Pallet heat treatment service

We collect your own wooden pallets, crates and packing cases, have them heat treated and marked to ISPM 15, and return them to your site, ready for export.

The core of the wood is held at 56°C for at least 30 minutes, and every item comes back stamped with the IPPC symbol, the producer code and HT.

  • 56°C at the core for at least 30 minutes
  • Marked to ISPM 15 with HT
  • Collected and returned across the UK

What needs treating, the number and the postcode carry into the full form, where you add sizes and the date you need them back.

What does the pallet heat treatment service cover?

The pallet heat treatment service covers your own wooden pallets and your wooden crates and packing cases, the wood packaging that ISPM 15 applies to, according to GOV.UK.

Your wooden pallets

Any size of wooden pallet you already own, from UK standard 1200 x 1000 mm and Euro 1200 x 800 mm to CP and odd sizes.

  • Covered by ISPM 15 as pallets and box pallets
  • Already marked pallets are checked, and returned untreated if the mark is legible and the pallet is unrepaired

Your crates and packing cases

Solid-wood crates, packing cases and the dunnage packed with them.

  • Covered by ISPM 15 as packing cases, crates and dunnage
  • Plywood panels are exempt as processed wood

Bark left on the wood is removed before treatment, as ISPM 15 allows only pieces under 3 cm wide, or wider pieces under 50 cm² in total, according to GOV.UK.

How are pallets heat treated to ISPM 15?

Pallets are heat treated to ISPM 15 in a kiln that holds the core of the wood at 56°C for at least 30 continuous minutes, then stamped with the ISPM 15 mark, according to GOV.UK.

  1. 1
    Debark

    Bark is cut away to the ISPM 15 limit before the wood goes in.

  2. 2
    Load and probe

    A temperature probe goes into the densest piece in the slowest-heating part of the kiln.

  3. 3
    Heat

    The kiln runs until the probe reads 56°C at the core and holds it for 30 minutes.

  4. 4
    Mark

    Each item is stamped with the IPPC symbol, the country code, the producer code and HT, the code for heat treatment.

  5. 5
    Record

    The kiln's temperatures for each run are kept for audit.

Dielectric heating (code DH) is the other heat route, at 60°C for 1 minute through the whole profile, for wood under 20 cm thick (GOV.UK).

The standard behind each step, including the materials it exempts, is set out in our guide ISPM 15 explained. A kiln drying cycle alone does not meet ISPM 15 unless the core reaches 56°C for 30 minutes, according to the Forestry Commission.

How does the heat treatment service work, from collection to return?

The heat treatment service works in three steps. We collect your pallets, have them heat treated and marked, and we return them.

  1. 1
    Send the details

    Tell us what needs treating, how many, the sizes and the postcode; we reply with a price.

  2. 2
    Hand over the items

    We collect them from your site and check the marks they already carry.

  3. 3
    Get them back marked

    They are heat treated and stamped, and we return them with the batch details.

Who can heat treat and mark pallets in the UK?

Only members of the UK Wood Packaging Material Marking Programme who are registered with the Forestry Commission as professional operators heat treat and mark ISPM 15 wood packaging in Great Britain, according to GOV.UK.

Membership
The UK marking programme, with a facility assessment every 6 months
Producer code
The member's own code in the mark, which traces each item back to the treater
The law
No one applies the mark without authority under the Plant Health (Wood Packaging Material Marking) (Forestry) Order 2006

Every item in this service comes back heat treated and carrying the ISPM 15 mark.

Do marked or repaired pallets need heat treating again?

No for marked pallets left as they are, because a pallet with a legible ISPM 15 mark that has not been repaired or rebuilt needs no new treatment, according to the IPPC's text of ISPM 15.

We check the marks first, and pallets that already carry a legible ISPM 15 mark and have not been repaired come back untreated and are left off the price. Pallets mended by our pallet repair service for export go through the same rule.

ISPM 15 heat treatment certificate and paperwork

The ISPM 15 mark is the heat treatment certificate, and wood packaging with a legible mark needs no phytosanitary or treatment certificate, and no certificate replaces the mark, according to GOV.UK.

Empty pallets shipped on their own carry the mark too, and it replaces an export phytosanitary certificate (Defra).

What sets the cost of pallet heat treatment?

Four things set the cost of pallet heat treatment, the number of items, their type and size, the collection and return postcode, and how many already carry a legible mark.

Treat your own pallets or buy heat treated pallets?

Treat your own pallets when you already hold enough sound wooden pallets or crates for the load; buy heat treated pallets when you do not.

DetailTreat your ownBuy heat treated
What you need firstSound wooden pallets or crates on siteNothing; we supply the pallets
What comes backYour own items, markedNew or used pallets, already marked
How to orderBook treatment on this pageOrder from the heat treated pallet range

We also sell heat treated pallets ready marked, in UK standard, Euro, CP and square sizes, on our page for heat treated pallets for export, and heat-treated pallet collars to go with them. Both routes meet the rule for loads from Great Britain to the EU and to Northern Ireland, which need the ISPM 15 mark (GOV.UK). A third route is plastic pallets, exempt from ISPM 15 because the GOV.UK rules cover wood packaging material. New export crates are built to order on our page for wooden crates and packing cases.

Pallet heat treatment FAQs

Is there a pallet heat treatment service near me?

Yes. We collect pallets for heat treatment from sites across the UK and return them marked.

Is kiln drying the same as heat treatment?

No. Kiln drying lowers moisture and sets no minimum temperature; heat treatment holds the core at 56°C for 30 minutes. Only heat treatment earns the HT mark, according to the Forestry Commission.

Do plastic pallets need heat treatment?

No. Plastic pallets are exempt from ISPM 15, because the GOV.UK rules cover wood packaging material and a plastic pallet contains no wood.

How long does pallet heat treatment take?

The kiln hold is at least 30 continuous minutes at 56°C in the core of the wood, counted from when the core reaches that temperature. The full turnaround, collection to return, depends on the number of items and is confirmed with your quote.

Can I heat treat pallets myself?

You heat treat pallets for export yourself only as a registered member of the UK Wood Packaging Material Marking Programme, according to GOV.UK; otherwise the pallet carries no ISPM 15 mark and counts as untreated.
