Do I Need Lab Analysis for My Nutrition Label?

Labs quote $400–800 per product for nutrition analysis, so this question matters. The short answer for most simple products: no — calculation from ingredient data is a legitimate basis for a label. Here's how the regulation actually works.

FDA checks outcomes, not methods

The compliance section (21 CFR 101.9(g)) defines how FDA verifies a label: they analyze a composite of product samples and compare it to your declared values. The tolerances:

• For "good" nutrients (protein, fiber, vitamins, minerals): the product must contain at least 80% of what you declared (100% for nutrients you added as fortification).
• For "watch" nutrients (calories, sugars, added sugars, fats, cholesterol, sodium): the product must not exceed declared values by more than 20%.

Nothing in the compliance framework requires that your declared values came from a laboratory. What matters is that the finished product lands inside those tolerances — and the regulation explicitly accommodates database-based labels, including a record-keeping requirement (your recipe and calculations, kept 2 years) for values like added sugars that analysis alone can't verify (101.9(g)(10)–(11)).

When calculation works well

Products where the finished item is essentially the sum of its ingredients: baked goods, jams, snack mixes, sauces, confections. USDA data covers the ingredients, your scale covers the amounts, and moisture loss is handled by weighing the finished batch.

When a lab earns its fee

• Frying — oil uptake is genuinely unpredictable from the recipe.
• Fermentation — sugars convert; the recipe no longer describes the product.
• Complex processing (extrusion, roasting to varying degrees) that changes composition.
• Nutrient content claims — if you print "high fiber" or "low sodium", you want analytical backup, because claims invite scrutiny and void small-business exemptions.

A sane workflow for a small producer

Start with a calculated label — it's what the large majority of small products use. Keep your recipe records. If you later scale into retail chains or make claims, commission a one-time analysis to confirm the calculation; if the two agree (they usually do for simple products), you've bought confidence, not a different label.
