What the stamp should show
The mark is a bordered box with the IPPC symbol on the left. To its right: SK, a hyphen, the code Ústredný kontrolný a skúšobný ústav poľnohospodársky v Bratislave (UKSUP) gave the producer or treatment provider, and the treatment code. Producer code formats differ by country, so check the shape of the code against other marks from Slovakia rather than against a fixed pattern.
IPPC | SK-[producer code] | HT (layout only; the producer code is a placeholder)
Who authorises the mark in Slovakia
The IPPC country page for Slovakia lists the official contact point as Ústredný kontrolný a skúšobný ústav poľnohospodársky v Bratislave (UKSUP), registered on 12 Jan 2021. That body, or the agency it delegates to, registers treatment providers and producers and polices use of the mark. Open the IPPC page for Slovakia for current contact details.

On arrival in the US or Canada
Wood packaging from Slovakia entering the United States is regulated under 7 CFR 319.40-3; entering Canada, under CFIA directive D-98-08. Both rely on the ISPM 15 treatment and mark. Once the goods are unpacked, surplus pallets from Slovakia are yours to reuse, sell or recycle, unless they belong to a rental pool.
