Sources and versions
Rule queries use structured IMDG 42-24 entries and associated special provisions, packing, tank and segregation rules. Chinese source material was supplied by the site owner. Some Chinese display names were corrected following the owner’s checks against a printed book; those corrections are distinguished below from public official sources.
42-24 became mandatory on 1 January 2026. Amendment 43-26 has been adopted, with voluntary application from 1 January 2027 and envisaged entry into force on 1 January 2028. The site has not completed a full 43-26 data upgrade. See the official sources for status and application arrangements.

What the review covers
- Editorial explanations: 27 articles and 24 FAQs reviewed, focusing on classification boundaries, subsidiary risks, quantities, packaging, labels and version dates. Each article now lists sources, clause pointers and a review date. Editorial work uses automated tools; it is not certification of a shipment by a qualified dangerous-goods specialist.
- Rule-data checks: automated checks cover field structure, entry relationships and regression examples. They do not prove that every UN field has been independently checked against an authorized book.
- Conditional fields: “See SP”, “See 2.0.6.6” and footnotes require further decisions. An unresolved condition is shown as pending, not converted to “none”. The actual goods, classification evidence and transport arrangements remain necessary.
Open punctuation review
28 source-punctuation candidates were screened. Three English semicolons are enumeration separators; one English comma is consistent with the supplied source and historical UN text. The remaining 24 Chinese candidates still need comparison with the same edition of an authorized printed book. Candidates are not confirmed defects; no bulk deletion was applied.
Entry-condition review · 2026-10-24
Automated structural checks covered 2,348 UN numbers, 2,862 entries and 5,724 language-name values. Percentage, micron-unit and adjacent-duplicate screening covered 2,860 bilingual entries. The seven UN numbers below received source-based corrections to nine Chinese names; this is not a claim that every regulatory field has been manually verified.
- UN1010 — Butadiene threshold in the mixture corrected from 40% to 20%.
- UN1345 — The second alternative uses 840 micrometres, not nanometres.
- UN1748 — Available oxygen in the first entry corrected from 8.9% to 8.8%.
- UN1835 — PG II is more than 2.5% but less than 25%; PG III is not more than 2.5%, with explicit boundary conditions.
- UN1942 — Removed the repeated exclusion of added substances; the 0.2% limit remains.
- UN2208 — Restored the range: more than 10%, but not more than 39%, available chlorine.
- UN2870 — The substance and in-devices entries have their matching Chinese/English names; the latter has no listed packing group.
Corrections preserve the original source text and record the amendment, source page, old value, corrected value and applicable entry. A changed source or entry identity must be reviewed before that correction can be reapplied.
Confirmed correction history
Chinese entry conditions corrected for seven UN numbers
Checked seven UN numbers against the official IMO table and MSA amendment. Nine Chinese names were corrected: UN1010 concentration, UN1345 particle-size unit, UN1748 available oxygen, UN1835 low-concentration condition, UN2208 missing chlorine range, UN1942 repeated clause and the two UN2870 names. Source records are retained.
View related page →Blank packing groups and consistent label entries
UN2028 and the UN2870 in-devices entry no longer inherit deleted packing groups. Labels now use the same English entry for classification and quantity conditions, correcting the UN1891 flammable-liquid and toxic subsidiary labels. LQ/EQ references to special provisions remain conditional.
View related page →Knowledge-base and FAQ review
Reviewed 27 articles and 24 FAQs; revised 25 older articles and all FAQs. Corrections cover GHS versus transport subsidiary risks, LQ conditions, packaging mark S, UN2031 concentration entries and UN1361 requirements. Added source and clause pointers.

43-26 was adopted by MSC.587(111), with voluntary application from 1 January 2027 and envisaged entry into force on 1 January 2028. Site queries still use 42-24; a full 43-26 data review has not been completed.
View related page →Chinese battery and vehicle names corrected
UN3480 and UN3481 Chinese display names were corrected following the owner’s check against a printed book. UN3556–3558 use the Chinese wording for “powered”. This records an owner-supplied correction, not independent publisher certification.
View related page →Conditional subsidiary risks remain unresolved until classified
Entries such as UN3541 link to 2.0.6.6 and require classification of their contents. A clause reference is not “no subsidiary risk”; segregation results retain the pending-classification notice.
View related page →UN3166 name and conditional EmS explanation
The Chinese vehicle name follows the owner’s printed-book check. EmS is shown conditionally: F-D, S-U for gaseous fuel and F-E, S-E for liquid fuel, rather than treating the footnote as missing data.
