IS 16709:2017
PP woven, laminated, block bottom valve sacks for packaging 50 kg cement
Standard Introduction
IS 16709:2017 specifies polypropylene woven, laminated, block bottom valve sacks used for packaging, storage and distribution of 50 kg cement. BIS lists amendments from 2021 and 2023, so the base edition alone is not the complete current technical baseline.
India's Quality Control Order makes conformity and the BIS Standard Mark under a Scheme-I licence mandatory for covered goods from 6 November 2026. Product construction and intended use must be checked carefully because similar woven sacks are covered by different Indian Standards and implementation dates.
Mandatory from 6 November 2026
India's current BIS implementation list and S.O. 5479(E) set 6 November 2026 as the implementation date for the IS 16709 Quality Control Order.
Narrow Product Scope
The standard covers polypropylene woven, laminated, block bottom valve sacks used for packaging, storage and distribution of 50 kg cement. Similar woven sacks can fall under different Indian Standards.
BIS Licence and Standard Mark
The QCO requires covered goods to conform to IS 16709 and bear the BIS Standard Mark under a Scheme-I licence. BIS is the certifying and enforcing authority.
list_alt IS 16709 QCO Decisions
- Confirm the sack is a PP woven, laminated, block bottom valve design for 50 kg cement
- Separate IS 16709 products from conventional 50 kg cement sacks and other laminated woven sacks
- Obtain the current IS 16709 text and both amendments before setting specifications
- Map construction, fabric, dimensions and valve design to controlled drawings
- Plan required material and performance testing with a BIS-recognized laboratory
- Apply for and maintain a BIS Scheme-I licence for the approved product scope
- Use the Standard Mark only under the licence and approved marking controls
- Control raw materials, production, sampling, records and product changes after approval
Who Needs to Comply?
Indian and foreign manufacturers of PP woven, laminated, block bottom valve sacks for 50 kg cement; importers and cement companies sourcing those sacks for the Indian market; BIS licence holders; packaging, quality, testing and procurement teams; and BIS-recognized laboratories assessing the product.
Key Requirements
Confirm Product and Market Scope
Verify that the product is a polypropylene woven, laminated, block bottom valve sack for packaging 50 kg cement and is supplied in India. Do not assume the rule covers every cement sack or every woven package.
Use the Current Controlled Standard
Obtain IS 16709:2017 together with its 2021 and 2023 amendments. The public BIS summary notes changes concerning fabric mass and air permeability; detailed values and methods must come from the authorized standard and amendments.
Control Construction and Materials
Translate the applicable material, laminated tubular fabric, dimensions, construction, perforation and valve requirements into approved specifications, supplier controls and production instructions.
Complete Applicable Performance Tests
Plan the standard's applicable evidence for properties identified by BIS, including fabric strength and elongation, weld strength, drop impact, ash content and air permeability, using approved samples and competent laboratories.
Obtain the Scheme-I Licence
Follow the BIS product manual for application, testing, factory assessment, marking scope and the Scheme of Inspection and Testing. The Standard Mark may be used only under a valid licence for the approved product.
Maintain Production and Change Evidence
Retain incoming-material, process, inspection, test, marking, packing and nonconformity records. Review changes to resin, fabric, laminate, dimensions, valve construction, equipment or suppliers before release and obtain BIS action where required.
Implementation Roadmap
Classify the sack and transaction
Confirm the product is a PP woven, laminated, block bottom valve sack for 50 kg cement supplied into India. Record why IS 16709 applies instead of IS 11652, IS 17399 or another packaging standard, and document any claimed export exclusion.
Establish the controlled requirements
Obtain IS 16709:2017, its 2021 and 2023 amendments, the current QCO and BIS product manual. Convert the applicable construction, material, test, marking, sampling and packing provisions into an owned evidence matrix.
Qualify product and production
Select representative samples, complete applicable testing through a BIS-recognized laboratory, close design or process gaps and prepare the Scheme-I application, factory controls and marking arrangements.
Secure the BIS licence
Complete BIS application review, factory assessment and any required verification. Confirm the approved product scope, marking details and Scheme of Inspection and Testing before applying the Standard Mark.
Maintain licensed conformity
Operate incoming, in-process and finished-product controls; retain test and marking records; manage nonconformities; and assess material, design, supplier and process changes before release.

Classify by construction, filling capacity and intended use before selecting the standard or QCO.
| Reference | Product focus | QCO decision |
|---|---|---|
| IS 16709:2017 | PP woven, laminated, block bottom valve sacks for 50 kg cement | Mandatory from 6 Nov 2026 for covered Indian-market goods |
| IS 11652:2017 | HDPE/PP woven sacks for packaging 50 kg cement | Separate QCO and implementation timetable |
| IS 17399:2020 | PP/HDPE laminated woven sacks for mail sorting, storage, transport and distribution | Different intended use and separate QCO |
| BIS product manual PM/16709/1 | Scheme-I certification, sampling and inspection implementation | Use with the standard and QCO; it does not replace either |
Common Misconceptions
Every 50 kg cement sack is covered by IS 16709.
IS 16709 is specific to PP woven, laminated, block bottom valve sacks. Other constructions can fall under another Indian Standard and QCO.
The 2017 base text is the complete current technical baseline.
BIS lists two amendments from 2021 and 2023. Controlled implementation must include them.
A passing laboratory report is enough to use the BIS Standard Mark.
The QCO requires the mark under a BIS Scheme-I licence, including approved scope and ongoing production controls.
ISO 9001 certification replaces product certification.
A general quality-management certificate does not replace conformity to IS 16709 or the required BIS product licence.
Penalties & Enforcement
The Quality Control Order makes conformity to IS 16709 and use of the BIS Standard Mark under a licence mandatory for covered goods from 6 November 2026. It names BIS as the certifying and enforcing authority and states that contraventions are punishable under the Bureau of Indian Standards Act, 2016. The exact enforcement outcome depends on the conduct and applicable Act provisions; the export exclusion in the original Order must be documented before reliance.
Frequently Asked Questions
When did the IS 16709 Quality Control Order become mandatory?
expand_more
The Second Amendment Order, S.O. 5479(E), was published on 6 October 2026 and set 6 November 2026 as the implementation date. BIS's current upcoming-QCO page shows the same date.
Which sacks are covered by IS 16709?
expand_more
The identified product is a polypropylene woven, laminated, block bottom valve sack for packaging, storage and distribution of 50 kg cement. Conventional HDPE or PP woven sacks and laminated woven sacks for other uses can be covered by different Indian Standards.
Is compliance voluntary?
expand_more
Not for goods covered by the QCO and supplied in India from the implementation date. The Order requires conformity to IS 16709 and the BIS Standard Mark under a Scheme-I licence. IS standards outside a QCO can otherwise be voluntary.
Does the QCO apply to sacks manufactured for export?
expand_more
The original 2023 Order states that it does not apply to goods or articles meant for export. A manufacturer relying on that exclusion should preserve destination, production, inventory and shipment evidence and confirm that the goods are not diverted to the Indian market.
What changed in the standard after 2017?
expand_more
BIS public material identifies two amendments, issued in 2021 and 2023, and describes changes concerning fabric mass and air permeability. The authorized standard and amendment texts control the exact requirements.
Can a supplier self-declare compliance and print the BIS mark?
expand_more
No. The QCO requires the Standard Mark under a BIS licence. The manufacturer must follow Scheme-I certification and the applicable product manual; the mark may be used only for the approved licensed scope.
