In the case of hop powder, hop powder with higher lupulin content, extract of hops and mixed hop products, the attestation may be recognised as being equivalent to the certificate only if the alpha acid content of those products is not lower than that of the hops from which they have been prepared.
Humalapulbri, suurema lupuliinisisaldusega humalapulbri, humalaekstrakti ja segatud humalatoodete puhul võib tõendi samaväärseks tunnistada üksnes juhul, kui kõnealuste toodete alfahappesisaldus ei ole madalam kui nende valmistamiseks kasutatud humala alfahappesisaldus.
