BYD will assemble vehicles at Sime Darby's Inokom plant in Kulim, Kedah, after scrapping a plan to build its own factory in Malaysia. The company named Inokom Corporation Sdn Bhd as its completely knocked-down (CKD) assembly partner on Thursday. Neither the models nor the production timeline have been announced.

The partnership was formalized through a memorandum of understanding signed at BYD's global headquarters in Shenzhen. Inokom, part of Sime Darby Bhd, already assembles vehicles for several global automakers. Sime Motors, another unit of the same group, distributes BYD vehicles in Malaysia. The OEM said the selection followed an assessment of local market conditions and manufacturing capabilities.

What changed since 2025?

In August 2025, BYD announced it would build its own CKD plant in Malaysia, with production expected to begin in 2026. That plan is gone. The Edge reported in September that BYD had dropped the Tanjung Malim, Perak project while staying committed to local CKD operations. The MOU with Inokom replaces a greenfield investment with contract capacity. BYD has not said how many units Inokom will build or what the arrangement costs.

The shelved project came with strings attached. According to an earlier report by The Edge, conditions included exporting up to 80% of output, with the remaining 20% sold locally at prices above 200,000 Malaysian ringgit ($48,980) per vehicle. It is unclear whether the Inokom arrangement carries similar terms. BYD did not address export obligations in its statement.

Why does local assembly matter now?

Malaysia tightened import rules on July 1. Fully built imported battery electric vehicles must now have a minimum declared CIF value of 200,000 ringgit and at least 180 kW (245 hp) of power output, according to The Edge. The threshold applies to declared import value, not retail price.

This hits BYD where it sells. Some of the brand's best-selling EVs in Malaysia retail below 200,000 ringgit. CKD assembly sidesteps the import threshold, because vehicles arrive as parts and qualify for different policy treatment.

Jacob Ma, managing director of BYD Malaysia, framed the deal as structural rather than tactical. "Local assembly is an important part of BYD's long-term commitment to Malaysia, and partnering with Sime will allow the company to draw on established automotive manufacturing capabilities," he said.

Note what that statement does not contain: no volume commitment, no investment figure, no date. An MOU is not a production contract. Tier-one announcements in Southeast Asia often precede delays, and BYD has already reversed one plant decision here within six months.

How deep does the Sime Darby relationship run?

The assembly deal deepens a partnership that already spans distribution. BYD entered Malaysia's passenger car market in December 2022 with the Atto 3, sold as the Yuan Plus in China, and Sime Motors has been its official distributor. Now the same group controls both sales and, through Inokom, production. That concentration gives Sime Darby leverage and gives BYD speed, but it also ties BYD's local manufacturing to a single partner's capacity planning.

The commercial side is moving in parallel. In August, BYD signed an MOU with Malaysian bus manufacturer Bus Cap Berhad to explore electric bus assembly and manufacturing facilities in Perak. That project remains at the exploration stage.

What to watch next: the first announcement of which BYD models Inokom will assemble, a firm production start date, and whether Malaysia's import thresholds survive the next budget cycle — each will determine whether this MOU becomes metal or paperwork.
