| Formula compatibility | Whether pump materials and product-contact parts suit the skincare formula, including its oils, solvents, viscosity, and active ingredients. | Compatibility testing using the intended formula and packaging assembly; check for leakage, swelling, cracking, discoloration, odor, or changes in pump function. | Request test conditions and results for the actual formula. Compatibility can vary by formula and component material. |
| Dispensing performance | Output per actuation, consistency across repeated strokes, priming behavior, and suitability for the product’s viscosity. | Ask for the nominal dosage, measurement method, sample results, and performance after repeated dispensing. | Compare samples against the target dose and acceptable variation agreed for the product; do not rely on nominal output alone. |
| Leakage and closure | Resistance to leakage during storage, handling, and shipment, including when the pump is locked or fitted with a protective cap. | Review documented leak tests and sample the finished pack in the intended orientation and transport conditions. | Confirm the test setup, duration, and acceptance criteria. A test result applies to the tested pack configuration. |
| Material and component information | Materials used in the actuator, dip tube, bottle interface, seals, and other product-contact components. | Request a component and material specification, including material identification for plastics and metal parts where applicable. | Check that documentation covers the complete assembly and matches the production sample; material selection alone does not establish formula compatibility. |
| Quality management | Documented controls for production, inspection, nonconforming parts, traceability, and corrective actions. | Review the supplier’s quality-management documentation, inspection records, and relevant audit or certification scope. | Verify the certificate issuer, validity, and scope if certification is claimed; assess production controls separately from certification status. |
| Production capacity and continuity | Ability to meet forecast demand, handle repeat orders, and communicate capacity constraints or supply interruptions. | Request a capacity statement, production schedule assumptions, and a documented continuity or contingency plan. | Compare stated capacity and lead time with the buyer’s forecast and launch schedule. Confirm figures in a current quotation. |
| Customization and tooling | Options for actuator shape, output, color, dip-tube length, decoration, and custom tooling. | Review drawings, sample parts, tooling terms, color approval process, and change-control procedures. | Clarify ownership, maintenance, replacement, and approval requirements for any custom tooling before placing an order. |
| Regulatory and market documentation | Availability of material, safety, and product documentation needed for the buyer’s target markets and intended use. | Request applicable declarations, test reports, and supporting technical documents; confirm their scope and revision dates. | Requirements vary by market and product. Have the responsible compliance team confirm which documents apply. |
| Sustainability and end-of-life design | Material choices, component separability, recycled-content claims, and compatibility with relevant local collection and recycling systems. | Request component-level material information and substantiation for any recycled-content or recyclability claim. | Evaluate the complete pack, not just the bottle. Pumps can combine multiple materials that may affect sorting and recycling. |
| Commercial terms and service | Minimum order quantity, lead time, sample availability, payment terms, complaint handling, and after-sales support. | Compare current written quotations, sample timelines, service contacts, and stated procedures for quality claims. | Record each term in the purchase agreement; minimum quantities and lead times are supplier- and order-specific. |
