For any rice pot destined for the US or EU market, spec 304 (18/8) stainless steel for the cooking surface. 201 costs 15–25% less, but its low nickel content can fail manganese-migration limits when it touches acidic food — and one rejected customs batch wipes out every dollar you saved. At Tailong, we produce both grades, and this is the same advice we give every distributor before they lock a specification.
Every Stainless steel rice pot we ship for export is built on a 304 food-contact interior with mill certificates to match. Whether you are a supermarket buyer, a cookware brand, or a wholesale distributor comparing suppliers in China, the difference between these two grades is the single most expensive thing to get wrong.
1. 304 vs 201: Where the Real Difference Shows Up
The core difference is nickel. 304 contains 18% chromium and 8–10% nickel, which forms a stable, corrosion-resistant surface that will not react with vinegar-based broths, tomato dishes, or salt-heavy rice recipes. 201 replaces most of that nickel with manganese: it looks identical to the eye, machines the same way, and costs less — but it corrodes faster and carries a real migration risk in lab tests with acidic food simulants.
| Property | 304 (18/8) | 201 |
| Nickel content | 8–10% | 1–4% (manganese substitute) |
| Corrosion resistance | High, stable passive layer | Noticeably lower, pits with salt/acid |
| Acidic-food migration risk | Passes EU/LFGB limits with margin | Can exceed Mn limits in testing |
| Cost vs 304 | Baseline | 15–25% cheaper |
| Best use | All cooking surfaces, export markets | Dry/cold display, non-acidic, budget lines |
There are legitimate uses for 201. Cold display of dry or packaged food minimizes metal migration, and for price-driven domestic-market lines it remains common. The problem is fraud, not the alloy itself: the most common quality scam in cookware manufacturing is 201 sold as 304, and the same pattern shows up across whole catalogs — stock pots, saucepans, even a Stainless steel snow flat pan ordered on a 304 quote arriving as 201. That is why the grade must be written into the purchase contract, not assumed from a product photo.
✅ Bottom line: 304 for any cooking surface sold into regulated export markets; 201 only for cold, dry, non-acidic applications where price rules.
2. How Do You Verify You're Getting Real 304?
Trust documents and instruments, not appearance. The two grades are visually indistinguishable, so verification has to happen at the material level. A professional manufacturer will expect these requests — if a supplier resists them, that tells you something too.
- Mill Test Certificate (MTC 3.1) — issued by the steel mill and traceable to a specific coil. Genuine 304 shows Cr ≥ 18.0% and Ni ≥ 8.0%. Nickel below 6% is almost certainly 201.
- On-site XRF test — a handheld analyzer reads the exact alloy composition in seconds. This is the gold standard for incoming inspection.
- Molybdenum drop test — a chemical spot check where reagent color reveals nickel content. Dark means low nickel; useful for quick factory-floor screening.
- Third-party inspection — engage SGS, Bureau Veritas, or TÜV to pull random samples from the production batch before shipment.
- Contract protection — add a material-substitution penalty clause and require the steel coil invoice to match the MTC heat number.
At Yongkang Tailong Kitchenware Co., Ltd., every export order — rice pots, steamers, or a Stainless steel wok — ships with mill certificates and supports customer-arranged XRF or third-party inspection before loading. The same XRF check works on any item in your container, so build it into your standard QC routine regardless of product type.
✅ Bottom line: Require an MTC 3.1, run XRF on samples, and put a substitution penalty clause in the contract — documents plus instruments are the only reliable proof.
FAQ
Q: Is 201 stainless steel illegal for cookware? A: No — it is a legal material. The issue is application. 201 can fail manganese-migration limits under EU food-contact testing with acidic simulants, so it should never be used for the cooking surface of rice pots, saucepans, or any vessel simmering acidic food. For cold, dry contact it performs acceptably.
Q: Can a magnet test tell 304 from 201? A: Not reliably. Both grades are largely non-magnetic in austenitic form, and cold working can make either grade slightly magnetic. A magnet tells you whether induction-ready 430 steel is present on the base — not what the cooking surface is. Use XRF or a mill certificate instead.
Q: Does Tailong offer OEM and ODM orders in 304 stainless steel? A: Yes. Tailong provides OEM/ODM custom production with 304 food-contact interiors as standard, including logo engraving, retail packaging, and factory-direct wholesale pricing. Samples can be arranged before bulk production so you can verify the grade yourself.
