Hong Kong Dangerous Drugs Wholesale Dealer Licence: Part I and Part II Requirements

Quick answer

Do I need a separate licence for dangerous drugs wholesale dealing in Hong Kong?

Yes. Wholesale dealing in dangerous drugs in Hong Kong requires a Wholesale Dealer's Licence to Supply Dangerous Drugs under the Dangerous Drugs Ordinance (Cap. 134), administered by the Department of Health (DH) Drug Office through the Pharmacy and Poisons Board (PPB). This licence is additive: you must already hold—or apply concurrently for—a base Wholesale Dealer Licence (WDL) for pharmaceutical products and poisons under the Pharmacy and Poisons Ordinance (Cap. 138). If your product scope includes Part I dangerous drugs listed in the First Schedule to Cap. 134, you need the Part I dangerous drugs WDL track. If you deal only in Part II dangerous drugs, you need the Part II track. Psychotropic drugs and Part I dangerous drug transactions must be handled by a registered pharmacist. Applications are submitted via the Drug Office e-form portal (Guidance Notes pharmdd.pdf, May 2025). DH's performance pledge targets two months for wholesaler licence processing. General enquiries: 3107 2194 or pharmgeneral@dh.gov.hk. Licensing office: Room 2001–2002, 20/F, Dah Sing Financial Centre, 248 Queen's Road East, Wan Chai.

Who this applies to

This guide is for companies and regulatory teams planning wholesale supply of dangerous drugs in Hong Kong—not retail pharmacy dispensing or manufacturer licensing.

RoleRelevance
Pharmaceutical wholesalersexpanding into opioids, controlled substances, or psychotropicsMust layer Cap. 134 dangerous drugs WDL on top of Cap. 138 WDL
Import/export operatorsmoving dangerous drugs across Hong Kong bordersDangerous drugs WDL is prerequisite to import/export permits under Cap. 134
Compliance and QA managersResponsible for PPB Code of Practice storage, cold chain, and record-keeping
Registered pharmacistsMandatory involvement for Part I and psychotropic wholesale transactions
New market entrantsMust map product lists against DDO First Schedule Part I vs Part II before applying

This article covers the dangerous drugs wholesale dealer licence track. It complements—but does not replace—guides on the base pharmaceutical WDL (wdl-hong-kong, wdl-hong-kong-2), GMP manufacturer licensing (gmp-compliance-hong-kong), and import/export permit workflows (import-export-regulations).

Three-layer licensing model: Cap. 138 base plus Cap. 134 add-ons

Hong Kong separates wholesale licensing by legal instrument. The Drug Office Guidance Notes on Wholesale Dealer's Licence to Supply Dangerous Drugs (pharmdd.pdf, May 2025) describe a layered model:

LayerLegal basisLicence / permitWhen required
1 — Base wholesalePharmacy and Poisons OrdinanceCap. 138Wholesale Dealer Licence (WDL)for pharmaceutical products and poisonsAll wholesale dealing in poisons and pharmaceutical products
2 — AntibioticsCap. 138 (antibiotics provisions)Antibiotics PermitIf product scope includes antibiotics
3 — Dangerous drugsDangerous Drugs OrdinanceCap. 134Wholesale Dealer's Licence to Supply Dangerous Drugs(Part I and/or Part II)If product scope includes substances in the DDO First Schedule

You cannot hold a dangerous drugs WDL without the Cap. 138 base WDL. An antibiotics permit, where applicable, is a separate add-on between layers 1 and 3.

Cap. 138 WDL (pharmaceutical products and poisons)

The base WDL authorises wholesale dealing in poisons and pharmaceutical products registered or otherwise lawfully supplied under Cap. 138. Guidance for this licence is in pharmwp.pdf (Guidance Notes: Wholesale Dealer Licence). Application is via the Application e-Form for Wholesale Dealer Licence of Pharmaceutical Products on DH's useful forms page. Holders must comply with the PPB Code of Practice for Holders of Wholesale Dealer Licence (PPB_COP_WDL.pdf), covering premises standards, storage, distribution records, and quality systems.

Cap. 134 dangerous drugs WDL (Part I or Part II)

Dangerous drugs are controlled under the Dangerous Drugs Ordinance (Cap. 134). The First Schedule divides substances into Part I and Part II dangerous drugs. Wholesale supply requires a dedicated Wholesale Dealer's Licence to Supply Dangerous Drugs—distinct from the Cap. 138 WDL certificate.

  • Part I dangerous drugs → apply for the Part I dangerous drugs WDL (in addition to base WDL)
  • Part II dangerous drugs only → apply for the Part II dangerous drugs WDL (in addition to base WDL)
  • Both Part I and Part II → scope both tracks on your dangerous drugs WDL application

Import and export of dangerous drugs additionally require Import Certificate, Import and Export Licence, Removal Licence, or Diversion Licence forms listed under Drugs Dealers on DH's forms page—these are separate from the wholesale dealer licence itself.

Part I vs Part II dangerous drugs: comparison table

Understanding whether your product portfolio falls under Part I or Part II determines licence scope, pharmacist requirements, and storage controls.

Map every SKU in your wholesale catalogue against the current DDO First Schedule before filing. Product reclassification or schedule amendments can change which Part applies.

Pharmacist requirement for Part I and psychotropic drugs

The pharmdd.pdf guidance (Section I.4) states that psychotropic drugs and Part I dangerous drugs wholesale transactions must be handled by a registered pharmacist. This is an operational compliance requirement—not merely a staffing recommendation.

Practical implications:

  1. Named pharmacist — Your organisation must have a registered pharmacist available to supervise and conduct Part I and psychotropic wholesale dealings, including order verification, release, and record sign-off.
  2. Transaction-level control — Wholesale supply of Part I substances without pharmacist involvement breaches licensing conditions.
  3. Staff register — Application appendices require a Director and staff list identifying responsible persons, including pharmacists where applicable.
  4. Distinction from retail pharmacy — An Authorized Seller of Poisons (pharmacy premises) licence is a retail concept under Cap. 138. Wholesale dangerous drugs dealing requires the WDL stack described here, not a dispensary registration alone. See pharmacy-vs-medicine-store-differences for retail vs wholesale distinctions.

Part II-only wholesalers still need robust controlled-substance procedures but are not subject to the same mandatory pharmacist transaction rule as Part I.

Step-by-step application workflow

Follow this sequence when applying for—or varying—a dangerous drugs wholesale dealer licence.

Step 1: Confirm product scope against DDO First Schedule

  1. List every product your company will wholesale.
  2. Classify each as Part I, Part II, or non-dangerous-drug (Cap. 138 only).
  3. Flag psychotropic products for pharmacist workflow planning.
  4. Flag antibiotics for a separate Antibiotics Permit application.

Step 2: Secure or confirm base Cap. 138 WDL

If you do not already hold a pharmaceutical WDL:

  1. Download pharmwp.pdf (Guidance Notes: Wholesale Dealer Licence).
  2. Complete the Application e-Form for Wholesale Dealer Licence of Pharmaceutical Products on DH useful forms.
  3. Prepare premises documentation per pharmwp checklist and PPB_COP_WDL.pdf.

Apply for base WDL and dangerous drugs WDL concurrently if timelines require both before operations begin.

Step 3: Apply for Antibiotics Permit (if applicable)

If antibiotics are in scope, submit the Application e-Form for Antibiotics Permit via the same DH forms portal. Contact: 3107 2194, pharmgeneral@dh.gov.hk.

Step 4: Apply for Wholesale Dealer's Licence to Supply Dangerous Drugs

  1. Download pharmdd.pdf (May 2025 edition) from the Drug Office guidelines page.
  2. Complete the Application e-Form for Wholesale Dealer's Licence to Supply Dangerous Drug on DH useful forms.
  3. Specify Part I, Part II, or both on the application according to product scope.
  4. Attach required appendices (see Key documents section below).
  5. Submit via the online e-form portal with digital signature (digital certificate or iAM Smart).

Step 5: Premises and storage readiness

Ensure wholesale premises—and any external warehouses declared on the application—meet:

  • Dangerous drugs storage security requirements in pharmdd.pdf
  • Cold chain requirements where temperature-controlled products are handled (cold room checklist in appendices)
  • PPB Code of Practice standards for WDL holders

Step 6: Await Drug Office assessment

DH's performance pledge commits to processing permits, licences, and certificates for wholesalers within two months under normal circumstances. Complex applications, incomplete submissions, or premises inspection findings may extend timelines.

Step 7: Post-grant compliance

After licence grant:

  1. Operate only within the licensed product scope (Part I / Part II).
  2. Maintain distribution and stock records per PPB COP.
  3. Apply for import/export/removal licences before cross-border dangerous drugs movements.
  4. Renew licences before expiry and notify DH of material changes (directors, staff, premises, warehouses).

Key documents and what they must contain

The pharmdd.pdf application package includes several appendices. Prepare each before submitting the e-form.

Application form and declarations

  • Completed Application e-Form for Wholesale Dealer's Licence to Supply Dangerous Drug
  • Declaration forms as specified in pharmdd.pdf — signed by authorised company representatives

Director and staff list

  • Names, roles, and qualifications of directors and key staff
  • Identification of registered pharmacist(s) responsible for Part I and psychotropic dealings
  • Updated list required when personnel change

Premises and warehouse documentation

  • Floor plan and address of wholesale premises
  • External warehouse details if storage occurs off-site (separate appendix in pharmdd.pdf)
  • Evidence that premises meet dangerous drugs security and storage standards

Cold room checklist (where applicable)

If your product scope includes temperature-sensitive dangerous drugs:

  • Complete the cold room checklist appendix in pharmdd.pdf
  • Document monitoring, calibration, and alarm procedures
  • Align with PPB COP cold chain expectations

Base WDL and antibiotics permit evidence

  • Copy of current Cap. 138 Wholesale Dealer Licence, or concurrent application reference
  • Antibiotics Permit copy if antibiotics are in the product portfolio

Quality and operating procedures

  • Standard operating procedures for receipt, storage, picking, and dispatch of dangerous drugs
  • Stock record and order traceability systems per PPB Code of Practice

Pre-application checklist

Use this checklist before submitting the dangerous drugs WDL e-form:

  • Product list mapped to DDO First Schedule Part I and/or Part II
  • Base Cap. 138 WDL held or applied concurrently
  • Antibiotics Permit applied for if antibiotics are in scope
  • Registered pharmacist identified for Part I / psychotropic handling
  • pharmdd.pdf (May 2025) and PPB_COP_WDL.pdf reviewed
  • Premises and any external warehouses meet storage and security requirements
  • Cold room checklist completed if cold chain products are included
  • Director and staff list appendix prepared
  • Declaration forms signed by authorised signatories
  • E-form submission tested with digital certificate or iAM Smart
  • Import/export permit strategy confirmed for cross-border dangerous drugs (import-export-regulations)

Common pitfalls

  1. Applying for dangerous drugs WDL without base WDL — Cap. 134 licence is always additive to Cap. 138. Drug Office will not grant dangerous drugs wholesale authority alone.
  2. Wrong Part I / Part II scope — Listing Part II only when Part I products are in the catalogue creates unlicensed dealing exposure. Audit SKUs against the current First Schedule.
  3. No pharmacist for Part I transactions — Operating Part I wholesale without registered pharmacist involvement breaches pharmdd.pdf Section I.4.
  4. Confusing wholesale WDL with retail pharmacy licence — A pharmacy premises registration (Authorized Seller of Poisons) does not authorise wholesale dangerous drugs supply.
  5. Omitting external warehouses — Off-site storage must be declared in the external warehouse appendix. Undeclared storage sites invalidate compliance.
  6. Importing before licence grant — Dangerous drugs import certificates and export licences require a valid wholesale dealer licence. Sequence import permits after licensing.
  7. Ignoring PPB Code of Practice updates — WDL holders must follow PPB_COP_WDL.pdf for storage, records, and distribution. Dangerous drugs add stricter controls on top.
  8. Incomplete cold chain documentation — Temperature-sensitive dangerous drugs without a completed cold room checklist delay approval.

FAQ

Do I need a separate licence for dangerous drugs in Hong Kong?

Yes. Wholesale supply of dangerous drugs requires a Wholesale Dealer's Licence to Supply Dangerous Drugs under DDO Cap. 134, in addition to your base Wholesale Dealer Licence under Cap. 138. Apply via the Drug Office e-form portal; guidance is in pharmdd.pdf (May 2025).

What is the difference between pharmaceutical WDL and dangerous drugs WDL?

The pharmaceutical WDL (Cap. 138) authorises wholesale dealing in poisons and pharmaceutical products. The dangerous drugs WDL (Cap. 134) is a separate add-on authorising wholesale of Part I and/or Part II substances listed in the DDO First Schedule. You need both if your catalogue includes dangerous drugs.

When is a registered pharmacist required for wholesale dealing?

A registered pharmacist must handle transactions involving Part I dangerous drugs and psychotropic drugs, per pharmdd.pdf Section I.4. Part II-only wholesale scope does not trigger the same mandatory pharmacist transaction rule, though qualified oversight remains best practice.

How long does the Drug Office take to grant a dangerous drugs wholesale licence?

Under DH's performance pledge, permits and licences for wholesalers are processed within two months in normal circumstances. Incomplete applications, premises inspection requirements, or scope complexity may extend the timeline. Enquiries: 3107 2194.

Can I apply for base WDL and dangerous drugs WDL at the same time?

Yes. Concurrent applications are common for new entrants. Specify Part I and/or Part II scope on the dangerous drugs e-form and ensure all appendices—director and staff list, declarations, warehouse details, cold room checklist—are complete for both tracks.

What is the difference between Part I and Part II dangerous drugs?

Part I and Part II are divisions of the First Schedule to the Dangerous Drugs Ordinance (Cap. 134). Part I substances carry stricter wholesale controls, including mandatory pharmacist handling. Part II substances require the Part II dangerous drugs WDL track but with different operational rules. Classify each product against the current schedule before applying.

Do I need import licences in addition to the wholesale dealer licence?

Yes, for cross-border movement. A dangerous drugs wholesale dealer licence authorises domestic wholesale dealing. Import Certificate, Import and Export Licence, Removal Licence, and Diversion Licence applications under Cap. 134 are separate forms on DH's useful forms page and require a valid wholesale licence first.

Where do I submit the application and who do I contact?

Submit the Application e-Form for Wholesale Dealer's Licence to Supply Dangerous Drug via DH useful forms. General enquiries: 3107 2194, pharmgeneral@dh.gov.hk. Licensing office: Room 2001–2002, 20/F, Dah Sing Financial Centre, 248 Queen's Road East, Wan Chai.
