ASL LAW's comprehensive timeline of Mexico's SW 2025 IN anti-dumping investigation on Vietnamese steel wire ropes.

Mexico initiates an anti-dumping investigation on steel wire ropes imported from Vietnam (SW 2025 IN)

On September 30, 2025, the Ministry of Economy of Mexico announced the initiation of an anti-dumping investigation concerning certain steel wire ropes imported from Malaysia and Vietnam.

Case information

The product under investigation is steel wire rope — a collection of steel strands twisted around a core. The diameter of the investigated products ranges from 3.18 mm to 79.38 mm (equivalent to 1/8 inch to 3 1/8 inch).

The HS codes subject to investigation include 7312.10.01, 7312.10.05, 7312.10.07, and 7312.10.99.

The petitioner in this case is Deacero, S.A.P.I. de C.V.

The period of investigation (POI) for dumping practices is from January 1, 2024, to December 31, 2024.

The injury investigation period is from January 1, 2022, to December 31, 2024.

Mexico is expected to use domestic sales transactions in the country under investigation as the reference for determining the normal value of the exported products.

According to the initiation notice, the total import value of steel wire ropes into Mexico increased by 24% during 2022–2024. The import growth was 14% in 2023 and 9% in 2024. Malaysia currently accounts for the largest share (21%), followed by Vietnam (17%), the United States (12%), India (10.4%), South Korea (10%), Thailand (9%), and Germany (6%).

Information submission requirements

The deadline for registration as an interested party is 23 working days, starting five days after the publication date of the initiation notice (i.e., from September 30, 2025).

The Ministry of Economy of Mexico has distributed investigation questionnaires to relevant Vietnamese enterprises to collect data for the investigation process. Recipients of the questionnaires may include producers, exporters, or entities involved in the supply chain of the investigated products.

The deadline for submitting questionnaire responses is before November 7, 2025 (Mexico time).

General recommendations for enterprises

Vietnamese exporters of steel wire ropes should closely monitor the progress of the case and thoroughly review Mexico’s anti-dumping investigation procedures to develop an appropriate response strategy.

Providing complete, accurate, and timely information — and cooperating actively throughout the investigation — is critical to minimizing the risk of being subject to high duties or unfavorable measures.

Where enterprises are uncertain about procedures, price calculation methodologies, or evidence presentation, they are encouraged to seek assistance from experienced legal or trade remedy consultants to ensure full compliance with the technical and legal requirements of the Mexican investigating authority.

To protect their legitimate interests, manufacturers and exporters should familiarize themselves with the procedure and actively contact Vietnam Antidumping Law Firm specializing in anti-dumping and trade remedy for timely assistance.
