What we offer

Four ways we keep cargo moving.

[ edi terminal · customs office ]

IMP

Import clearance

Full import declaration, duty calculation, permit handling, and release coordination at every major Thai port and airport.

EXP

Export clearance

Export declaration, certificate of origin, and license verification — filed in advance so vessel and flight cut-offs are never missed.

REX

Re-export & bonded

Bonded warehouse handling, re-export filings, and free zone movements — for goods that arrive but don't stay.

Tariff & advisory

HS code classification, duty rate analysis, and pre-import advisory so your landed cost is known before the goods leave origin.

Process

Three stages from arrival to release.

Pre-arrival preparation

We review your documents, classify the goods, calculate duties and taxes, and prepare the declaration before the cargo lands.

eDI Submission

Electronic data interchange straight to Thai Customs Department via the National Single Window — no paper, no queues, no delay.

Inspection & Release

We attend any physical inspection, settle duties and taxes, and coordinate release from the port or airport warehouse to your nominated transport.

Why KNS Plus for customs

Files that clear without callback.

Licensed under DBD #24, #25, #27

Authorised by Thailand's Department of Business Development to act as your customs agent — on the record, on the file.

Direct eDI submission

We file electronically into the Customs Department system. No third-party broker, no delay, no telephone-game versions of your data.

Tariff judgement, not guesswork

Correct HS codes the first time mean correct duty, no reclassification, and no expensive arguments at release.
