Quick Answer
When Thailand Post issues a Green Form notice, your parcel is being held for tax assessment, value proof, or permit review. Most cases can be resolved quickly by presenting ID plus matching payment evidence at the designated postal customs office.

Why did I get a Green Form?
In 2026, Green Forms appear more often because low-value parcels are reviewed under expanded tax treatment. Three reasons explain most notices.
- Tax assessment (Category 2): duty and VAT are assessed and waiting for payment.
- Value verification (Category 3): officers need real payment proof when declared value looks unclear.
- Permit requirement: goods fall under controlled categories and need regulator release support before customs can release the parcel.
3 steps to get your package released
- Prepare real transaction evidence: bring bank, card, or wallet payment proof, not only order confirmation pages.
- Decide who appears at the counter: go in person or assign a representative using the authorization section and signed ID copy.
- Pay the assessed bill at the designated counter and keep the receipt until parcel handover is complete.
What should you bring to the postal customs counter?
Bring one complete document set in print or clear digital form. Incomplete files are the main reason same-day pickup fails.
- Original Green Form notice and valid government ID.
- Invoice or order details matching the tracking number.
- Actual payment evidence from bank, card statement, or e-wallet transfer.
- Any permit or release note if item category is regulated.
How do you avoid repeat Green Form delays?
- Use specific product descriptions before checkout and shipment dispatch.
- Keep proof of purchase and payment in one folder for fast retrieval.
- Avoid undervalued declarations that conflict with actual transfer amount.
- Check permit-sensitive categories before ordering high-risk items.
How should recipients and senders communicate during a hold?
Use one clear message thread covering tracking number, requested document, and payment status. This prevents duplicate submissions and conflicting explanations.
- State whether the issue is tax payment, value proof, or permit approval.
- Send the same finalized invoice and payment file to all involved parties.
- Confirm who will appear at the counter and when.
- Notify sender and recipient once parcel is released and collected.
Case example: value proof released a held parcel
A recipient received a Green Form for imported electronics and first submitted only an order screenshot. Customs asked again for actual payment transfer proof. After submitting matching bank evidence and ID documents in one visit, tax was paid at the counter and the parcel was released the same day.
