  This paper is a follow-up to (arXiv:2203.03687), in which the first author
studied primitive association schemes lying between a tensor power
$\mathcal{T}_m^d$ of the trivial association scheme and the Hamming scheme
$\mathcal{H}(m,d)$. A question which arose naturally in that study was whether
all primitive fusions of $\mathcal{T}_m^d$ lie between
$\mathcal{T}_{m^e}^{d/e}$ and $\mathcal{H}(m^d, d/e)$ for some $e \mid d$. This
note answers this question positively provided that $m$ is large enough. We
similarly classify primitive fusions of the $d$th tensor power of a Johnson
scheme on $\binom{m}{k}$ points provided $m$ is large enough in terms of $k$
and $d$.
