When a variation changes certificate particulars a new certificate is issued dated from its issue but keeping the original expiry date (Prakas 4206, Art. 7)
Under Article 7 of Prakas 4206, if a variation affects information printed on the visa-registration certificate, a new certificate is issued counted from its own date of issue while retaining the original expiry date, and the original certificate must be returned with the application; variations that do not affect certificate particulars are filed with a copy of the certificate.
- Applies to products within the prakas' definition of pharmaceutical products, which includes medical devices and reagents (Art. 4).
English gist: copy of the certificate where the variation does not touch certificate particulars; where it does, a new certificate is issued from its issue date but keeps the same expiry date, and the original certificate must be attached.
