FDA’s refusal lists have included Taiwanese pomelo green tea and lemon black tea — same reason each time: pesticide residues. These were fully compliant products in Taiwan. The problem is not sloppy quality control; it is a fact many exporters learn only after a refusal: the US runs a different residue table. Tea and coffee are categories where Taiwan has real export strength — and among the categories where we most often see “compliant product refused at the door.” Here is the full anatomy.
Two tables: passing Taiwan does not mean passing the US
US pesticide regulation runs on a tolerance list: each pesticide-crop combination must have an established tolerance to be legal, and a combination not on the list means zero tolerance — any detectable amount is a violation, however small. Taiwan’s MRL table and the US tolerance list are set independently; a pesticide with a tea tolerance in Taiwan but none in the US is not rare. Hence the brutal outcome:
- Taiwanese lab reports: all passing
- The same lot in the US: tests positive for a chemical with no US tolerance on tea — violation, refusal
The correct pre-shipment move is not to take comfort in the Taiwanese report but to walk your spray program against the US tolerance list item by item. Missing combinations must be fixed in the field — that is a growing-season change, not a paperwork change.
Sampling and Import Alerts: one violation, long-term cost
Tea and coffee sit in a high-sampling band for residues. The mechanism to respect is FDA’s Import Alert: once your product or factory is red-listed for residue violations, subsequent shipments can be detained without physical examination (DWPE) — the burden of proof reverses, and you must submit passing evidence shipment after shipment and petition formally for removal before normal clearance resumes. In practice that process runs in months, with third-party testing at your cost on every lot, and the alert attaches to the manufacturer and product — switching US importers does not shake it. The price of one lucky shipment is every later shipment becoming slower and more expensive.
“Organic”: the Taiwanese mark does not transfer
The US market pays a premium for organic tea and coffee, but printing organic or the USDA Organic seal on US packaging requires certification recognized by the US — Taiwan’s organic mark cannot be used directly. Claiming organic without certification is misbranding, and it bites exactly like a residue violation. Growers and roasters aiming at the organic position should put certification at the very front of the export plan: conversion periods mean it cannot be patched three months before shipping.
How SKYCARGO takes it from there
SKYCARGO INC holds FDA and USDA agent status and can act as your Importer of Record and consignee. On tea and coffee projects we ask three things before booking: has the spray program been walked against the US tolerance list; is there a US-panel residue report; will the product claim organic. Then we file Prior Notice and book the freight; on arrival, the same team faces FDA sampling, any hold, and release, then warehousing and distribution. For a high-sampling category, having someone watching the examination queue — and acting the moment a hold lands — is a very different experience from finding help after the fact. Personal tea and coffee consolidation belongs with Shiptw.
