Türkiye Imposes Anti-Dumping Duties up to 32.96% on Chinese Sodium Gluconate

Türkiye charges extra import duties of 22.56% to 32.96% on Chinese sodium gluconate from Oct. 14, 2026.

Türkiye’s Ministry of Trade imposed anti-dumping duties of up to 32.96% on sodium gluconate from China, starting Oct. 14, 2026.

The decision appears in Communiqué No. 2026/31, published in Türkiye’s Official Gazette on Oct. 14, 2026¹. It ends an investigation that the ministry opened in May 2025².

In short, every shipment of Chinese sodium gluconate entering Türkiye now pays an extra charge at customs. The charge is a share of the shipment’s landed value, and it depends on which Chinese company made the goods.

What is changing for sodium gluconate imports?

The ministry has put a definitive anti-dumping duty on the product. An anti-dumping duty is an extra import tax on goods sold abroad below their normal price. "Definitive" means it is the final duty, not a temporary one¹.

The communiqué says the investigation found that imports from China were dumped. It also found that these imports caused material injury, meaning real harm, to Turkish producers¹. On that basis, the Board for the Evaluation of Unfair Competition in Imports decided to act, and the Minister of Trade approved the decision¹.

Customs offices will collect the duty when the goods are released for free circulation, which means cleared for sale inside Türkiye¹. The duty applies on top of any other rules for these goods¹.

Which product does the duty cover?

The duty covers sodium gluconate under customs code 2918.16.00.00.13, made in China¹. The ministry’s final report describes the product as the sodium salt of gluconic acid³.

It is usually a white, granular, crystal-like powder. It dissolves well in water and breaks down naturally³. Its main use is to bind metals such as calcium, iron, copper and aluminium in alkaline liquids³.

Factories use it as an input for concrete, cleaning products, food and farm products, and metal processing³. The report says it is made mainly from glucose, caustic soda and enzymes³.

The communiqué adds a rule about the code. If the customs code or the product name in the Turkish tariff changes later, the duty still applies¹. The description in the investigation report is general. What counts at the border is the code and the product name in the communiqué’s table¹.

How much will importers pay on Chinese sodium gluconate?

The duty is set as a percentage of the CIF value. CIF means the price of the goods plus insurance and freight to the Turkish border¹. The rates are:

• Shandong Fuyang Bio-Tech. Co., Ltd.: 24.43%¹.
• Weifang Jianbao Biotechnology Co., Ltd.: 22.56%¹.
• All other Chinese producers: 32.96%¹.

The two named companies answered the ministry’s questionnaires on time and took part in the case³. Other Chinese makers get the highest rate, 32.96%¹.

As an example of the arithmetic, a shipment with a CIF value of $10,000 from an unnamed Chinese maker would pay $3,296 in anti-dumping duty. The same shipment from Weifang Jianbao would pay $2,256.

What did the investigation find about Chinese prices?

The ministry’s final disclosure report, dated August 2026, set out the dumping margins³. A dumping margin is how far the export price falls below the product’s normal value. The report calculated these margins as a share of the CIF value³:

• Shandong Fuyang Bio-Tech: 53.42%³.
• Weifang Jianbao Biotechnology: 52.13%³.
• All other companies: 74.96%³.

The final duties in the communiqué are lower than these margins¹. The communiqué does not explain the difference.

China did not get market-economy treatment in the case. The cooperating companies did not claim it in their questionnaire answers³. So the ministry built the normal value from Türkiye’s own costs. It used the average cost of making the product in Türkiye, plus overheads and a reasonable profit³. It then made adjustments in favour of the Chinese exporters for conditions in China³.

Why did Türkiye act against Chinese sodium gluconate?

The case began with a complaint from a Turkish producer, Sunar Mısır Entegre Tesisleri². The ministry accepted that it represents Turkish production of the product³.

Imports from China grew strongly over three years, according to the final report³:

• 6,312 tonnes in 2022.
• 8,077 tonnes in 2023.
• 9,282 tonnes in 2024.

At the same time, the average Chinese price fell. It was $912 per tonne in 2022, $652 in 2023 and $646 per tonne in 2024³. China’s share of all sodium gluconate imports rose from 93.6% in 2022 to 97% in 2024³.

Imports from other countries fell over the same years. They dropped from 432 tonnes in 2022 to 292 tonnes in 2024³. Their average price stayed much higher, at $1,032 per tonne in 2024³.

Total imports of the product reached 9,574 tonnes in 2024, worth $6.3 million³. Almost all of that came from China.

When the ministry opened the case, it said Chinese prices undercut Turkish selling prices in 2023 and 2024². It also said Chinese prices held Turkish prices down across the whole period². The opening notice listed harm to the Turkish producer’s stocks, cash flow, productivity and profits².

How did the sodium gluconate case unfold?

The ministry opened the investigation with Communiqué No. 2025/9, published in the Official Gazette on May 25, 2025². The ministry announced it on May 27, 2025, together with three other trade communiqués⁴.

The investigation looked at dumping during calendar year 2024³. For harm to Turkish industry, it looked at data from Jan. 1, 2022 to Dec. 31, 2024³.

The case followed these steps:

1. The ministry notified known Chinese producers, Turkish importers and China’s embassy in Ankara³.
2. Parties had 37 days, including postal time, to send views and answer questionnaires³.
3. Four importing companies answered the questionnaires on time³.
4. Two Chinese producers and two Chinese trading firms that sell Weifang Jianbao’s goods to Türkiye also answered³.
5. Ministry staff checked the Turkish producer’s data on site in April 2026³.
6. The ministry shared its final disclosure report with the parties in August 2026³.
7. The final duties took effect with publication on Oct. 14, 2026¹.

The two trading firms were Qingdao Reayou Chemical and Qingdao Abel Technology³. They did not get their own rate. The report says they are not related to Weifang Jianbao³.

Did importers dispute that Turkish and Chinese products are alike?

Some importers argued that Chinese and Turkish sodium gluconate differ³. They said the Turkish product has a lower acidity reading (pH) and higher heavy-metal levels³.

The Turkish producer replied that there is no single pH limit for powdered sodium gluconate³. It said test reports from accredited laboratories showed no high heavy-metal levels. The ministry found no evidence of high levels in those reports³.

The producer also submitted a study by the civil engineering department of Middle East Technical University³. That study compared Turkish, European and Chinese sodium gluconate in concrete. It found the Turkish product performed at least as well³.

Some importers that cooperated said there was no technical difference between the products³. The ministry concluded that the two are "like products", meaning they share the same physical features and main uses³.

What other charges already apply to sodium gluconate?

The anti-dumping duty adds to charges that already exist. The ministry’s report lists the regular import duty for this code under Türkiye’s 2026 import rules³. Goods from China fall in the "other countries" column, at 6.5% customs duty³. Value added tax (VAT) on the product is 20%³.

The report also notes a 5% additional customs duty on imports of the product³. This rests on Decision No. 3351 of Dec. 31, 2020, as amended by Decision No. 9392³.

There is a further check at the border. Imports valued below $1.5 per kilogram need a surveillance document, a special import record³. This rule applies to goods from all countries³. It comes from a surveillance communiqué published on July 31, 2025³.

How long will the duties last?

The duties stay in force for 5 years from Oct. 14, 2026¹. After that, they end automatically, unless a review is opened¹.

If the ministry opens an expiry review before the 5 years end, the duties continue until the review is finished¹. The Minister of Trade is responsible for carrying out the communiqué¹.

For buyers in Türkiye, the duty raises the cost of the cheapest Chinese supply. Concrete, cleaning-product and food makers that rely on Chinese sodium gluconate will see their input costs rise. Chinese makers other than the two named companies face the steepest charge.

Key points on Türkiye’s sodium gluconate duty

The table below sums up the main facts of the decision.

From Oct. 14, 2026, every shipment of Chinese sodium gluconate cleared in Türkiye pays between 22.56% and 32.96% extra. The duties run for 5 years unless an expiry review keeps them in place¹.
