B-grade Roll
A B-grade roll is a roll of textile that has been inspected and found to have textile defects or deviations from specifications, and is traded separately from normal regular-grade goods.

Definition and Overview
B-grade roll refers to a roll of textile that falls outside the standard for regular goods due to weaving flaws, stains, uneven dyeing, holes, or variations in width or hand feel. The type and degree of defects, as well as the judgment criteria, differ by textile and trading partner.
It does not mean that the overall quality of the textile itself is uniformly low. There are various reasons a roll may be classified as B-grade, such as having defects in part of the roll or being usable for production but not meeting normal sales standards.
Situations in which it is used in trade
B-grade rolls are used when, after textile inspection, they are managed, sold, or considered for disposal separately from regular goods. For the buyer, the question is whether they can be used for prototyping, samples, accessories, small-lot cutting where defects can be avoided, and so on.
In transactions, simply labeling something as B-grade makes it difficult to judge whether it can be used for a given application, so it is important to share the defect type, location, range, roll length, and the length that can actually be used. The condition may also differ from roll to roll.
- Type of defect and impact on appearance
- Defect location and spacing, distance from the selvage
- Roll length, usable length, and the range that can be avoided in cutting
- Whether the width, color, or hand feel differs from the regular goods
- Responsibility in the event of returns, exchanges, or after use
Key points to check and handling of numbers
When checking, the basic approach is to unroll the roll and actually inspect the defects, then determine whether it can be used based on the size and layout of the cutting pattern. For patterned textiles, light-colored textiles, and textiles with surface variation, even small defects can affect how noticeable they are and how they affect pattern matching.
There is no uniform guideline for defect count, defect spacing, length to deduct, or discount rate. Priority should be given to the textile inspection standards and agreed terms of the trading partner, and for projects that require a specific quantity, it is important to check the details and photos for each roll and separately estimate the usable quantity.
Differences from similar terms
Textile defects refer to individual flaws appearing in the textile, such as weaving flaws or stains. B-grade, on the other hand, is a term that indicates how a roll is classified in trade because of those defects or differences from specification.
Random-length rolls generally refer to rolls whose lengths are irregular or that include short rolls. Even if a roll is random-length, it may have no quality issues, so it does not mean the same as B-grade. Textile inspection is the inspection process for checking such defects and specifications.
Frequently Asked Questions
Can B-grade rolls be used for apparel?
Whether they can be used depends on the type of defect and the product specifications. Even if a defect can be avoided by cutting, it is necessary to confirm the required yardage, pattern matching, and reproducibility in mass production. For products where appearance is important, it is especially important to check whether the defect will appear in a conspicuous location.
How do you estimate the required quantity of B-grade rolls?
Do not take the stated roll length as the usable quantity as is; instead, check the defect location and the portions that cannot be used in cutting. Allow extra margin for the required number of products, and confirm in advance the condition differences from roll to roll, whether additional arrangements are possible, and whether the same color and hand feel can be secured continuously.
Are B-grade rolls and random-length rolls the same?
No, they are not the same. B-grade refers to a classification of rolls that fall outside quality standards, while random-length rolls generally refer to rolls with irregular lengths. Even a short roll is not necessarily B-grade if there are no quality issues, and some rolls may fall under both categories.
