65 humic sodium humate manufacturers

Buyers must prioritize the Humic Acid content (dry basis ≥ 65%) and the Water Solubility (typically ≥ 90-95%). For industrial or agricultural applications, the pH value (usually 8.0-11.0) and moisture content (≤ 15%) are critical. If used in aquaculture or animal feed, ensure the heavy metal content (Pb, As, Cd) is well within international safety limits.

Sodium Humate is available in powder, crystal, and flake forms. Flakes and crystals are often preferred for their low dust levels and ease of handling in large-scale agricultural mixing. Powder offers faster dissolution rates but requires moisture-proof packaging to prevent caking during long-term sea transit.

For agricultural use, look for OMRI (Organic Materials Review Institute) or REACH (for EU markets) compliance. If the product is intended for animal feed additives, the supplier should hold ISO 22000 or GMP+ certifications to ensure feed safety and traceability. Always request a Certificate of Analysis (COA) for every batch.

It is widely used as a soil conditioner to improve nutrient uptake, a ceramic binder to increase green strength, and a water purifier in aquaculture to absorb heavy metals. In the livestock industry, it serves as a feed additive to promote intestinal health and improve immunity.

The primary risk is quality inconsistency between the sample and the bulk order. Because humic substances are derived from natural leonardite, the purity levels can fluctuate. To mitigate this, use third-party inspection services (like SGS or Intertek) to test the humic acid content before the balance payment is made.

Focus on Tiered Pricing based on volume; for 65 Humic Sodium Humate, a Full Container Load (FCL) usually yields a 10-15% discount compared to LCL. Additionally, negotiate for customized packaging (25kg PP bags with PE liners) to ensure product stability during humid sea voyages.

Sodium Humate is generally classified as non-hazardous, but you must ensure the supplier provides a Material Safety Data Sheet (MSDS) and a Non-Hazardous Cargo Declaration to avoid customs delays. For transaction security, utilize secured payment terms and prioritize Diamond Members or Audited Suppliers on Made-in-China.com to ensure business legitimacy.

Be aware of anti-dumping duties or specific environmental regulations regarding mined minerals in your destination country. Ensure the Harmonized System (HS) Code (typically 382499 or 310590) is correctly declared to avoid misclassification fines and to benefit from applicable Free Trade Agreement (FTA) tariff reductions.
