Pile fabrics and terry fabrics, knitted or crocheted

1. Scope and Applicability

This PCR covers the manufacture of knitted or crocheted pile fabrics and terry fabrics classified to CPC 3.0 code 28110. It applies to greige or finished fabric sold by mass at the manufacturing gate when the pile or loop construction, fibre composition, fabric state, and included processing route are declared.

It excludes woven pile and chenille fabrics, woven terry towelling, narrow fabrics, tufted fabrics, nonwovens, carpets, garments, made-up textile articles, and ordinary knitted or crocheted fabrics without a pile or terry structure. Fibre and yarn production are linked upstream datasets rather than foreground operations unless explicitly brought into scope.
