Charles Ellicott Commentary Exodus 30:9

"Ye shall offer no strange incense thereon, nor burnt-offering, nor meal-offering; and ye shall pour no drink-offering thereon." — Exodus 30:9 (ASV)

You shall offer no strange incense. —By “strange incense” is meant any that was composed differently from that whose composition is prescribed in Exodus 30:34-35.

Nor burnt sacrifice, nor meat offering; neither ... drink offering. —All these were to be offered on the brazen altar, not on the altar of incense, which was in no way suited for them.
