Completion of Plant 2. Chlorotoluene: Plant 2: Production of para‑chlorotoluene/ortho‑chlorotoluene from toluene began. The completion of the two 50 m tall distillation towers, standing tall and proud, became a symbol of our company and marked the first step toward expanding chlorotoluene sales worldwide.

Capital increased to 600 million yen.

Completion of Plant 3. Para‑chlorobenzotricloride: Plant 3: Production of para‑chlorobenzotricloride began.

Opening of Tokyo office. Initiated research into new products for the future.

Completion of Plant 4. Acid chloride: Plant 4: Production of ortho‑toluyl acid chloride began as a raw material for the pesticide bactericide Bascat of parent company Kumiai Chemical Industries Co., Ltd. Currently, it serves as a production facility for other acid chlorides.

Completion of Plant 5. Chlorobenzaldehyde: Plant 5: Production of para‑chlorobenzaldehyde/ortho‑chlorobenzaldehyde began as a hydrolysis facility to establish a supply system for the world market, amid expectations of increasing demand for chlorotoluene derivatives as pesticide and pharmaceutical raw materials domestically and abroad.

Capital increased to 780 million yen.

Completion of Plant 6. Dichloro‑p‑xylene: Plant 6: Started operation as a facility to enter the xylene chlorination field and address the inability of existing chlorination equipment to meet demand. It includes crystallization, filtration, and drying processes, and produced the company’s first powdered product. The main product, α,α‑dichloro‑p‑xylene, has seen steady demand growth, and the same xylene derivative, isophthaloyl chloride/terephthaloyl chloride, has also increased in demand.

Obtained ISO 9002 certification.

Completion of Plant 7. Constructed to meet the rapid increase in demand for α,α‑dichloro‑p‑xylene in electrical material applications. It has since operated as a plant for producing raw materials for high‑performance materials.

Obtained ISO 14001 certification.

Obtained ISO 9001 certification (transition).
