(a) Natural Disabilities
1. The affected skin shows red or purplish-red rashes, with some areas appearing gray-black. Scars or short regrowth of hair can be observed on the fur surface.
2. Sores exhibit scratch marks, with a wrinkled, tooth-like texture on the skin surface. Severe sores may have uneven surfaces, large wrinkles, and flaking plush.
3. Tangled hair can be combed out without catching lint. However, if the base of the plush is heavily matted, combing may result in sparse hair and visible damage. The severity and size determine the grade.
4. White hairs are concentrated in an area no larger than 1 square centimeter and are considered Class B leather. A few misaligned white needles may also be present.
5. The hair tips show a hooked shape, often due to improper skin treatment.
6. White velvet is classified as white, priced at 50% or less depending on quality. Gray velvet is downgraded by one level.
7. Missing hair peaks caused by rubbing or wear appear as bald patches. The severity depends on the size of the worn-out area.
8. Urticaria or dampness in the cage leads to hair loss on the abdomen and around the hock. The base plush becomes thin, and if the bald area exceeds 5 square centimeters, it is graded accordingly.
9. The neck and back ridge are short and thin, creating a gutter-like appearance. The middle part of the back ridge is also thin and sunken, resulting in a slight reduction in grade.
10. Partial or full hair loss occurs due to eating, leaving bald patches. If the bald area is no more than 2 square centimeters, it may still be considered secondary skin, but exceeding this limit reduces the price.
11. Summer hair fur is typically classified as lower-grade skin. However, if the eyes and nose area has summer hair, it is treated as secondary skin.
(b) Man-Made Disabilities
1. A small knife wound, not exceeding 0.5 square centimeters, does not count as a defect. Wounds larger than 2 square centimeters are graded based on their size.
2. If the cut is misaligned or the skin shape is incomplete after cutting, the grade is reduced accordingly.
3. Fluffed needle points indicate damaged hair follicles and fly velvet. The weight and quality determine the final grade.
4. Missing tail, legs, or nose results in a one-level downgrade. If the tail is less than half missing, it is not considered a defect. Missing a leg causes a one-level drop, while a missing nose affects the skin’s completeness. Sparse plush is treated at 50% or 30% of the value.
(c) Non-Seasonal Skin
All skins other than winter (seasonal) skins are considered non-seasonal. Each season has unique characteristics.
1. Early breeding period peeling causes the coat color to fade, reducing flexibility. The neck plate becomes thick and pinkish. This results in a one-level downgrade. If the plush quality or shine is poor, a two-level downgrade applies.
2. In late spring, peeling occurs as winter hair falls and summer hair grows. The plush becomes sticky and dry, with dull color and luster. Floating velvet and needles appear across the body, and the skin becomes thick and dark. Generally, these skins are priced at 10%, with severe cases priced at 2%.
3. Summer hair plush is sparse, the coat appears dark and dull, and the skin is gray with no oil. The plush quality is the lowest. These skins are valued at 2% of the outer skin price.
4. In early autumn, Pi Dong Mao (new fur) begins to grow, but summer hair is not fully shed. The back skin darkens in color. Fur quality is generally 2%-10% of the outer skin value.
5. Late autumn plush approaches maturity, resembling winter hair in color, though the back and hip areas remain dark gray. These skins are priced between 30%-50% of the outer skin value.
