VinFast (VFS) Signs Automotive Component Supply Deal with HS Hyosung

Overview

VinFast Vietnam and HS Hyosung signed a cooperation agreement covering the supply of automotive components, announced on 29 September at the groundbreaking of HS Hyosung’s USD 100 million BCF fiber and carpet plant in Quang Nam. The agreement links Vietnam’s largest domestic automaker to a Korean industrial group that holds the world’s leading position in PET tire cord, a reinforcement material used inside tires. The disclosure did not specify component types, contract value, volumes or duration.

Key Facts

• HS Hyosung and VinFast Vietnam signed the automotive component supply cooperation on 29 September, at the groundbreaking ceremony in Quang Nam.
• The host project is a BCF fiber and carpet plant in Tam Thang Expanded Industrial Park, roughly 11 hectares, with registered capital of VND 2,606.1 billion, equivalent to about USD 100 million.
• The investment certificate was first issued on 28 July 2026.
• Phase 1 carries USD 80 million of investment, targeting operation in Q4 2027 with capacity of about 10,800 tonnes of BCF fiber, 3.8 million sqm of automotive carpet and 4 million sqm of other carpet per year.
• Phase 2 adds USD 20 million, scheduled from Q2 2029, adding about 6,000 tonnes of BCF fiber annually.
• HS Hyosung Advanced Materials holds the world’s number one share in PET tire cord, used in roughly half of all passenger car tires globally; the group also produces seatbelt, airbag, steel cord, aramid and carbon fiber materials.
• HS Hyosung has invested in Vietnam since 2007, with cumulative disclosed investment of about USD 4.6 billion by 2025, more than 10,000 employees and annual revenue of about USD 3.5 billion.
• HS Hyosung Quang Nam, established in 2018, had already invested over USD 450 million in the area before this project, focused on tire cord, technical fiber and automotive airbag materials.

What Happened

At the ceremony organised by the Chu Lai Open Economic Zone Authority together with HS Hyosung Quang Nam Company Limited, the two sides signed a cooperation agreement on automotive component supply. The event marked the start of construction of the BCF fiber and carpet plant, a two-phase project producing BCF yarn and carpets for automotive and other applications. The published information did not state which components fall under the cooperation, nor the contract value, output volumes or term.

HS Hyosung is a Korean industrial group formed after the restructuring of Hyosung Group in July 2024, inheriting long-established businesses in industrial materials and automotive materials. Phan Thai Binh, Vice Chairman of the Da Nang City People’s Committee, said at the event that the city would continue to support HS Hyosung, VinFast and other companies in the value chain investing and operating in the city over the long term.

Market Context

VinFast Auto trades on the Nasdaq under the ticker VFS, with a close of 9,900 in the reference price context dated 29 September 2026. The company sits in the automotive sector, where localisation of parts supply is a recurring theme for Vietnamese assemblers seeking to reduce import dependence and exposure to freight and tariff costs. HS Hyosung’s expanding footprint in Quang Nam, spanning tire cord, airbag material and now carpet and BCF fiber, places a global materials supplier inside Vietnam’s emerging automotive cluster.

Strategic Significance

The agreement matters less for its immediate commercial value, which was not disclosed, than for what it signals about VinFast’s sourcing architecture. VinFast has consistently pursued vertical integration and local content to defend margins against currency and logistics costs. Tying into HS Hyosung, whose Advanced Materials unit supplies roughly half of global passenger car tires with PET tire cord, gives VinFast access to a supplier with scale in reinforcement, safety and interior materials. For HS Hyosung, a VinFast supply relationship anchors demand for its Quang Nam output and strengthens the case for further capacity in the region.

What to Watch

• Any VinFast or HS Hyosung disclosure specifying component categories, contract value, volumes or duration.
• Phase 1 commissioning progress toward the stated Q4 2027 target and whether automotive carpet output is directed to VinFast.
• VinFast quarterly production and localisation disclosures indicating rising domestic content.
• Further HS Hyosung investment announcements in Quang Nam or Da Nang beyond the USD 450 million already committed.
• VFS share price reaction and any related-party or supply-chain filings.
