The SA8000 social accountability management system aims to safeguard the basic rights and interests of humanity.

The essential standards of the SA8000 system have been derived from relevant protocols and other principles of the International Labor Organization (ILO) regarding the prohibition of forced or compulsory labor and freedom of association, global statements regarding human rights and interests, and UN Covenants on children rights and interests. Said standards represent the highest benchmark for the evaluation of corporate social responsibility performance.

M.J. International Group prohibits the hiring of child labor, any form of forced labor, and sexual harassment in accordance with relevant laws. The company voluntarily places increasing emphasis on labor rights and interests, employee care, improvement of labor relations, and compliance with relevant laws and regulations. As a consequence of results accumulated over many years, the Prolong and Mei Jer manufacturing plants in Dongguan, China were internationally recognized through the award of the SA8000 certification in December 2013.

The company makes dedicated efforts in the field of environmental protection with regard to every detail on a daily basis. This includes an employee code of conduct for the purpose of energy conservation and carbon reduction and prevention of resource waste concrete measures ranging from annual inspections of water and electricity pipelines, reuse of waste paper, and turning off of unnecessary water and electricity sources to sorting of garbage, and recycling of waste and scrap metal. The company also places great emphasis on environmental pollution control. Although Guangdong Province has issued a pollutant discharge permit for the company, the pollutant discharge values of the machinery and equipment in the production plants are lower than the required values. The annual test reports for the handling of water, air, and noise pollution meet the relevant criteria of the National Quality Standard Bureau in China and the company has acquired relevant certificates.

In addition, the Dongguan Prolong and Mei Jer plants, which belong to the group, have been awarded the international ISO14001 certification for environmental management systems. The company is committed to pollution prevention, compliance with relevant laws and regulations, constant improvements of the environmental management system, and enhancement of overall environmental performance. The OEM products manufactured by the group are also widely acclaimed in destination countries and meet national inspection standards. They have passed certifications such as BRE A+ and Floor Score, a US certification for indoor air quality and emission standards.

Environmental protection is of utmost importance to 『M.J. International Group』 as a 『Green Enterprise』. PVC flooring materials manufactured by the group are non-polluting, non-toxic, and healthy products, which are recyclable in an eco-friendly manner. The internal production environment is also free from pollution sources and the emphasis lies on the production of healthy and high-quality products in a pollution-free environment. The future direction of R&D efforts will move beyond the properties and limitations of traditional products and will emphasize advanced 『non-print』 and 『non-PVC』 technologies as well as the use of 『eco-friendly and healthy materials』. Research and development of non-polluting and eco-friendly products serves the purpose of increasing added value and fulfilling corporate social responsibility. Under no circumstances is product quality sacrificed for cost. Production processes do not generate environmental pollution or cause harm to the health of consumers.

In 2010, Dongguan Prolong Plastics Product Co., Ltd., a member of the group, was honored with the『Award for Advanced Enterprises in the Field of Energy Conservation』presented by local government units. It also received international recognitions such as ISO 14001 and Floor Score, a US certification for indoor air quality and emission standards.
