Carhartt Authenticity Check: How to Spot Fakes and the Difference from WIP | RE-USE TOKYO
Authentication Basics
Carhartt authentication primarily involves comprehensively checking the product number, tags, stitching, material, and attached parts.
Founded in 1889 as a workwear brand, its robust construction is its most significant feature.
Counterfeits often fall short in fabric thickness and stitching quality.
⚠ Carhartt has two lines: "Carhartt" and "Carhartt WIP." Be careful not to confuse them, as their tag specifications differ.
⚠️ Authentication Criteria Emphasized by RE-USE TOKYO
Product Number (Style Number) Matching: Approx. 35% → Verification of consistency between product number and actual specifications (model, color, material)
Tags/Labels (Age Consistency): Approx. 30% → Logo design, country of origin notation, font, product number format
Material/Fabric Quality: Approx. 20% → Thickness, weight, and feel of duck canvas
Stitching Quality: Approx. 10% → Double/triple stitching, reinforcement stitching, thread finishing
Zippers/Hardware: Approx. 5% → Quality of snap buttons, zipper operation (※ zipper alone is not sufficient for authentication)
※ This is an estimated guideline based on experience, and authentication factors may vary depending on the product.

⚠ Important Notes
Carhartt vs Carhartt WIP: The main Carhartt line and Carhartt WIP (Work In Progress) are distinct lines with different tag and product number systems. WIP is a fashion line marketed in Europe, so its specifications and silhouettes differ from the main line.
Regarding Country of Manufacture: Items made in the USA were primarily produced until the early 2000s, but some models continued to be made in the USA after that. Mexican-made items date from the 2000s onwards. After that, Vietnam, China, etc., are also legitimate manufacturing locations. Do not judge an item as counterfeit based solely on the country of manufacture.
Union Label: ACWA/UNITE labels can be found from the late 1960s to the early 2000s. The presence of this label is strong evidence of an authentic USA-made item, but its absence does not automatically mean it's counterfeit.
Regarding Zippers: Carhartt has used numerous zipper brands over the years, including Talon, Ideal, YKK, and Scovill. Authentication cannot be done based solely on the zipper brand.
Regarding Product Number (Style Number): Verifying that the product number on the tag (e.g., J130, J97, C61) matches the actual item's specifications (model, color, material) is a crucial authentication point.
Caution in the Used Clothing Market: Be especially careful as fakes are prevalent for popular models such as Detroit Jackets, Active Jackets, Duck Jackets, Chore Coats, and Santa Fe Jackets.
Our Inspection Policy: At RE-USE TOKYO, we do not authenticate based solely on tags. We comprehensively check the product number, age, country of manufacture, stitching, material, and details, and only stock items that meet our standards.
This guide is based on knowledge accumulated through actual sourcing and inspection operations.
