Shipping from China to Chiang Mai, Thailand — Freight Guide [2026]
China → Chiang Mai · via CNX air / Laem Chabang sea · clearance by Thai Customs Department (กรมศุลกากร)

Chiang Mai is northern commercial centre, handicraft and agri-processing base, and it is served through CNX air / Laem Chabang sea. That combination is what actually sets your delivery date on this lane — allow +2 days for the inland leg on top of clearance.
Clearance itself is handled by Thai Customs Department (กรมศุลกากร), and typical dwell at the gateway runs 2–5 days.
Import duty and tax position for Chiang Mai
Thai Customs Department (กรมศุลกากร) assesses duty and tax on cargo arriving for Chiang Mai consignees. Current regime: VAT 7%; duty 0–30%, and 0% on most lines with an ACFTA Form E, with a de-minimis position of THB 1,500 (VAT now applies to low-value imports).
Conformity is the part most first-time importers underestimate: TISI standard mark for regulated goods; NBTC approval for radio devices; Thai FDA for food, cosmetics and supplements. Getting this wrong is expensive because it usually cannot be fixed after the cargo has landed.
Restrictions and known friction points for Thailand: Cosmetics, supplements and food need Thai FDA registration held by the consignee before arrival. Used machinery, secondhand goods and e-cigarettes are restricted or banned. Batteries move on approved air channels only.
What the routing looks like in practice
Thailand is a short-haul lane: Shenzhen and Guangzhou both run daily air departures into Suvarnabhumi, and Laem Chabang is only 5–9 days from Shekou or Nansha. A land option also exists via the R3A road corridor through Laos, which is sometimes cheaper than air for semi-urgent cargo.

Pre-shipment checklist for Chiang Mai
- Get the conformity paperwork moving early: TISI standard mark for regulated goods; NBTC approval for radio devices; Thai FDA for food, cosmetics and supplements.
- Ask for the HS code in writing from your supplier and verify the Thailand duty rate against it yourself.
- Confirm the consignee in Chiang Mai can act as importer of record — Thai Customs Department (กรมศุลกากร) will not release cargo to an unregistered party.
- Book earlier than the transit time suggests during Sep–Nov, when space on this lane tightens.
- Photograph carton markings and seal numbers before departure — it makes any claim far easier to settle.
- Use ISPM-15 treated pallets. Untreated wood is the most common reason otherwise-clean cargo gets held.

A commercial invoice with HS codes, a packing list, the bill of lading or air waybill, a certificate of origin where it lowers duty, and any product certification (TISI standard mark for regulated goods; NBTC approval for radio devices; Thai FDA for food, cosmetics and supplements). We prepare and file these as part of the service.
How is the chargeable weight calculated for Chiang Mai?
We compare actual gross weight against volumetric weight — length × width × height in centimetres divided by 6000 for air — and bill the greater of the two, rounded up to the next kilogram. Light, bulky cargo is almost always billed on volume.
