2-Propanol (isopropyl alcohol, CAS 67-63-0, UN 1219) is supplied as a clear, water-miscible flammable solvent with bulk assay typically 99.5 wt% or higher for export. The material is not a dual-use precursor and is not listed in Annex I of Regulation (EU) 2021/821, but its transport and hazard classification generate a multi-layer documentation chain. At 20 °C the liquid density is 0.785 g/cm³, vapour pressure is 4.4 kPa, and closed-cup flash point is 12 °C. The boiling point at 101.3 kPa is 82.5 °C. These values place 2-propanol in the lower flammable liquid band and make the bill of lading dangerous goods data a binding extension of the export licence, not a separate administrative note.

Isopropyl Alcohol Exporter Compliance Pack: One Checklist from Licence to Bill of Lading

The compliance pack should be structured as a single record from licence to bill of lading. The licence is the national export authorization; the bill of lading is the transport evidence. Between them sit four control planes: product registration, hazard communication, quality release, and dangerous goods transport documentation. Operators treating these as separate files are more likely to create mismatches in product name, consignee address, or package count.

Export licence verification starts with the national exporter registration. In the European Union, the shipment flows under the Union Customs Code and the exporter must hold an EORI number; no specific EU chemical export permit is required for 2-propanol. In China, the material may require export declaration under the Measures for the Administration of Import and Export of Chemicals and an electronic export licence if the destination jurisdiction requires it. The licence must state HS subheading 2905.12, which covers both propan-1-ol and propan-2-ol, and the identical consignee address that will appear on the bill of lading. If the product is re-exported or in-transit, the transshipment jurisdiction should be checked for its own chemical inventory and licensing rules.

Registration evidence is required where the importing jurisdiction or exporter maintains an inventory. Isopropanol is listed in the EU REACH substance inventory with EC number 200-661-7, the United States TSCA inventory, the Chinese IECSC, the Japanese CSCL, and the Korean REACH inventory. A bulk exporter should retain the ECHA registration number for the 2-propanol tonnage band, because the safety data sheet must carry this number in Section 1.1. Under REACH, the registration obligation is triggered at 1 tonne per year per registrant; under United States TSCA Chemical Data Reporting, reporting may be required at 25,000 lb per site per annum, but the duty is not a transport condition.

Hazard communication is governed by CLP Regulation (EC) No 1272/2008 and REACH Annex II. The CLP classification is Flam. Liq. 2, H225; Eye Irrit. 2, H319; STOT SE 3, H336. The label must carry the signal word Danger, the UN number 1219, and the flame and exclamation mark pictograms. Sections 1.1, 3, 9, and 14 of the SDS are the most frequently audited at port state control. Section 14 must list Class 3, packing group II, proper shipping name ISOPROPANOL, and the closed-cup flash point of 12 °C; if the SDS Section 14 says “isopropyl alcohol” while the bill of lading says “2-propanol,” the carrier may still accept the shipment if the UN number is identical, but documentary credit banks routinely reject such mismatches.

What Evidence Demonstrates Product Conformity Before Loading?

2-Propanol is produced by either direct hydration of propylene or hydrogenation of acetone. Direct hydration material tends to retain trace ethanol, diisopropyl ether, and propylene oligomers; acetone hydrogenation can leave residual acetone and branched hydrocarbon impurities. Gas chromatography with a polar polyethylene glycol capillary column and flame ionization detection gives sufficient resolution for diisopropyl ether and ethanol; the method must be validated for the specific impurity profile of the production route. A purity specification of 99.9 wt% is therefore not a single number; it is a declaration that the GC method can separate and quantify the process-specific impurities.

2-Propanol is hygroscopic; the water content rises in open systems, and the 2-propanol-water azeotrope at approximately 87.7 wt% alcohol and 80.4 °C means moisture removal is energy-intensive. Bulk storage should use desiccant breathers or nitrogen blanketing, and loading lines should be purged with dry nitrogen when ambient relative humidity exceeds 60%. Published data for specific water uptake rates in a given loading bay are limited; site validation is required before setting operational hold times.

Acidity is normally expressed as acetic acid equivalent and limited to ≤0.002 wt% for export grade. Acidic impurities can arise from oxidation and will attack unlined carbon steel. Non-volatile residue is an effective indirect check for rust, pipeline polymer films, and container carryover. Color measured by the platinum-cobalt scale should be ≤10 APHA; a higher value in package shipments frequently indicates drum liner breakdown or product contamination at the filling manifold.

Packaged lots are sampled under ISO 2859-1 general inspection level II with an acceptable quality limit appropriate to the consignee contract. For bulk shipments, sampling should be from a flowing loop after a minimum of 15 min of circulation, not from a static top sample, because lighter impurities can stratify. Each sample is split, sealed, and retained for at least the contractual period; the retained sample should be linked to the B/L by container number and loading date.

When the Cargo Moves as UN 1219 under IMDG, ADR, and IATA

Because the flash point is 12 °C closed cup, 2-propanol is a Class 3 flammable liquid with packing group II under all modal codes. The automatic ignition temperature is approximately 425 °C, and the lower and upper flammable limits are approximately 2.0 vol% and 12.7 vol%. Vapours are heavier than air and can travel to an ignition source; loading racks therefore require vapour return lines, earthing, and pump shut-off interlocks set below class limits of the local electrical classification.

The dangerous goods transport document must state the UN number 1219, proper shipping name ISOPROPANOL, class 3, packing group II, number and type of packages, gross and net mass, and the emergency response telephone number. Under IMDG Code Part 5.4 the document may be combined with the customs document, provided the dangerous goods description appears first. The IMDG Code assigns EmS F-E, S-D and does not classify 2-propanol as a marine pollutant. In ADR the hazard identification number is 33 and the tunnel restriction code is D/E. These codes should be copied into the carrier’s transport management system and checked against the original DG declaration, not retyped from memory.

UN-approved packaging for export drums is typically steel drum UN 1A1, marked with a Y rating for packing group II and a hydraulic test pressure declared on the package marking. Composite IBCs are marked 31HA1. Packaged shipments of Class 3 PG II may be limited quantity qualified in some modes at 1 L per inner packaging and 30 kg gross per outer package, but the suitability for maritime, road, and air must be verified against the current mode-specific table because packaging method and labels differ. For air transport, the applicable packing instruction and quantity limitation under the current IATA Dangerous Goods Regulations must be confirmed; the road and maritime limited quantity values do not transfer because air transport may impose more restrictive limits and a different inner packaging arrangement.

Bulk parcels are typically shipped in stainless steel ISO tank containers or in IMO Type 2 chemical tankers. The tank type is not automatic; the consignor must verify that the tank code in the ADR/RID tank record, such as LGBF, is valid for UN 1219 in the current ADR edition. The tank cleanup before loading should be verified by wall wash or final rinse analysis for non-volatile residue and odor; the cleanliness certificate should be cross-referenced to the product CoA and the bill of lading tank number.

Documentary Reconciliation at the Bill of Lading Interface

The bill of lading for a packaged or bulk 2-propanol shipment must not be a casual paraphrase of the commercial invoice. It must carry the shipper, consignee, notify party, port of loading, port of discharge, vessel name and voyage, container number, seal number, number and kind of packages, gross mass, net mass, UN 1219, ISOPROPANOL, Class 3, PG II, flash point 12 °C c.c., and the emergency response telephone number. If the shipment is under letter of credit, the B/L must be signed in a form acceptable under UCP 600 articles 20–24; the consignee and notify party must match the commercial invoice and packing list exactly.

Containerized shipments require a verified gross mass under SOLAS regulation VI/2. The VGM declaration includes the shipper name, container number, VGM, and method of weighing. Maritime security filings add the exporter, seller, buyer, manufacturer, ship-to party, and country of origin. In the European Union, the entry summary declaration is filed through the Import Control System; in the United States, the Importer Security Filing must include the HS number 2905.12 and the foreign port of lading. These data should be re-checked against the B/L cut-off before the ocean carrier closes the manifest.

Post-loading corrections to the bill of lading are a recognized source of demurrage and container detention. The export compliance pack should therefore include a final checklist that compares the export licence consignee, the dangerous goods declaration proper shipping name, the certificate of analysis batch number, the packing list package count, the VGM certificate container number, and the bill of lading. Any change to a single data field after export declaration submission should trigger a formal amendment, not an informal email instruction.
