ISO 7482-1:1998

Overview

ISO 7482-1:1998 - Raw goat skins: Part 1 - Descriptions of defects defines and describes the range of visual and structural defects that can occur on raw goat skins. The standard covers fresh and cured skins (air-dried, wet-salted, dry-salted) and provides a common vocabulary for inspection, quality assessment and communication across the leather supply chain.

Key topics

• Presentation terms: standard ways to present skins for inspection - folded skins, open (flat) skins, and sleeve skins.
• Three defect categories:
  • Ante-mortem defects (occur before slaughter): ecchymosis (bruising), fire-marks, grain damage, greasy skin, pox marks, ringworm, ectoparasite damage (Demodex, lice, Psoroptes, Sarcoptes, ticks, warbles), thin skin.
  • Post-mortem defects (from flaying/handling): butcher strain, deformation, extras (horns, hooves), flay cuts, freezing damage, nicking, patches of grease or flesh.
  • Preserving and storage defects: issues related to preservation method (dry salted, wet salted, air-dried) such as mineral-salt discoloration, putrefaction/decay, blood stains, case hardening, Dermestes (larval) attack, folding crack, glossiness, mildew, sticking, strain marks, red heat, and salting defects.
• Descriptive focus, not grading metrics: the standard provides definitions and visual/structural descriptions of defects rather than numerical defect limits or grading thresholds.

Applications and users

ISO 7482-1:1998 is practical for:

• Tanneries and leather processors - for incoming inspection and process planning to anticipate defects that impact tanning, splitting and yield.
• Hide and skin traders / exporters - to standardize defect reporting and reduce disputes during procurement and sales.
• Quality control teams - to document defect types and decide on remedial or rejection actions.
• Veterinary and animal husbandry advisors - to identify disease- or parasite-related defects that reflect animal health issues.
• Standards bodies and auditors - to harmonize vocabulary across Parts 2 and 3 of ISO 7482 and with other hide/skin standards.

Practical value

• Promotes consistent defect identification and clearer communication across the supply chain.
• Helps anticipate processing challenges (e.g., greasy or thin skins causing hollowing, or salt-related bacterial issues).
• Supports risk mitigation in storage and preservation choices, reducing losses from putrefaction, mildew, or red heat.
