Is investing in a company that trades in clothes and jewelry, receives funds from investors, distributes 10% of the profits to the company and 90% to investors based on the capital ratio, with a 1% registration fee, and no investment contract for small amounts, considered permissible (halal) or impermissible (haram)?

It is not possible to definitively rule on investing in this specific company. However, in general, there is no objection to investing with companies that operate in permissible trade and regulate their relationship with investors according to a Shariah-compliant Mudarabah contract. Among the conditions for a Shariah-compliant Mudarabah is that the investor's profit should not be a percentage of the capital, but rather a known share of the profit.

What the questioner mentioned about the company requesting a 1% fee upon registration has no known Shariah basis; rather, it is a form of consuming wealth unjustly and invalidates the Mudarabah, because it is not permissible for the Mudarib to take a fixed amount of money along with his share of the profit.

Caution must be exercised regarding fraudulent companies, which are numerous and widespread. Among their signs are high profits in a short period and reliance on registration fees and funds flowing from new investors to pay fictitious profits to earlier ones.
