Testing Procedure

Laboratory technicians first grind the leather sample to a specific particle size before performing solvent extraction under controlled temperature conditions. The extract is then filtered and analyzed to measure the presence of these restricted chemical compounds. Calibration curves using certified reference standards ensure the accuracy of the concentration measurements.

Material Scope

Leather footwear and garments are the primary products evaluated using this chemical analysis method. The testing covers linings, uppers and accessory parts that might contain residues from surfactant treatments used during the tanning process. Because these compounds are restricted under global environmental laws, suppliers must prove their products meet the designated limits.

Compliance Verification

Retailers require certified laboratory reports showing that the leather components do not exceed the restricted limits before accepting bulk shipments. If a sample fails the standard, the entire consignment is subject to quarantine or return to the manufacturing site. Mill inspectors use these verified laboratory findings to audit the tanning facilities and enforce cleaner chemical use, protecting the brand from legal actions and consumer returns.
