wp_terms AS terms,
wp_term_relationships AS term_relationships,
wp_term_taxonomy AS term_taxonomy
WHERE term_relationships.object_id = posts.ID
AND term_taxonomy.term_id = terms.term_id
AND term_taxonomy.term_taxonomy_id = term_relationships.term_taxonomy_id
AND posts.post_type = 'product'
AND posts.post_status = 'publish'
AND term_taxonomy.taxonomy = 'product_tag'
AND terms.slug = 'my-tag-1'; -- Replace it with your product tag
