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.
