Certification FAQ

The entire process can take up to twelve months or more depending on the test scheme required and both the readiness and attentiveness of the applicant. Testing at a BPI-Approved Lab is often the longest part of the process. Tests like Metals, Ash, and FTIR can take less than one month, but timelines depend on available lab capacity, which is outside of BPI’s ability to control. Disintegration testing takes a minimum of 3 months for commercial compostability and 6 months for home compostability, and biodegradation testing takes a minimum of 6 months (commercial) and 12 months (home). When all tests are submitted and samples are sent, the technical review process generally takes 4 weeks to complete. 

There are fees for BPI Certification, BPI Recertification, BPI Sublicensing, and BPI Membership. 

Certification: The application fee is $1,500 USD for new commercial only certifications and $3,000 USD for new commercial and home certifications.  At least $500 USD of the new application fee is non-refundable. Certifications are valid for 3 years. 
Recertification: It is required every 3 years and is $1,000 USD for commercial only certificates and $2,000 USD for commercial and home certificates.  
Sublicensing: If the Licensee and Sublicensee are both active BPI Members, there is no separate cost for a sublicense.  
If the Sublicensee is not a BPI Member: The Sublicensee will be a Reseller. The annual cost of a sublicense for a Reseller is $500/year USD per licensee, which will be prorated based on the original certificate’s expiration date. Either the licensee or sublicensee can be billed directly for this invoice. 
Membership: The BPI Membership and Licensing fee is due every year, with the cost dependent upon the selected membership level. BPI offers different membership categories with varying benefits and annual costs to best fit the needs of member companies. Please visit BPI Membership for details on membership options and costs. 

All certifications and recertifications require, at a minimum, Regulated Metals / Fluorine / Cobalt, Ash (VOC), FTIR, and thickness and grammage (if applicable) measurements. These must have been conducted within the past 12 months. Depending on the specific formulation, other tests might be required on the end product or certain ingredients, as described below. These tests do not have an expiration date for validity purposes.  

Biodegradation testing measures the inherent ability of organic carbon in a material to be consumed by microorganisms and shows that the material or item will not accumulate in nature.  

Disintegration testing measures whether the finished item physically breaks down and falls apart, demonstrates that the item will not create visual contamination in the compost, and indicates that the item is being successfully attacked by microorganisms (so that the carbon is readily available for biodegradation). It is based on the maximum thickness (or grammage for natural fiber) of the finished item. The maximum thickness/grammage of the product used for the disintegration test determines the certified maximum thickness/grammage for the item. Resins and components should be certified to a maximum thickness/usage that will cover the thickest/densest usage of the resin/component by customers.  

Compost Quality testing includes Metals / Fluorine, Ash (VOC), and FTIR, as well as tests for ecotoxicity. These tests and restrictions are designed to ensure that the compostable material or item does not have negative effects on compost quality.  

To read further on all tests, refer to the BPI Certification Schemes. 

No, both must be labeled. The BPI License Agreement requires all BPI-certified products (e.g. bags, cups, cutlery wrappers, forks, pouches) and packaging (both consumer- and market-facing) for BPI-certified products to display the BPI Certification Mark unless an exemption has been granted in writing.

No. BPI Certification is granted through an executed license or sublicense agreement. Your company must obtain a license to use the BPI-Certification mark which is earned through the certification process or by sublicensing a finished product that is already BPI-Certified. To learn more visit the “Before you Start” page.

Resins and Finished Products are certified up to a maximum thickness, as determined by a disintegration test. Prior to the disintegration test, the BPI-approved lab will measure each unique part of an item and calculate the average thickness for each unique part. For paper- and other substrate-based materials, grammage will also be measured.

When resins are tested for disintegration, film samples that have been made out of that resin are typically tested. When a three-dimensional item such as a cup or piece of cutlery is tested in support of a resin certificate, the measurement of the thinnest part of that item is used as the resin’s max thickness. For instance, a bag with a simple heat-sealed edge would be measured at both the seam and a single layer of the bag wall/film. The max thickness of the resin would equal the measurement of the single layer of the bag wall/film and not the thickness of the seam, since there is no evidence to support that a product of uniform thickness at the seam’s higher thickness would break down within the specified timeframe.

The BPI Certification Scheme states that organic fluorinated chemicals, such as perfluorinated and polyfluorinated substances, cannot be present in formulas for BPI Certified items. BPI's rules for fluorinated chemicals are as follows:

1) The product formula must not contain fluorinated chemicals — as evidenced by safety data sheets for all ingredients.

2) Test results from a BPI-Approved lab showing a maximum of 100ppm total organic fluorine.

3) A statement of no intentionally added fluorinated chemicals, signed by the manufacturer.

Commercial Only Certification certifies that items will break down in commercial compost facilities, while Commercial & Home Certification certifies that items will break down in both commercial compost facilities and in properly managed home compost bins.    

These certifications are supported by two separate certification schemes, one for commercial compostability and one for home compostability.  However, the BPI home certification program is built on top of commercial certification, so there are more similarities than differences between the two programs.  The differences are centered around the different operating conditions and subsequent biological environments typically found in the two composting environments.  

The differences include: 

Eligibility criteria – Pet waste products are limited to Commercial Only Certification for use in Canada since backyard bins don’t typically get hot enough to kill the pathogens in pet waste. 

Testing – Disintegration and biodegradation testing temperatures and timeframes differ between the two certifications.  Disintegration testing is conducted at 58 +/-2° C for up to 84 days for commercial certification and at 25 +/-2° C for up to 180 days for home certification.  Biodegradation testing is conducted at 58 +/-2° C for 6 months for commercial certification and at 25 +/-2° C  for 12 months for home certification.   

Regulated metals – there are some differences in allowable thresholds of regulated metals between the certifications, which can be seen here:  https://bpiworld.org/regulated-metals.  

The following are the testing differences between these two certification programs: 

Biodegradation –  

BPI and the French standard require testing the whole product and each individual ingredient used between 1 – 10% (increasing to 15% in July 2026), with the sum of untested ingredients not allowed to exceed 5% (decreasing to 3% in July 2026). 

OK Compost HOME is less strict in that it doesn’t require testing of individual ingredients, and accepts testing of the whole product.  

Disintegration – 

OK Compost HOME allows qualitative disintegration testing to ISO 20200 if the material has already passed commercial disintegration testing. 

BPI requires disintegration to ISO 16929 or 20200 under home temperatures and timeframes.

To add home certification to an existing commercial certificate, you’ll go through the same administrative process as with a commercial certification. When filling out the application, you’ll need to include the certificate number for the commercial certificate to which you’re adding home certification. The application fee is $1500 USD to add home certification to an existing commercial certificate. Upon successful completion of the certification process, you’ll receive a Certificate of Home Compostability and the products covered under the home certification will be indicated as such in BPI’s online catalog of certified products.

The application fee is $1500 USD. A new home certificate adds to a licensee’s certificate count, so additional licensing fees may be incurred if the new certificate takes the certificate count into the next bundle of five. 

About half of the labs approved to conduct testing for BPI certification can run tests for commercial and home certification.  The current list of approved labs can be found here, with labs approved to conduct testing for commercial and home certifications indicated with a ☗ symbol.  

The BPI Home Compostability Certification Scheme is based on the French Standard NF T 51-800. 

Yes, one application can be submitted for commercial & home certification with an application fee of $3000 USD. Testing can be started at the same time, but home testing takes twice as long to complete as commercial testing. Two certificates, one for home compostability and one for commercial compostability, will be issued upon successful completion. 

Yes, if compliant product and packaging artwork is provided to support the Commercial Only compostability claim. Upon completion of the home certification, compliant artwork will need to be provided to support the Commercial & Home compostability claim.    

The main advantages of a joint process are the convenience of submitting one application packet, paying one application fee, providing one set of product and packaging artwork showing compliance with the requirements for a Commercial & Home compostability claim, and the efficiency of utilizing one procedure and process. With a joint approach, the Commercial Only and Commercial & Home certificates are issued at the same time after testing and assessment for both the commercial and home requirements are successfully completed.    

The total application cost is the same whether the certifications are bundled or acquired separately - $3000 USD for Commercial & Home certification or $1500 USD each for Commercial Only certification and Commercial & Home certification.   

Testing for home certification takes twice as long as commercial testing, so if it’s helpful to be able to make a commercial compostability claim first, undertaking the procedures separately would make sense.  

Correct, BPI made industrial certification a prerequisite for home certification for technical, legal, reputation-related, and mission-driven reasons.  You can read more about the rationale behind this requirement here.

Eligibility criteria between the two programs are identical, except pet waste  products are limited to commercial only certification since backyard bins don’t  typically get hot enough to kill the pathogens in pet waste. 

Yes, resins and components can be certified for Commercial & Home Certification.

BPI Certificates have a three-year validity period.  Adding Home Certification to an existing certificate does not extend the validity of either certificate, as the Home Certification is tied to the Commercial Certificate. Section 7 of both BPI Compostability Certification Schemes specifies the three-year validity period.  

A sublicense allows the BPI Certification Mark to be used by a customer of a BPI Member on private label products for resale under the customer's brand. It is a legally binding agreement that includes product titles and SKUs from the BPI Member and their customer. The customer is given access to the BPI Certification Mark files, including a version with their own unique BPI Company ID Number/CERT # to display on the sublicensed products and their packaging, and the sublicensed products are listed under the customer’s name in BPI’s (products.bpiworld.org).

No. All sublicensed products must be manufactured by the BPI Member Certificate Holder at authorized facilities, without exception. If any modifications, such as printing or date labeling, are made by the customer, then BPI must be informed ahead of time or they risk losing the certification. 

If the license holder company is not identifiable on the product (printed items only) and packaging (all items) then it needs to be sublicensed. The company/brand selling the product must have the license to use the BPI Certification Mark whether through a certification or a sublicense.

No. BPI-certified resins, film, granules, components, and intermediates cannot be sublicensed for resale purposes, only finished products. A company can purchase these materials from a supplier to use in a finished product, but the finished product must go through the certification process. Additionally, pet waste bags are restricted to distribution in Canada only.

The sublicensed product must be completely covered by the tests conducted for certification by the licensee. For example, if packaging film uses a hot-sealed edge that is not covered by the original film certificate's disintegration test, the film cannot be directly sublicensed.)

If your company is looking to sublicense from a BPI Member, please visit our searchable catalog for a list of BPI-certified products. You will need approval from the licensee in order to move forward with the sublicense process.
