Fumigation certificate
— definition for Pakistani agri exporters.

Definition

A fumigation certificate is the formal document issued by a licensed fumigation contractor (and counter-signed where required by the National Plant Protection Organization) confirming that an export consignment, its packaging, and/or any solid wood packaging material accompanying it has been treated with an approved fumigant — most commonly methyl bromide (MeBr) or phosphine (aluminium / magnesium phosphide) — at a defined dosage, temperature, exposure time and concentration sufficient to kill the regulated quarantine pests.

Wood-packaging fumigation against ISPM 15 is a separate but related regime: solid wood pallets and dunnage carry the visible IPPC mark with a country code, registered facility number and treatment code (HT for heat treatment or MB for methyl bromide).

Why it matters for Pakistani exporters

For Pakistani agri exporters, fumigation is effectively mandatory: most importing countries (Bangladesh, Sri Lanka, Indonesia, Philippines, EU, USA, Australia) require fumigation against khapra beetle, weevils, moths and stored-product insects on cumin, fenugreek, fennel, coriander, chilli, sesame, pulses and similar dry commodities. Skipping fumigation results in port-side rejection, re-fumigation at destination at higher cost, or in worst cases destruction.

The fumigation certificate is also a prerequisite for the phytosanitary certificate in many DPP workflows — the Pakistani Department of Plant Protection inspector typically inspects after fumigation has occurred and the certificate is on file.

Practical guidance

Standard fumigation parameters for Pakistani spice and seed exports:

• Methyl bromide (MeBr): dose typically 32 g/m³ at temperatures > 21°C, exposure 24 hours, with concentration readings at 0.5h and 24h. Used widely but being phased out under the Montreal Protocol — increasingly restricted.
• Aluminium phosphide / phosphine (PH₃): dose 2-3 g/m³ over 5-7 days at > 25°C — slower, gentler on commodity, increasingly preferred.
• Heat treatment (HT) for wood packaging only — core temperature ≥ 56°C for ≥ 30 minutes, marked HT.

Fumigation can be performed in-container at the stuffing point, in a fumigation chamber, or in stack under tarpaulin in the warehouse. The certificate records contractor license, fumigant, dose, duration, container number and a signed attestation that aeration is complete and the cargo is safe to release.
