SOLAS Chapter VI, Regulation 2 sets out one of the most frequently misunderstood documentation duties in maritime cargo operations: the shipper’s obligation to furnish the master with adequate cargo information before loading. What often gets missed is that this single regulation actually splits into two separate documentation tracks depending on how the cargo is carried — packaged general cargo follows sub-chapter 1.9 of the CSS Code, while solid bulk cargo follows Section 4 of the IMSBC Code. Layered on top of this is the container Verified Gross Mass requirement, and, for cargoes carrying a competent-authority exemption from dangerous goods provisions, the question of exactly where that exemption certificate needs to be attached. This flowchart walks through the full decision path: packaged vs. bulk, which VI/2 sub-paragraph and reference document applies, whether VGM is triggered, and whether an IMDG 5.4.4.2 or IMSBC 1.5 exemption certificate needs to travel with the cargo information.

Packaged vs. bulk  →  VI/2 sub-paragraph  →  form  →  VGM  →  where an exemption certificate attaches (IMDG 5.4.4.2 for packaged · IMSBC 1.5 for bulk)

Decision / structure Source document / certificate Yes → action required No → default path
CARGO TO BE LOADED — SOLAS VI/2 APPLIES
Is the cargo carried packaged, or in bulk?
PACKAGED / GENERAL CARGO
VI/2.2.1 CSS Code sub-chapter 1.9 General description · gross mass · special properties
What this covers
  • General description of the cargo
  • Gross mass of cargo / cargo units
  • Relevant special properties
Is the cargo packed in a freight container?

Excludes ro-ro chassis/trailer movements on short international voyages

YES
📄 DOCUMENT VGM required — VI/2 paras 4–6 Verified, signed, sent to master/terminal rep before stowage planning
Full requirement
  • Method 1 (weigh packed container) or Method 2 (piece weights + tare)
  • Submitted in time for the stowage plan
  • No VGM → cargo is not loaded
NO
VGM not required VI/2.3 gross-mass-matches-declared duty still applies
Is the cargo exempted from the IMDG Code by a special provision?

e.g. SP 922 · 928 · 931 · 935 · 939 · 954 · 964 · 979 — tap for details

SP 922
Lead phosphite, dibasic — UN 2989.
SP 928
Fish meal, UN 1374 / UN 2216 — exempt with a certificate of no self-heating properties.
SP 931
Metal borings, UN 2793.
SP 935
Zinc ashes — UN 1435.
SP 939
Phthalic anhydride — UN 2214.
SP 954
Hay, straw or bhusa, UN 1327.
SP 964
Potassium nitrate (UN 1486), sodium nitrate (UN 1498), sodium/potassium nitrate mixture (UN 1499).
SP 979
Carbon / charcoal entries — replaced former SP 925 in Amdt 42-24.
YES
📄 CERTIFICATE Exemption certificate replaces the DGD No DGD is generated — certificate rides with the CSS 1.9 cargo information required by SOLAS VI/2
Why
  • The exemption removes the cargo from IMDG scope entirely
  • IMDG 5.4.4.2 keeps the certificate in the paper trail regardless
NO
Standard documentation DG Transport Document (if classed DG), or ordinary shipping documents (if not)
SOLID BULK CARGO
VI/2.2.2 IMSBC Code Section 4 BCSN · group · class/UN No. · stowage factor · trimming · moisture/TML
Full 18-item list (4.2.2)
  • BCSN, group A/B/C, IMO class & UN No. if applicable
  • Quantity, stowage factor, bulk density, trimming
  • Angle of repose, wet-base likelihood, gas hazards
  • Moisture/TML certificate (Group A), MARPOL Annex V status
  • Signed on Form for Cargo Information (4.2.3)
VGM — not applicable Bulk cargo loaded directly into cargo spaces; VI/2 paras 4–6 apply to containers only
Has a competent authority granted an exemption from an IMSBC Code provision?

IMSBC 1.5 “Exemptions and equivalent measures” — a separate mechanism from IMDG 5.4.4.2

YES
📄 CERTIFICATE Attach exemption certificate Certificate rides with the IMSBC Section 4 cargo information required by SOLAS VI/2
Why
  • IMSBC 1.5 lets a competent authority exempt a cargo from an IMSBC provision
  • Check the “Exemption certificate” box on Form 4.2.3
NO
Standard certification TML/moisture, weathering, or other certificates per the individual schedule
All cargo information & certificates confirmed in writing, submitted to master / terminal representative sufficiently in advance of loading
