In the context of the Covid-19 pandemic, to facilitate the relevant parties’ preparation of sufficient information and data as well as to clarify the impact of dumping on the operation of the domestic manufacturing industry, including downstream manufacturing industries, the Ministry of Industry and Trade has extended the time limit for investigating the case to October 6, 2021.

The official investigation results showed a sudden increase in the amount of goods imported from China, India, Indonesia, and Malaysia. In particular, in the context of Covid-19, imports of polyester filament yarn in the first 6 months of 2021 reached nearly 258,000 tons, up 37% over the same period in 2020. Dumping imported goods was the main cause of significant damage to the domestic industry.

Using official anti-dumping measures will help level the playing field for local industries, improve their control over raw materials, and boost the value and competitiveness of Vietnamese products and businesses in the global market. In addition, Vietnam has joined many Free Trade Agreements (FTAs), creating favorable conditions for many economic sectors, including textiles, to expand export markets. However, to enjoy tariff preferences, the domestic manufacturing industry must meet strict rules of origin according to each FTA. Therefore, the textile industry can take advantage of the benefits from FTAs by increasing its initiative in raw material production and meeting origin requirements.

In the coming time, the Ministry of Industry and Trade will continue to coordinate with relevant ministries and related parties to monitor the impact of trade remedies, production situations, supply and demand, prices, etc. to ensure a fair competitive environment with equality and convenience for the manufacturing industry in accordance with regulations.

Significance of the review

Periodic reviews play a vital role in the implementation of trade remedy measures, aiming to:
• Ensure the reasonableness and transparency of AD duties, preventing measures from being maintained at levels higher or lower than necessary.
• Provide opportunities for exporters to demonstrate changes in production conditions, costs, or prices, which could result in lower duties.
• Protect the domestic industry from potential injury caused by dumped imports while maintaining a fair competitive environment.

Recommendations for enterprises

During this extended period, relevant parties—including producers, exporters, importers, and industry associations—should:
• Proactively provide information and supporting data on production, export, or import activities related to polyester staple fibers.
• Closely monitor the investigation process and official announcements from the Ministry of Industry and Trade to respond appropriately.
• Prepare long-term strategies, including market and product diversification, and explore opportunities to leverage review mechanisms to mitigate risks.
