Detergent powder

Buyers should focus on the Active Matter (Surfactant) content, which typically ranges from 10% to 25% depending on the grade; higher percentages generally equate to better cleaning power. Ensure the formula includes builders like Zeolite or STPP for water softening, protease/amylase enzymes for organic stain removal, and optical brighteners for fabric vibrancy. For high-efficiency (HE) machines, prioritize low-suds formulas to prevent mechanical malfunction.

Request Material Safety Data Sheets (MSDS) and Certificate of Analysis (COA) for every batch. Ensure compliance with regional standards such as REACH (EU) for chemical safety or detergent labeling acts in the US. If targeting eco-conscious markets, verify biodegradability certifications and ensure the product is phosphate-free to meet environmental regulations in many Western countries.

Detergent powder is sensitive to moisture; therefore, multi-layer PE/PP laminated bags or moisture-proof woven bags are essential. For retail-ready goods, check the sealing integrity to prevent leakage during transit. For industrial bulk, Jumbo Bags (500kg-1000kg) with inner liners are the most cost-effective. Always confirm that the packaging weight tolerance is within ±1%.

Detergent powder comes in low-density (tower-blown) and high-density (concentrated) forms. High-density powder occupies less container space, significantly reducing ocean freight costs per ton. However, low-density powder provides a larger visual volume, which is often preferred in specific consumer retail markets. Calculate your landed cost based on the density-to-volume ratio.

Always conduct a Pre-Shipment Inspection (PSI) through third-party agencies like SGS or Intertek. Have them perform a random sampling test to verify the Active Matter percentage and moisture content (which should ideally be below 5-10%) before the balance payment is made. This prevents suppliers from 'padding' the weight with cheap fillers like sodium sulfate.

Focus on the formula transparency. Instead of asking for the 'lowest price,' provide a target specification sheet (e.g., 15% Active Matter, Lemon Scent, Blue Speckles). Request tiered pricing based on 1x20GP vs. 1x40HQ containers, as full container loads (FCL) are vital for heavy chemical commodities to minimize per-unit logistics overhead.

Detergent powder is generally classified as non-hazardous, but it must be kept cool and dry. Ensure the container is inspected for holes or rust before loading to prevent water ingress. Use desiccant bags inside the container to manage humidity during long sea voyages, especially when crossing the equator, to prevent the powder from caking or lumping.
