Total colour control: the Pantone 448C requirement for outer surfaces is absolute. There is no provision for matching shades, approximate colours, or equivalent standards. Manufacturers operating in multiple countries may not use a printing stock that merely approximates the specified colour. The standard is the Pantone swatch, not a colour description.
No stylistic variation in names: the requirements for brand and variant names are specific to normal weighted regular Lucida Sans. This excludes bold, condensed, expanded, italic, oblique, or any other typographic variation. Even a slightly different weight of the Lucida Sans font family would not comply.
Only the listed marks are permitted: the list of permitted marks in regulation 2.3.1 is exhaustive, not illustrative. Any mark not specifically authorised is prohibited. A decorative element, a certification mark, an environmental claim badge, or even a recycling symbol not falling within one of the permitted categories would be prohibited.
Wrappers are separately regulated: where packaging is wrapped in plastic or other material (regulation 2.5), the wrapper has its own rules. The wrapper may include a mark to conceal bar codes (regulation 2.5.1) and may include a tear strip (regulation 2.5.2). The specification for tear strips (position, width, colour) is precise.
Product appearance as well as packaging: Part 3 is often overlooked because attention focuses on packaging. However the Regulations also specify what the tobacco products themselves must look like. A cigarette with coloured paper, a flavour indicator stripe on the paper, or a gold filter tip would not comply.
Inserts are tightly controlled: regulation 2.6.2 permits inserts to avoid damage to tobacco products, but the insert is severely constrained. It must not constitute tobacco advertising, must not be false or misleading, must not imply a product is less harmful, and must not reference the brand or variant. A "product information" insert that promoted brand identity would breach these requirements.
