Empty lotion bottles

Selecting the correct material is critical to prevent chemical reactions. PET (Polyethylene Terephthalate) is highly transparent and lightweight, ideal for water-based lotions, but may degrade with high essential oil content. HDPE (High-Density Polyethylene) offers excellent chemical resistance and is more durable for acidic or alkaline formulas. For luxury branding, Glass is the gold standard as it is non-reactive and 100% recyclable, though it increases shipping costs due to weight and fragility.

The pump is the most common point of failure. Ensure the dosage output (e.g., 0.2cc, 0.5cc) matches the product's viscosity to prevent clogging or splashing. Verify the neck finish size (e.g., 18/410, 24/410) for a leak-proof seal. High-quality pumps should feature a stainless steel spring that does not come into direct contact with the liquid (metal-free path) to avoid oxidation and contamination.

B2B buyers must ensure materials are BPA-free and comply with FDA or EU REACH regulations for cosmetic contact. Request ISO 9001 certification from the manufacturer to ensure batch consistency. For eco-conscious markets, look for PCR (Post-Consumer Recycled) plastic options and certifications like GRS (Global Recycled Standard) to meet sustainability mandates.

Request a vacuum leak test report from the supplier. A standard test involves placing the filled bottle in a vacuum chamber at -0.05MPa for 5 minutes to ensure no leakage occurs. Additionally, check for the presence of a PE liner or pressure-sensitive seal inside the cap to provide an extra layer of protection during high-altitude air transit.

The biggest risks are deformation during transit and high defect rates in pump springs. To mitigate this, specify double-wall corrugated export cartons and palletization. Always use a platform like Made-in-China.com to vet suppliers and utilize inspection services before the final balance payment is made.

Focus on volume-based pricing tiers; increasing an order from 5,000 to 10,000 units can often reduce the unit price by 15-20%. Negotiate for free silk-screen printing or labeling samples before mass production. For long-term partnerships, request Net-30 payment terms after the third successful transaction to improve your cash flow.

Since empty bottles are high-volume but low-weight (volumetric weight), Sea Freight (LCL or FCL) is the most economical choice. If you are ordering high-end glass bottles, ensure the Incoterms are CIF or DAP with comprehensive cargo insurance to cover potential breakage during the long-haul voyage.

Always conduct transactions through secured payment systems provided by reputable sourcing platforms like Made-in-China.com. Avoid direct wire transfers to unknown accounts. Ensure the Proforma Invoice (PI) clearly states the material grade, weight per bottle, and the specific HS Code (e.g., 392330 for plastic bottles) to avoid customs delays and incorrect duty applications.
