How do you prevent leakage for droppers and pumps during UK e-commerce shipping?

Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

• Leakage prevention starts at the design phase.
• For droppers, we specify precision-molded PP/PE tips with silicone gaskets and conduct torque testing on caps to ensure consistent sealing under pressure changes during air freight.
• Pumps are selected based on actuator force and dip-tube length to avoid backflow, with samples tested in climate chambers simulating UK warehouse humidity.
• Our standard MOQ for custom packaging is 10,000 units, which allows cost-effective tooling for leak-proof components.
• Sampling typically takes 4-6 weeks, including 3D prototyping and fit checks with your formula’s viscosity.
• Production lead time is 8-12 weeks post-approval, factoring in batch-wise microbial hold-time validation and secondary packaging like bubble wrap or carton inserts for shock absorption.
• We support full documentation for UK compliance, including CPSR and CLP labels, but final regulatory approval is your responsibility.
• Key tests include 24-hour inverted storage, transit drop tests from 1.2 meters, and pressure differential simulations to mimic e-commerce shipping conditions.
