BIS Certification Consultancy for Forged/Rolled CTC Segments in India

Forged and rolled CTC segments are specialised steel components used in Crush, Tear and Curl (CTC) machines in the tea-processing industry. These components play an important role in the mechanical processing of tea leaves, making their strength, hardness, dimensional accuracy and manufacturing quality important for reliable operation. Manufacturers and suppliers of forged or rolled CTC segments need to understand the applicable Indian Standard, product testing requirements and relevant BIS certification provisions before entering the Indian market or planning a certification application. Qualitance India provides BIS certification consultancy for forged and rolled CTC segments, helping businesses assess applicable requirements, prepare technical documentation, coordinate testing and understand the relevant certification process. The standard associated with this product category is IS 8748 – Forged/Rolled CTC Segments – Specification. An important technical update is that the earlier IS 8748:1978 was revised as IS 8748:2023, the first revision. The revised standard was established on 3 August 2023, and the Gazette notification specified withdrawal of the 1978 edition from 3 November 2023. <Cite refs={["turn261548search25","turn864228search0"]}/> Businesses should therefore distinguish between the current technical standard and the standard edition referenced in older regulatory documents.

1. What Is IS 8748 for Forged/Rolled CTC Segments?

IS 8748 is the Indian Standard associated with the specification of forged and rolled CTC segments used in tea-processing machinery. CTC stands for Crush, Tear and Curl. In this process, tea leaves are mechanically crushed, torn and curled to produce the desired leaf particle characteristics. CTC segments are components used in the machinery that performs this processing. The applicable standard prescribes requirements and test methods for forged and rolled segments used in CTC machines. The revised edition addresses chemical composition, mechanical properties, dimensional tolerances, freedom from defects, sampling, testing, marking and packing. <Cite refs={["turn864228search5","turn261548search2"]}/>

2. What Are Forged and Rolled CTC Segments?

Forged and rolled CTC segments are steel components manufactured through forging or rolling processes for use in CTC tea-processing machinery. Their performance depends on appropriate material characteristics, manufacturing controls, finishing and conformity with the applicable specification.

Forged CTC segments

Forging involves shaping metal through compressive forces. Depending on the manufacturing process and component design, forging can produce the required geometry and material characteristics for the intended application.

Rolled CTC segments

Rolling shapes metal by passing it through rolls. The process must be controlled to achieve the specified dimensions, shape and relevant material properties.

Why product quality matters

CTC segments are exposed to repeated mechanical operation. Inadequate material quality or dimensional inconsistency may affect the performance, fit or service life of the component. The relevant standard and the manufacturer's product specifications should therefore be considered when establishing manufacturing and inspection controls.

3. IS 8748:1978 vs IS 8748:2023 – What Has Changed?

The first revision of IS 8748 is an important consideration for manufacturers preparing a new certification application or reviewing older technical documentation. The official Gazette notification identifies IS 8748:2023 as the first revision and specifies the withdrawal of IS 8748:1978 from 3 November 2023. <Cite refs={["turn261548search25"]}/>

Particular	IS 8748:1978	IS 8748:2023
Standard title	Specification for Forged/Rolled CTC Segments	Forged/Rolled CTC Segments – Specification
Edition status	Withdrawn technical edition	First revised edition
Technical reference	Earlier specification	Revised specification
Testing	Requirements of the earlier edition	Revised sampling and testing provisions
Chemical analysis	As specified in the older edition	Permits established instrumental or chemical analysis methods
Manufacturing provisions	Earlier requirements	Revised provisions provide greater flexibility in machining methods

The revised edition allows established instrumental or chemical methods for chemical composition assessment and removes prescriptive requirements relating to the sequence of machining operations, allowing suitable manufacturing flexibility. It also sets out sampling and testing provisions relevant to product conformity. <Cite refs={["turn864228search5"]}/> Manufacturers should review the full revised standard before updating technical specifications, inspection plans or certification documentation.

4. Is BIS Certification Mandatory for Forged/Rolled CTC Segments in India?

BIS certification is generally voluntary unless a relevant legal order makes certification compulsory for the product. Where a Quality Control Order applies, the manufacturer or importer must meet the requirements specified in that order. The Steel and Steel Products (Quality Control) Order, 2024 lists IS 8748:1978 – Specification for Forged/Rolled CTC Segments at serial number 130 and specifies implementation with immediate effect. The order also lists relevant ITC (HS) codes for the product category. <Cite refs={["turn261548search23","turn261548search28"]}/> However, IS 8748:1978 was subsequently withdrawn as a technical standard following publication of IS 8748:2023. The BIS compulsory-certification listing also displays the older reference. <Cite refs={["turn261548search25","turn261548search1"]}/> This creates an important distinction between the standard edition shown in the QCO and the revised technical edition.

What should manufacturers and importers verify?

Before manufacturing, importing or selling forged or rolled CTC segments, businesses should confirm:

1. The latest applicable Steel and Steel Products QCO and amendments.
2. The exact schedule entry and product description applicable to CTC segments.
3. The relevant standard edition and any official direction concerning the revised standard.
4. The applicable ITC (HS) classification, where relevant.
5. Whether any exemption, amendment or special condition applies.
6. The BIS licence, testing and marking requirements for the product.

Regulatory caution: Do not assume that the withdrawal of the older standard automatically removes a product from compulsory certification. Equally, do not assume that a QCO reference to a withdrawn edition automatically resolves how the revised edition must be handled. Obtain confirmation of the applicable requirements from the relevant official authority before making a compliance decision.

5. BIS Certification Process for Forged/Rolled CTC Segments

Where BIS certification is applicable, manufacturers must demonstrate conformity with the relevant requirements and follow the prescribed certification process.
