EU Antidumping Tariffs 2026: Real costs for terephthalic acid importers

Key data

If your company imports terephthalic acid (PTA) from South Korea or Mexico, your procurement costs have just increased. The Commission Implementing Regulation (EU) 2026/1904, published on 10 August 2026 and in force since 7 August, establishes definitive antidumping duties on these imports, consolidating the provisional measures that were already being applied. The regulation applies directly throughout the EU: it requires no national transposition.

PTA is the fundamental raw material for manufacturing PET (polyethylene terephthalate), the polymer found in beverage containers, textile fibres and packaging materials. Any company that uses PET in its production chain and sources—directly or indirectly—PTA imported from these two countries will notice the impact on its costs.

What does this regulation establish?

Regulation 2026/1904 closes the antidumping procedure opened against imports of terephthalic acid originating from South Korea and Mexico. The European Commission has concluded that these imports were being made at artificially low prices (dumping), causing harm to European producers of the same product.

The measures it establishes are:

• Definitive antidumping duties on imports of PTA originating from South Korea and Mexico.
• Definitive collection of provisional duties already applied: importers who paid the provisional duty do not recover that amount; it is consolidated.
• Direct application in all EU Member States without need for additional regulatory development.

The regulation thus consolidates a situation that already existed in the provisional phase. The novelty is that the measures cease to be temporary and become permanent (subject to periodic review under EU antidumping regulations).

Economic and operational impact

The impact is distributed asymmetrically depending on position in the value chain:

• Direct PTA importers: bear the tariff cost at the time of customs clearance. Their margin is compressed if they cannot pass the additional cost to the customer.
• PET manufacturers and processors: see their main raw material become more expensive. They must review price adjustment formulas in customer contracts.
• Packaging and packaging industry: sector intensive in PET, with typically tight margins. The impact can be significant if procurement depended on Korean or Mexican PTA.
• Textile sector (polyester fibres): PTA is also the basis for synthetic fibres. Textile companies that manufacture or use polyester may see pressure on production costs.
• European PTA producers: benefit. The measure eliminates unfair competition from low prices from South Korea and Mexico, improving their competitive position in the European market.

From an operational perspective, affected companies must update their cost models, review supply contracts with fixed price clauses and assess whether there are alternative sources of PTA not subject to these tariffs.

Who does it affect?

• European importers of terephthalic acid (PTA) originating from South Korea or Mexico.
• PET (polyethylene terephthalate) manufacturers using PTA imported from these countries.
• Companies in the packaging and packaging sector that use PET in their production.
• Companies in the textile sector that manufacture or use polyester fibres.
• CFOs and procurement managers of any company with PTA or PET in their supply chain.
• Customs advisors and logistics operators managing imports of these products.

Practical example

A Spanish PET packaging manufacturer regularly imports terephthalic acid from a South Korean supplier. Until the provisional measures came into force, that procurement was not subject to specific antidumping duties.

With Regulation 2026/1904 in force from 7 August 2026, each shipment of PTA arriving from South Korea or Mexico carries an associated definitive antidumping duty at customs. If the company has fixed-price supply contracts with its packaging customers, it cannot pass on that additional cost until the next contract renewal, which directly compresses its operating margin.

Additionally, the provisional duties it already paid during the previous phase will not be refunded: the regulation establishes their definitive collection. This means that the economic impact has already been partially realised, and the company must account for it as a firm cost.

The immediate action in this case: review whether the contract with the Korean supplier includes adjustment clauses for tariff changes, and explore PTA suppliers in countries not affected by these measures.

What should companies do now?

1. Identify the origin of PTA in your supply chain: confirm whether your current supplier supplies PTA originating from South Korea or Mexico. Customs origin is decisive, not the supplier's nationality.
2. Review current supply contracts: check whether there are price adjustment clauses for tariff changes. If not, negotiate their inclusion in the next renewal.
3. Recalculate the cost model: update the PTA procurement cost with the new definitive tariff and impact that change on your selling prices or procurement budget.
4. Evaluate alternative supply sources: analyse PTA suppliers in countries not affected by this regulation to diversify tariff risk.
5. Consult with your customs agent or foreign trade advisor: ensure that the tariff codes applied in your clearances are correct and that the definitive tariff is being correctly charged.
6. Account for provisional duties already paid: these are not refunded. Confirm with your finance team that they are correctly recorded as a definitive cost.
