Molded Pulp Sustainability Certification (FSC, PEFC & Recycled Fiber) FAQ
---
What is the difference between FSC and PEFC certification for molded pulp?
Both are forest certification systems with chain-of-custody (CoC) programs that track certified fiber from the forest through every processor to the finished product. Each runs its own standards, accredited auditors, labels, and public certificate database. A molded pulp product can carry an FSC or PEFC claim only when every fiber source in its supply chain holds a valid CoC certificate for the relevant scheme. Recycled fiber products follow a separate route — recycled-content certification under either scheme requires documented recovered input rather than forestland certification.

Does FSC or PEFC certification apply to molded pulp made from recycled fiber?
Yes, in a different form. Both schemes run recycled-content certification for products made from recovered paper, and most molded pulp is produced from recycled sources. A supplier can hold forest CoC for virgin fiber input, recycled-content certification for recovered input, or both — covering different product lines. Buyers should ask which certificate covers the specific pulp the part is made from, not which label the company displays on its website.

What documents should a buyer request to verify a supplier's certification claim?
Three documents plus one database check: a current chain-of-custody certificate naming the supplier's facility and scope, an invoice or delivery note from the certified fiber supplier referencing the certificate number, and the supplier's own sales document carrying the same number for the product. Then confirm the number in the issuing scheme's public certificate registry. A sustainability claim without a certificate number that checks out is a marketing statement.

Can a supplier display the FSC or PEFC logo on molded pulp products?
Only under the scheme's label rules and only for certified product lines. Logo use is regulated by each scheme: the logo may appear only on products whose fiber is covered by a valid chain-of-custody certificate, with the certificate number and license code shown. Suppliers who offer to "add the logo" without reference to a certificate number and license are not following scheme rules — logo decoration without certification is a compliance risk for the buyer's own claims as well.

Does certified fiber change the mechanical performance of molded pulp?
No. Certification describes fiber origin and stewardship; performance is a separate measurement track. A certified part still must meet the same grammage, moisture, burst, and compression requirements as any other part, tested against the same standards. Buyers should keep the two conversations separate in supplier evaluation: certification documents for origin claims, test data for performance claims, and no single label covers both.

How do compostability claims relate to fiber certification?
They are different claims with different verification. Fiber certification (FSC, PEFC, recycled content) proves where the fiber came from; compostability certification — such as BPI's program under named standards — proves how the finished product behaves at end of life. A molded pulp part can be certified for recycled content, compostability, both, or neither, and each claim requires its own certificate and test documentation. Buyers verify each in its own registry rather than accepting one logo as proof of everything. (Source: BPI — Certification Programs, Compostable & Bio-Based Products, 2024)
