Exam scope and assessment notes
Cambridge IGCSE Business Studies 0450, 2026 syllabus, Version 2. Use the 2026 A*–G route; this qualification changes to 0264 for first assessment in 2027. Candidates are not assessed on constructing income statements or statements of financial position, nor on price-elasticity or exchange-rate calculations. Simple cash-flow forecast construction is assessed. Written practice is self-checked, not an official Cambridge grade; timed-paper evidence and human subject-teacher review remain outstanding.
Before you begin
- No previous marketing study is assumed. Identify the customer group, the business objective and the evidence in each situation before choosing a response.
Work on paper. Try each question before revealing help, and explain why your method works.

What you will learn
- Identify customer-protection purposes
- Explain effects of controls on marketing
- Avoid jurisdiction-specific legal assumptions
Marketing controls protect customers
The syllabus names misleading promotion and faulty goods as areas where legal controls protect customers. Customers need information that does not create a false impression and products that meet applicable requirements.
Specific laws and enforcement vary by country. This lesson explains the business purpose, not the legal wording of any single jurisdiction.
Compliance changes business practice
A business may need to substantiate claims, check product quality, correct inaccurate messages or stop selling a faulty product. These steps can add testing, review and correction costs.
Controls can also encourage customer confidence and fairer competition. The business should build checks into product and promotional decisions rather than treating compliance only as a late-stage obstacle.
Pause and explain
A business discovers that a product is faulty. What is one reason controls may affect its marketing?
Worked example
An advertisement says a drink contains 'zero sugar', but the ingredient list shows a sweetener and the product contains sugars. What should the business do before further promotion?
Show the worked solution
- The claim may mislead customers about the product.
- Check the product facts and applicable local requirements.
- Correct or remove a claim that cannot be substantiated.
Answer The business should verify the product composition and the local rules, then correct or remove any claim that creates a misleading impression. It should review future advertising before release.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A skincare advertisement claims a lotion 'works for everyone' without evidence. Explain the customer-protection concern and a safer marketing response.
Give me a hint
Consider whether the statement is substantiated and whether it implies a guarantee.
Compare my reasoning
- The absolute claim may create an unsupported impression.
- The business should check evidence and applicable rules.
- Use a narrower claim supported by valid product information.
The statement may mislead by promising universal results without evidence. The business should verify the claim against product data and local requirements, then use a specific, supportable description and explain relevant limitations.
Look for these in your work
- Risk identified
- Evidence and local rules checked
- Safer message proposed
Customers report that a batch of toys has a faulty part. Explain two marketing actions the business may need to review.
Give me a hint
The issue concerns both the product and customer communication.
Compare my reasoning
- The business may need to pause promotion or sales of the affected batch.
- It should give customers accurate information and an appropriate response.
- Investigate the fault and applicable customer-protection requirements.
The business may need to stop promoting or selling the affected batch and communicate clearly with customers about the issue and available remedy. It should investigate the fault and follow applicable local requirements before resuming marketing.
Look for these in your work
- Product action considered
- Communication action explained
- Compliance context included
A manager says legal controls only increase costs. Explain one possible business benefit and one cost of checking marketing claims before launch.
Give me a hint
Consider trust and correction risks alongside review resources.
Compare my reasoning
- Accurate claims can support customer confidence.
- Pre-launch review requires time or expertise.
- Early checks may prevent costly correction or disputes.
Claim checks can build customer confidence and reduce the chance of costly corrections or disputes, but they require staff time or expert review. The business should compare these costs with the risks and comply with the rules that apply locally.
Look for these in your work
- Business benefit described
- Cost acknowledged
- Trade-off balanced
Common mistakes
- Assuming a claim is acceptable because a competitor uses it
- Treating a disclaimer as a cure for a misleading headline
- Assuming the same detailed law applies in every country
