Sixty percent of producton centers had given gambier which was capable to produce leather met the quality requirements. The result also found there were a strong relationship between gambier characteristics and quality of tanned leather, e.g. gambier tannin level and bonded-tannin in tanned leather (r=0.980), gambier catechins level and bonded-tannin in tanned leather (r=0.967) and gambier ash content and bonded-tannin in tanned leather (r=0.852). Highest tannin level would produce good tanned leather.
