering term, appearances, image rights by medium, exclusivity, approval and a morality clause. Since 1 January 2026, Article 15a of the Advertising Law also requires the celebrity to understand the product and disclose the ad.
- Decide the goal: awareness, trust or launch moment
- Shortlist by audience fit and reputation, not follower count alone
- Approach through management, with a one-page brief
- Price image rights by medium, term and territory
- Lock exclusivity, approvals and a morality clause
- Back the deal with KOC coverage so reach turns into proof
1. What is a brand ambassador in Vietnam, and how is it different from a KOC booking?
A brand ambassador is a public figure, such as a singer, actor, presenter or athlete, who represents a brand over a defined period. Unlike a one-off KOC video, the deal usually bundles appearances, content, image rights for several media and a promise not to represent competitors.
That bundle is why the booking works differently. A KOC campaign buys many small, credible voices. An ambassador deal buys one large, recognisable association, and the contract has to protect it.
2. When does a celebrity ambassador make sense, and when should KOCs come first?
A celebrity makes sense when the goal is broad recognition or a launch moment and the budget can carry both the fee and the media that amplifies it. Korean brands often default to a Vietnamese celebrity because that is how marketing works at home, but the Vietnamese buyer on TikTok Shop or Shopee often trusts a peer review more than a famous face.
For a brand with little local awareness and a limited budget, build KOC coverage first. It shows which message and product convert, and then a celebrity can amplify something already proven.
- Choose a celebrity when you need fast awareness, retail or OOH presence, or a premium signal
- Choose KOCs first when you need reviews, sales proof or message testing
- Combine both when the budget allows: face for reach, KOCs for proof
3. How do you shortlist the right celebrity?
Shortlist on fit, not fame. A celebrity whose audience does not buy your category wastes the fee, and a celebrity with a messy reputation can damage the brand.
Score each candidate on a simple sheet before any contact.
- Audience fit: age, gender, city and the products their fans already buy
- Reputation: search their name for past controversies and past brand deals
- Category conflicts: who else they currently represent
- Content style: does their feed carry branded content naturally
- Availability and appetite: can they commit to the appearance days you need
4. What is the step-by-step process from shortlist to signature?
Expect a longer cycle than a KOC booking, because management, legal review and image approval are involved. Plan the steps in order so nothing is negotiated twice.
Start the legal review early, since the contract is where most of the real work sits.
- Step 1: write a one-page brief with goal, period, media plan and budget range
- Step 2: shortlist three to five candidates and check reputation
- Step 3: contact the manager or talent company, not the celebrity directly
- Step 4: exchange a term sheet covering scope, term and fee structure
- Step 5: negotiate the contract with legal review on both sides
- Step 6: sign, schedule shoots and appearances, and prepare approvals
- Step 7: launch, report and decide whether to renew
5. Which contract terms must you lock?
The contract is the product. A fee buys nothing specific unless the clauses say what the brand gets, for how long and where. Our influencer contract checklist covers the general clauses; ambassador deals add the following.
Write each one as a specification, not an intention.
- Term and renewal: start date, end date and any option to extend
- Appearances and content: number of shoot days, events and posts, with dates or windows
- Image rights: which media (digital, OOH, TV, packaging, in-store), which territory and for how long
- Exclusivity: which competing categories are blocked, and for how long after the term ends
- Approvals: who approves scripts, photos and edits, and how fast
- Morality clause: the brand may suspend or end the deal if public conduct damages its reputation
- Termination and kill fee: what happens, and what is owed, if either side exits early
6. How should image rights and usage be priced and written?
Image rights are separate from the appearance fee, and each medium is a separate right. Using a celebrity face on a billboard, in a TV spot and in paid social ads are three different uses with different reach and different cost.
State the medium, the territory, the duration and whether edits are allowed. If you plan to run the celebrity content as ads from their account, the same logic applies as in whitelisting.
7. What does Vietnam's 2026 advertising law require of a celebrity?
Article 15a of the Advertising Law, added by Law 75/2025/QH15 and in force from 1 January 2026, sets duties for influencers. As the text of Law 75/2025/QH15 and our law guide set out, an influencer must verify the advertiser and the product documents, must not present a product they have not used or do not clearly understand, and must announce the advertisement immediately before and during it.
Decree 55/2024/ND-CP defines an influencer as a person with specialist standing, reputation or the ability to attract social attention who is sponsored by a business to use their image or recommendations. A paid celebrity endorsement fits that description. Penalties are set in Decree 87/2026/ND-CP: up to 100 million VND for an individual and double for an organisation.
8. How should you brief a celebrity so the law is met?
Because the duty to understand the product now sits with the celebrity, give them what they need to meet it: product samples, ingredient and claim documents, and time to use the product before filming. Keep a record that you provided them.
Put the disclosure format in the contract and in the shoot brief, so every post and clip carries it from the first draft rather than after a complaint.
- Send samples and documents before the shoot, and keep the delivery record
- Brief only claims you can prove from your own documents
- Specify the exact disclosure wording or label for each medium
- Ask the talent company to confirm that the celebrity has used the product
9. How should payments and tax be handled?
Pay in instalments tied to milestones, such as signature, shoot completion and launch, rather than all at once. This protects both sides and gives you leverage if deliverables slip.
On tax, a summary on Thuvienphapluat of Decree 253/2026/ND-CP (Articles 50, 58 and 61) states that from 1 July 2026 a payer paying remuneration of 5 million VND or more per payment to a resident individual without a labour contract, or with one under three months, must withhold 10% personal income tax. Whether it applies depends on how the celebrity contracts, individually or through a company, so confirm with your accountant.
10. How do you measure an ambassador deal?
Set the measures before signing, not after launch. An ambassador is a reach and trust investment, so measure branded search, content views, store or marketplace traffic during the campaign, and the sales shown by tracked links or codes.
Pair it with KOC content using the same message so you can see whether the celebrity lifts the conversion of the proof content rather than only generating views.
FAQ
Frequently asked questions
How do I contact a Vietnamese celebrity for a brand deal?
Go through their manager or talent company, not their personal messages. Send a one-page brief with the goal, period, deliverables and budget range, and expect a term sheet exchange before the full contract.
How long does a brand ambassador contract usually run?
The term is whatever the two sides agree and write down, from a single campaign to a year or more. Set a clear start and end date, and add an option to renew only if the first period meets agreed measures.
Does the 2026 advertising law apply to celebrities?
Yes, where a celebrity is sponsored by a business to promote a product they fit the influencer definition, so Article 15a duties apply: verify the advertiser and product documents, understand the product and announce the ad before and during it.
Is a celebrity better than KOCs for a Korean brand entering Vietnam?
Not by default. KOCs show which message converts and build reviews, and a celebrity amplifies a message that already works. Many launches use both, with KOCs first when the budget is limited.
What is a morality clause?
It lets the brand suspend or end the deal, and sometimes recover fees, if the celebrity's public conduct seriously damages the brand's reputation. Define the triggers and the process clearly so both sides know what applies.
