Market size reports are useful if you treat them as a compass, not a map. Use them to confirm broad trends, but base your actual buying decisions on your own data—your sales history, customer feedback, and the specific regulatory environment you operate in. Cross-reference any big claim with primary sources like customs data or FDA filings, and you'll avoid the most common traps.

If you're expanding internationally, also keep an eye on regional regulatory changes, like the recent Singapore rules, because a market size number from last year might already be outdated.
