Small plastic products

You should select materials based on the product's end-use. For food-contact items, ensure the use of BPA-free Polypropylene (PP) or Polyethylene (PE). For high-precision technical parts, Acrylonitrile Butadiene Styrene (ABS) or Polycarbonate (PC) are preferred due to their dimensional stability and impact resistance. Always request a Material Data Safety Sheet (MSDS) to verify chemical composition.

Precision is determined by the mold quality and tolerance control. For small parts, specify a tolerance range (e.g., +/- 0.05mm). Ensure the supplier uses high-speed injection molding machines for consistency and check for common defects like flash, sink marks, or short shots. Requesting a First Article Inspection (FAI) report before mass production is critical.

Compliance varies by region: for the US, FDA approval is required for food-related items and CPSIA for children's products. For the EU, products must adhere to REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and RoHS if the plastic is used in electronic components. Ensure the supplier provides third-party lab test reports (e.g., SGS or TUV).

Customization is cost-effective only when the Total Order Volume justifies the Mold Tooling Cost. For small items, look for suppliers on Made-in-China.com that offer multi-cavity molds to reduce the per-unit cost. If your volume is low, consider using existing public molds to avoid high upfront engineering fees.

Implement a staged inspection strategy. Conduct a During Production (DUPRO) inspection to catch defects early and a Pre-Shipment Inspection (PSI) to verify the final quantity and quality. Use Trade Assurance or secure payment terms to ensure funds are only released upon successful inspection results.

Focus on the Price-to-Weight ratio and Raw Material Index. Since plastic prices fluctuate with oil markets, negotiate a price adjustment formula for long-term contracts. Additionally, clarify mold ownership in writing; ensure that you own the mold if you paid the tooling fee, allowing you to move it if the supplier fails to meet KPIs.

Small plastic items are prone to crushing or scratching. Insist on double-walled corrugated export cartons and the use of polybags or bubble wrap for individual units. For high-volume shipments, use palletization with shrink wrap to prevent box deformation during sea freight transit.

Check the HS Code (typically Chapter 39) for your specific product to determine import duties. Be aware of Anti-Dumping Duties (ADD) that some countries impose on specific plastic categories. Consult with a professional freight forwarder on Made-in-China.com to navigate Section 301 tariffs if shipping to the United States.
