Table salt

When sourcing table salt, you must ensure the supplier complies with ISO 22000 or HACCP (Hazard Analysis and Critical Control Points) for food safety management. For specific markets, look for FDA registration (USA), EFSA compliance (EU), or Halal/Kosher certifications if targeting niche consumer segments. The salt should meet the Codex Alimentarius (CXS 150-1985) standard for food-grade salt, ensuring a Sodium Chloride (NaCl) content of at least 97% on a dry matter basis.

Table salt is categorized by grain size: Fine Grain (standard table use), Coarse/Crystal (grinders), and Flake. You must specify the requirement for anti-caking agents (like Sodium Ferrocyanide/E535), which prevent clumping during sea transit. Additionally, if your target market mandates Iodization, ensure the supplier can precisely calibrate the Potassium Iodate levels (typically 20-40 mg/kg) to meet local public health regulations.

Salt is highly hygroscopic (absorbs moisture), which can lead to hardening. For bulk B2B orders, insist on moisture-proof PE/PP woven bags with an inner liner. For retail-ready packaging, multi-layer laminated pouches or BPA-free plastic shakers are preferred. Ensure the packaging includes UV protection if stored in outdoor transit hubs to prevent degradation of the packaging material itself.

Request a Certificate of Analysis (COA) for every batch. Key parameters to check include heavy metal limits (Lead < 2mg/kg, Arsenic < 0.5mg/kg, Mercury < 0.1mg/kg) and insoluble matter content (should be < 0.2%). For sea salt, ask for microplastic filtration reports to meet modern consumer demands for purity.

The biggest risks are moisture damage and regulatory rejection. Salt can easily cake if exposed to high humidity during sea freight. Always use container desiccants and ensure the supplier provides a Health Certificate and Certificate of Origin to avoid customs delays. On Made-in-China.com, prioritize Audited Suppliers to mitigate the risk of receiving industrial-grade salt labeled as food-grade.

Salt is a low-margin, high-volume commodity. Negotiate based on Total Landed Cost. While the unit price per ton might be low, ocean freight can represent 50% of your cost. Aim for Full Container Load (FCL) orders to optimize shipping costs. Ask for tiered pricing where a 5% discount is applied for every additional 5 containers per quarter.

Use Escrow services or Letters of Credit (L/C) for large volumes. Before the final payment, hire a third-party inspector (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI). They should verify the net weight, NaCl purity, and packaging integrity at the manufacturer's warehouse or the loading port.

Due to its weight and low value-to-weight ratio, Sea Freight (FCL) is the only economically viable method for table salt. For inland countries, a Multimodal (Sea-Rail) approach is best. Ensure the supplier uses 20ft containers rather than 40ft, as salt is dense and will hit the weight limit of a 20ft container long before the volume limit of a 40ft container is reached.
