Solvent Safety & MSDS: Packing CIJ Consumables for DDP
Solvent Safety & MSDS isn’t a paperwork ritual—it is the operating system for every Delivered Duty Paid (DDP) shipment of CIJ inks and make-up. Treat the SDS (especially Section 14) as the single source of truth that drives classification, packaging, marks/labels, documentation, and ultimately whether the box is accepted by air, sea, and road along a multi-modal route. This page translates regulation-speak into a practical, auditable sequence you can ship with—without surprises at the airline acceptance counter or customs.
Context for CIJ: fast-drying performance depends on volatile solvents (MEK, acetone, ethanol, isopropanol) and low-viscosity carriers; that same volatility makes many products Class 3 Flammable Liquids under transport rules. When you sell DDP, you wear every hat—classifier, packager, declarant, importer of record—and absorb every cost of non-compliance. The way out is a repeatable cascade: Hazard profile → SDS → Mode rules (IATA/IMDG/ADR) → UN packaging/marks → Documents → IOR/clearance, all locked to the most stringent leg (usually air).

A quick map for busy shippers (overview + pitfalls)
- Decide the hazard once: lock UN number, Proper Shipping Name (PSN), Class, Packing Group (PG) from a complete, GHS-compliant SDS (16 sections).
- Build to the strictest mode: if any leg is by air, design to IATA robustness and “Y” Limited Quantity (LQ) where eligible.
- Choose the right box: UN specification packaging when required; know when LQ removes the UN-spec box requirement (but not robustness).
- Mark/label correctly: LQ, hazard labels, UN ID/PSN, orientation arrows, overpack, marine pollutant if relevant. Check visibility after stretch-wrap.
- Document perfectly: DGD (air), DG manifest (sea), papers/CMR (road), commercial invoice alignment, and importer-of-record (IOR) readiness for DDP.
- SDS Section 14 conflicts with declared UN/PG on DGD or invoice.
- LQ “Y” mark missing for air, or wrong dimensions/contrast on labels.
- Overpack hides hazard labels/UN ID; no extra marks on overpack.
- Closure instructions not followed (tape pattern/torque/liner omitted).
- Gross mass per package exceeds rating on UN mark or LQ cap.
1) SDS as your single source of truth (16 sections, Section 14 is decisive)
Your SDS must be GHS-aligned with a consistent 16-section layout. For transport, Section 14 shall list the UN number, PSN, class, packing group, environmental hazards (e.g., marine pollutant), and the modal-specific notes (air/sea/road). Never rely on a “ground-only” classification when the shipment will fly; multi-modal DDP obligates the strictest interpretation. If a supplier cannot provide a complete SDS, treat it as a blocking risk.
| Section | Title (GHS) | Shipping relevance |
|---|---|---|
| 1 | Identification | Emergency contact; product identifiers must match invoice/labels. |
| 2 | Hazards Identification | GHS pictograms; helps align internal training with Class 3 handling. |
| 3 | Composition/Information | Mixture components for blending FP estimation & marine pollutant status. |
| 7–8 | Handling & Exposure Controls | PPE for pack-out; aligns with airline acceptance expectations. |
| 9 | Physical & Chemical Properties | Flash point (FP) and initial boiling point (IBP) underpin PG decision. |
| 10 | Stability & Reactivity | Thermal limits; informs storage temperature in transit. |
| 14 | Transport Information | UN/PSN, Class, PG, LQ flags, marine pollutant—your legal baseline. |
| 16 | Other Information | Revision date & version control (audits want this). |
- UN number & PSN present and unambiguous (no “not regulated” if any air leg is planned).
- Class 3 confirmed; Packing Group (I/II/III) aligns with flash point & initial boiling point.
- Modal notes present: IATA (air), IMDG (sea), ADR/49 CFR (road); marine pollutant if applicable.
- Emergency phone (24/7) & supplier info present; Section 7/8 coherent with Section 9/10.
- Latest revision date & language matches shipping documents.

2) Hazard profile of common CIJ solvents (why PG matters)
Most CIJ make-up and many inks are dominated by Class-3 flammables. PG drives how much you may place in each inner packaging, whether passenger aircraft are allowed, and what robustness/marks are required. Below is an indicative (training) table; always follow your mixture SDS.
| Solvent | FP (°C) | IBP (°C) | Usual PG* | Notes |
|---|---|---|---|---|
| Acetone | ~ −20 | ~ 56 | II | Very volatile; aggressive solvency; drying accelerator. |
| MEK (2-butanone) | ~ −6 | ~ 79–80 | II | Fast-drying workhorse; frequent CIJ make-up carrier. |
| Ethanol | ~ 13 | ~ 78 | II/III | Mixtures may push PG III depending on composition. |
| Isopropanol | ~ 12 | ~ 82 | II | Common cleaner/flush; similar airworthiness constraints. |
*Always follow the SDS for your actual mixture; PG is mixture- and test-dependent.
If a mixture is dominated by a low-flash solvent, expect the mixture’s FP to trend toward the lowest contributor. For teaching purposes only:
FP_mix ≈ min(FP_components) + Δ(composition, non-idealities)Always confirm FP using the tested value in SDS Section 9 (closed-cup).
For formulation context (MEK vs ethanol vs dye-/pigment families) that also impacts emissions and storage safety, see CIJ Ink Families: MEK vs Ethanol vs Dye-Pigment.

3) Packing Group decision anchor (flash point & IBP)
Packing Group is the single most consequential data point: it gates quantity limits (inner and per package), packaging performance level, and passenger vs cargo eligibility. A simplified teaching aid (not a substitute for modal tables):
PG ≈ f(FlashPoint, IBP)Very low FP and IBP → PG I; low FP with IBP > 35 °C → PG II; FP 23–60 °C → PG III. Always validate against the legal tables for your UN entry.
| Case | FP / IBP | Likely PG | Passenger aircraft? | Comment |
|---|---|---|---|---|
| A | −20 °C / 56 °C | II | Restricted by PI | Acetone-rich mixture; strict limits per PI. |
| B | 13 °C / 78 °C | II/III | Check PI | Ethanol-dominant; some recipes get PG III. |
| C | 40 °C / 100 °C | III | Often allowed | Higher FP blend; still Class 3. |

4) Mode-by-mode: why you build to air (even when most miles are by truck)
Air (IATA DGR): the strictest leg. LQ by air requires the “Y” LQ mark, hazard labels as applicable, a Shipper’s Declaration (DGD), and robustness equal to surviving a 1.2 m drop test (and stacking) for the completed package. Some PG I entries are prohibited on passenger aircraft. Package all the way to the most demanding PI your route may touch.
Sea (IMDG): LQ packages carry the LQ mark and appear on the DG manifest; hazard labels may be relieved for LQ, but marine pollutant status (if any) triggers the marine pollutant mark. Stowage/segregation rules apply in the container.
Road (ADR / 49 CFR): Often the most permissive for LQ (≤30 kg gross mass per package common), square-on-point LQ mark, and (in many jurisdictions) relief from full shipping papers/labels—yet remember, a multi-modal DDP route must withstand air acceptance if there is any flight segment.
| Item | Air (IATA) | Sea (IMDG) | Road (ADR/49 CFR) |
|---|---|---|---|
| LQ Mark | Square-on-point with Y | Square-on-point (no Y) | Square-on-point (no Y) |
| Shipper’s Declaration | Required | DG manifest | Papers vary; some reliefs |
| Package Robustness | 1.2 m drop + stack | Drop/stack per code | Per code |
| Passenger vs Cargo | PI dictates | N/A | N/A |

5) UN packaging vs. LQ robustness—what the box must tell the airline
Two questions decide the box: Do you need UN specification packaging? and What marks must be visible after palletizing? LQ can relieve the need for UN-spec packaging on certain modes, but you still owe the package performance (drop/stack) and all required marks/labels for that mode. When UN-spec packaging is required, a UN mark embossed/printed on a non-removable surface certifies the tested performance.
| Field | Meaning | You check |
|---|---|---|
| 4G | Packaging type & material (4G = fiberboard box) | Matches PI/packing instruction. |
| Y | PG II performance (X = PG I; Z = PG III) | ≥ your product PG. |
| 30 | Max gross mass permitted (kg) or hydrostatic pressure (kPa) | Your packed gross ≤ rating. |
| S | “Solids/inner packagings” (combination pack) | Liquids may show kPa ratings. |
| 25 | Year of manufacture (e.g., 2025) | Age limits if applicable. |
| USA | Country authorizing the mark | Matches compliance docs. |
| M4460 | Manufacturer/agency code | Closure instructions on file. |
| Code | Meaning | Typical use in CIJ fluids |
|---|---|---|
| 1A1 | Steel drum, non-removable head | Bulk inbound solvent bases, not LQ. |
| 3H1 | Plastic jerrican, non-removable head | 1–5 L inner packagings. |
| 4G | Fibreboard box | Combination packs with small bottles (typical for LQ). |

6) Marks & labels that survive the pallet stretch-wrap
Across modes, you’ll meet these icons most often: the square-on-point Limited Quantity mark (with a bold Y in the center for air), hazard class labels (Class 3 flame), UN ID number near the PSN, orientation arrows for inner glass/plastic, Marine Pollutant mark for sea, and “OVERPACK” when you re-consolidate. Verify size (often ≥100 mm for labels), contrast, and durability; ensure nothing is obscured by corner posts or pallet straps.
| Item | Typical size | Notes |
|---|---|---|
| Class 3 Label | ≥ 100 × 100 mm | Diamond; durable/contrast; not hidden by straps. |
| LQ Mark (air) | Square-on-point, sides ≥ 100 mm, with “Y” | “Y” strictly for air LQ only. |
| UN Number | ≥ 6 mm text | Near PSN; legible after wrap. |
| Orientation | Arrows ≥ 100 mm tall | When required for inner containers. |

7) Paperwork that actually clears (and what DDP adds)
Air (IATA) Shipper’s Declaration (DGD): exact PSN/ID, class, PG, quantity per PI, overpack statements, packing attestation, emergency contact. Sea (IMDG) DG manifest: include marine pollutant when applicable. Road: shipping papers or CMR notes per jurisdiction; LQ may enjoy certain reliefs. DDP overlay: commercial invoice & pack list must carry the same PSN/UN and hazard notes; the import declaration (HS codes, IOR/EORI) must match. Price your DDP to include inspections, storage/demurrage, DG add-ons, and the cost of failures (repack, relabel, return).
| Field | What must match | Typical error |
|---|---|---|
| UN/PSN | SDS Section 14 & labels | UN1993 written as UN 3295 (wrong entry) |
| Class/PG | SDS & PI | PG mismatch (II vs III) |
| Qty/Packaging | PI & LQ eligibility | Inner volume over limit |
| Overpack | Extra marks on overpack | Labels hidden by wrap |
| Emergency contact | 24/7 reachable | Voicemail/non-24/7 |

8) A one-page SOP pattern you can adapt (with costing)
- Classify & lock: SDS Section 14 sets UN/PSN/Class/PG; record in a Control Sheet (UN, PSN, Class, PG, PI, LQ flag, Rev. date).
- Select packaging: UN-spec vs LQ; choose inner sizes; enforce closure instructions; prepare labels in batch with print log.
- Mark/label: LQ (Y for air), Class 3, UN ID/PSN, orientation, marine pollutant if applicable; plan overpack visibility.
- Self-test: mock 1.2 m drop (air) and stack; record photos & brief memo in job folder.
- Document: DGD/manifest + shipping papers; mirror data on invoice & pack list; HS code + IOR/EORI ready for DDP.
- Pre-alert: send scans to forwarder/airline; confirm acceptance windows & DG surcharges; secure space.
- Clearance: DDP importer documents pre-validated; confirm DG handling at destination; factor storage time.
- Audit & learn: add acceptance findings to a living checklist; update print templates if a label was queried.

9) Three mini case studies (acceptance logic in action)
Case A — Air LQ success with ethanol-dominant make-up: SDS: UN 1170 ETHANOL SOLUTION, Class 3, PG II. Inner 250 mL × 4 per 4G box; LQ by air with “Y” mark; Class 3 label + UN 1170 near PSN; DGD completed; overpack with labels repeated. Passed acceptance; no remarks.
Case B — Sea LQ with no air leg, but marine pollutant absent: SDS: UN 1993 FLAMMABLE LIQUID, N.O.S. (contains MEK), Class 3, PG II; not marine pollutant. LQ by sea with standard LQ mark; DG manifest; container placarding as required for other cargo. Cleared without hazard labels on package (per LQ relief).
Case C — Road only (ADR), 1 L inners, 12 per box: SDS same as Case B. LQ road with square-on-point mark; ≤30 kg gross mass per package; papers relief in some jurisdictions. Customer later added an air leg—had to repack to air LQ standard and issue DGD. Lesson: build to potential air constraints early.
10) FAQ — twelve fast answers
Q1. Can I ship CIJ make-up “non-hazmat” if packed tiny?
No. If the SDS/UN entry says Class 3,
it remains DG. Limited Quantity reduces some burdens; it does not erase the hazard class.
Q2. Does LQ by air remove the Shipper’s Declaration?
No. Air LQ uses the Y-mark and still needs
a DGD plus hazard labels.
Q3. Is a UN-spec box always required for LQ?
Not across all modes. Air LQ focuses on robustness
(drop/stack) and marks; sea/road rules differ. Always check the specific entry.
Q4. What if my supplier’s SDS says “not regulated by ground”?
Multi-modal DDP must survive the
strictest leg—air. A “ground-only” note is irrelevant if you fly.
Q5. Do I need marine pollutant marks for acetone/ethanol?
Only if the SDS/IMDG table identifies
the mixture as marine pollutant. Many common CIJ solvent mixtures are not—but verify your exact formula.
Q6. Do orientation arrows apply to plastic inners?
They can, depending on inner packaging
design and code requirements. Follow your PI/Section 14 notes.
Q7. Passenger vs cargo—how do I know?
Your UN entry + PI decides. PG and quantity limits are
decisive. When in doubt, assume cargo-only and design robustly.
Q8. Can I print smaller labels to fit the box?
No. Minimum sizes are mandated; reduce label
count with careful layout, not size.
Q9. Can overpack “inherit” inner labels?
Overpack must show necessary marks/labels if the
originals are obscured. “OVERPACK” text may be required—check code.
Q10. What photos should I keep?
All faces of the packed box (pre-wrap), close-ups of
labels/marks, scale/ruler in frame, and palletized visibility.
Q11. How do I justify an airworthiness drop test?
Keep a simple internal test memo with date,
height (1.2 m), pass/fail notes, and photos; this satisfies many practical acceptance checks.
Q12. What if the flight changes last minute?
If a passenger aircraft replaces cargo-only,
ensure quantity/PI compliance was built to the stricter leg. This is why we “build to air” from the start.
