GB 18383-2025General technical requirements for products with filling materials (English PDF)

1 Scope

GB 18383-2025 is the Chinese national standard on general technical requirements for products with filling materials, in the field of textile and leather technology. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 2 December 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2026. Classification: ICS 59.080.99, CCS W59. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document defines the terms and definitions related to products with filling materials, specifies the requirements, sampling, judgment rules, and marking of products with filling materials, and describes the corresponding inspection methods. This document applies to products with filling materials.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 filling materials A collective term for natural fibers, chemical fibers, and their mixtures used for filling and padding.

3.2 products with filling materials Products for which filling materials and their processed wadding sheets, felt pads, etc. are used as filling or padding materials. NOTE. Products with filling materials are divided into daily use products with filling materials and non- daily use products with filling materials.

3.3 daily use products with filling materials Products with filling materials that come into close contact with the human body in daily life. NOTE. Daily use products with filling materials mainly include clothing, footwear and hats products with filling materials, such as winter clothing, down clothing, cotton clothing, cotton shoes, and cotton hats; bedding products with filling materials, such as quilts, mattresses, pillows, and cushions; upholstered furniture products with filling materials, such as mattresses, sofas, and seating/lying cushions; and toy products with filling materials, such as plush toys.

3.4 non-daily use products with filling materials Products with filling materials other than those for daily use. NOTE. Non-daily use products with filling materials mainly include building insulation materials, agricultural insulation materials, transportation packaging materials, decorative materials, and building sound insulation materials, etc.

3.5 textile waste for medical purpose Various fiber products that have been discarded or abandoned by medical and health institutions. NOTE. Textile waste for medical purposes mainly includes obsolete or discarded medical dressings such as absorbent cotton and absorbent gauze, as well as clothing, products with filling materials, and other fibrous products worn by medical staff and patients.

3.6 foreign matter The collective term for non-flocculating fiber substances that are mixed into filling materials.

3.7 fibre waste Single fibers or bundles of fibers that fall off, are discarded, or are detached during the production and processing of fibers or fiber products.

3.8 fibre products waste Thread ends other than fiber waste, and offcuts from fabrics, wadding sheets and felt pads, which are generated during the processing and production of fiber products.

3.9 unused fibre products waste Waste generated during the production and processing of fibers and their products (such as spinning, weaving, printing and dyeing, and cutting), as well as clothing, household fiber products, industrial fiber products and other fiber products that are discarded or abandoned before use. NOTE. Waste materials include fiber waste and fiber products waste.

3.10 used fibre products waste Fiber products that are discarded or abandoned after use. NOTE. This includes clothing, household fiber products, industrial fiber products, and other fiber products that have been discarded or phased out after use.

3.11 mechanically recycled fibre Fibers that are made from fiber products, fiber waste, and fiber products waste through physical and mechanical processes. NOTE. Physical-mechanical processing refers to the process of using mechanical methods to cut, tear, and open fiber waste, fiber products, and their waste to obtain fibers.

3.12 recycled chemical fibre Fibers that are made from unused/used fiber product waste or waste polymer materials through processes such as physical melting, chemical regeneration, and physicochemical processes. NOTE

1.Physical melting process refers to the reprocessing of thermoplastic unused/used fiber product waste or waste polymer materials through heating and melting. Chemical regeneration process refers to the process of depolymerizing, removing impurities, repolymerizing, or decomposing unused/used fiber product waste, or waste polymer materials into new raw materials under certain chemical process conditions. Physicochemical process refers to the process of blending and modifying unused/used fiber products waste, or waste polymer materials through heating and melting under the action of different functional additives. NOTE
