What is Genuine Organic?
Many countries legislate the use of“organic”term to prevent from frauds. In Japan regulations exist for food and agriculture, but there are no detailed laws regarding organic textile products. We carry out on-site and document inspections annually supervised by ECOCERT, a global organic certification body, to assure that there is no dye transfer or contamination by harmful chemicals in all processes. These rigorous audits are a condition for receiving GOTS and OCS international textile certifications. The TC (Transaction Certificate) is the only document retracing the whole production process and an important evidence required to receive the “organic” qualification.

Quality inspection by black light
A black light fluorescence test is performed on the finished surface to ensure the product is entirely free of chemicals.
During a blacklight fluorescence test, any residual chemical contained in the fabric fluoresces. Chemical fibers are often used for sewing threads even if the fabric is claimed to be organic.
At Heart, in order to protect sensitive skins and babies, we carry out strict black light inspections and check the presence of chemical transfers.
From fabric, batting, sewing thread to quality label, the products we manufacture are thoroughly non-fluorescent. In addition, we completely clean not only delivered products, but also the inside of manufacturing machines. Any fluorescent product will never be sold as organic product.
