Importing vacuum flasks into Thailand: TISI licence data must now be on the NSW (2026)

Customs now matches the licence in the system instead of looking at it

Under Thai Customs Notification No. 116/2569, from 13 October 2026 vacuum flasks and their parts can only be declared for import if the TISI (สมอ.) licence data is linked to the National Single Window (NSW). The notification is dated 25 September 2026 and rests on Customs Notification No. 131/2561, which covers data links under other laws.

Two tariff lines are covered.

HS code	Statistical code	Goods	Direction
9617.00.10	000	Vacuum flasks and other vacuum vessels, complete	Import
9617.00.20	000	Parts thereof, other than glass inners	Import

The 0 in the notification's direction column means import (1 is export and 3 is both). These two lines are added to the existing list of linked goods; nothing has been removed.

A licence alone can still leave your shipment stuck

Vacuum vessels were already a mandatory TISI product, so there is no new licence to obtain. The only change is at customs.

That one change works very differently in practice. Before, holding the licence was enough, and a paperwork problem could be fixed at the border. Now the system matches the data. If the licence exists but its data is not on the NSW, the declaration does not go through. No officer is weighing the case, so explaining at the border does not help.

You also find out late. A licence is usually obtained once, when imports start, and rarely checked again. A mismatch gives no warning in normal times, and the first sign is the day the vessel arrives and the declaration is filed. By then the warehouse slot and the marketplace stock plan already depend on that shipment.

The party that carries this is the importer, not the manufacturer. Both the licence and the NSW record sit in the importer's name, and demurrage and delay costs land there too. If you sell into Thailand without a local entity, the first question is who holds that importer seat and whether they know about this notification.

Four checks before the next shipment

• Does the scope of the TISI licence cover every model you actually ship? New models on an unchanged licence are the most common gap.
• Is that licence data registered on the NSW? Holding a licence and having it on the system are separate things.
• Does your customs broker know about the notification? If not, the first declaration will be rejected.
• Parts are covered except glass inners. If you ship glass inners alone, or mix complete flasks and parts in one declaration, sort out the classification first.

If the importer seat is empty

Home and living is the largest category by units sold on Shopee Thailand (20%, Momentum Works 2023), and vacuum flasks sit right in it. The constraint is not demand but one line of customs data.
