Certificates & Test Reports

Every laboratory report for our products, as a PDF you can download right here — no account, no request form.

The reports at the top of each group are the US ones: FDA food contact, CPSIA for lead and phthalates, and the Washington State cadmium limit. Underneath sit the European food contact reports, which test things the US rules do not cover, and the reports for individual components.

Our products are retested every year. The current reports are dated July 22, 2026; earlier years are listed with each product group.

Status and sources

This page was last updated on August 23, 2026. Every report linked here was issued by DEKRA Testing and Certification (Shanghai) Ltd., an independent testing laboratory. The reports name Blockhütte GmbH in Hamburg, Germany as the client — that is the company that develops our products and commissions the testing.

What the abbreviations mean. FDA 21 CFR 177.1210 is the US Food and Drug Administration rule for the parts that seal a food container, and GRAS covers substances generally recognized as safe. CPSIA is the US Consumer Product Safety Improvement Act of 2008; the reports cover total lead under section 101 and phthalates under 16 CFR 1307. Washington CSPA is the Children's Safe Products Act of Washington State, which sets a cadmium limit. LFGB is the German food and feed code, the European food contact standard — it adds sensory testing, overall migration and heavy metal release, so we publish it alongside the US reports. REACH is the European chemicals regulation, which we use for the silicone and metal parts that are not in food contact.

What is not on this page. Our European stores also publish declarations of conformity under Regulation (EC) No 1935/2004. That is a European instrument with no US counterpart, so it is not reproduced here. If you need it — for a school, a workplace or a procurement file — write to us and we will send it.

A test report stays meaningful for as long as the materials, the suppliers and the construction stay unchanged. Our products are retested every year; the current reports are dated July 22, 2026. If you have a question about any document on this page, write to our support team.
