Uncertified Lotus Biscoff Cookies

According to the company website:

Lotus Biscoff Products are not Kosher certified.

From Kosher.com:

Note: Biscoff brand products, including Lotus Cookies, that are made in Belgium and are imported and sold in the US and Europe do not have a hechsher (kosher certification). Biscoff brand products that are produced for Israeli distribution are kosher and do have a hechsher in many kosher food stores around the world as an import from Israel. Please check products carefully for kosher certification before purchase.

The ingredients panel, however, lists only:

Wheat Flour, Sugar, Vegetable Oils (contains one or more of soy bean oil, sunflower oil, canola oil, palm oil), Brown Sugar syrup, sodium bicarbonate (Leavening), Soy Flour, Salt, cinnamon

What would/could be the concern with uncertified packages? What might the kosher-certifying agency be doing different in the “kosher runs” of the cookie?

The OU claims that there are general concerns with vegetable oils of cross contamination: https://oukosher.org/blog/consumer-kosher/kosher-oils/

Is that really a halachic concern nowadays for such a product?

Thanks.

Kosher. No worries.

OU and others are just protecting their business.
