What the stamp should show
The mark is a bordered box with the IPPC symbol on the left. To its right: PL, a hyphen, the code Main Inspectorate of Plant Health and Seed Inspection Service 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 Poland rather than against a fixed pattern.
IPPC | PL-[producer code] | HT (layout only; the producer code is a placeholder)

On arrival in the US or Canada
Wood packaging from Poland 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 Poland are yours to reuse, sell or recycle, unless they belong to a rental pool.
