What is JIS ?
JIS stands for :
Japan Industrial Standards( Japan’s national standards )
JIS is : A basis of Japan Quality.
JIS is : What QTEC labｓ work with.
3
Japan Quality ?
A few examples: Think of automobiles from Japan. Think of electric appliances of Japan. Think of optical apparatuses of Japan. Think of office appliances from Japan.
--- They all give you some idea about what Japan Quality is meant to be, in the textile & garment industry as well.

Where does Japan quality come from ?
The clue : The Japanese consumers.Traditionally, the Japanese consumersare highly quality-conscious. They always look for quality, not just appearance or price.Therefore it is advisable that you ensureand prove the quality of your products.Most of the Japanese retailers may ask test results report before shipment.
5
How can we ensuresatisfying quality?
First, better understand the market.(There are some regulations to understand.)
Secondly, must learn requirements of each customer. (They may vary. )
Thirdly, better be familiarized with JIStests for textiles and evaluation process.
Lastly, apply for JIS tests and have the products evaluated.
6
JIS which is used for quality evaluation of casual wears is mentioned only test method.
Each retailers set up their quality criteria about their selling products, respectively.
So you need follow your buyer’s quality requirement.
Who set up criteria?
