ISPM-15 Heat Treated Pallets
Gruber Pallets manufactures ISPM-15 certified heat treated pallets at our facility in Lake Elmo, Minnesota. Every heat treated pallet we produce meets international phytosanitary standards — heated to a minimum core temperature of 56°C (132.8°F) for at least 30 minutes. Each pallet is stamped with the official IPPC/ISPM-15 mark, confirming compliance for international shipping.
Whether you're exporting goods to Canada, Mexico, the EU, or anywhere overseas, our heat treated pallets ensure your shipments clear customs without delays. We supply businesses across the Twin Cities metro, Greater Minnesota, and western Wisconsin with reliable HT pallets in standard 48×40 GMA sizes as well as custom dimensions.
Why Heat Treated Pallets?
Export compliance: Since 2005, ISPM-15 regulations require all wood packaging materials used in international trade to be heat treated or debarked. Non-compliant pallets can be rejected at the port, causing costly delays and re-shipment fees.
Pest-free guarantee: Heat treatment eliminates insects, larvae, and pathogens in the wood — no chemicals involved. This makes HT pallets safer for food, pharmaceutical, and agricultural shipments.
Domestic use too: Many domestic customers choose heat treated pallets for food-grade applications, cleanroom environments, and any operation where chemical-free wood packaging matters.
New heat treated pallets are available as low as $14, with volume discounts available for larger orders. Call (651) 436-1912 for competitive pricing.
Common Questions
What is ISPM-15?
ISPM-15 (International Standards for Phytosanitary Measures No. 15) is a regulation that requires wood packaging materials used in international trade to be treated to prevent the spread of invasive pests. Heat treatment is the most common and environmentally friendly method.
How do I know if my pallets are ISPM-15 compliant?
Every compliant pallet carries an official IPPC stamp showing the treatment method (HT for heat treated), the country code (US), and the producer number. All Gruber Pallets heat treated pallets are properly stamped and certified.
Do I need heat treated pallets for shipping to Canada?
Yes. Canada requires ISPM-15 compliant wood packaging for all imports. This includes pallets, crates, and dunnage. We supply many Minnesota businesses that ship regularly across the border.
What sizes of heat treated pallets do you offer?
We produce standard 48×40 GMA pallets as well as custom sizes. Whether you need a standard stringer pallet or a specialized block pallet, we can heat treat it to ISPM-15 standards. Call (651) 436-1912 or request a quote for custom dimensions.
How quickly can you deliver heat treated pallets?
We keep heat treated pallets in stock at our Lake Elmo facility and can deliver throughout the Twin Cities metro within 1–2 business days. Larger custom orders typically ship within 3–5 business days.
