Direct supply from origin farms and our audited extraction facilities. High bulk density, verified micro-milling, and complete lot traceability designed for high-standard formulations.
From the booming craft beverage scenes in Montrose and The Heights to functional beverage bottling throughout the Greater Houston Metropolitan Area, supply chain resilience is decisive.
Specialty coffee establishments and Japanese-inspired tea lounges across Houston’s Midtown, Montrose, and Memorial neighborhoods are moving away from bitter, culinary-grade dust masquerading as ceremonial tea. Houstonians expect electric jade hues, natural umami richness without added sweeteners, and complete solubility when frothed with oat or almond milk.
Texas has become one of the fastest-growing regions for functional beverage co-packing. Houston brands formulate ready-to-drink (RTD) cans combining ceremonial matcha with nootropics like NMN, NAD+, and functional lion's mane. These industrial liquid lines require ultra-fine particle suspensions (800–1200 mesh) that resist precipitation and oxidation inside transparent bottles.
Sourcing directly from our integrated processing factories gives Houston importers, roasters, and distributors an enormous cost advantage. With deep-water container access at Port Houston (Barbours Cut and Bayport terminals) alongside air cargo clearance at George Bush Intercontinental Airport (IAH), buyers avoid West Coast bottlenecks and intermediate distributor markups.
A Certificate of Analysis is more than a formality—it is your legal shield against FDA rejections, adulteration, and brand reputational damage. Compare your current supplier’s paperwork against our benchmark protocol.
| Analytical Marker | Standard Industry Baseline (Often Problematic) | Our Certified Factory Release Protocol |
|---|---|---|
| Amino Acid & L-Theanine Content | 1.0% – 1.8% (Culinary/late autumn harvests; produces an astringent, excessively bitter brew). | ≥ 2.5% to 3.8% L-Theanine (HPLC Verified) from 25–30 day shaded spring flush; yields sweet vegetal umami. |
| Chlorophyll & Color Coordinates | Dull, yellow-green olive tint (Hunter L*a*b* values show elevated b* positive yellowness). | Deep vibrant jade (Chlorophyll ≥ 6.5 mg/g), protected from thermal oxidation via chilled micro-milling. |
| Pesticide Multi-Residue Screening | Self-declared internal declarations or spot tests omitting newly regulated triazole compounds. | BS EN 15662 Multi-Residue Panel by SGS, testing over 500+ compounds against stringent USDA NOP & EU MRLs. |
| Granulometry & Mesh Sizing | 300–400 mesh; leaves sandy sediment at bottom of cups and clogs commercial nitro dispensers. | 1000–1200 mesh (D90 < 15 microns) via stone and air-jet pulverizers, allowing complete colloidal emulsion. |
| Heavy Metals (Pb, As, Cd, Hg) | Broad "conforms" statement without quantitative ICP-MS numbers; poses heavy California Prop 65 risk. | Strict ICP-MS quantitation: Pb < 0.5 ppm, As < 0.3 ppm, Cd < 0.1 ppm, Hg < 0.05 ppm on every released drum. |
| Microbiological & Water Activity | Moisture > 6.5%, aw > 0.40; accelerates degradation and mold formation during humid Gulf Coast transit. | Moisture ≤ 4.5%, aw < 0.28; vacuum hermetic nitrogen-flushed barrier bags preventing clumping. |
Combining traditional agro-botanical cultivation with state-of-the-art cGMP pharmaceutical extraction and milling systems.
Tea bushes are covered with black mesh shade tarps for 21 to 28 days prior to harvesting, blocking 90% of sunlight. This triggers intense chlorophyll synthesis and supercharges the biosynthesis of L-Theanine while suppressing bitter catechin development.
Hand-selected first-flush spring tender shoots are instantly steamed within hours of picking to arrest enzymatic oxidation. Leaves are rapidly dried, stripped of stems and veins in multi-stage winnowers, and processed into pristine Tencha leaf flakes.
Using slow-turning natural granite stones and temperature-controlled air-jet micro-pulverizers, Tencha flakes are ground into 1000–1200 mesh powder at temperatures under 38°C. This preserves the sensitive polyphenol matrix and vital aromatic terpenes.
Because green tea powder degrades rapidly when exposed to humidity and oxygen, every batch undergoes immediate nitrogen-flushed vacuum sealing inside multi-layer aluminum barrier packaging with food-grade food desiccant canisters before export loading.

Direct answers addressing freight routes, FDA clearance protocols, storage against Texas heat, and OEM customization.
For standard air freight (FedEx/DHL/air cargo arriving at George Bush Intercontinental Airport - IAH), transit takes 5 to 8 business days door-to-door. For full container loads (FCL) or palletized less-than-container loads (LCL), ocean shipments route directly to Port Houston (Bayport or Barbours Cut terminals) with typical sailing windows ranging between 24 and 32 days from Qingdao/Shanghai ports. We handle full DDP (Delivered Duty Paid) terms, handling all customs clearance and drayage right to your Houston warehouse.
Houston’s notorious ambient heat and relative humidity represent a serious risk to matcha’s volatile color and delicate aroma compounds. Our ceremonial grade matcha powders are dried to under 4.5% moisture content and hermetically sealed inside thick, light-impervious aluminum composite bags with food-safe desiccant bags and nitrogen gas flushing. For large ocean container shipments during the Texas summer, we offer refrigerated reefer containers or specialized thermal insulated container liners to protect against cargo hold overheating.
Every commercial consignment exported to the United States includes complete documentation: a batch-matched Certificate of Analysis (COA) specifying assay, heavy metal ICP-MS, and microbiology; Material Safety Data Sheet (MSDS); USDA Organic NOP Transaction Certificate (if organic); Certificate of Origin; and commercial invoice with exact tariff codes (HTS 0902.20). Furthermore, Xi'an Vexli Bio-Tech is fully registered with the U.S. FDA, and our logistics team files FDA Prior Notice confirmations before aircraft take-off or vessel dispatch.
