Official rule text
[CL-08-OM-HS] - Value of 'cbc:ItemClassificationCode[@listID="HS"]' is not a valid 12-digit Oman HS code (CL-08-OM-HS).
What this means
The item's HS (customs classification) code must be a valid 12-digit Oman HS code. A 6-digit ISIC code does not belong in this field - it goes in the separate industrial classification field.
