Human review

Compliance notes

  • No CAS number is expected for this type of seaweed-based fertilizer blend, but buyers should request CAS or inventory status for any separately added chelates, preservatives, surfactants, or micronutrient salts.
  • Request guaranteed analysis for calcium, total nitrogen, potassium, organic matter, alginic acid, amino acids, iodine, and all declared micronutrients.
  • Confirm heavy metal limits including arsenic, cadmium, lead, mercury, chromium, and nickel against the destination market fertilizer standard.
  • Request microbiological, pathogen, and phytosanitary-related documentation where required for seaweed-derived agricultural inputs.
  • Verify whether ISO9001 or other ISO certificates apply to the manufacturing site and product category, not only the trading entity.
  • Confirm SDS, TDS, COA, label draft, certificate of origin, packing list, commercial invoice, and customs HS classification support before order placement.
  • Check whether the product is non-DG for sea freight and air freight with supporting transport statement; classification may depend on final formula and additives.
  • Organic or bio-input claims should be validated against the buyer’s destination-market certification scheme before marketing or registration.
