Air Freight from China to Seria, Brunei — Transit, Duty and Clearance
China → Seria · via BWN air / Muara sea · clearance by Royal Customs and Excise Department

For buyers shipping into Seria, the practical question is not the ocean or flight time but what happens after arrival. Seria is energy sector base; cargo enters through BWN air / Muara sea, and allow +1 day for the inland leg on top of clearance.
The clearing authority is Royal Customs and Excise Department. Historical dwell on this gateway is around 2–5 days, and it lengthens in Sep–Nov.
How this lane actually runs
Brunei is a small-volume market usually served by transshipment through Singapore, Kota Kinabalu or Muara feeder services. Direct China calls are rare, so realistic transit planning should assume one transshipment and a feeder window.

Duty, tax and clearance into Seria
Royal Customs and Excise Department assesses duty and tax on cargo arriving for Seria consignees. Current regime: No VAT or GST; duty 0–20% depending on commodity; excise on selected goods, with a de-minimis position of BND 400 on personal consignments.
Conformity is the part most first-time importers underestimate: Halal certification for food; AITI approval for radio equipment. Getting this wrong is expensive because it usually cannot be fixed after the cargo has landed.
Restrictions and known friction points for Brunei: Alcohol imports are prohibited for Muslim consignees and tightly controlled generally. Halal rules apply to a wide range of food and ingredient imports.

What to sort out before the cargo leaves China
- Check the de-minimis position (BND 400 on personal consignments) against your invoice value before you decide how to split the shipment.
- Book earlier than the transit time suggests during Sep–Nov, when space on this lane tightens.
- Compare gross weight against volumetric weight (L×W×H ÷ 6000) — the higher figure is what gets billed on air and express.
- Ask for the HS code in writing from your supplier and verify the Brunei duty rate against it yourself.
- Get the conformity paperwork moving early: Halal certification for food; AITI approval for radio equipment.
- Declare lithium batteries, magnets, liquids and powders up front — retro-declaring after booking usually means re-planning the whole shipment.
