Since 1 July, Your Lithium Battery Export Needs a Pack Design Code — Miss It and the Filing Gets Stuck
Since 1 July, Your Lithium Battery Export Needs a Pack Design Code — Miss It and the Filing Gets Stuck
Executive Summary
Your lithium battery shipment now hits a hard wall at China's export filing system. Since 1 July, a new mandatory field — the Pack Design Code — must sit in the single-window declaration, and the system checks it against your UN38.3 report line by line. Leave it blank and the filing fails before your cargo ever reaches the quay.
What Changed on 1 July
The China Electronic Port Data Center pushed a notice on June 30 and switched the rules on the morning of July 1, and the change hits the export filing system for two product groups: lithium-ion batteries (a Class 9 dangerous good, shipped as UN3480 or UN3481) and lead-acid batteries.
The quiet but real shift is the field once labelled "battery capacity." It is now "battery energy." Sounds like a rename. It isn't. It forces you to file exactly as your UN38.3 test report reads — nominal voltage, rated capacity, and Wh, all matching.
My read: this is not a wording tweak. It is a validation rule wired into the system. Keep typing "capacity" out of habit and the system rejects the match against UN38.3.
The painful part? Many small and mid-size traders let their customs broker fill the form. The broker did not update the fields either. Two sides, one mismatch, and the filing stalls.
}The One New Field That Bites
The sharpest cut is a new mandatory field: the Product Pack Design Code. Customs is now inspecting lithium battery packaging down to the design level. You must pull this code from your factory or packaging team before you file. No blanks allowed.
Plain truth: a lithium export used to clear with a DG certificate, an MSDS, and a UN38.3 report. Now there is one more gate — the packaging design code itself goes into the system. Wrong code means non-compliant packaging.
One linked change helps you: a new "pre-screening import plus change or cancel" function. Good news — you can edit or pull a submission after you send it. But the catch is, every edit leaves a trace. Faking it just got harder.
}Key Data
| Item | Before 1 July | From 1 July |
|---|---|---|
| Pack Design Code in filing | Not required | Mandatory field |
| Pre-screening import / change / cancel | Not available | Available, fully logged |
| System validation vs UN38.3 | None | Hard, line-by-line |
| Lithium & lead-acid inspection | Routine spot check | Nationwide campaign, ratio up |
The numbers that matter to your quote: effective date July 1 2026; two battery types covered (lithium, HS 8507; lead-acid); penalty exposure from ¥30,000 to ¥50,000 per shipment and rising; one character off in the UN38.3 field and your filing can sit for 2 days.
Customs Is Checking for Real This Time
The General Administration of Customs has launched a nationwide special inspection on battery exports, covering both coastal and inland ports. Lithium and lead-acid batteries are named specifically, and on-site inspection ratios are up across the board. The targets are clear: non-compliant DG packaging, wrong or missing labels, and false declarations.
Four Things to Check on Your Next Shipment
① The UN38.3 report name and parameters must match the filing fields character for character. Use "energy," not "capacity."
② Get the Pack Design Code from your factory and put it in the system. Don't leave it empty.
③ The DG certificate (performance cert plus use appraisal), the DG class, and the UN38.3 report must all be present, and the packaging category must match the goods.
④ SDS section 14 cites the latest version, and labels are applied correctly. Fudge any one of these four and the special inspection will catch it.
Frankly, this round of lithium battery filing is for real. Stop expecting your broker to cover for you. One wrong field and a returned filing is the small problem — getting flagged for high-ratio inspection and a credit downgrade is what hurts. One shipment can run ¥30,000 to ¥50,000 in penalties, and serious cases bring double penalties plus criminal exposure that can sink a small trader's export licence for good.
Here is a real one from last month: a lithium battery shipment showed "3200mAh capacity" in its UN38.3 report, but the system wanted "3200mAh energy." One character off, and the filing sat for two days before release. The sailing window slipped for nothing.
Bottom line: spend 30 minutes today checking these four items. That beats scrambling at booking and rewriting the filing until the vessel sails. Don't wait. Get the Pack Design Code in hand today.
Market Outlook
Rates and capacity are the headline most weeks. This week the story is paperwork. Customs is shifting battery DG control from "spot-check the documents" to "hard system validation plus targeted inspection," and the net is tightening. Expect inspection to get finer from here, not looser. The same hard-validation approach is spreading to other hazardous and chemical exports — so don't assume your product is safe just because the new code is not on your desk yet.
JETWAY Supply Chain runs a dedicated dangerous-goods desk for lithium and other battery cargo out of Tianjin and the major Chinese ports, licensed as an NVOCC (MOT) and a member of CIFA, FIATA and WCA. We review your UN38.3, DG certificate, and SDS before you stuff the box — so the Pack Design Code and every field line up the first time, not after a two-day stall.
