Pet bottle 5ml

When sourcing 5ml PET bottles, ensure the material is 100% virgin PET (Polyethylene Terephthalate) to guarantee high transparency, chemical resistance, and BPA-free safety. For pharmaceutical or cosmetic use, verify the wall thickness (typically 0.5mm to 1.0mm) to ensure the bottle is squeeze-resistant yet durable enough to prevent cracking during transit.

For food and cosmetic applications, products must comply with FDA (U.S. Food and Drug Administration) or EU Regulation (EC) No 1935/2004 standards. If used for pharmaceuticals, ensure the supplier holds an ISO 15378 certification, which specifically addresses primary packaging materials for medicinal products. Always request a Declaration of Compliance (DoC) and Heavy Metal Migration test reports.

The closure must match the neck finish (e.g., 18/410 or 20/410). For essential oils or medicines, prioritize Child-Resistant Caps (CRC) and Tamper-Evident Rings to ensure consumer safety. For eye drops or e-liquids, specify the dropper tip precision (e.g., 0.05ml per drop) and ensure a leak-proof seal through vacuum leak testing.

Despite the small size, you can opt for UV coating, silk-screen printing, or hot stamping. For branding, custom masterbatch coloring (opaque or translucent) is available, but note that custom colors usually require a higher MOQ (Minimum Order Quantity) compared to clear or white bottles. Ensure the supplier provides 3D mockups before mold production.

PET bottles are lightweight and susceptible to heat deformation and pressure. Ensure the supplier uses 5-layer corrugated export cartons with PE inner bags to prevent dust contamination. For sea freight through tropical zones, request temperature-controlled containers or ensure the bottles are not stacked at the top of the container where heat accumulates.

Start by requesting a tiered pricing structure (e.g., 10k, 50k, and 100k units). Since 5ml bottles have low unit value, shipping costs often exceed product value; therefore, negotiate FOB (Free On Board) terms to maintain control over logistics. Mention your long-term procurement plan to secure a lower MOQ for the initial trial order.

Be aware of Plastic Tax regulations in regions like the UK and EU, which may apply if the bottles do not contain at least 30% recycled content (rPET). Verify the HS Code (typically 392330) with your local customs broker to confirm import duties and anti-dumping duties that might apply to plastic products from specific manufacturing hubs.
