# Bulk Soy Sauce and Seasoning Sauce Sourcing from China: Grades and Specs

Sauces are the quiet workhorses of food manufacturing. A single tank of soy sauce can flavour thousands of litres of finished product, so a specification that drifts is felt across an entire production run. Sourcing bulk sauce is about locking down measurable parameters.

Key specifications to fix
-------------------------

- **Total nitrogen:** the primary proxy for protein content and sauce quality in soy sauce grading.
- **Salt (NaCl):** drives taste and acts as a natural preservative.
- **Total solids / brix:** influences body and mouthfeel.
- **pH and acidity:** affects stability and flavour balance.
- **Colour and microbiology:** consistent appearance and safe counts.

Naturally brewed vs blended
---------------------------

Naturally fermented sauce commands a premium and a deeper flavour; blended or hydrolysed sauces hit a cost point and consistency that some industrial buyers prefer. Know which one your recipe assumes, because swapping silently changes taste and label claims.

**Practical tip:** buy a retained sample with each lot and keep a sensory panel trained on your reference sauce.

Packaging and handling
----------------------

Sauces ship in drums, IBCs or flexitanks depending on volume. Salt and acid make them relatively robust, but light and heat still degrade colour. Store cool and dark, and confirm shelf life under your own warehouse conditions rather than the supplier’s ideal one.

MOQ and lead time
-----------------

Bulk sauces reward scale, so MOQs are usually high. Plan a first order sized to validate taste and process, then negotiate volume pricing once the spec is frozen and repeatable.
