Origin Verification

Origin verification is a core procedure for confirming the proper application of FTA preferential tariffs, and any export or import company should clearly understand its origin documentation framework and the procedures for responding to verification.

1. Origin Verification | A Core Procedure in FTA Transactions

Origin verification refers to the series of administrative procedures for confirming whether the origin requirements set out in an agreement or domestic law are met and for taking sanctions in the event of a violation.

In a narrow sense, it refers to the procedure for confirming whether the origin determination criteria and the origin documentation are satisfied, and in a broader sense, it refers to the procedure for verifying the full range of FTA preferential requirements, including the qualifications of the transacting parties, the transport route, the application of tariff rates, and whether there has been any false labeling.


In other words, it is the process of comprehensively determining whether the application of the preferential tariff is itself lawful.

Purpose of Verification

Origin verification serves the following purposes.

• Preventing unfair trade practices

• Blocking the circumventing import of third-country goods

• Preventing tariff evasion and securing tax revenue

• Maintaining trade order among parties to an agreement

• Managing FTA implementation and securing international trust

Subjects of Verification

Origin verification is carried out with respect to the following parties.

• Domestic importers

• Domestic exporters and producers

• Certificate of origin issuing bodies

• Exporters and producers in the counterpart contracting country


In particular, not only importing companies but also exporting companies can become subjects of verification by the counterpart country, so advance preparation is needed.

2. Origin Verification | Import Verification and Export Verification

Origin verification is divided according to its subject as follows.

∙ Import verification
→ Targets goods imported into Korea to which an FTA tariff has been applied

∙ Export verification
→ The counterpart country requests verification of goods exported from Korea

Verification methods are also divided as follows.

∙ Direct verification : The customs authority of the importing country investigates the overseas exporter directly

∙ Indirect verification : The customs authority of the exporting country investigates on its behalf

∙ Mixed type : Both methods are used in parallel

Because the verification method and the response deadline differ by FTA, a response strategy tailored to each agreement is needed.

Key Checkpoints

In practice, the core issues that arise in origin verification are as follows.

Adequacy of the certificate of origin

∙ Whether the form and language prescribed by the agreement were used

∙ Whether any required entries were omitted or falsely stated


Adequacy of the issuing party

∙ Whether the certificate was issued by an exporter located in a contracting party

∙ Whether the exporter met the qualification requirements in cases of self-certification


Adequacy of the transaction structure

∙ Whether the direct transport rule was satisfied

∙ Whether the requirements for third-country intermediary transactions were met


Adequacy of the applied preferential rate

∙ Whether the goods qualify for preferential tariff treatment

∙ Whether the applied rate and period are appropriate


Whether transshipment for circumvention occurred

∙ Whether the goods merely passed through a third country

∙ Re-export without substantial transformation may constitute a violation

If even one of these elements is not satisfied, preferential tariff treatment may be denied.

3. Origin Verification | Measures After Verification

If origin verification finds that the origin requirements have not been met, a range of disadvantages may follow in stages, including denial of preferential tariff treatment, collection of back tariffs, and administrative sanctions.

Because the effects can extend to future imports of the same goods, a company may face financial and operational burdens at the same time.

Measures after verification generally proceed through the following structure: suspension of preferential tariff treatment → restriction of treatment and collection of back tariffs → stronger sanctions for repeated violations.

Suspension of Preferential Tariff Treatment

Once verification begins, customs may temporarily suspend preferential tariff treatment for identical or similar goods until the verification result is confirmed.

This measure is based on Article 17 of the Enforcement Decree of the FTA Customs Act, and it may apply not only to the goods under verification but also to identical goods imported afterward.


If verification confirms that the origin criteria are met, the suspended duties are refunded. If the criteria are not met, the suspended duties are confirmed as assessed and become a burden on the company.


In other words, a measure that affects cash liquidity begins as early as the verification stage.

Restriction of Preferential Tariff Treatment and Collection of Back Tariffs

If verification confirms any of the following grounds, preferential tariff treatment is denied, and the duties previously reduced or exempted are collected.

This is based on Articles 44 and 46 of the Enforcement Decree of the FTA Customs Act.

• The origin determination criteria were not satisfied

• Supporting origin documents were not submitted or were submitted falsely

• The partner country's verification result was not returned within the deadline

• The submission of materials was refused or access was restricted during an on-site investigation

• The obligation to retain supporting origin documents was violated

In these cases, preferential tariff treatment itself is denied, and the duties are recalculated at the general rate or the basic rate.


Collection may also take place within the five-year exclusion period running from the date preferential tariff treatment was applied, so a substantial additional payment may arise retroactively for past transactions.

Designation as a Party Restricted from Preferential Tariff Treatment

When origin-related violations are repeated, sanctions go beyond the collection of back tariffs and are strengthened against the company or exporter involved.

Under Article 37 of the FTA Customs Act, a party that has fraudulently submitted origin documentation or failed to substantiate origin in good faith two or more times within the past five years may be designated as a "party restricted from preferential tariff treatment".


In that case, preferential tariff treatment is restricted for a set period (five years) across all identical or like goods that the exporter produces or exports.


This sanction directly affects a company's price competitiveness and the continuity of its transactions, and the practical operational disadvantage is considerable.

5. Origin Verification | Response Strategy

For origin verification, "advance management" matters more than "after-the-fact response."

Advance Prevention

∙ Reviewing in advance whether the origin determination criteria are met

∙ Building processes for preparing and verifying certificates of origin

∙ Organizing a system for retaining supporting documents

∙ Reviewing the transaction structure and transport routes

After-the-Fact Response

∙ Responding to customs origin investigations and submitting written opinions

∙ Handling appeals against the collection of preferential tariffs and administrative fines

∙ Developing a strategy for responding to partner-country verification

∙ Addressing criminal liability and joint penalty provisions

Origin verification is a core risk that can limit a company's use of FTAs.

Establishing a response strategy at the early stage, upon receiving the verification notice, is what matters most.
