ISPM 15 Certification in Sri Lanka: A Complete Guide for Exporters

What ISPM 15 Actually Requires

ISPM 15 — International Standards for Phytosanitary Measures No. 15 — is the global standard governing wood packaging material in international trade. It exists because untreated wooden pallets, crates, and dunnage have historically been a major pathway for the spread of wood-boring pests between countries. Any solid wood packaging thicker than 6mm that crosses an international border must be treated according to the standard and must carry the IPPC certification mark.

The standard permits two main treatment methods: heat treatment (HT), in which the core of the wood is raised to a minimum of 56°C and held there for at least 30 minutes, and methyl bromide fumigation (MB), which is being phased out in most markets due to environmental concerns. In Sri Lanka, heat treatment is the standard method, and it is the only method we recommend — HT-marked packaging is accepted everywhere, while MB-marked packaging faces restrictions in the EU and a growing list of other markets.

The IPPC Mark: What It Means and Who Can Apply It

The IPPC mark is a standardised stamp applied to certified wood packaging. It contains the IPPC symbol, a two-letter country code (LK for Sri Lanka), a unique registration number identifying the treatment facility, and the treatment code (HT for heat treatment). Customs authorities at destination ports check for this mark — packaging without it, or with an illegible or incomplete mark, is treated as non-compliant.

Only facilities registered with the National Plant Quarantine Service (NPQS) of Sri Lanka may apply the mark. Registration requires the facility to demonstrate that its treatment process reliably achieves the 56°C/30-minute core temperature requirement, with calibrated monitoring equipment and documented procedures. The registration number in the mark is traceable — if a problem is found at a destination port, the shipment can be traced back to the treating facility.

This is the critical point for exporters: you cannot heat-treat packaging yourself, and you cannot buy an IPPC stamp. The mark is only valid when applied by a registered facility on wood that facility actually treated.

What Happens When Packaging Is Non-Compliant

The consequences of shipping with non-compliant wood packaging depend on the destination country, but the typical outcomes are: the shipment is held at port while the packaging is treated or destroyed at the importer's expense; the packaging is rejected and the goods must be re-packed; or in the strictest markets, the entire consignment is refused entry and returned. Australia and New Zealand are known for particularly rigorous enforcement.

Beyond the direct cost, a rejected shipment damages the relationship between exporter and buyer, and repeated non-compliance can flag an exporter for increased inspection on future shipments. For a relatively small treatment cost per pallet or crate, ISPM 15 compliance is among the cheapest insurance an exporter can buy.

The Certification Process, Step by Step

• Send your packaging — pallets, crates, boxes, or loose dunnage — to a registered treatment facility, or have the facility manufacture certified packaging for you.
• The wood is heat treated: loaded into the chamber, brought to 56°C core temperature (verified by probes in the thickest pieces), and held for a minimum of 30 minutes.
• The facility applies the IPPC mark to at least two opposite sides of each item.
• A treatment certificate is issued for the batch, recording the date, treatment parameters, and quantity — keep this with your shipping documents.
• The packaging is ready for export. Note that re-treatment is required if the packaging is repaired with untreated wood at any point.

Common Mistakes That Cost Exporters

The most frequent mistake we see is treating packaging as an afterthought — ordering certified pallets days before a shipment deadline. Heat treatment itself is fast, but chamber scheduling, transport, and marking take time. Build packaging certification into your shipping timeline a week or more ahead.

The second mistake is repairing certified packaging with uncertified wood. A certified pallet repaired with an untreated board is no longer compliant — the whole unit must be re-treated and re-marked. Destination inspectors specifically look for boards without marks on otherwise marked pallets.

The third is confusing kiln drying with ISPM 15 heat treatment. They are different processes with different targets: kiln drying targets moisture content and takes days; ISPM 15 heat treatment targets core temperature and takes hours. Kiln-dried wood is not automatically ISPM 15 compliant — the treatment must be run and documented specifically against the ISPM 15 standard by a registered facility.
