The GL was issued by the Director-General of the Pharmaceutical Safety and Environmental Health Bureau on September 25, 2018. The date of issuance was not, however, the date on which everything took effect. Section 4.8 establishes a two-stage implementation timeline, each stage calibrated to the type of change it requires.
Implementation timelines are not administrative boilerplate. The two dates here reflect a deliberate choice to separate obligations that can be satisfied through individual behavior change from those that require new organizational structures. Asking companies to establish committees and build supervisory departments overnight would make the GL unenforceable in practice.
01April 1, 2019 — the GL's main provisions take effect
Chapter 1 (basic principles), Chapter 3 (representative obligations), and Chapter 4 (supplementary provisions) became effective on April 1, 2019.
From that date, representatives were bound by Chapter 3's conduct standards: what they may say, what materials they may use, how they must respond to HCP questions, and what activities are prohibited. The Chapter 4 special provisions—covering outsourcees, wholesalers, HCP responsibilities, and the application date itself—also became operative on this date.
So what: Representative-level conduct standards were the first things to apply. From April 2019, a representative who used unapproved materials, made unsubstantiated claims, or engaged in prohibited conduct was in violation of the GL.
So why: Roughly six months elapsed between the issuance date (September 2018) and the first effective date (April 2019). This interval was designed to allow companies to train their field forces. Behavior change without training produces inadvertent violations; the lead time made informed compliance possible.
02October 1, 2019 — Chapter 2 and supervisory department requirements take effect
The organizational obligations under Chapter 2 (company responsibilities) and all provisions relating to the supervisory department became effective on October 1, 2019.
Chapter 2's requirements include: establishing a Review and Supervisory Committee, defining its composition and authority, building a pre-review process for all materials, implementing training programs for representatives, and maintaining records of activities and reviews. Each of these requires structural decisions—budget approval, staffing, drafting of internal policies, potentially engagement of external experts.
So what: Companies had until October 2019 to have their committees and supervisory departments operational. The April–September 2019 window was a final implementation phase for organizational buildout, not an optional buffer.
So why: Committee establishment may require recruiting external experts, revising internal regulations, and securing budget—none of which can be done overnight. Separating conduct obligations (April) from structural obligations (October) decomposed an otherwise unmanageable change into two achievable steps.
03What the two-stage design signals
The decision to split application into two dates carries a policy message.
Field behavior first, organizational infrastructure second—this sequencing prioritizes stopping problematic conduct while allowing more time for the structural changes that require organizational process. It also communicates that neither deadline is negotiable: April 1 and October 1 were hard cutoffs, not targets.
After October 1, 2019, operating without a committee or without a functioning supervisory department is a GL violation, not a compliance gap to be remedied at the next planning cycle.
So what: The two deadlines determined every company's implementation schedule. "We are working on the committee structure" was an acceptable statement in mid-2019; it was a compliance problem from October 2019 onward.
So why: Without hard deadlines, preparation periods extend indefinitely. The explicit dates converted the GL from a statement of intent into an enforceable obligation. They also signal that the Ministry treated the structural requirements—not just the conduct standards—as genuinely mandatory.
Section 4.8 encodes two things at once: a concession to implementation reality, and a clear announcement that the concession is time-limited. Six months to train representatives, twelve months to build the organizational infrastructure—these windows were generous enough to be achievable and firm enough to be binding. From October 2019 onward, Chapter 2's obligations are in full effect, and the absence of a functioning committee or supervisory department is a violation, not a transition.
