Fumigation & export packing standards
ISPM-15 wood packaging requirements, when fumigation certificates are needed, packing list accuracy rules, and special cargo markings — everything an Indian exporter needs to know.
What is ISPM-15?
ISPM-15 (International Standards for Phytosanitary Measures No. 15) is a global standard set by the International Plant Protection Convention (IPPC). It requires that wooden packaging material used in international trade is treated to kill plant pests, insects, and fungi that could hitch a ride in raw wood.
Think of it this way: a wooden pallet carries not just your goods, but potentially the insects and diseases living in the wood. ISPM-15 ensures that wood is treated before it crosses a border, preventing agricultural disasters in the importing country.
If you skip ISPM-15:
- • Destination customs can seize and destroy your wooden packaging
- • Your goods may be re-exported at your cost
- • In Australia and USA, fines can exceed $10,000 USD
- • Your buyer loses confidence and may cancel future orders
The ISPM-15 Mark (what it looks like)
IN - 123 - MF456
HT · 24
IPPC logo · Country code (IN = India) · Producer ID · Treatment facility ID · Treatment code (HT/MB) · Year
This mark must be burned or stamped (not painted) on all treated wood. It is non-transferable.
What requires ISPM-15 treatment?
| Item | Treatment required? | Notes |
|---|---|---|
| Wooden pallets (solid wood) | Required | Most common item — almost always used for sea/air shipments |
| Wooden crates and boxes | Required | Any solid wood structure used to protect/contain cargo |
| Dunnage (wood packing/bracing) | Required | Scrap wood used to fill gaps and prevent cargo shift |
| Wooden cable reels / spools | Required | Used for cables, wires, textile rolls |
| Plywood (manufactured boards) | Exempt | Plywood, OSB, chipboard — manufactured panels are generally EXEMPT |
| Cardboard/paper packaging | Exempt | No ISPM-15 requirement |
| Plastic pallets / crates | Exempt | No ISPM-15 requirement — increasingly used for this reason |
| Metal frames / containers | Exempt | No ISPM-15 requirement |
| Bamboo packaging | Exempt | Bamboo is technically grass — exempt in most countries (verify per destination) |
ISPM-15 treatment methods
There are several approved treatment methods. The method used is stamped on the mark (HT, MB, DH, SF). Most Indian exporters use HT (heat treatment).
Heat Treatment
HTWood heated to 56°C core temperature for 30 minutes. No chemicals — most widely accepted globally.
Accepted in: USA, EU, Australia, Canada, Japan, China, Most countries
Wood must be treated in a facility approved by NPPO (National Plant Protection Organisation). In India: NPPO-India under APEDA.
Methyl Bromide Fumigation
MBChemical fumigation with methyl bromide at prescribed concentration and exposure time.
Accepted in: Most countries (limited)
Being phased out globally due to ozone depletion. EU banned for most uses. Australia, USA, China still accept. Check destination country rules.
Dielectric Heating
DHUses radio frequency electromagnetic fields to heat wood. Less common but ISPM-15 compliant.
Accepted in: Select countries
Used for specialty wood items. Rapid but requires specific equipment.
Sulfuryl Fluoride
SFChemical fumigation alternative to MB. Accepted in USA and some other countries.
Accepted in: USA, Canada, Some others
Check specific country acceptability. Not universally adopted as an ISPM-15 treatment.
When is a separate Fumigation Certificate needed?
ISPM-15 treatment of wooden packaging is NOT the same as a fumigation certificate for the cargo itself. A fumigation certificate is a separate document issued after the goods (not the wood) are fumigated.
When fumigation of CARGO is required:
- Cereals, grains, rice (wheat, maize, etc.) — Australia, USA, EU require fumigation
- Tobacco and tobacco products — many countries require
- Raw cotton, hessian bags — some Middle East countries
- Spices (whole) — some countries require phytosanitary certificate + fumigation
- Any organic/agricultural product going to Australia — strict biosecurity laws
- Container fumigation — some buyers / destination ports require the container itself to be fumigated
What the fumigation certificate contains:
- Name of fumigant used (Methyl Bromide, Aluminium Phosphide, etc.)
- Concentration (g/m³) and exposure time
- Date and location of fumigation
- Container number or description of cargo treated
- Name and registration of licensed fumigation company
- Signature of licensed fumigator
Important: After fumigation, the container must air out for the prescribed period before workers enter. Fumigation certificates must be presented to the shipping line before loading. Ambeza coordinates this with licensed fumigators.
General export packaging rules
Beyond ISPM-15, every export carton and crate must meet these standards. Incorrect packaging is one of the most common reasons for insurance claims being rejected.
Gross weight on outer carton
Every outer carton must have net and gross weight marked. Common mistakes: writing kg instead of kgs, or omitting.
Number of units
e.g. 'Box 1 of 24' — helps customs count packages and matches Packing List.
Country of origin
'Made in India' — mandatory on all export goods. Placement: visible face of each carton.
HSN/HS code on commercial invoice
Not on outer carton, but invoice and Packing List must match. Mismatch = customs query.
Consignee details on label
Full consignee name, address, destination country. Required for customs to match with Shipping Bill.
Batch number / lot number
Required for pharma, food, chemicals. Must match Certificate of Analysis and invoice.
Packing List accuracy
If the packing list says 24 cartons of 20 pieces each = 480 pieces total, but actual count differs, customs will hold the shipment.

Wrong or missing DG labels = cargo rejection at port, heavy fines

Regulation
No formal regulation — shipper's responsibility but insurers may reject damage claims without markings
No specific regulatory warning for this cargo type — follow shipper best practices.
Perishables / Food

ISPM-15 wood packaging
Required markings
- ISPM-15 stamp: IPPC logo, Country code (IN), Producer/treatment facility ID, Treatment method code (HT or MB), YY (year)
Regulation
ISPM-15 — International Standards for Phytosanitary Measures No. 15
Without valid ISPM-15 mark, wooden packaging can be seized and destroyed by destination country
Packing List accuracy warning
Your Packing List must exactly match the physical cargo. Any discrepancy between the Packing List, Commercial Invoice, and actual physical count/weight triggers a customs examination — and can result in:
- Shipment hold for physical examination (adds 3–7 days)
- Misdeclaration penalty under Customs Act, 1962
- IGST refund delays if weight/value doesn't match
- Buyer disputes if actual goods don't match invoice
Always have your warehouse team count, weigh, and verify before the packing list is finalised. Ambeza cross-checks all documents before filing.
