Which document you need and why
National Order 435 certification for covered 2520, 2522 and 2523 products
Cements, building lime and gypsum binders in these headings are included in Appendix 4’s mandatory certification list. The document concerns the specific binder; an industrial chemical reagent, ready-made plaster mix or gypsum article needs separate identification and is not automatically covered by a raw-material certificate. Cement assessment also follows the national cement and clinker conformity procedure referenced by the regulation and the evidence required by the selected scheme.
