BIS Certification Consultant for HDPE/PP Woven Fertilizer Bags | IS 9755:2021 | Qualitance India
INTRODUCTION
Manufacturers of fertilizer packaging bags must ensure that their products meet the applicable requirements for strength, dimensions, material quality, stitching, drop resistance and other specified performance characteristics. These requirements are important for protecting fertilizers during storage, handling and transportation.
In India, HDPE and PP woven sacks used for packaging fertilizers are covered by IS 9755:2021 — Textiles: High Density Polyethylene (HDPE)/Polypropylene (PP) Woven Sacks for Packaging Fertilizers — Specification.
The applicable Quality Control Order requires covered fertilizer packaging sacks to conform to the specified Indian Standard and bear the BIS Standard Mark under a valid licence. Manufacturers, importers, exporters and suppliers should therefore assess the applicable certification requirements before supplying these bags to the Indian market.
Qualitance India provides BIS certification consultancy, application documentation support, product testing coordination, product grouping guidance and manufacturing quality-control support for HDPE/PP woven fertilizer bags.
1. What Is IS 9755:2021 for HDPE/PP Woven Fertilizer Bags?
IS 9755:2021 specifies requirements for woven sacks manufactured from high-density polyethylene (HDPE) or polypropylene (PP) for packaging fertilizers. These bags are used for packaging and transporting fertilizer products and must meet the applicable construction, material and performance requirements of the standard. The BIS Product Manual for IS 9755:2021 provides guidance on product grouping, raw materials, sample requirements, testing equipment, factory quality control and the scope of the BIS licence. Important areas covered by the standard include:- HDPE or PP raw materials.
- Woven fabric construction.
- Sack dimensions and tolerances.
- Fabric mass and sack mass.
- Fabric breaking strength and elongation.
- Liner requirements, where applicable.
- Lamination requirements, where applicable.
- Bottom seam and stitching.
- Capacity requirements.
- Drop impact strength.
- UV resistance for applicable products.
- Printing, marking, packaging and storage.
2. Is BIS Certification Mandatory for Fertilizer Bags in India?
Yes. BIS certification is mandatory for HDPE/PP woven sacks covered by the Textiles—HDPE/PP Woven Sacks for Packaging Fertilizers (Quality Control) Order, 2023, subject to the applicable provisions and exemptions. The order identifies IS 9755:2021 as the applicable Indian Standard and requires covered products to conform to the standard and bear the BIS Standard Mark under a licence issued according to Scheme-I of the BIS Conformity Assessment Regulations, 2018. The original QCO was published in December 2023 and was subsequently amended in June 2024. The applicable implementation dates and any later amendments should be checked against the current official notification before making a compliance decision. The original order excludes products manufactured for export from its scope. Manufacturers should verify the precise conditions applicable to their transaction rather than assume that all products or sales are exempt.

5. Raw Material Requirements for HDPE/PP Fertilizer Bags
Raw material conformity is an important part of BIS certification for woven fertilizer bags. According to the BIS Product Manual:- HDPE used for manufacturing tapes must conform to IS 10146.
- PP used for manufacturing tapes must conform to IS 10910.
- Where a liner is used, the permitted liner material may include LDPE, LLDPE, HMHDPE or HDPE, subject to the applicable requirements.
- The manufacturer must obtain a test certificate from the raw material supplier for each lot of HDPE, PP or liner received, indicating conformity with the relevant requirements.
6. Technical Requirements and Testing for HDPE/PP Woven Fertilizer Bags
Product testing is required to demonstrate conformity with IS 9755:2021. The precise test programme depends on the material, type, construction and other applicable product features.6.1 Dimensions and construction
The sack must comply with the specified dimensions and construction requirements. Testing and inspection may include:- Inside length and width.
- Ends per decimetre.
- Picks per decimetre.
- Fabric mass.
- Sack mass.
- Construction and visual appearance.
6.2 Fabric strength and elongation
The woven fabric must meet the relevant breaking-strength and elongation requirements. These characteristics help assess the fabric's ability to withstand the stresses encountered during filling, handling and transportation. The BIS Product Manual refers to the applicable test methods, including IS 1969 (Part 1), for relevant fabric-strength and elongation testing.6.3 Liner requirements
Where a liner is provided, the applicable requirements may include:- Liner material.
- Thickness.
- Length and width.
- Width allowance relative to the sack.
- Bottom sealing of a loose liner.
6.4 Lamination
For laminated sacks, applicable tests may include lamination mass and lamination overhang. Relevant requirements should be checked against the standard and the proposed product construction.6.5 Bottom seam and stitching
The bottom seam must meet the applicable construction and strength requirements. The Product Manual identifies checks relating to bottom-seam strength and stitching arrangements. These are important for reducing the risk of seam failure during filling and handling.6.6 Capacity and drop impact strength
The sack must meet the specified nominal capacity and relevant drop impact requirements. Drop impact testing evaluates the sack's performance under the prescribed test conditions. The exact method and acceptance criteria must be taken from IS 9755:2021.6.7 UV resistance
For sacks made from UV-stabilized material, the applicable UV resistance requirement must be met. The Product Manual specifies that UV-stabilized HDPE/PP woven fabric must retain at least 50% of its original breaking strength after exposure to UV radiation and weathering under the prescribed test method. The relevant breaking-strength measurements and exposure conditions must be evaluated in accordance with the standard.6.8 Ash content and other applicable tests
The standard includes ash-content and other specified tests for relevant product configurations. The applicable tests depend on the sack construction and material. Manufacturers should not assume that every test applies identically to all variants. The laboratory testing plan should be based on the current standard, the Product Manual and the proposed licence scope.7. Sample Requirements for BIS Testing
The BIS Product Manual for IS 9755:2021 specifies the following sample quantities:- HDPE/PP granules: 1 kg.
- Unlaminated and laminated fabric: 1 metre × 1 metre, as applicable.
- Stitching thread: Required for UV-stabilized sacks, as specified in the manual.
- Finished woven sacks: 10 to 12 sacks.
