What is the difference between condition grading and authentication?

Condition grading and authentication are distinct trust services. Grading assesses a garment's physical condition — wear, damage, function — on a standardized scale (GradeThread's 1.0–10.0). Authentication verifies that an item is genuine and not a counterfeit. GradeThread grades condition; it does not authenticate. A buyer often wants both answers, but they come from different checks.

Does a GradeThread grade prove an item is authentic?

No. A GradeThread grade certifies condition, not authenticity. It documents how worn or flawed a specific garment is, on a published rubric, with a verifiable certificate. It does not verify the brand or that the item is genuine — that is authentication, a separate service.

Do I need both grading and authentication?

It depends on what you sell. For most pre-owned clothing, condition is the buyer's main risk — 'is it as described?' — so a standardized condition grade and certificate is the trust signal that matters. For high-value designer or hyped items where counterfeits circulate, authentication is also worth it. Grading and authentication complement each other; neither replaces the other.

Condition grading vs. authentication

Condition grading and authentication are distinct trust services. Grading assesses a garment's physical condition — wear, damage, function — on a standardized scale. Authentication verifies that an item is genuine and not a counterfeit. GradeThread grades condition; it does not authenticate.

Condition grading answers

"What state is this specific garment in?" — how worn, flawed, clean, and structurally sound it is, scored on the 1.0–10.0 scale with a verifiable certificate.

Authentication answers

"Is this item genuine?" — whether a branded piece is real or a counterfeit. It's a separate check, done by specialist authenticators, and GradeThread does not perform it.

Why they're complementary

A buyer often wants both answers, but they solve different risks. For most pre-owned clothing, condition is the primary concern — "is it as described?" — so a standardized condition grade and certificate is the trust signal that reduces returns. For high-value designer or hyped items where counterfeits circulate, authentication also matters. Neither replaces the other; see how condition grading works in our methodology.
