Capsule detergent

Buyers should focus on the active matter content, which typically ranges from 60% to 80% for high-quality pods. Ensure the PVA (Polyvinyl Alcohol) film thickness is between 75-85 microns to balance rapid dissolution in water with physical durability during transport. Additionally, verify the enzyme stability (protease, amylase, cellulase) to ensure effective stain removal across various water temperatures.

For the US market, products must comply with ASTM D7996 for liquid laundry detergent packets. In the EU, adherence to REACH regulations and CLP (Classification, Labelling and Packaging) is essential. Ensure the packaging features child-resistant closures (e.g., double-action zippers or locking tubs) and contains a bittering agent (like Denatonium Benzoate) to prevent accidental ingestion.

Request a dissolution test report; high-quality pods should fully dissolve in cold water (approx. 15°C) within 2 to 4 minutes without leaving residue. For stability, the pods must withstand a pressure test of at least 300N to prevent leakage during stacking and should remain stable under high humidity conditions (30°C at 80% RH) without sticking together.

Professional suppliers on Made-in-China.com usually offer customization for chamber configurations (single, 3-in-1, or 4-in-1), fragrance profiles (long-lasting scent technology), and color matching. Discuss MOQ requirements for private labels, which typically start at 10,000 to 50,000 units depending on the complexity of the packaging design.

The main risks are leakage and moisture damage. Ensure the supplier uses heavy-duty 5-layer corrugated outer cartons and internal moisture-proof barriers. It is highly recommended to use sea freight with temperature-controlled containers if crossing tropical zones, as extreme heat can soften the PVA film and cause mass leakage.

Negotiate based on raw material index pricing (e.g., surfactant market rates). For first-time orders, use Secure Payment services or Letter of Credit (L/C). Aim for a 30% deposit and 70% balance against the Bill of Lading (B/L). Always request a pre-shipment inspection (PSI) by a third party like SGS or Intertek to verify the quantity and pod integrity.

Detergents are often classified under HS Code 3402. You must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. Ensure the ingredient list is fully disclosed in English to avoid delays during customs clearance, especially regarding restricted surfactants or phosphates.

Prioritize Audited Suppliers who have undergone on-site verification. Check their export history to your specific region and look for ISO 9001 or GMP (Good Manufacturing Practice) certifications. Reviewing their R&D capabilities is also vital if you require specialized formulas like 'eco-friendly' or 'sensitive skin' variants.
