Plant powder extract

Buyers must prioritize the Standardization of Active Ingredients (e.g., Ginsenosides, Curcuminoids) verified via HPLC (High-Performance Liquid Chromatography) or UV-VIS. Ensure the Extraction Ratio (e.g., 10:1 or 20:1) is clearly defined. Additionally, check the Mesh Size (typically 80-100 mesh for optimal solubility) and Moisture Content, which should ideally be below 5% to prevent microbial growth and clumping.

For food and supplement grades, the supplier must possess ISO 22000 or HACCP certifications. If exporting to the US, FDA Registration and GMP (Good Manufacturing Practice) compliance are non-negotiable. For European markets, ensure the product meets REACH and EU Novel Food regulations. Furthermore, request Third-Party Lab Reports for heavy metals (Lead, Arsenic, Mercury, Cadmium) and Pesticide Residue limits to ensure they fall within USP or EP standards.

Request a Certificate of Analysis (COA) that specifies the Solvent Used (Water, Ethanol, or Grain Alcohol). For beverage applications, 100% Water Solubility with no sediment is required. For cosmetics or capsules, stability under different pH levels and temperatures should be confirmed. Always request a Pre-shipment Sample (PSS) from the actual production batch to conduct in-house stability testing.

Plant extracts are primarily categorized into Nutraceuticals (immune support, energy), Cosmeceuticals (anti-oxidation, skin whitening), and Food Additives (natural colorants, preservatives). Understanding the End-Use allows the supplier to recommend the correct Carrier/Excipient (like Maltodextrin or Rice Flour) used to stabilize the powder.

Adulteration is a significant risk in the extract industry. Use Voucher Specimen Identification and request HPTLC (High-Performance Thin-Layer Chromatography) fingerprinting to ensure the extract is derived from the genuine botanical source. Avoid suppliers whose prices are significantly lower than the market average, as this often indicates the addition of synthetic analogs to boost test results.

Focus on Tiered Pricing based on active ingredient purity rather than just volume. Negotiate for Batch Consistency Guarantees, ensuring that the COA of the bulk order matches the approved sample. For high-value extracts, utilize Made-in-China.com's Secured Trading services to ensure payment is only released upon verification of shipping documents and quality compliance.

Plant powders are often Hygroscopic (absorb moisture). Ensure the packaging consists of Double-layer PE bags inside and Fiber drums outside, with Vacuum Sealing for sensitive extracts. For long-haul sea freight, specify Temperature-Controlled Containers if the extract is heat-sensitive, and always include Desiccant Packs to maintain dryness during transit.

Verify the HS Code (typically under Chapter 13 or 29) to determine import duties. Be aware of CITES (Convention on International Trade in Endangered Species); if the plant source is protected, you will need specific export permits. Ensure all labels include the Latin Name of the Botanical, the Plant Part Used, and the Country of Origin to avoid customs seizures.
