China-Korea FTA Tariff Reduction Schedule 2026 Update

Why the Bilateral Route Still Matters

RCEP has been in force for China since 1 January 2022, and it covers Korea. It would be reasonable to assume the China–Korea FTA has become redundant.

It has not. The two agreements have different staging schedules, different origin rules and different cumulation scope. For a given product, one may be clearly better than the other, and which one it is changes from line to line.

The 2026 Step

The China–Korea FTA entered into force on 20 December 2015. Its reduction schedule runs over roughly twenty years, with annual steps.

The 2026 revision is another step in that sequence. Industrial goods, consumer goods, chemicals and textiles all continue their descent.

Two points matter for exporters.

The step is line-specific

Lines within the same chapter do not move at the same pace. A chapter-level assumption is unreliable; only the ten-digit line in the schedule tells you what applies this year.

The rate that matters is the import-side rate

A Chinese exporter shipping to Korea is affected by Korea’s schedule, not China’s. Checking the Chinese schedule for a shipment to Busan answers the wrong question.

Comparing the Two Routes

Rates

For some lines the China–Korea FTA rate is lower. For others, RCEP is lower. There is no general rule.

Origin rules

The product-specific rules differ. A product that satisfies one agreement’s rule may fail the other’s.

Cumulation

This is the decisive difference for many products.

Under the China–Korea FTA, cumulation is bilateral. Only Chinese and Korean originating materials count.

Under RCEP, cumulation spans fifteen members. Japanese, Australian, New Zealand and ASEAN materials also count.

For a Chinese manufacturer using Japanese components, the RCEP route is often the only one that clears the regional value content threshold.

Evidence burden

The bilateral route requires proof only for Chinese and Korean material. The RCEP route requires proof for material from all fifteen members.

That is a broader evidence base to maintain. But if the company already sources across Asia, that evidence system is needed anyway.

An Illustration

A manufacturer exports industrial pumps to Korea.

Inputs: motors from Japan at twenty-five percent of cost, seals from Germany at ten percent, pump bodies made in China at forty percent, other materials and labour at twenty-five percent.

Under the bilateral agreement

The Japanese motors and German seals are both non-originating, totalling thirty-five percent. If the product-specific rule requires a regional value content of sixty percent, the product clears only narrowly at sixty-five.

Under RCEP

The Japanese motors become originating. Only the German seals remain non-originating, at ten percent. Regional value content rises to ninety.

Both routes pass today. But the bilateral route has almost no margin. A modest increase in motor prices or a currency shift could push it below the threshold, while the RCEP route continues to clear comfortably.

Practical Steps

Classify inputs by origin

Not a financial classification but an origin classification. Each input marked as originating in an RCEP member or not.

Obtain origin evidence

Originating status for member-state material requires proof, in the form of a supplier origin declaration or certificate.

Run both determinations

For each product, calculate origin under both agreements separately. The conclusions may differ, and they must be documented independently.

Review annually

Rates move, costs move, suppliers change. A conclusion reached last year may be wrong this year.

Common Mistakes

Blending the two agreements

A single shipment takes one route. Rules from the China–Korea FTA cannot be used to determine RCEP origin, or the reverse.

Using one determination for both

The same product may qualify under one agreement and fail under the other. Separate analyses are required.

Checking only the export schedule

The applicable rate is the one in force in the destination market.

An Assessment

For exporters to Korea, the question is now one of choice rather than compliance.

The compliance floor is the same either way: the product must genuinely satisfy the origin rules of whichever agreement is claimed.

The room for choice lies in which agreement is more favourable and which evidence base is easier to sustain.

That choice should be revisited at least once a year, because rates change and cost structures change with them.
