Ga3 gibberellic acid

When procuring Ga3, the purity level is the most critical factor; industrial grade usually requires 90% purity, while high-end agricultural applications demand 95% to 98% TC (Technical Concentrate). You must also specify the formulation type required for your market, such as 90% TC (powder), 40% SP (Soluble Powder), 20% ST (Soluble Tablet), or 4% EC (Emulsifiable Concentrate). Ensure the moisture content is below 0.5% to maintain chemical stability during long-term storage.

As a plant growth regulator, Ga3 must comply with FAO (Food and Agriculture Organization) specifications. Suppliers should provide a Certificate of Analysis (COA) for every batch and a Material Safety Data Sheet (MSDS). For entry into specific markets, check for EPA registration (USA), REACH compliance (EU), or local Pesticide Registration Certificates. If the product is intended for organic farming, verify OMRI listing or equivalent organic certifications.

Request a HPLC (High-Performance Liquid Chromatography) test report to verify the active ingredient content. For tablets or soluble powders, test the dissolution rate; high-quality Ga3 should dissolve completely in water without leaving sediment, which prevents clogging in irrigation sprayers. It is highly recommended to order a small sample (100g-500g) for greenhouse trials to observe its physiological effect on plant elongation and fruit setting before committing to bulk orders.

Ga3 is widely used for breaking seed dormancy, stimulating stem elongation, and increasing fruit size in crops like grapes, citrus, and cherries. However, because it is effective at extremely low concentrations (ppm - parts per million), buyers must ensure the supplier provides precise application manuals. Over-dosage can lead to spindly growth or reduced fruit quality, so sourcing from suppliers who offer technical support and dosage guidance is a significant value-add.

Ga3 is sensitive to light, heat, and moisture. Ensure the supplier uses fluorinated bottles or aluminum foil bags with vacuum sealing to prevent degradation. For bulk shipments, fiber drums with inner plastic linings are standard. Since it is a chemical product, verify the HS Code (typically 293220) and ensure the packaging meets UN-certified standards for hazardous or chemical goods to avoid customs seizures or fines.

Always use secure payment terms such as Letter of Credit (L/C) or Escrow services provided by reputable platforms like Made-in-China.com. Before payment, verify if the supplier has a Pesticide Production License and check their export history. Utilizing third-party inspection services (like SGS or Intertek) to perform a pre-shipment inspection (PSI) is the most effective way to guarantee that the chemical composition matches the agreed-upon specifications.

Focus on volume-based pricing tiers; prices for Ga3 TC can drop significantly when moving from 100kg to 1-ton metric volumes. Negotiate for customized packaging (OEM), such as specific tablet weights (e.g., 1g or 5g tablets) which can reduce your local repacking costs. Additionally, ask for price protection clauses or long-term supply contracts, as the raw material costs for gibberellins can fluctuate based on fermentation substrate prices.

Many countries have strict import quotas or specialized licenses for plant growth regulators. Check your local Ministry of Agriculture requirements for 'Import Permits.' Ensure all labels are translated into the local language and include the registration number, batch number, and expiration date, as missing information is a frequent cause of delays at international borders.
