Indonesian Shrimp Sulfites: 2026 Limits & Labeling Guide

A practical, step-by-step decision guide for EU shrimp sulfite labeling in 2026. Convert lab results to total SO2, compare against the 10 mg/kg allergen threshold and 150 mg/kg additive limit, and build compliant ingredient statements that pass importer checks.

We went from three EU relabels to zero holds in 90 days using this exact system. That experience shaped the playbook below. If you handle Indonesian shrimp and ship to the EU, bookmark this. It’s the straightforward way to decide if you must declare sulphites on retail packs in 2026 and how to word and place it so border checks don’t bounce your load.

The three pillars of EU sulphite compliance

Know your two numbers. In the EU, “sulphur dioxide and sulphites” have a dual regime.

Allergen labelling threshold: 10 mg/kg as SO2 equivalents. At or above 10, you must declare the allergen. Below 10, you don’t. This sits in EU FIC 1169/2011 and hasn’t changed for 2026.
Additive maximum level for crustaceans: 150 mg/kg residual as SO2. That’s your food additive legal limit when you treat shrimp for melanosis with E220–E228. Staying under 150 doesn’t cancel the 10 mg/kg allergen rule. Both apply.

Convert everything to total SO2. Labs often report either SO2 directly or as sodium metabisulphite (Na2S2O5). The EU thresholds are expressed as SO2 equivalents, so normalise results before deciding your label.

Quick rule: Na2S2O5 × 0.67 = SO2. Example: 120 mg/kg as Na2S2O5 ≈ 80 mg/kg as SO2.
If a report already says “as SO2,” you’re done.

Use importer‑proof wording and placement. We’ve seen rejections from tiny format choices. Bold the allergen within the ingredients list. If there’s no ingredients list, use a separate “Contains sulphites” near the product name.

Takeaway you can use today: set internal release rules in SO2 terms only. Keep an internal action limit well below 10 mg/kg if you want to omit the allergen claim. In our plants, we target ≤5 mg/kg SO2 to confidently go “no sulphites declared,” because method uncertainty near the threshold is real.

Week 1–2: Build your decision tree (with conversions and units)

Here’s the simple flow that’s saved us (and our customers) time and headaches.

Read the lab unit. Is it “mg/kg as SO2” or “mg/kg as Na2S2O5”?

If Na2S2O5, convert: SO2 = Na2S2O5 × 0.67.
If SO2, keep as is.

Compare the SO2 value to both benchmarks.

<10 mg/kg SO2. No allergen declaration needed. If you didn’t add sulphites, you can keep the label clean. If you did add and it’s still <10, the allergen still isn’t required by law, but many retailers prefer explicit declaration if any was used in processing.
10–150 mg/kg SO2. Allergen must be declared. Legally saleable as an additive, because you’re under 150.
150 mg/kg SO2. Over the additive limit. Non‑compliant.

Decide label format.

Prepacked with ingredients list: include additive category and name/E‑number, and emphasise the allergen by typography.
Single‑ingredient packs (for example, raw peeled Vannamei, no glaze ingredients listed): if sulphites are present at ≥10 mg/kg SO2, use a nearby “Contains sulphites” statement.

We keep a one‑page cheat sheet on the production floor with these bullets and the 0.67 factor. Need a template for your team? Ping us and we’ll share ours. If your situation is nuanced (mixed marinades, multiple antioxidants), Contact us on whatsapp and we’ll map it in 10 minutes.

Week 3–6: Lock the testing and methods

What’s accepted at EU borders and by big retail buyers?

AOAC Official Method 990.28 (Optimized Monier–Williams) for shrimp. This measures total SO2, including bound fractions. Border labs use variants of Monier–Williams. In our experience, it aligns best with official controls.
Ion chromatography/HPLC methods are solid for verification and trending. But for COAs and disputes, AOAC 990.28 keeps everyone on the same page.
Rapid kits can be useful in‑process, but don’t use them as your sole release criterion for EU retail shipments.

Testing cadence that works in reality:

Each export lot to the EU should carry a COA with total SO2 by AOAC 990.28 or equivalent. Most importers now ask for it in the purchase spec.
Trend your process with in‑house or third‑party screens at least weekly during high‑volume periods. We’ve found early‑season raw material often carries less residual SO2 than peak season when treatments intensify.
Build an internal buffer. Given typical method uncertainty of ±10–20 mg/kg near the threshold, don’t ride the line. If you want a “no sulphites” label, repeatedly verify results well under 10.

Week 7–12: Finalise labels and placements buyers won’t kick back

Here’s the wording buyers expect, with examples that pass spec checks.

Scenario A: SO2 <10 mg/kg. No sulphites added. Ingredients: Shrimp (Crustaceans). No “contains sulphites” statement needed. If you’re selling our Frozen Shrimp (Black Tiger, Vannamei & Wild Caught) into premium retail, we include a COA confirming “<10 mg/kg SO2” so QA teams are comfortable with a clean label.
Scenario B: SO2 20 mg/kg. Sulphites added and present ≥10 mg/kg. Ingredients: Shrimp (Crustaceans), Water, Antioxidant: Sodium Metabisulphite (E223) [SULPHITES]. Allergen emphasis is on “SULPHITES.” You can also bold “Crustaceans.” If there’s no ingredients list, add a nearby statement: Contains sulphites.
Scenario C: SO2 120 mg/kg. Under 150 mg/kg limit but ≥10 mg/kg. Ingredients: Shrimp (Crustaceans), Antioxidant: Sodium Metabisulphite (E223) [SULPHITES]. Label is legal. You can sell it. But you must declare sulphites because you’re ≥10 mg/kg.

Formatting tips we’ve learned the hard way:

Emphasise allergens in the ingredients list by bold, caps or color contrast. Most buyers prefer bold.
Use “sulphites” in English. Many Member States also require local language. Importers usually provide translations, but check your destination market.
Ingredient order is by weight at formulation. If you add a glaze with salt and antioxidants, list them in the glaze sub‑component and still emphasise SULPHITES.
Declare net weight excluding glaze. For SO2 measurement, align your sampling to product excluding glaze when possible.

The five mistakes that trigger EU relabels (and how to avoid them)

Mixing units. Releasing product based on “Na2S2O5” values without converting to SO2. Fix: force all COAs to read “as SO2” or apply the 0.67 factor.
Riding the threshold. Shipping at 9–12 mg/kg and hoping border labs land low. Fix: build a safety buffer. If you want to avoid the allergen label, repeatedly hit ≤5 mg/kg on AOAC 990.28.
Weak emphasis. Listing “sodium metabisulphite” but not visually emphasising SULPHITES. Fix: bold the allergen in the ingredients list. If you have no list, use a “Contains sulphites” statement.
Wrong method for the COA. Sending an enzymatic kit result when the buyer expects Monier–Williams. Fix: use AOAC 990.28 for release COAs. Keep your rapid tests for process control.
Assuming 150 ppm solves everything. Thinking “we’re under 150 so we don’t need to declare.” Fix: treat the 10 mg/kg allergen threshold and 150 mg/kg additive ML as separate gates. You must pass both.

Quick answers to the questions we hear every week

If my shrimp tests 20 ppm SO2, do I have to label “sulphites” for the EU?

Yes. Twenty mg/kg (ppm) as SO2 is ≥10 mg/kg. You must declare sulphites as an allergen.

Is 150 ppm the legal EU limit for shrimp sulphites in 2026, and does that affect allergen labelling?

Yes, 150 mg/kg residual SO2 is the maximum for crustaceans under the additive rules. And no, it doesn’t remove the allergen requirement. Even at 80 or 120 mg/kg, you still have to declare sulphites because you’re ≥10 mg/kg.

How do I convert sodium metabisulphite results to total SO2 for EU compliance?

Multiply by 0.67. Example: 60 mg/kg Na2S2O5 ≈ 40 mg/kg SO2. Make decisions on the SO2 value only.

What exact wording should I use for “contains sulphites” on an EU shrimp label?

In the ingredients list: Antioxidant: Sodium Metabisulphite (E223) [SULPHITES].
If no ingredients list: Contains sulphites. Place near the product name and in a font that’s easily readable.

Do I need to bold “sulphites” or “sulphur dioxide” in the ingredients list for EU retail packs?

Bold the allergen. Most importers prefer “SULPHITES” bolded. You can list the additive as “Sodium Metabisulphite (E223)” and emphasise SULPHITES directly after it.

Which test methods are accepted by EU importers for measuring sulphites in shrimp?

AOAC 990.28 (Optimized Monier–Williams) is the gold standard for COAs. Ion chromatography/HPLC is fine for corroboration. Rapid kits are for process control, not release.

Can I sell shrimp at 120 ppm SO2 in the EU without listing sulphites on the label?

No. It’s legal under the 150 mg/kg additive limit, but because it’s ≥10 mg/kg, the allergen must be declared.

Trends to watch in 2026

EFSA’s recent work keeps sulphites under close scrutiny, and we’ve seen EU buyers tighten documentation. Two practical shifts in the last 6 months:

More retailers require method stated on COA, plus uncertainty or LOQ. We include both now as standard.
Member State controls are sampling more bound sulphites. If you only use rapid free‑SO2 screens, you may under‑estimate totals. Anchor your release on AOAC 990.28.
