| Caffeine definition | Meaning of “U100” | “U100” is not an FDA-defined product category. For sourcing purposes, define it as 100 mg of caffeine per stated serving unless the specification says otherwise. | 1 serving = 100 mg caffeine; 2 servings = 200 mg. | Require the supplier to state caffeine content per piece, per serving, and per package in writing. |
| FDA daily guidance | Healthy-adult caffeine reference | The FDA states that, for most healthy adults, 400 mg of caffeine per day is an amount not generally associated with dangerous negative effects. | 400 mg ÷ 100 mg per candy = 4 U100 servings before counting other caffeine sources. | Use the 400 mg figure as a communication and risk-screening reference, not as a guarantee of safety for every consumer. |
| Caffeine stacking | Candy plus brewed coffee | The FDA notes that an 8 fl oz cup of coffee commonly contains approximately 80–100 mg of caffeine, although actual levels vary. | 95 mg coffee + 3 U100 candies (300 mg) = 395 mg total. | Show a combined-use example on product education materials and avoid presenting the candy as caffeine-free or risk-free. |
| Black coffee wholesale | Serving-size comparison | An 8 fl oz serving is a practical comparison point; caffeine in brewed coffee changes with bean type, roast, grind, brew ratio, and extraction method. | Four 8 fl oz servings at 80–100 mg each = approximately 320–400 mg. | Request the declared serving volume and a caffeine test result for the actual finished coffee product. |
| Laboratory verification | Actual caffeine concentration | The recipe or target specification should be confirmed by an appropriate laboratory method, such as high-performance liquid chromatography (HPLC). | Compare the laboratory result with the declared 100 mg per serving and record the tested lot number. | Obtain a recent certificate of analysis, sampling date, test method, result units, and acceptance criteria before approving a supplier. |
| Serving control | Piece weight and serving count | A declared caffeine amount must correspond to a clearly defined serving, such as one candy or a specified number of candies. | If one candy contains 100 mg, a package of 10 candies contains 1,000 mg total caffeine. | Check net weight, piece count, serving size, and caffeine per piece against the purchase specification and finished label. |
| Ingredient transparency | Caffeine source and formula | The supplier should identify whether caffeine is naturally present in coffee ingredients, added as caffeine, or supplied by another caffeine-containing ingredient. | Total caffeine should include both naturally occurring and added caffeine when applicable. | Request the complete ingredient declaration, allergen information, formulation version, and change-control procedure. |
| Label review | Net quantity and nutrition information | U.S. packaged-food labels generally require product identity, net quantity, ingredient list, allergen disclosure where applicable, and nutrition information, subject to applicable exemptions and product-specific rules. | Confirm that the serving size used for nutrition information matches the caffeine declaration and product specification. | Have the final artwork reviewed for the intended U.S. market before mass production or importation. |
| Consumer suitability | Target-audience restrictions | The 400 mg FDA reference is for most healthy adults. Individual sensitivity varies, and pregnant or breastfeeding consumers, children, adolescents, and people with certain medical conditions may require professional guidance or avoidance. | A 100 mg serving represents 25% of the 400 mg healthy-adult reference, but this percentage does not establish suitability for all groups. | Define age and usage controls, include appropriate cautionary language, and avoid marketing to children. |
| Shelf stability | Storage and best-by period | Coffee candy can be affected by moisture, heat, oxygen, and packaging performance; black coffee products may also require specific storage controls after opening. | Review accelerated or real-time stability data where available and verify packaging integrity during storage testing. | Set minimum remaining shelf life at delivery, storage temperature limits, lot coding, and damaged-carton procedures in the purchase agreement. |
| Supplier qualification | Quality and traceability documents | A responsible supplier should provide lot traceability, manufacturing specifications, food-safety controls, allergen controls, and documented corrective-action procedures. | Match the production lot, certificate of analysis, shipment record, and retained sample. | Approve suppliers only after document review, sample inspection, and a written process for handling deviations or formula changes. |
| Purchase specification | Commercial terms and acceptance criteria | The purchase order should define caffeine target, serving size, tolerances, package format, minimum shelf life, testing documents, and delivery conditions. | Example: target 100 mg caffeine per candy; acceptance requires the agreed laboratory range and matching lot documentation. | Use a signed product specification rather than relying only on a verbal “U100” description. |
