Jebel Ali customs treats lithium-ion ESS shipments as Class 9 dangerous goods — verify the UN38.3 test summary, the IEC 62619 report, and the correct shipping mark before you sign the purchase order.

· July 2026 · 8 min read

Before signing a purchase order for a lithium-ion energy storage system bound for the UAE, buyers need three documents confirmed in advance: a signed UN38.3 test summary, an IEC 62619 report covering the assembled battery rack, and the correct Class 9 dangerous goods shipping mark. Jebel Ali customs treats these ESS units as Class 9 hazardous cargo, and a cell-level-only report is a common reason containers get held at the port. This checklist covers what to verify and what to ask your supplier first.

Why Jebel Ali Customs Treats a Lithium ESS Shipment as Class 9 Dangerous Goods

A lithium-ion energy storage system is not treated like an ordinary industrial machine at customs. Under the IMDG Code, lithium-ion cells and batteries are Class 9 dangerous goods, shipped under Packing Group II, according to DG Inspector's shipping compliance guide. Standalone cells or batteries are assigned UN3480; batteries packed with or inside equipment are assigned UN3481. Either way, a fully regulated shipment needs a bilingual Shipper's Declaration for Dangerous Goods listing the UN number, proper shipping name, packing group, package counts, and a 24-hour emergency contact.

Some importers assume a small or exemption-sized order will avoid this paperwork. It will not, for an ESS — IMDG Special Provision 188 only relieves very small cells and batteries, and an industrial ESS module is well above every threshold in it. The UAE Government's own services portal adds a second layer: restricted or hazardous goods categories require prior approval from the competent authority before import, with importers directed to the Federal Customs Authority and emirate-level customs commodity guides. Together, these two layers — international transport law and UAE import control — are why an uncertified or under-documented lithium ESS container can sit at Jebel Ali instead of moving to your warehouse.

The Pre-PO Document Checklist: What to Verify Before You Sign

The checklist below groups into three practical categories: transport-safety proof, the correct shipping mark, and (if relevant) a free-zone storage permit. None of these six items is optional for an industrial ESS shipment, and none can be produced quickly once a container is already booked — test reports and permits take time, so the right point to ask is before the PO, not after the deposit is paid.

Suppliers most often deliver the first two items in an incomplete form: a safety data sheet that only references UN38.3 instead of the actual test summary, or an IEC 62619 report written for a single cell instead of the assembled unit you are buying. The other four items are largely paperwork-matching problems, but they still cause holds when the details on one document do not match another.

Pre-PO Document Checklist for a UAE-Bound Lithium ESS Shipment

• ✓ Signed UN38.3 test summaryMust name the exact battery model on your PO, not a generic family name (Intertek)
• ✓ IEC 62619 test report at the assembled-rack or cabinet levelA cell-level-only report does not demonstrate system-level compliance (IEC; Envi Chambers)
• ✓ Shipper's Declaration for Dangerous GoodsBilingual, listing UN number, class, packing group, package count/type, and a 24-hour emergency contact (DG Inspector)
• ✓ Correct UN number on the shipping mark: UN3480 or UN3481Depends on whether cells ship standalone or packed inside the ESS cabinet (DG Inspector)
• ✓ TRAKHEES/PCFC dangerous goods storage permitNeeded only if the shipment stages or is warehoused within Jebel Ali Port or JAFZA (SmartQHSE; Boxman Global)
• ✓ HS 8507.60 classification confirmed on the commercial invoiceThe Harmonized System heading used for lithium-ion battery customs entries (Datamyne)

UN38.3 and IEC 62619: What Each Certificate Actually Proves

UN38.3 refers to Part III, subsection 38.3 of the UN Manual of Tests and Criteria. It requires lithium cells and batteries to pass eight sequential tests — altitude simulation, thermal cycling, vibration, shock, external short circuit, impact, overcharge, and forced discharge — before transport by air, sea, road, or rail, according to Intertek. A signed test summary must be available from the shipper on request throughout the supply chain. One summary is tied to a specific battery design and covers every shipment of that design — it does not need to be regenerated per container, but it must name the model you are actually buying.

IEC 62619 answers a different question. Now in its second edition, published 24 May 2022, it sets safety requirements for secondary lithium cells and batteries in industrial applications, and it explicitly lists energy storage systems among the stationary applications it covers, according to the International Electrotechnical Commission. Testing includes an external short-circuit test at 30 milliohms held for six hours, a thermal abuse test ramped to 85 degrees Celsius for three hours, an overcharge test past the rated voltage, and a forced discharge test — all judged on one criterion: no fire, no explosion, according to Envi Chambers' technical reference.

The detail buyers most often miss is scope. A certificate labeled IEC 62619 does not by itself prove the exact SKU you are quoted was the unit tested — a cell can pass, and the assembled rack built from that cell can still fail. Ask for the report number, testing lab, and test date, and confirm in writing that the report covers the assembled rack or cabinet, not only the cell inside it.

UN3480 or UN3481: Which Shipping Mark Applies to Your Container

The two Class 9 entries for lithium-ion batteries look similar but describe different physical situations. UN3480 covers standalone cells or batteries, not packed with other equipment. UN3481 covers batteries packed with, or already installed inside, the equipment they power, according to DG Inspector. Both sit in Class 9, Packing Group II.

For a containerized ESS cabinet, the batteries are almost always pre-installed inside the enclosure before it ships, which points to UN3481 rather than UN3480. This is not a minor labeling detail: the UN number on your Shipper's Declaration has to match how the cargo is actually packed, and a mismatch is exactly the kind of discrepancy a customs inspection is designed to catch.

UN3480 vs. UN3481: Which Applies to Your ESS Cabinet

	UN3480	UN3481
What it covers	Standalone lithium-ion cells or batteries, not packed with equipment	Lithium-ion batteries packed with or contained in equipment
Class and Packing Group	Class 9, Packing Group II	Class 9, Packing Group II
Typical containerized ESS cabinet	Rare -- most ESS units ship with cells already installed	Usual mark when batteries are pre-installed inside the cabinet or rack

Does the Small-Battery Exemption Apply to Your Order?

IMDG Special Provision 188 exists to spare very small consumer batteries from full Class 9 treatment. The relief only applies to lithium-metal cells at or below 1 gram of lithium, lithium-metal batteries at or below 2 grams aggregate lithium, lithium-ion cells at or below 20 watt-hours, and lithium-ion batteries at or below 100 watt-hours, according to a widely cited IMDG Code technical reference. An industrial ESS battery, assembled into a module or rack, sits far above every one of those numbers.

This matters because the exemption is based on the energy rating of the individual cell or battery, not order size. A one-unit pilot purchase of a full-size ESS module gets exactly the same Class 9 treatment as a container of forty units. If a supplier says a small trial order can skip UN38.3 or the Shipper's Declaration, ask them to name the specific threshold their product falls under — for an industrial ESS, there usually is not one.

The Small-Battery Exemption Does Not Cover ESS Modules

The Small-Battery Exemption Does Not Cover ESS Modules

IMDG Special Provision 188 only relieves lithium-metal cells at or below 1 g of lithium, lithium-metal batteries at or below 2 g aggregate lithium, lithium-ion cells at or below 20 Wh, and lithium-ion batteries at or below 100 Wh from full Class 9 marking, labeling, and documentation. An industrial ESS battery assembled into a module or rack is far above every one of these thresholds. Ordering a smaller pilot batch does not change this -- SP188 is based on the energy rating of the individual cell or battery, not the size of the order (Shashi Kallada).

Who Issues the Jebel Ali Storage Permit? TRAKHEES, Not Dubai Municipality

If your ESS shipment will be staged or warehoused inside Jebel Ali Port or JAFZA before final delivery, a separate question comes up: which authority issues the dangerous goods storage approval. HSE matters at Jebel Ali Port and JAFZA are regulated by TRAKHEES, the HSE arm of the Ports, Customs & Free Zone Corporation (PCFC) — not Dubai Municipality, according to a Trakhees/PCFC compliance reference. Organizations handling dangerous goods at JAFZA need an environmental permit and must file a chemical storage declaration with PCFC, a requirement corroborated by a separate freight and logistics guide. This only applies if your cargo actually sits in a Jebel Ali or JAFZA facility — if the container moves straight through to your own warehouse, the TRAKHEES permit is not the relevant document, but the Shipper's Declaration, UN38.3 summary, and standard Federal Customs Authority import approval still apply, per the UAE Government's own services portal.

One more document is worth flagging honestly rather than guessing at: MoIAT issues UAE Certificates of Conformity under the Emirates Conformity Assessment Scheme (ECAS) for regulated product categories, and applicants must submit an accredited-lab test report, according to MoIAT's own service page. Whether batteries or ESS units specifically sit on MoIAT's regulated-category list could not be confirmed from an official source in this research pass — treat it as a question for MoIAT or your supplier, not a confirmed requirement either way.

Does Your Shipment Need a TRAKHEES Storage Permit?

Will your ESS containers be staged or warehoused inside Jebel Ali Port or the Jebel Ali Free Zone (JAFZA) before final delivery?

• Yes -- staging or storage within Jebel Ali Port or JAFZA→ TRAKHEES, the HSE regulatory arm of the Ports, Customs & Free Zone Corporation (PCFC), requires an environmental permit and a chemical storage declaration before dangerous goods can be held on site -- not Dubai Municipality (SmartQHSE; Boxman Global).
• No -- the container moves directly to the final consignee without JAFZA storage→ The TRAKHEES storage permit does not apply, but the Shipper's Declaration for Dangerous Goods, the UN38.3 summary, and Federal Customs Authority import approval still travel with the container (u.ae).

Questions to Put to Your Supplier Before You Sign the PO

The checklist above translates into six direct questions worth asking before the PO, not after: the exact battery model on the UN38.3 summary, whether the IEC 62619 report covers the assembled rack or only the cell, which UN number (3480 or 3481) the Shipper's Declaration will carry, whether that model number matches your commercial invoice and packing list, who arranges the TRAKHEES permit if you stage at Jebel Ali or JAFZA, and whether a current MoIAT/ECAS certificate exists for the SKU. A supplier who answers all six with documents, not assurances, is the one whose container is least likely to sit at Jebel Ali waiting on paperwork.

Questions to Ask Your Supplier Before the PO

• ✓ Can you provide a signed UN38.3 test summary listing the exact battery model on our PO?A safety data sheet that only mentions UN38.3 is not the same as the test summary document
• ✓ Does your IEC 62619 report cover the assembled rack or cabinet, or only the individual cell?Ask for the report number, testing lab, and test date, not just a certificate logo
• ✓ Will this shipment ship as UN3480 or UN3481, and does the Shipper's Declaration reflect that?Confirm the mark matches how the batteries are actually packed
• ✓ Does the battery model number on the UN38.3 report match the model number on the commercial invoice and packing list?A mismatch is a documented reason for a hold at Jebel Ali
• ✓ If our shipment stages at Jebel Ali or JAFZA, is the TRAKHEES storage permit already arranged?Confirm who -- you or the supplier -- is responsible for filing it
• ✓ Do you hold a current MoIAT/ECAS Certificate of Conformity for this SKU, or should we confirm applicability ourselves?MoIAT's regulated-category list for this product line was not independently confirmed in this research pass -- verify directly

Frequently Asked Questions

Does a UN38.3 test summary need to be renewed for every shipment, or does one summary cover all shipments of the same battery design?

One signed UN38.3 test summary is tied to a specific battery design and covers every shipment of that design — it does not need to be regenerated for each container, according to Intertek's testing guidance. What must match every time is the model named on the summary against the model on your commercial invoice and packing list.

Will Jebel Ali customs release a container if the supplier only provides a cell-level IEC 62619 report instead of one covering the assembled rack or cabinet?

A cell-level report alone does not demonstrate the assembled rack or cabinet meets IEC 62619, since the standard's short-circuit, thermal abuse, overcharge, and forced-discharge tests are evaluated at the level tested, not extended upward automatically. Ask for a report explicitly scoped to the assembled unit, plus the report number, lab, and test date.

Can a small pilot order of ESS units qualify for the IMDG Special Provision 188 exemption to skip full Class 9 paperwork?

No. SP188 relief is based on the energy rating of the individual cell or battery — 20 watt-hours for cells, 100 watt-hours for batteries — not on order size. An industrial ESS module sits far above those thresholds whether you order one unit or forty.

Which UAE authority actually issues the dangerous goods storage permit for a Jebel Ali Free Zone warehouse?

TRAKHEES, the HSE arm of the Ports, Customs & Free Zone Corporation (PCFC), issues environmental permits and requires a chemical storage declaration for dangerous goods held at Jebel Ali Port or JAFZA — not Dubai Municipality. This only applies if your shipment is actually staged or warehoused within Jebel Ali or JAFZA.

What happens at customs if the UN38.3 test report lists a different battery model number than the one on the commercial invoice and packing list?

A mismatched model number is a documented, common reason for a customs hold, since the inspecting authority cannot confirm the tested design is the one inside the container. Confirm the model numbers match exactly before the shipment leaves the supplier's facility, not after it arrives at Jebel Ali.
