Plastic tumbler

Buyers should distinguish between PP (Polypropylene), AS (Acrylonitrile Styrene), and Tritan™. PP is BPA-free and cost-effective but less transparent. AS offers high clarity and rigidity but is more brittle. Tritan™ is the premium choice, offering glass-like transparency, extreme durability, and is 100% dishwasher safe, making it ideal for high-end retail.

For the US market, compliance with FDA 21 CFR is essential. For the EU, products must meet LFGB (Lebensmittel- und Futtermittelgesetzbuch) and EU Regulation No. 10/2011. Ensure the supplier provides BPA-Free test reports from accredited third parties like SGS, TUV, or Intertek to avoid customs seizures.

Double-walled construction is designed for condensation prevention and basic thermal retention. Verify the ultrasonic welding quality of the inner and outer layers; poor welding leads to water leakage into the vacuum space during washing. Request a leak-proof test report and a thermal insulation curve (typically 2-4 hours for plastic) before placing bulk orders.

For complex logos, UV Printing or Heat Transfer Printing offers vibrant colors. For long-term durability, Silk Screen Printing is cost-effective for large volumes, while In-Mold Labeling (IML) provides the highest wear resistance as the graphic is integrated into the plastic itself. Always confirm the ink's lead-free and non-toxic status.

Plastic tumblers are prone to scratching and cracking. Require individual bubble bag packaging or egg-crate dividers in the master carton. Ensure the outer cartons meet the ISTA 3A drop test standard and specify the use of 5-layer corrugated export-grade cardboard to prevent crushing during stacking in containers.

Focus on Tiered Pricing based on volume; for orders over 5,000 units, aim for a 10-15% discount. Negotiate for free mold modifications if you are doing a custom shape. Use the Secured Trading Service on Made-in-China.com to ensure payment is only released after the Bill of Lading (B/L) is uploaded and verified.

Conduct a Random Sampling Inspection (AQL 2.5/4.0). Key checks include the Smell Test (no pungent plastic odor), Lid Fitment Test (ensure threads align and seals are airtight), and Color Consistency against the approved golden sample. Any burrs or sharp edges should be flagged as critical defects.

Check the HS Code (typically 3924.10) for your specific country to determine import tariffs. Be aware of Single-Use Plastic (SUP) bans in regions like the EU; ensure your tumblers are marketed and certified as 'Reusable' with a documented minimum life cycle (e.g., 500 washes) to comply with environmental regulations.
