This study quantitatively validated the applicability of the Global Product Classification for Korea(GPCK), developed for product safety management in online distribution markets, to government safety management policies. A database was constructed by separating and reorganizing raw accident data from the Consumer Injury Surveillance System of the Korea Consumer Agency into morpheme units. Using nominal-scale statistical analysis methods—Cramer's V coefficient and the chi-square test—the effect sizes and homogeneity among six categories of children’s products were analyzed. The results showed that the effect size between injury body parts and injury types was high(p<0.01), and that statistically significant differences were observed in the distribution of injury body parts among products classified within the same subcategory under the standard product classification system(p<0.05). These findings indicate that the GPC structure, which is primarily designed for the classification of distributed products, has limitations in adequately reflecting the detailed criteria required for domestic product safety policies aimed at safety management. Therefore, the study confirms that, in order to effectively apply the standard product classification system to the domestic product safety management framework, it is essential to introduce an attribute system at a level below the Brick level.
