Nori seaweed

Nori is typically graded by color, texture, and luster. Gold Grade is the highest quality, characterized by a deep dark green or blackish hue, a glossy sheen, and a crisp texture that melts in the mouth. Silver and Blue grades are more cost-effective for mass-market snacks or lower-end sushi catering. Buyers should check for uniform thickness and the absence of holes or 'dead spots' in the sheets.

As a processed seafood product, Nori must comply with strict international food safety standards. Ensure the supplier holds HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 certifications. For entry into the US market, FDA Registration is mandatory, while the EU market requires compliance with heavy metal limits (especially Arsenic and Cadmium) and organic certifications if marketed as such.

To maintain crispness and prevent mold, the moisture content must be kept below 5%. Professional B2B packaging should include aluminum foil bags with deoxidizers or silica gel desiccant packets. For sushi grade Nori, the standard sheet size is 19cm x 21cm, and you should specify the weight per 100 sheets (typically 230g to 280g) to ensure density and quality.

Nori is categorized by its application: Yaki Nori (Roasted) is the standard for sushi and onigiri; Ajitsuke Nori (Seasoned) is flavored with soy sauce or chili for snacking; and Kizami Nori (Shredded) is used as a garnish for ramen or donburi. Buyers should select the processing type based on whether they are supplying industrial food manufacturers, restaurant chains, or retail supermarkets.

The biggest risk is moisture absorption during sea transit, which ruins the texture. Always stipulate hermetic sealing and consider temperature-controlled containers if shipping through tropical zones. Another risk is pesticide or heavy metal residue; always request a COA (Certificate of Analysis) from a third-party lab like SGS for every batch before shipment.

Focus on harvest seasons (typically winter); booking volume during the harvest can secure lower prices. Negotiate based on annual volume commitments rather than one-off orders to reduce the unit price by 10-15%. Ask for OEM packaging customization (private labeling) to be included in the bulk price to increase your brand value.

Use Secured Trading Services provided by Made-in-China.com to ensure payment is only released upon proof of shipment. For first-time orders, utilize a 30% deposit and 70% balance against the Bill of Lading (B/L). Conduct a factory audit or use a third-party inspection service to verify the supplier's drying and roasting facilities.

Nori is fragile and light, so it is prone to crushing. Ensure the outer cartons are double-walled corrugated fiberboard with a high crush test rating. Since Nori has a high 'volume-to-weight' ratio, calculate your shipping costs based on volumetric weight to avoid unexpected logistics expenses. Ensure the HS Code (typically 2008.99 or 1212.21) is correctly declared to avoid customs delays.
