Before importing tea, ask the exporter for the harvest (flush) date, moisture content, and any food-safety or pesticide-residue test results — tea quality and shelf life depend heavily on these three factors, not just the grade name.
Grade and origin get most of the attention in tea sourcing conversations, but three quieter factors do more to determine whether a shipment actually performs well once it reaches your market — and they're the questions a first-time buyer is least likely to think to ask.
Harvest (flush) date. Tea, unlike many agricultural products, is often marketed by "flush" — the specific harvest period, particularly relevant for Darjeeling, where first flush (spring) and second flush (early summer) produce noticeably different flavor profiles even from the same estate. Beyond flavor, harvest date also tells you how fresh the tea actually is relative to when you're buying it — tea does degrade in flavor and aroma over time, even when stored well, so a lot has aged sitting in a warehouse tells you something important about what you're actually getting versus what a grade name alone would suggest. Always ask for the harvest date, not just the grade and origin.
Moisture content. This is a specific, testable number, and it matters more than most buyers realize. Tea with moisture content that's too high is prone to mold growth and flavor degradation during shipping and storage, particularly on longer sea-freight routes through humid conditions. Reputable exporters test and can state moisture content on request — typically tea should sit in a fairly tight, low percentage range depending on the processing type. A supplier who can't or won't provide this figure is a signal worth taking seriously, since it's a basic quality-control metric any serious tea operation tracks as a matter of course.
Food-safety and pesticide-residue testing. This has become an increasingly important gate for tea imports into several major markets, with maximum residue limits (MRLs) for various pesticides now enforced more strictly than in past years. A shipment that fails a destination country's residue testing on arrival isn't just a quality problem — it can mean the shipment gets rejected, held at customs, or destroyed, at real cost to the buyer. Ask for recent lab test results before committing to an order, particularly if you're importing into the EU, UK, or US, where enforcement tends to be strictest.
Additional questions worth asking, beyond the big three. What's the tea's country of processing versus country of growth (sometimes different, and worth knowing)? What packaging format will it ship in, and is that packaging appropriate for your climate and shipping route (more on this in our packaging article)? Does the exporter provide a certificate of analysis alongside the shipment, or only on request?
Why this level of diligence matters more for tea than it might for other products. Tea is a food product with a genuine shelf-life and safety dimension that leather or apparel simply don't have. A quality issue in a leather good is a customer-satisfaction problem; a quality or safety issue in tea can become a regulatory and health problem, with real consequences for a buyer's business if it isn't caught before the shipment leaves origin.
Our approach. We provide harvest date, moisture content, and available lab testing documentation as standard information on every tea quote, without requiring a buyer to specifically ask — because these aren't optional extras, they're the basic due diligence any serious tea buyer needs, and we'd rather volunteer it upfront than have a buyer wonder why it wasn't offered.
