What is CIPET?
CIPET, the Central Institute of Petrochemicals Engineering and Technology, is an Indian government institution that provides testing, certification support, training and research for the plastics and petrochemicals sector. Its laboratories offer accredited testing services, including tests relevant to compostable and biodegradable plastics. For buyers, a CIPET test report is a credible, independent basis for a material claim.
Because CIPET is a recognised national body with accredited laboratories, its reports carry weight with regulators and customers in a way that an unsupported supplier statement does not.
Why does independent testing matter for compostable plastics?
Compostability is a performance property, not a visible one. You cannot tell by looking at a bag whether it will disintegrate within 12 weeks and biodegrade within six months under industrial composting. Only laboratory testing against a standard can confirm that. Independent testing removes the need to take a manufacturer's word for it.
This is why unverified compostable labels are a risk. Without a referenced standard and a test report, the claim is unbacked, and under India's plastic rules that can expose a buyer to compliance problems.
What does CIPET test for compostable plastics?
For compostable materials, relevant testing follows the criteria in the Indian standard IS 17088: disintegration, biodegradation, ecotoxicity and limits on heavy metals. The laboratory reproduces controlled industrial composting conditions to measure how the material behaves, rather than relying on general assumptions.
The output is a documented report a manufacturer can present to regulators and buyers. That report, tied to a named standard, is what separates a verified compostable product from a marketing adjective.
How does CIPET testing fit with certification?
Testing and certification are linked but distinct. Testing generates the data; certification is the formal confirmation that a product meets a standard, often relying on accredited test data. A CIPET report can form part of the evidence supporting a compostability certification, and it also supports compliance under India's regulatory framework.
For a buyer, the practical takeaway is to ask for both the certificate and the underlying test reports, and to check that they reference a recognised standard and an accredited laboratory.
What should a buyer ask their supplier?
Ask which standard the material is tested against, which laboratory performed the testing, and whether you can see the test report and certificate. Confirm that the testing covers disintegration, biodegradation and ecotoxicity, not just a single property. Be cautious of any supplier who offers a compostable logo but cannot produce the data behind it.
Anjaneya Bio Products treats accredited testing and documentation as part of every compostable product we manufacture. The goal of this article is to help you ask sharper questions of any supplier, so a compostable claim is something you can verify rather than simply trust.
Key takeaway
CIPET is an Indian government body providing accredited testing for plastics, including compostability. Because compostability cannot be judged by eye, independent CIPET test reports tied to a standard such as IS 17088 are what make a compostable claim credible and compliant.
