1) When you request export-ready pallets or crates
- Your order is flagged EXPORT / ISPM-15 in our system and routed to a segregated workflow.
- Any repaired units are automatically queued for re-treatment and re-marking (ISPM-15 rules for repaired WPM).
- Domestic-only SKUs remain on a separate path to avoid cross-contamination.
2) Heat treatment run (HT: 56 °C × 30 min, wood core)
- Load build: Pallets/crates are stacked to allow airflow; temperature probes are inserted into representative pieces at the wood core.
- Cycle control: The chamber runs until every probe reaches ≥ 56 °C and holds for 30 minutes.
- Calibration & logs: Probe IDs, time–temperature curves, chamber ID, operator and cycle start/stop times are saved against your batch.
3) Post-treatment handling & segregation
- Treated lots move to a clearly marked, export-only holding area; domestic stock never mixes here.
- Operators perform a quick visual QC: debarked wood (DB), fastener seating, no green/condensing moisture.
4) The ISPM-15 mark (what you’ll see on the pallet/crate)
Each treated item is marked with an IPPC/ISPM-15 stamp. It typically appears on two opposite sides of the pallet stringer or crate member and contains:
┌───────────── IPPC wheat symbol ─────────────┐
│ SG-1234 DB-HT │
│ (Country) (Producer/Facility)-(Treatment)│
└──────────────────────────────────────────────┘
- Country code: e.g., SG, MY
- Facility number: our registered treatment facility ID
- Treatment code: HT (heat treatment) or MB (methyl bromide fumigation, where permitted)
- DB: debarked (required notation)
For repaired pallets, the final treating facility’s mark must be present after re-treatment. You may see legacy marks from the pallet’s earlier life; that’s normal, but the most recent mark is the controlling one.
5) Your documentation pack (what you receive)
- Treatment Certificate (PDF): customer name, PO, batch ID, cycle date/time, chamber ID, operator, probe count, 56 °C/30-min compliance statement.
- Traceability Sheet: SKU list, quantities, mark pattern, and any repair work performed.
- Optional attachments: probe charts or summary logs, if your QA needs them for vendor audits.
- Labeling: outer pack labels noting “ISPM-15 HT”, batch ID, and piece count to speed goods-in checks.
6) At your warehouse / at customs (how it speeds you up)
- Goods-in: Your team verifies the stamp on two sides and matches the batch ID to the Treatment Certificate—no need to open every unit.
- Export & inspections: The ISPM-15 stamp is the authority; many jurisdictions don’t require the certificate to travel, but carrying it helps resolve inspections quickly.
- Mixed shipments: Export-ready lots ship separately from domestic pallets to prevent accidental substitutions.
7) Common edge cases we manage for you
- Composite materials: Plywood, OSB, MDF and other processed wood components are already exempt under ISPM-15 but we still mark crates externally if any solid-wood members are present.
- Moisture & mold risk: If post-treatment moisture is borderline for your route, we extend dry-down or use spacers to reduce condensation risk.
- Repaired pallets: If > 1/3 of components are replaced, ISPM-15 requires re-treatment and re-marking—our workflow enforces this automatically.
- Route-specific preferences: Some customers prefer HT only (no MB) due to internal policies; we’ll lock this at the customer profile level.
8) Quick export-readiness checklist (you can place this as a sidebar)
- ISPM-15 DB-HT stamp on two sides, legible
- Batch ID matches your paperwork
- Treatment Certificate on file (digital)
- Packaging labels show ISPM-15 HT and quantities
- Domestic and export lots not mixed on the same pallet
- Optional: attach probe summary for QA-heavy clients
