Vietnam anti-dumping actions on Chinese steel expanded on July 27 through two separate Ministry of Industry and Trade decisions. Although both cases concern Chinese-origin steel, their legal and commercial effects are different.

The prestressed bar case is a new investigation. By contrast, the hot-rolled steel case reviews a duty that Vietnam already applies under Decision No. 1959/QĐ-BCT.

What took effect on 27 July 2026?

Which prestressed steel products are under investigation?

AD24 covers silicon-manganese alloy steel bars supplied as straight bars, rods or coils. Products may have a smooth circular surface or spiral ribs and measure 7.1–12.6 mm in diameter.

The relevant Vietnamese HS codes are 7227.20.00, 7228.20.11, 7228.20.19 and 7229.20.00. The dumping period runs from July 2025 through June 2026, while the injury review covers four years from July 2022.

What duty or restriction applies to prestressed bars?

The investigation does not create an immediate anti-dumping tax. The Vietnamese petitioners proposed a dumping margin of 23.06%, although that figure is only an allegation at this stage.

MOIT may impose a provisional measure after its preliminary analysis. Therefore, contracts for future Vietnamese customs clearance should include a duty-change clause and clear responsibility for any additional tax.

What does the HRC interim review cover?

The review covers products already subject to Vietnam’s definitive HRC measure. These include carbon and alloy hot-rolled flat products across 27 Vietnamese tariff lines in Chapters 72.

Importantly, the review was requested by Baosteel Group and focuses on that group’s dumping margin and applicable rate. It is not a general reopening for every Chinese producer.

Do the current HRC duties still apply?

Yes. Vietnam’s existing definitive anti-dumping schedule remains the operative basis unless MOIT publishes a revised decision. Current company-specific rates range from 23.10% to 27.83%.

The review is expected to finish within six months, although authorities may extend it by up to three months. Until then, importers should calculate landed cost with the current exporter-specific rate.

How are Chinese exporters affected?

Prestressed bar exporters should register as interested parties, answer questionnaires on time and preserve complete cost, sales and origin records. Non-cooperation may allow investigators to rely on adverse facts.

Baosteel Group has an opportunity to seek a lower HRC rate through verified data. Other Chinese HRC exporters should not assume that the review will automatically change their duties.

The two cases also reinforce the wider pressure described in TISCO’s analysis of anti-dumping measures affecting Chinese steel exports .

What should Vietnamese and overseas buyers do?

Vietnamese importers should verify the producer, exporter, origin and exact HS classification before shipment. A trader’s name alone may not establish the correct company-specific duty.

Buyers outside Vietnam may see Chinese material redirected toward other Asian, Middle Eastern or African markets. That shift could create competitive offers, although origin documents and destination trade remedies still require careful review.
