Purpose -This study aims to explore the barriers to implementation of ISO 9000 in China, and to identify how these barriers can be overcome. Design/methodology/approach -Using a structural questionnaire survey, this paper examines the main barriers for enterprises in effective implementation of the ISO 9001 standard. Findings -This paper highlights the problems in implementing the standard, which determines the sustainable implementation, including: short-sighted goal for "getting certified"; over-expectation on the ISO 9001 standard; mandatory requirement (not wholehearted commitment) in some industries; and following others (the trend) in certification. With regard to the effective audit of the ISO 9001 standard, the main problems were explored, including: lack of commitment from some certifying bodies; excessive competition between certifying bodies; and offering of a total packaged service from consultancy to certification by certifying bodies. Practical implications -The ISO 9000 series have permeated into all industrial sectors. Although there are many stories of successful adoption of ISO 9001, problems in implementing the standards need to be explored, which may affect the sustainable implementation. Originality/value -Based on the analysis, the paper proposes that the government should improve the legal framework and enforcement schemes to strengthen supervision and control for effective auditing of ISO 9000 standards.
