Quick Answer
A postal customs notice tells you what action is needed and where to take it. Read the instructions before visiting: the next step may involve duties and taxes, purchase evidence or further clearance requirements.
This guide covers Thailand Post notices. Check the operator named on your notice before following the postal collection steps.
If your notice is from FedEx, DHL or UPS for a shipment held at Suvarnabhumi, use our courier clearance service page for the relevant documents and fees.
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.
- Duties and taxes: the notice specifies the amount assessed and where to pay or collect the parcel.
- Value verification: Customs may request purchase and payment evidence to review the declared value.
- Further clearance: some goods require additional formalities or product approvals. Follow the instructions on the notice.
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?
Check the notice for the required documents and whether originals are needed. Prepare matching copies and payment evidence before visiting the named office.
- 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.
Example: matching payment evidence to the invoice
For example, if Customs asks for proof of an electronics purchase, an order screenshot may not show the amount actually paid. Provide the matching bank or card payment record alongside the invoice. This is an illustrative document example; the release timing depends on the outstanding requirements.
