UAE 12-Digit HS Codes in 2026: What Changed and What Sellers Do Now
If you import into the UAE, the customs tariff code on your declaration is getting longer. The country is moving from 8-digit to 12-digit Harmonized System codes, and the change is already partly in force. The detail that trips people up is that it is not a single switch-on date: it is a phased rollout, and what is mandatory today depends on where your goods are going.
Answer summary
The UAE is moving from 8-digit to 12-digit customs tariff codes under Dubai Customs Notice 10/2025. The rollout is phased, not a single deadline. Since 1 February 2026, 12-digit codes are mandatory for GCC-destined trade and for imports from free zones and customs warehouses into the mainland. Rest-of-world imports follow in August 2026. Goods staying inside a free zone, plus transit and transshipment, keep 8-digit codes.
What actually changed
A UAE customs code used to be 8 digits. It is now 12. The structure stacks three layers: the first 6 digits are the international WCO Harmonized System code, the next 2 are the GCC regional extension (together these are the old 8-digit code), and the final 4 are a new UAE national classification. In practice an existing code gains four trailing digits, so 85171300 becomes 85171300 0000 and then resolves to a more specific national line.
The tariff itself expanded from about 7,809 lines to 13,450. Of those, 951 are newly inserted, 6,518 are subdivisions of old lines, and the rest are unchanged with zeros appended. The expansion buys granularity. A code that used to cover a broad category now splits into several, so the duty and the paperwork attach to a narrower description, and that narrower line is what decides whether your shipment clears under the low-value duty threshold or gets charged in full.
This is Dubai Customs Notice 10/2025, issued in July 2025, implementing Cabinet Resolution 119 of 2024 and the GCC Integrated Customs Tariff on WCO HS 2022.
The phased timeline, and what is in force now
The rollout runs in phases, and getting this wrong is the most common mistake we see:
- Phase 1 (August 2025 to February 2026): flexibility. Traders could use either 8 or 12 digits on GCC trade.
- Phase 2 (from 1 February 2026): the flexibility ends. 12-digit codes are mandatory for GCC-destined trade and for imports moving from free zones and customs warehouses into the local mainland market. This is the phase in force now.
- Phase 3 (from August 2026): the mandate expands to rest-of-world imports into the local market and the GCC.
- Phase 4 (from February 2027): temporary flows destined for the GCC.
Some flows stay on 8-digit codes for now: shipments into a free zone, transit, transshipment, free-zone-to-free-zone moves, and local exports to the rest of the world. So a seller bringing stock into a JAFZA warehouse and holding it there is still on 8-digit until those goods clear into the mainland.
What happens if the code is wrong
A wrong or outdated code costs you at the border. Expect clearance delays while the declaration is queried, reclassification by customs, fines, and retroactive duty if the corrected code carries a higher rate. For a seller running on margin, a shipment held at the border is the expensive part, not the fine, and a mismatched code is one of the things that put a shipment into a customs hold instead of through it.
How to get the code right
Look the code up at the source, not on a forum. Dubai Customs publishes an HS Code Search (Al Munassiq), Dubai Trade exposes the tariff through Mirsal 2, and the Federal Customs Authority maintains the Unified Customs Tariff. Confirm the 12-digit line for each SKU before you ship. Keep a record of which code maps to which product, so a rebuild is not a fresh research project every quarter.
When a 3PL handles it for you
Classification is part of customs clearance, and clearance is bundled into every freight lane our 3PL service in Dubai runs. When we move your stock from China into our Dubai warehouse, the customs clearance is handled on arrival, codes included, so the 12-digit transition is our problem to track, not yours.
Frequently asked questions
Are 12-digit HS codes mandatory in the UAE now?
Partly. Since 1 February 2026 they are mandatory for GCC-destined trade and for imports from free zones and customs warehouses into the mainland. Rest-of-world imports into the local market and the GCC become mandatory in August 2026. Free-zone-bound and transit flows stay on 8-digit for now.
What is the structure of a 12-digit code?
Six international WCO HS digits, two GCC regional digits (the old 8-digit code), and four new UAE national digits.
Where do I look up a 12-digit code?
Dubai Customs HS Code Search (Al Munassiq), Dubai Trade via Mirsal 2, or the Federal Customs Authority Unified Customs Tariff. Confirm at the source rather than copying a figure from a blog.
What happens if I use an old 8-digit code where 12 is required?
Expect clearance delays, possible reclassification, fines, and retroactive duty if the correct code carries a higher rate. The code sets the duty rate, which is the variable that drives how your landed cost and import VAT come out.
Do I need to do this myself if a 3PL clears my goods?
No. Classification is part of the customs clearance your freight provider runs. SamVertex handles it inside the freight lane.
