Turkey's Anti-Dumping Duties on Chinese Polymers: What Every Importer Needs to Know

Turkey imports roughly 6-7 million metric tons of polymer resin annually, making it one of the largest plastics processing hubs between Europe and Asia. China is a significant and growing source of that supply — particularly for polyethylene, polypropylene, and PVC — driven by structural feedstock cost advantages that Chinese CTO (coal-to-olefin) and PDH (propane dehydrogenation) producers hold over naphtha-based competitors.

But the FOB price advantage that draws Turkish buyers to Chinese polymer is not the number that matters. The number that matters is landed cost at Mersin, Ambarlı, or Gemlik — and between the FOB quote and the customs-cleared cost sits a duty stack that can add 9.5-24.5% to the CIF value in non-recoverable duties alone. That stack includes both standard customs duties and anti-dumping duties, and for many mid-tier importers, it is not fully understood.

This guide breaks down Turkey's anti-dumping regime as it applies to Chinese-origin PE, PP, and PVC — the legal framework, current duty rates, the full cost stack, company-specific versus residual rates, review timelines, and mitigation mechanisms. It is the first in a five-part series on navigating trade defense costs in Turkish polymer procurement.

This is not legal advice. It is procurement intelligence based on published trade defense decisions. For binding rate determinations, consult the relevant Resmi Gazete communiques and your customs broker.

Anti-dumping duties are additional levies imposed on imports sold below "normal value" — the price in the exporter's home market, or a constructed value based on production costs plus reasonable profit. They are not tariffs in the conventional sense. They are a trade defense instrument, authorized under WTO rules and applied when dumped imports cause material injury to domestic industry.

In Turkey, the legal basis is Law No. 3577 (İthalatta Haksız Rekabetin Önlenmesi Hakkında Kanun — the Law on the Prevention of Unfair Competition in Imports), supplemented by implementing regulations. The investigating and enforcing authority is the Damping ve Sübvansiyon Araştırma Dairesi (Anti-Dumping and Subsidies Investigation Division) within the İthalat Genel Müdürlüğü (General Directorate of Imports) of the Ticaret Bakanlığı (Ministry of Trade).

The process works as follows:

1. Petition. A domestic producer — in Turkey's polymer context, primarily Petkim (SOCAR Turkey) — files a petition demonstrating that imported goods are being sold below normal value and that this is causing material injury.
2. Investigation. The Ministry initiates a formal investigation, lasting up to 12 months (extendable to 18). During this period, the Ministry examines export prices, constructs normal value, calculates the dumping margin, and assesses injury and causality.
3. Provisional measures. After a minimum of 60 days from initiation, the Ministry may impose provisional anti-dumping duties if preliminary findings support dumping and injury. Provisional measures can remain in place for up to four months (extendable to nine in certain cases).
4. Final determination. Published as a communique (tebliğ) in the Resmi Gazete (Official Gazette, available at resmigazete.gov.tr). This sets definitive duty rates for a period of up to five years.
5. Sunset review. Before the five-year period expires, domestic producers can request a review. If the review finds that removing the duty would likely lead to recurrence of dumping and injury, the measures are extended for another five years.

The critical point for importers: anti-dumping duty is a separate charge on top of the standard MFN customs duty. Your total duty burden is MFN + AD, both calculated on the CIF value.

As of early 2026, Turkey maintains anti-dumping measures on Chinese-origin polyethylene and polypropylene. PVC has been subject to investigation proceedings, and importers should monitor developments closely. The table below summarizes the current landscape.

Important note on rates: Anti-dumping duty rates vary by specific HS subheading, by individual Chinese exporter (cooperating vs. non-cooperating), and by grade type. The ranges below represent approximate spans across subheadings and exporters as published in the relevant Resmi Gazete communiques. Confirm the exact rate applicable to your specific product and supplier with your customs broker before placing an order.

Polyethylene (PE) — HS 3901

PE anti-dumping measures were established through investigations in the early 2020s. The wide rate range (approximately 3-18%) reflects the spread between company-specific rates for cooperating Chinese exporters at the low end and the residual rate applied to non-cooperating or new exporters at the high end.

Polypropylene (PP) — HS 3902

PP duties tend to be higher than PE duties. Petkim maintains significant PP production capacity domestically, and the injury case is correspondingly stronger. High-volume grades commonly imported from China — including raffia grade T30S and copolymer grades such as EPS30R — are among the most frequently affected items at the customs declaration stage.

PVC (Suspension Grade) — HS 3904

As of early 2026, PVC anti-dumping proceedings are ongoing. No definitive duties have been imposed yet, but provisional measures remain a possibility. PVC importers should monitor Resmi Gazete announcements and Ticaret Bakanlığı press releases closely. If the investigation concludes affirmatively, PVC duty rates would likely fall within a range comparable to PE and PP.

Understanding the complete cost structure is essential for accurate procurement decisions. Here is the full duty stack for a Chinese-origin polymer import into Turkey.

Cost Components

Effective Cash Burden

The MFN duty and anti-dumping duty represent the non-recoverable cost burden for a domestic resale or processing operation. KDV is recoverable for VAT-registered businesses through the standard offset mechanism, so it affects cash flow but not final cost.

Effective non-recoverable duty = MFN (~6.5%) + AD (3-18%) = approximately 9.5-24.5% of CIF value.

For the highest-rate scenarios — a non-cooperating Chinese exporter shipping PE or PP at residual rates — the combined MFN + AD burden can approach 24-25% of CIF value. At the lower end, a cooperating Chinese PE exporter may face a combined burden of approximately 9.5-10%.

Worked Example: PP Homopolymer, CIF Mersin

In this scenario, Chinese PP starts $130/MT cheaper on CIF but ends up only ~$23/MT cheaper after duties. The anti-dumping duty erodes most of the headline price advantage. Whether the remaining gap justifies the sourcing decision depends on quality requirements, payment terms, delivery lead time, and the buyer's risk tolerance.

The math changes when oil prices are high. CTO/PDH-based Chinese producers can maintain FOB discounts of $100-200/MT over naphtha-based Korean, Saudi, or European producers when crude is elevated. At those spreads, the anti-dumping duty narrows but does not eliminate the Chinese cost advantage.

The takeaway: Anti-dumping duties do not make Chinese polymer uncompetitive in Turkey. They change the threshold at which it becomes competitive, and that threshold moves with feedstock economics and freight markets.

This distinction has direct commercial consequences, yet many importers are not aware of it.

During an investigation, the Ministry requests cooperation from known Chinese exporters — submission of cost data, production records, domestic sales prices, and export transaction data. Cooperating exporters receive an individually calculated duty rate based on their specific dumping margin. Non-cooperating exporters receive the residual rate — typically the highest rate applied.

What This Means in Practice

• If you buy from a cooperating Chinese exporter with an individually assigned rate, you may pay a significantly lower anti-dumping duty — potentially as low as 3-5% for some PE exporters, versus the residual rate at the high end of the range (up to 18%).
• If you buy from a non-cooperating exporter, or from a Chinese producer not covered in the original investigation (a new market entrant, for example), the residual rate applies by default.
• The difference can be $50-100/MT in duty cost on a single shipment, depending on the product and CIF value.

How to Verify

Your customs broker can check the applicable rate for a given Chinese exporter by referencing the specific communique published in the Resmi Gazete. The communique lists cooperating exporters by name alongside their individual duty rates, and separately states the residual rate applicable to all others.

When evaluating Chinese suppliers, ask explicitly: "Was your company a cooperating exporter in Turkey's anti-dumping investigation on [product]? What is your individually assigned duty rate?" Suppliers with favorable individual rates will typically know this and may cite it as a competitive advantage.

New Shipper Review

Chinese producers that did not export to Turkey during the original investigation period can apply for a new shipper review (yeni ihracatçı gözden geçirmesi) through the Ticaret Bakanlığı. If the review finds that the new shipper's pricing does not involve dumping (or involves a lower margin), an individual rate will be assigned — ensuring new market entrants are not permanently penalized by the residual rate.

Institutional Framework

Key Administrative Facts

• Duration: Definitive anti-dumping duties are imposed for up to five years from the date of the communique.
• Sunset reviews: Before the five-year period expires, domestic industry can petition for a review. If the Ministry finds that removal of the duty would likely lead to continuation or recurrence of dumping and injury, the measures are extended for another five years.
• Provisional measures: Can be imposed after a minimum of 60 days from the initiation of an investigation. This means that even before a final determination, importers may face provisional duties.
• Retroactive application: In certain cases, definitive duties can be applied retroactively to imports that entered during the provisional duty period.
• Scope of Turkey's AD activity: Turkey is one of the most active users of anti-dumping measures globally. As of 2023-2024, Turkey had over 200 anti-dumping measures in force across all product categories — placing it among the top five users worldwide by measure count.

Monitoring Changes

Importers should establish a routine for monitoring Resmi Gazete for new communiques affecting HS chapters 39 (plastics). The Ministry of Trade website (ticaret.gov.tr) also publishes investigation notices and preliminary findings. PAGEV (Türkiye Plastik Sanayicileri Araştırma, Geliştirme ve Eğitim Vakfı — the Turkish Plastics Industry Foundation) regularly reports on trade defense developments affecting the sector.

Anti-dumping measures are not permanent. They operate on five-year cycles, and the review calendar directly affects procurement planning.

PE (Polyethylene)

The current measures on Chinese-origin PE have been subject to sunset review proceedings. As of early 2026, the measures are expected to remain in force or be extended. The domestic industry — led by Petkim — has consistently advocated for continuation. Turkish PE imports from China have remained substantial despite the duties, which strengthens the domestic industry's case that removal would lead to a surge in dumped imports.

Practical implication: PE importers should plan on the assumption that anti-dumping duties will remain in place through at least 2027-2028. Budget accordingly.

PP (Polypropylene)

PP measures are on a similar trajectory. Renewal proceedings have been initiated, and industry advocacy (particularly from PAGEV) supports extension. Given Petkim's significant domestic PP production capacity, the political and economic case for maintaining protection is strong.

Practical implication: PP duties are unlikely to be removed in the near term. If anything, the trend is toward sustained or marginally higher rates at the next review.

PVC

The PVC situation is more fluid. Investigation proceedings were ongoing as of early 2026, and no definitive duties had been imposed. The outcome will depend on the Ministry's findings regarding dumping margins, injury, and causality. If definitive duties are imposed, they would likely take effect in the second half of 2026 or early 2027.

Practical implication: PVC importers should prepare contingency pricing models that include a potential anti-dumping duty of 10-20% on Chinese-origin suspension-grade PVC. If you are currently sourcing PVC heavily from China, begin evaluating alternative origins now — not after the communique is published.

Turkey's trade defense activity on polymers is not limited to China. Understanding the broader landscape helps importers assess where real cost advantages lie.

Other Origins Under AD Measures or Investigation

Origins With No AD Duties (Structural Advantages)

The EU advantage is structural. European-origin polymer enters Turkey duty-free under the Customs Union — a SABIC or BASF grade produced in an EU facility faces zero duty, while the identical specification from China faces 9.5-24.5%. However, EU-origin polymer is typically priced higher at FOB/FCA level, reflecting higher feedstock and energy costs. Whether the duty advantage offsets the higher base price depends on the specific grade and market conditions.

Several mechanisms can reduce or eliminate the anti-dumping duty burden. Each has specific requirements and limitations. The summaries below are introductory — detailed treatment of each mechanism will follow in subsequent articles in this series.

1. Inward Processing Regime (Dahilde İşleme Rejimi — DİR)

The most powerful mitigation tool available. Under DİR, raw materials imported for processing into finished goods that will be re-exported are exempt from both MFN customs duty and anti-dumping duty.

• Who qualifies: Manufacturers and converters who process imported polymer into finished or semi-finished products for export (plastic packaging, automotive components, white goods parts, pipe, film, etc.).
• Authorization: Obtained from Ticaret Bakanlığı. Requires a commitment to re-export processed goods within a specified timeframe.
• Key constraint: The imported material must be processed and re-exported. If the finished goods are sold domestically instead, the suspended duties become payable with interest.
• Scale of impact: For a qualifying converter, DİR can eliminate $115-190/MT in duty costs, making Chinese polymer fully competitive with any alternative origin.

Detailed guide: See Article 3 in this series — "How Turkish Converters Import Chinese Polymer Duty-Free: The Inward Processing Regime Explained."

2. HS Classification Optimization

Not all polymer grades within a given HS chapter attract anti-dumping duties. The measures are imposed on specific subheadings, and certain specialty grades, compounds, or modified polymers may fall outside the scope of the applicable communique.

• Example: A masterbatch or compounded grade classified under a different HS subheading than the base resin may not be covered by the AD measure on the base resin.
• Caution: Misclassification — whether intentional or accidental — carries significant penalties. Any classification strategy must be validated by your customs broker and supported by laboratory analysis if required by customs authorities.

3. Company-Specific Sourcing

As discussed above, buying from a Chinese exporter with an individually assigned (lower) duty rate can reduce the AD burden by 5-10 percentage points compared to the residual rate. This is the simplest mitigation available and requires no regulatory application — only knowledge of which suppliers have favorable rates.

4. Origin Diversification

Anti-dumping duties are origin-specific. The same polymer grade sourced from a country not subject to AD measures enters at the MFN rate only (~6.5%). For some grades, the total cost from an alternative origin (Korea, Saudi Arabia, UAE, or EU) may be lower than from China after AD duties are applied — even if the FOB price is higher.

The decision is grade-specific and market-condition-dependent. It requires comparing total landed costs across origins on a regular basis — not a one-time analysis, but an ongoing discipline.

Detailed guide: See Article 2 in this series — "What Chinese PE and PP Actually Costs in Turkey: A Landed Cost Breakdown."

Anti-dumping duties on Chinese polymers are a structural feature of the Turkish market, not a temporary disruption. They have been in place for years, they are likely to be renewed, and they may expand to cover PVC if the current investigation concludes affirmatively. Any procurement strategy that ignores them is incomplete.

But duties are not a binary signal to avoid Chinese polymer. They are a cost variable that shifts the competitive threshold. Three principles should guide procurement decisions:

First, know your actual duty rate. The difference between a 3% company-specific rate and an 18% residual rate on PE is roughly $150/MT at current CIF levels. That difference is larger than most freight rate variations and most negotiated discounts. Supplier selection — specifically, selecting Chinese exporters with individually assigned lower rates — is one of the highest-value procurement actions available.

Second, calculate total landed cost, not FOB price. FOB is the starting point, not the answer. CIF + MFN duty + anti-dumping duty + port charges + inland logistics = the number your P&L actually sees. This calculation must be done per grade, per origin, per supplier — and it must be updated frequently, because the variables (FOB price, freight rate, FX rate) change weekly.

Third, the math changes with the market. When oil prices are high, CTO/PDH-based Chinese producers can sustain FOB discounts of $100-200/MT over naphtha-based competitors. At those spreads, Chinese polymer remains the lowest-cost option even after a 15% anti-dumping duty. When oil prices are low and the naphtha advantage narrows, alternative origins become more competitive. The optimal sourcing mix is dynamic, not static.

Turkish polymer importers who track these variables daily — who know whether today's Chinese FOB price, after freight, duties, and charges, still beats the Korean or Saudi alternative — have a structural information advantage over those who rely on quarterly reviews or gut feel.
