The present document highlights by means of different icons at the heading of every section which are the main advantages related to good and best manufacturing practices implementation:

In order to help in the comprehension of this document, please, read below definitions carefully in order to ensure a proper understanding of this manufacturing code:

Auxiliary products or auxiliaries: Chemicals used during the manufacturing processes of textile and leather articles excluding dyestuffs/pigments and commodity chemicals.

Cellulosic regenerated fibre: Fibres obtained by the conversion of natural cellulosic materials into a soluble cellulosic derivative and its subsequent regeneration into a fibre. Typical examples of this kind of fibres are viscose, lyocell, modal and acetate.

Coating lot: Quantity of fabric that has been coated at the same time, using the same machinery and the same recipe until the manufacturing process is stopped overnight or any lot number of the chemicals used is changed.

 Coating lot number: Identification code assigned to a coating lot for traceability purposes.

Commodity chemicals: Chemicals produced at a very large scale to satisfy global markets. In the specific case of leather and textile sectors, they are acids, sodium chloride, sodium sulphate, sodium carbonate, chromium sulphate, caustic soda, hydrogen peroxide, sodium hydrosulphite, among others.

Detection limit: Lowest concentration of a substance that could be distinguished from the absence of that substance that could be detected using a specific analytical technique.

Dyeing lot: Quantity of yarn, fabric, leather or garments that has been dyed at the same time, using the same machinery and the same recipe.

Dyeing lot number: Identification code assigned to a dyeing lot for traceability purposes.

Fabric batch: Each set of fabric produced by the same supplier, using the same yarn lot number and the same type of machinery, regardless the number of deliveries and their service dates. 

Finishing process: Wet manufacturing process performed after dyeing and/or printing processes.

Finishing lot: Quantity of fabric or leather that has been subjected to a finishing process at the same time, using the same machinery and the same recipe.

Finishing lot number: Identification code assigned to a finishing lot for traceability purposes.

INDITEX direct supplier: Yarn, fabric, leather, footwear or garment supplier who have a direct commercial relationship with INDITEX.

INDITEX sustainability policies: Requirements included in INDITEX sustainable manufacturing code, product health standard (CTW) and MRSL.

Internal order number: Code assigned to each processing subset of yarn, fabric, leather or garments from one initial purchase order.

Leather batch: Each set of leather produced by the same mill, using the same recipe and the same machinery, regardless the number of deliveries and their service dates.

Lot number: Identification code a dyestuff/pigment and/or auxiliaries supplier assigns to their chemical products for traceability purposes.

Manufacturing Restricted Substances List (MRSL):2 Register of chemical substances that are subjected to a usage ban/restriction during the manufacturing process of an article.

Printing lot: Quantity of fabric, leather or garments that has been printed at the same time, using the same machinery and the same recipe until the manufacturing process is stopped overnight or any lot number of the chemicals used is changed. Additionally, in case printing panels or rotary screens are cleaned or changed it will be also considered a different printing lot.

Printing lot number: Identification code assigned to a printing lot for traceability purposes.

Production lot: Quantity of yarn, fabric, leather or garments that has been dyed, printed, washed, finished or coated at the same time, using the same machinery and the same recipe.

Raw materials: Yarn, fabric and leather.

Ready to print fabric: Fabric the has been previouly pre-treated (desized, bleached, etc.) in order to be able to perform a proper printing.

Recipe: Formulation of dyestuffs/pigments and auxiliaries used for pretreatment, dyeing, printing, washing, finishing or coating yarn, fabric, leather or garments.

Note: In case of continuous dyeing processes, changes in the concentration or lot number of the chemicals used, will be considered as a different recipe.

Secondary component: Textile or leather element of an article, different to the main and secondary fabrics, the percentage of which not exceeds 5 % or 15 % by weight or area, respectively. Elbow patches, edgings and embroideries, among others, are examples of secondary components.

Sub-suppliers: Suppliers of yarn, fabrics, leather or finished articles (garments, footwear and/or textile and leather accessories) to INDITEX direct suppliers who may have their own supply chain. They can be traders or vertically integrated suppliers.

Trans-flock process: Transference of flocks to a textile substrate using temperature

Vertically integrated supplier: Supplier which participates in all or major stages of the production of an article, from the acquisition of raw materials to its production and commercialization.

Washing lot: Quantity of fabric, leather or garments that have been washed at the same time, using the same machinery and the same recipe.

Washing lot number: Identification code assigned to a washing lot for traceability purposes.

Wet processing mills: Dyeing, printing, finishing and coating mills, laundries and tanneries.

Yarn batch: Each set of yarn produced by the same supplier at the same spininig mill and same type of machinery regardless both the number of deliveries and their service dates.
