IoR / SoR Explained

Why local sales in Korea are possible without an entity — a ground-up explanation of the legal basis and mechanics of the Importer of Record / Seller of Record structure.

~6 min read Based on Korea's Customs Act and the Act on Consumer Protection in Electronic Commerce As of 2025

What are IoR and SoR

The two terms refer to separate legal roles under Korea's customs and e-commerce rules. Understanding them without confusion is the starting point.

IoR
Importer of Record — the official importer
The entity or individual listed as the official importer on the import declaration when goods clear Korea Customs. It bears the obligation to pay customs duty and import VAT, and if a product is defective, recall liability also falls on the IoR.
Customs Act Article 241 — the party obligated to file the import declaration. The importer must be a Korean entity holding a business registration number or a Customs Clearance Code.
SoR
Seller of Record — the official seller
The entity registered as the party that actually sells to consumers on marketplaces (Coupang, Naver, 11st, etc.). As the seller under the Act on Consumer Protection in Electronic Commerce, it bears the obligations for refunds, customer service, and affixing certification labels.
Act on Consumer Protection in Electronic Commerce, etc. Article 12 — the obligation to file an Online Retail Business Declaration. A Korean business address is required.

Key point

The IoR and SoR can be held by the same entity or by different entities. When an overseas brand enters Korea without a local entity, the structure works by having a third-party local entity perform both roles on its behalf. This is the legal basis for the IoR/SoR agency service KONIVO provides.

Legal obligations sit with the local entity Customs duty, VAT, recall, and customer-service liability are all borne by the IoR/SoR entity
Brand ownership stays with the overseas brand Decisions on product planning, pricing, and marketing remain with the original brand
The relationship is set out in a contract The scope of liability and ownership must be spelled out in the contract with the IoR/SoR agency

Why this structure is necessary

Korean marketplaces do not allow overseas entities to sell directly. This is not a platform policy but a legal requirement.

1
Korean marketplaces only allow Korean businesses to list
Major platforms such as Coupang, Naver Smart Store, 11st, and SSG only let entities holding a Korean business registration number open a seller account. A direct seller account for an overseas entity is not possible.
2
Every import requires a registered official importer
When filing an import declaration with Korea Customs, you must designate an entity or individual with a Korean business identification number as the importer (IoR). Without an import declaration, customs clearance is not possible.
A Personal Customs Clearance Code (for ordinary consumers) cannot be used for B2B commercial imports
3
Online Retail Business Declaration required under the E-Commerce Act
Every seller (SoR) that sells directly to consumers must file as an online retail business with the Korea Fair Trade Commission. A Korean address and a Korean business number are required.
4
Category certifications are obtained under the IoR's name
All product certifications — food (HACCP), health functional food (GMP), electronics (KC certification), cosmetics (INCI ingredient filing), and so on — are obtained by the Korean entity (i.e., the IoR). An overseas brand cannot obtain them directly.
Certification lead time: 2 weeks to 6 months depending on the category
5
Conclusion: legal market entry is not possible without an IoR/SoR structure
To start local sales on Korean marketplaces without setting up a separate Korean entity, you must have a local partner that performs the IoR/SoR roles. This is a legal requirement, not an option.

The legal relationships in the IoR / SoR structure

The IoR/SoR structure is a contractual arrangement that clearly separates legal responsibility among three parties: the overseas brand, the local agency (IoR/SoR), and the Korean consumer.

Overseas brand
Holds product and trademark ownership
Sets pricing and strategy
No legal status in Korea
IoR / SoR
agency
Korean consumer / marketplace
Subject to Korean law
Buys on the marketplace
Entitled to Korean-language customer service
Separation of legal liability

The IoR/SoR agency is listed as the party legally obligated for import and sale. The overseas brand is insulated from Korean administrative and tax obligations.

Brand ownership preserved

Even though registration is in the agency's name, trademark and product ownership belong 100% to the original brand. This is set out in a brand ownership agreement.

Contract-based structure

The IoR/SoR structure is legally valid only when three agreements between the brand and the agency are executed together: a delegation agreement, a brand ownership agreement, and a settlement agreement.

The core legal principle of the IoR/SoR structure

IoR and SoR are separate legal statuses. The same entity can perform both, but the "importer" under the Customs Act and the "online retail business" under the Act on Consumer Protection in Electronic Commerce are independent obligations grounded in different laws. Confusing the two roles can create legal gaps in certification, customs clearance, and consumer dispute handling.

When you need an IoR / SoR structure

Not every overseas brand has to choose this structure. Depending on the situation, a different entry structure may be a better fit.

When IoR / SoR is a good fit
  • You have no Korean entity and want fast market entry before setting one up
  • Your annual Korea revenue target is under KRW 500 million, so entity setup is not cost-efficient
  • You are testing and validating the Korean market (before confirming product-market fit)
  • You do not want to build local hiring, accounting, and tax infrastructure yourself
  • A sales strategy centered on specific marketplaces such as Coupang and Naver
  • You need local inventory and immediate delivery rather than global direct shipping (CBEC)
When separate review is needed
  • Annual Korea revenue is already over KRW 2 billion — your own entity is more efficient
  • You plan to build a local team, offline distribution, and independent distribution channels over the long term
  • You are in a regulation-sensitive category (pharmaceuticals, medical devices, alcohol) where obtaining licenses directly is essential
  • You ship directly to Korean consumers under a global direct-shipping (CBT) model
Full comparison of entry structures
Plan A — IoR/SoR agency
Start immediately without an entity. KONIVO acts as Importer of Record and Seller of Record.
Plan B — joint venture (JV)
Shared equity between the brand and KONIVO. A mid-to-long-term growth structure.
Plan C — branch office
A 100%-owned branch of the parent company. No Korean legal personality.
Plan D — entity setup
An independent Korean entity. Full local control.

Legal risks and precautions to know

These are risks a brand must understand and pin down in the contract when choosing an IoR/SoR structure.

Risk Level Description Mitigation
Breach of contract by the IoR/SoR High Risk that the agency uses sales proceeds at its own discretion or delays settlement Escrow payment or a weekly settlement agreement, plus securing joint view access to the brand's accounts
Ownership of certifications High KC and food certifications obtained under the IoR's name may not be transferable when the contract ends Spell out a certification transfer clause in the contract and agree the transfer process (30 days) in advance
Ownership of marketplace accounts High Coupang and Naver accounts are owned by the IoR/SoR entity, so the brand may lose account access Register the brand as a joint account administrator, plus a transfer guarantee agreement (KONIVO's 30-Day Transfer Guarantee)
Product recall liability Medium If a recall occurs, the IoR (KONIVO) bears primary liability; how cost recovery is pursued must be agreed in advance Take out product insurance and clarify product-liability terms in the contract
Misunderstanding the tax structure Medium A permanent establishment (PE) issue may arise even if the brand has no substantive management activity in Korea Review by a tax accountant and establishment of a transfer pricing policy
Difficulty controlling pricing Low The SoR independently decides to discount prices or sell bundles Include the pricing policy (MAP/MRP) as a contract term

Common misconceptions about IoR / SoR

Misunderstandings often make brands hesitate to enter — or, conversely, hold the wrong expectations.

Myth: "It's a losing deal because the IoR/SoR agency takes a cut of the revenue."
Fact: IoR/SoR agency fees are typically 10–18% of sales. Once you factor in entity setup and maintenance costs (KRW 30 million–100 million+ per year), local hiring, and tax and legal expenses, it is a far more cost-efficient structure in the early stage.
Myth: "The IoR/SoR agency ends up owning my brand."
Fact: IoR/SoR is an operational agency role. Trademark rights, product IP, and pricing authority belong to the original brand. Setting this out in a Brand Authorization Agreement protects it legally.
Myth: "Direct sales to Korea (personal-import purchases) are possible, so IoR/SoR isn't needed."
Fact: You can send some items directly to consumers via global direct shipping (CBEC). But in that case you cannot list on the major marketplaces (Coupang, Naver), and the list-clearance threshold (USD 150 or less per shipment) and category restrictions are strict. Serious market entry through local sales requires an IoR/SoR structure.
Myth: "If you switch IoR/SoR agencies, you have to start everything over from scratch."
Fact: Whether certifications, marketplace accounts, inventory, and review assets can be transferred is determined by the contract. KONIVO includes a transfer guarantee clause (the 30-Day Transfer Guarantee) in its standard contract. Always check the transfer clause before signing.

IoR / SoR FAQ

The concept questions brands ask most often.

Q. Do the IoR and SoR have to be the same entity?
No. The IoR (importer) and SoR (seller) are legally separate roles and can be held by different entities. For example, a logistics company could act as IoR while a distributor acts as SoR. That said, KONIVO performs both roles through a single entity to keep the contractual relationship simple.
Q. How are Korean taxes handled in an IoR/SoR structure?
Customs duty and import VAT are paid by KONIVO (the IoR), and the amounts paid are included in product cost and billed to the brand. Marketplace sales VAT (10%) is filed and paid by the SoR. The brand's head office only needs to handle home-country tax on the settlement amounts it receives from KONIVO. However, we recommend a tax accountant review whether the head office could be deemed to have a permanent establishment (PE) in Korea.
Q. What is the term of an IoR/SoR agency contract?
KONIVO's base contract term is a minimum of 6 months, renewing automatically thereafter. On termination, after 30 days' advance notice, we guarantee that the transfer of all assets — certifications, accounts, inventory, and so on — is completed within 30 days. The transfer guarantee is stated in the contract.
Q. Can the IoR/SoR structure be applied to every product category?
It can be applied to most consumer goods (cosmetics, food, health functional food, electronics, fashion, pet products, and so on). However, highly regulated categories such as pharmaceuticals, medical devices, alcohol, and tobacco have separate licensing requirements and need review in advance. KONIVO offers a regulatory assessment service for those categories.
Q. When converting from IoR/SoR to your own entity, can all assets be transferred?
It depends on the contract terms, but KONIVO's contract explicitly guarantees the transfer of transferable assets (marketplace accounts, certificates, inventory, reviews and ratings). If you are converting to independent operation after setting up an entity, KONIVO also offers entity setup support as a parallel service.
