| Final goal | Connecting North American Producers/Exporters–Importers–Processors/Distributors–Foodservice/PB Buyers to Traceability and Repurchase |
The USDA ARS describes Northern wild rice as an aquatic grass native to North America , explaining that it is cultivated in artificially created flooded fields in Minnesota, USA, and harvested in natural bodies of water such as lakes and rivers in Manitoba, Canada. Therefore, MarketHub must list Wild Harvest and Cultivated Paddy as separate Source Types. ( ARS )
A study listed in FAO AGRIS also explains that Zizania palustris is an aquatic grass that grows naturally in lakes and gentle streams in North America and has been used as a edible grain. ( Agris )

Northern wild rice is an aquatic annual grass that grows in both natural lakes and streams as well as in flooded cultivation areas. Therefore, instead of using the standard rice cultivation dataset as is, fields for water bodies, water levels, and natural harvesting/cultivation types must be added. ( ARS )
The USDA's 2025 study reported the first occurrence of disease caused by Bipolaris zeicola in Northern wild rice and explains that pathogen identification is important because various Bipolaris species can produce similar symptoms. Disease data is managed not merely at the level of 'leaf blight,' but, whenever possible, down to the pathogen level. ( ARS )

Korean production
Domestic wild rice cultivation area: To be entered after verification of official raw data
Domestic wild rice production volume: To be entered after verification of official raw data
In this v1.0 version, national statistics on nationwide production volume and cultivation area for edible seeds of Zizania palustris could not be verified in South Korea. Therefore, domestic online sales and import distribution cases are not substituted for Korean production statistics.
From the current perspective of MarketHub operations, it is appropriate to evaluate the economic feasibility of the domestic aquatic cultivation pilot separately while prioritizing the verification of the import-procurement-buyer market, rather than assuming it is a large-scale domestic production crop .

Trade Management
Wild rice is botanically different from ordinary rice, and for customs clearance, the detailed item description in the actual current HSK must be checked. In this v1.0, the Korea Customs Service has not been able to officially confirm the current standalone tariff code for wild rice, so an HS Code is not arbitrarily assigned.
item | Operating Principles |
| HS | Input later after official verification of the current HSK by the Korea Customs Service |
| Item Description | Check for Wild rice / Zizania spp. |
| Regular rice | Oryza sativa and statistical separation |
| Natural harvesting and cultivation type | Retain Source Metadata after customs clearance |
| For seeds | Separate quarantine and item classification from edible grains |
| Powder/Mixed Grain | Separate HS review by processing status |
| instant food | Finished goods HS code separate |
| Import volume | Subsequent verification of official raw data by the Korea Customs Service |
| Revenue | Further verification |
| Major suppliers | Enter after checking the detailed HS code |
| Quarantine | Quarantine verification by raw grain and seed status |
| FTA | Check Country of Origin, Tariff Code, and Rules of Origin |
| Customs clearance unit price | Compare only the same HS, product condition, and unit |
Domestic wild rice import volume, import value, major supplier countries, and customs clearance unit price: To be entered later after verification of official raw data from the Korea Customs Service.
The total import volume of ordinary rice or 'other grains' is not arbitrarily converted to the import volume of wild rice.

The USDA verifies that Northern wild rice is produced not only in natural waters but also in created flooded rice paddies. Therefore, if a supply contract accepts only simple wild rice without verifying the production method, Source Intelligence is lost. ( ARS )
In addition, as the USDA releases reports on new pathogens in Northern wild rice in 2025, disease management is not automatically mapped to disease names of common rice. ( ARS )
