Dried Tangerine Peel

Processing standard (GBA Traditional Chinese Medicine Standard DWQZB20240001, Chenpi (Guang Chenpi)):

Guang Chenpi Shreds: remove impurities, spray with water, soak/moisten, cut into shreds, dry
Characteristics: irregular strips/shreds; outer surface orange-red to reddish-brown with fine wrinkles and depressed dotted oil glands; inner surface pale yellowish-white, rough, with yellowish-white/yellowish-brown vascular bundles; aromatic, slightly pungent and slightly bitter
Content: same as the crude drug — hesperidin and narirutin (per Pharmacopoeia: hesperidin ≥ 2.0% for Guang Chenpi)

Grade classification (based on the same grading as whole peel, cut to form within the grade):

Spec (harvest stage)	Grade	Key requirements
Da Hong Pi (large red peel)	1st / 2nd / Standard	Large, supple sheets, fresh aroma, free from impurities, insect damage, mould
Wei Hong Pi (semi-red / 2nd red)	Same	Large, supple, slightly sweet-bitter
Qing Pi (green peel)	Same	Harder, pungent aroma, pungent-bitter

Packing features of shred/slice forms: shreds and slices are more uniform and compact than whole peel, with higher density and smaller footprint — the main export form. However, their larger surface area makes them more prone to moisture absorption and oil bleeding, so moisture-proof packing is essential.

Bulk / export packing:

Bags: 25 kg / 50 kg PP woven or plain unprinted bags (inner liner for products prone to mould, insects or oil bleeding)
Cartons: inner bag + reinforced moisture-proof corrugated carton, common sizes 1 kg (30×25×20cm) / 1.5 kg (36×26×20cm) / 2.5 kg (38×30×25cm) / 5 kg (45×35×30cm)

Container loading (estimated): shreds/slices are markedly denser than whole peel, so a 20ft container should load more than whole peel (≈ 2.5–4 t). Shreds/slices: approx. 4–6 t per 20ft and 8–12 t per 40ft (estimates; subject to compression and packing method).

Storage & transport: clean, dry, covered transport; protect from moisture, mould, oil bleeding and insects; avoid direct sunlight and rain; never mix with toxic, odoriferous or contaminated goods.
