As of April 2026, the IS 456:2000 (Plain and Reinforced Concrete - Code of Practice) remains the foundational structural design code in India, but it must be applied in conjunction with the latest Amendment No. 6, which was released in June 2024. Latest Amendment Details (Amendment No. 6 - June 2024)
New Cement Types: Introduces specifications for Composite Cement and Portland Calcined Clay Limestone Cement.
Mineral Admixtures: Recommends enhanced guidelines for using materials like Silica Fume, Metakaolin, and Ground Granulated Blast Furnace Slag.
Concrete Durability: Modifies requirements for cement content, water-cement ratios, and aggregate sizes, especially in relation to limestone-based cements.
Structural Revisions: Updates clauses on nominal cover, lap length of hooks for bars in direct tension, and strength of welds. Where to Find the PDF

While you search for the IS 456 latest amendment pdf of the current code, start preparing for the next revision. Based on the BIS draft, expect:
Until the new revision is notified, your go-to document remains IS 456:2000 with Amendment No. 4.
⚠️ Warning: Free PDFs circulating on academic or file-sharing sites are often outdated (pre-amendment) or pirated. Using them for official construction can lead to legal penalties, structural failure, or insurance invalidation.
| Amendment Number | Year | Key Focus Area | |----------------|------|----------------| | Amendment 1 | 2001 | Editorial and minor corrections | | Amendment 2 | 2004 | Durability, cover requirements | | Amendment 3 | 2007 | Reinforcement detailing and fire resistance | | Amendment 4 | 2013 (Reaffirmed 2021) | Limit state design revisions, material specifications, durability enhancements |
Note: The BIS periodically "reaffirms" standards. The latest reaffirmation in 2021 confirms that Amendment No. 4 remains current without technical changes. No new numbered amendment has been issued after 2013 as of 2026.
Let's clear the confusion. The base code is IS 456:2000. Over time, BIS issued four amendments:
| Amendment No. | Year Issued | Key Focus Area | |---------------|-------------|----------------| | 1 | 2001 (Reaffirmed) | Minor corrections to clauses on creep and shrinkage. | | 2 | 2005 (Reaffirmed) | Modifications to steel grades (Fe 500, Fe 550). | | 3 | 2007 (Reaffirmed) | Updates to clause on minimum eccentricity and slenderness limits. | | 4 | 2013 (Reaffirmed 2021) | Latest active amendment – Major changes to durability, cover, and crack width. |
After Amendment No. 4, the code was reaffirmed in 2021 without further technical changes. Therefore, as of 2025, IS 456:2000 with Amendment No. 4 is the legally current version.
Yes. All structural designs submitted for approval after 2014 must comply with the latest amendment unless exempted by local municipal authority.
