Standards That Apply to Exported Tea

Shipping tea abroad means meeting requirements that domestic distribution does not impose.

Pesticide residue limits vary by country

Tea is an agricultural product, so residues from cultivation are subject to limits.

Each country sets its own values, and a level permitted in Japan can exceed the threshold in a destination market. Regions with strict standards, such as the EU, also regulate a longer list of compounds.

Some tea gardens are managed specifically for export, selecting or avoiding treatments according to destination requirements.

Matcha faces tighter conditions

For brewed tea, testing sometimes applies to the infusion rather than the leaf. Residues that do not transfer into hot water do not reach the consumer.

Matcha is different. You consume the whole ground leaf, so limits apply to the leaf itself.

Securing export-compliant raw material is therefore the first constraint.

Facility requirements

Japan requires HACCP-based hygiene management for food businesses generally, fully enforced from June 2021.

Destination markets may require additional certification or registration.

Labeling

Language, allergen declarations, nutrition information — all governed by destination rules.

Japanese labels cannot simply be applied and shipped.

Sweetened products add requirements

Added sugar changes the nutrition declaration. Certain sweeteners trigger additional obligations.

Aspartame requires a phenylalanine statement in Japan, and comparable requirements are typical elsewhere.

It compounds the supply constraint

Producers and facilities able to meet these conditions are limited.

Tencha already faces constraints — plants take years to establish, shading is labor-intensive, stone mills produce roughly 40 g per hour. Export compliance narrows the field further.

That is part of why supply does not expand quickly when demand does.
