Yes. Importing flammable liquids such as solvents, adhesives, paints, and alcohols into Japan can trigger a separate permit requirement under the Fire Services Act (消防法) once the material is stored or handled domestically, independent of the IATA DGR or IMDG Code documentation that governs the international transport leg. The two layers answer different questions, and satisfying one does not satisfy the other.
Does the Fire Services Act Apply to Imported Flammable Liquids?
Yes, if the substance qualifies as a Hazardous Material (危険物) under the Fire Services Act (消防法). Solvents, adhesives, paints, alcohols, and similar products typically fall under Class 4 flammable liquids (引火性液体), the most common of the six Hazardous Materials Classification (危険物類別) categories: Class 1 oxidizing solids/liquids, Class 2 flammable solids, Class 3 self-igniting or water-reactive substances, Class 4 flammable liquids, Class 5 self-reactive substances, and Class 6 toxic or corrosive substances.
This classification governs how the material is stored and handled once it is inside Japan. It sits alongside, and is triggered independently of, the customs and import-declaration process covered in Importing Dangerous Goods to Japan - IATA, IMDG & Regulatory Compliance Guide 2026. A shipment can clear customs cleanly and still create an unaddressed Fire Services Act obligation once it reaches a warehouse.
What Is the Difference Between Fire Services Act Classes and IATA DGR/IMDG Dangerous Goods Classes?
They overlap in substance but are not the same system, and neither one substitutes for the other. IATA DGR and the IMDG Code classify a shipment for the movement itself, air or sea, and dictate packaging, marking, and shipper's declaration paperwork for that leg. The Fire Services Act (消防法) classifies the same material for domestic storage and handling once it has landed in Japan, using its own six-class Hazardous Materials Classification (危険物類別) system rather than the DGR/IMDG class numbers.
A drum of acetone can be DG Class 3 (flammable liquid) for the flight or voyage and simultaneously fall under Class 4 flammable liquids (引火性液体) for warehouse storage in Japan. Completing the DG Class 3 shipper's declaration correctly says nothing about whether the receiving warehouse has crossed a threshold that requires a storage permit or a licensed handler on site. Compressed gas imports face a comparable second-layer permit issue under a different statute, detailed in Do You Need a Separate Permit to Import High-Pressure Gas Into Japan in 2026?; the mechanism there, a distinct domestic safety regime layered on top of transport documentation, is structurally the same pattern that applies to flammable liquids under the Fire Services Act.
When Do You Need a Hazardous Materials Handler License or Storage Permit?
The trigger is crossing a designated quantity (指定数量) set per substance, not volume in the abstract. Designated quantities for Class 4 flammable liquids are set under the Cabinet Order Concerning Regulation of Hazardous Materials (危険物の規制に関する政令), with different thresholds depending on the specific petroleum class and on whether the liquid is water-soluble or non-water-soluble; a solvent and an alcohol in the same Class 4 category do not necessarily carry the same threshold. Once storage or handling volume at a given site crosses the applicable threshold for that substance, the Fire Services Act requires a licensed Hazardous Materials Handler (危険物取扱者) to be responsible for the site and, separately, a storage or handling permit for the facility itself.
Below the threshold, day-to-day handling can generally proceed without the license or the facility permit, but the threshold is substance-specific and category-specific rather than a single number that applies across all flammable liquids. Confirming which threshold applies to a given product, and whether a given warehouse's planned volume crosses it, is a classification exercise that has to be run against the actual substance data sheet, not assumed from the product category alone.
Who Handles the Fire Services Act Filing When Aplash Manages the Import?
Aplash assesses the DG classification for the shipment, identifies the applicable Hazardous Materials (危険物) class and designated quantity threshold, and advises on whether a storage permit is required for the intended facility. The Hazardous Materials Handler (危険物取扱者) license itself attaches to the individual present at the storage site, so that role and the facility-level permit filing with the Local Fire Department (消防署) having jurisdiction over the warehouse sit with the client's own staff or their appointed handler at that location. Customs clearance and the underlying trade compliance documentation are handled through our customs and trade compliance practice, scoped to the import transaction rather than to the ongoing operation of a domestic storage site.
That division keeps each piece of the compliance chain with the party that actually controls it: the transport-leg DG paperwork with the shipper of record, the classification and threshold assessment with Aplash, and the site-level license and permit with whoever operates the warehouse day to day.
Key points:
(a) The Fire Services Act (消防法) governs storage and handling of Hazardous Materials (危険物) inside Japan and applies independently of both customs import procedures and IATA DGR/IMDG transport documentation.
(b) Class 4 flammable liquids (引火性液体) covers most imported solvents, adhesives, paints, and alcohols, but the designated quantity (指定数量) that triggers a license and permit requirement is set per substance under the Cabinet Order Concerning Regulation of Hazardous Materials (危険物の規制に関する政令), not by a single volume figure for the whole category.
(c) Crossing the applicable threshold requires a licensed Hazardous Materials Handler (危険物取扱者) responsible for the site and a separate storage/handling permit filed with the Local Fire Department (消防署) covering that location, distinct from any DG transport paperwork already completed for the shipment.
Frequently Asked Questions
If our DG shipper's declaration is already approved, do we still need a Fire Services Act permit?
Possibly, and the DG declaration does not answer that question either way. The shipper's declaration covers the IATA DGR or IMDG transport leg; the Fire Services Act permit question depends on the Hazardous Materials (危険物) class of the substance and whether the storage or handling volume at the receiving site crosses its designated quantity threshold.
Does every imported solvent or paint shipment need a Hazardous Materials Handler on site?
Only once the quantity stored or handled at that site crosses the designated quantity (指定数量) set for that specific substance under the Cabinet Order Concerning Regulation of Hazardous Materials (危険物の規制に関する政令). Below that threshold, the license and facility permit generally are not required, but the threshold has to be checked against the actual substance and its water-solubility, not assumed from the product category.
Who applies for the storage permit, the importer or the warehouse operator?
The Hazardous Materials Handler (危険物取扱者) license attaches to the individual present at the storage site, and the facility permit is filed with the Local Fire Department (消防署) that has jurisdiction over that location. Aplash's role is identifying whether the threshold applies and advising on the permit requirement; the license and the filing itself sit with whoever operates the warehouse.
Conclusion
Flammable liquid imports into Japan carry two independent compliance layers: the transport-mode DG documentation that gets the shipment to Japan, and the Fire Services Act (消防法) framework that governs what happens to it once it is stored or handled domestically. Confirming DG classification for the flight or voyage says nothing about whether the receiving site has crossed a designated quantity threshold that requires a licensed handler and a storage permit. Treating the two as one step is the most common gap in flammable liquid import planning.
