In the specialty chemicals industry, competitive advantage is built on three fundamental pillars: resource security, technological expertise, and supply chain integration. For Brother Technology Co., Ltd., the acquisition of BROTHER CISA (PTY) LTD (CISA) in South Africa in 2020 was far more than an overseas investment—it was a long-term strategic move designed to strengthen upstream capabilities and reinforce the company's global industrial foundation.
By integrating a century-old chromium chemicals manufacturer with German technological heritage, Brother Technology successfully completed its chromium chemicals value chain, achieving vertical integration and significantly enhancing its competitiveness in the global specialty chemicals market.
Located in Newcastle, South Africa, BROTHER CISA operates on approximately 500 mu (about 33 hectares) of industrial land and carries more than 100 years of experience in chromium chemicals manufacturing.
Originally part of the global specialty chemicals company Lanxess, CISA inherited German manufacturing standards, mature production technologies, rigorous quality management systems, and comprehensive regulatory qualifications.
Its primary products include:
These products serve as essential raw materials for leather processing, pharmaceutical catalysts, pigments, and, most importantly, the production of Vitamin K3, one of Brother Technology's flagship products.
Chromium chemicals remain one of the most highly regulated sectors within the specialty chemical industry due to stringent environmental requirements, demanding production technologies, and concentrated resource distribution. Since South Africa possesses the majority of the world's chromite reserves, compliant large-scale chromium chemical assets are exceptionally scarce.
Before the acquisition, CISA had already established itself as one of the industry's most valuable chromium chemical production bases, combining abundant mineral resources, German engineering excellence, and decades of operational expertise.
Prior to the acquisition, Brother Technology had already become a global leader in Vitamin K3 and an important supplier of leather chemicals. However, the company still faced two significant industry-wide challenges:
Sodium dichromate is the key raw material for producing both Vitamin K3 and chromium tanning agents. Relying on external suppliers exposed the company to volatile raw material prices, supply instability, and international logistics risks.
China's increasingly stringent environmental regulations made approvals for new chromium chemical production capacity extremely difficult. This restricted opportunities for upstream expansion while leaving manufacturers vulnerable to fluctuating supplier pricing.
To address these structural challenges, Brother Technology acquired 100% of CISA from Lanxess for approximately RMB 660 million.
Rather than pursuing short-term production expansion, the acquisition fundamentally transformed the company's supply chain by internalizing a critical upstream resource and improving long-term operational certainty.
Unlike many international acquisitions that focus solely on expanding production capacity, Brother Technology's acquisition of CISA established a fully integrated industrial chain linking chromium chemicals with specialty chemicals and Vitamin K3 production.
South Africa possesses some of the world's richest chromite resources, allowing CISA to source raw materials locally while significantly reducing transportation expenses.
Additional cost advantages include:
These advantages substantially strengthen Brother Technology's upstream supply security while reducing overall production costs.
CISA inherited advanced chromium chemical manufacturing technologies developed under Lanxess, particularly in:
Higher-purity chromium chemicals enable applications in pharmaceuticals, premium leather processing, and other high-value specialty chemical markets.
The acquisition also enhanced Brother Technology's integrated production model. Through its proprietary co-production technology, the company can produce approximately 15 tons of chromium tanning agents alongside every 1 ton of Vitamin K3, maximizing resource utilization while reducing unit production costs.
This integrated manufacturing capability creates a significant technological barrier that is difficult for competitors to replicate.
The acquisition delivers benefits across both domestic and international markets.
For Brother Technology's Chinese manufacturing facilities, CISA provides a stable internal supply of sodium dichromate, ensuring reliable production of Vitamin K3 and leather chemicals while minimizing exposure to commodity price volatility.
Internationally, CISA's South African production base serves customers throughout:
Its strategic location also helps mitigate trade barriers and strengthens Brother Technology's global sales network.
Today, the company has become China's largest producer of chromium tanning agents and the world's third-largest producer, further solidifying its international market position.
Following several years of successful integration, Brother Technology's specialty chemicals business has become one of the company's major revenue contributors, generating RMB 1.243 billion in revenue in 2025, demonstrating the long-term value created by this strategic acquisition.
As more Chinese specialty chemical companies expand internationally, many focus primarily on contract manufacturing or relocating production capacity overseas.
Brother Technology has chosen a different path.
Instead of simply adding overseas facilities, the company acquired a high-quality strategic asset with over a century of manufacturing experience, advanced technologies, valuable mineral resources, and internationally recognized operational systems.
The acquisition transformed Brother Technology from a company dependent on external chromium chemical suppliers into one controlling critical upstream resources, operating an integrated production chain, and serving customers worldwide.
The resulting improvements in supply security, production efficiency, technological capability, and cost competitiveness have become essential strengths that support sustainable growth throughout industry cycles.
In the chemical industry, lasting success is never achieved through shortcuts. It is built through continuous investment in technology, supply chain integration, and industrial capabilities.
With South Africa as a strategic foundation and global markets as its destination, Brother Technology will continue strengthening the operation of its overseas assets, expanding its chromium chemicals business, and advancing its position as a leading global specialty chemicals manufacturer.
