Quick answer
The markets you sell into and the country where the plant is built decide which compliance rules apply, so write those markets into the specification before you ask for quotes. An export plant typically has to show three things. First, a HACCP-based food-safety system — US rules (21 CFR Part 123) require it of seafood processors, including foreign processors whose products are imported. Second, hygiene design that meets the destination's rules — for the EU, Regulation (EC) No 853/2004, Annex III, Section VIII for fishery products. Third, eligibility to export — for the EU, the establishment itself must appear on the EU list, which is proposed by the exporting country's competent authority. Machinery installed in the EU must also meet EU machinery law, which from 20 January 2027 generally means Regulation (EU) 2023/1230 instead of the old Directive. Refrigeration, especially ammonia systems, falls under its own safety rules.
Key points
- Start from the destination markets. They decide the hygiene, labelling and approval requirements the equipment has to support.
- For EU exports, the plant itself must be listed as an authorised establishment for the product category. Country eligibility alone is not enough.
- Under the Codex standard for quick frozen shrimps or prawns (CXS 92-1981), the declared net contents of glazed product exclude the glaze. Design glazing and checkweighing around that rule.
- Machinery for EU sites placed on the market from 20 January 2027 is generally assessed under Regulation (EU) 2023/1230. Ask each supplier which regime its declaration of conformity will cite.
- In the US, ammonia refrigeration systems holding 10,000 lb or more of ammonia are covered by OSHA's Process Safety Management standard. Other countries have their own thresholds.
Start with a market-and-product matrix
Before comparing processing lines, list each product (for example, raw peeled frozen shrimp, cooked shrimp, fresh fillets) and each destination market. The combination decides the rules the plant and its records must satisfy. Suppliers can then quote equipment that supports those rules instead of a generic line.
| Destination | Plant-level requirement | Evidence to plan for |
|---|---|---|
| European Union | The establishment must be on the EU list of authorised non-EU establishments for the product category. Listing is proposed by the exporting country's competent authority and held in TRACES-NT. Hygiene rules: Regulation (EC) No 852/2004 (general) and 853/2004, Annex III, Section VIII (fishery products). | Competent-authority inspection reports, HACCP plan, temperature and cleaning records, water and ice quality records |
| United States | Seafood HACCP under 21 CFR Part 123, which also applies to foreign processors whose products are imported; food-facility registration with FDA. | Hazard analysis and written HACCP plan, sanitation monitoring records, corrective-action records; FDA's Fish and Fishery Products Hazards and Controls Guidance (June 2022 edition) as the reference |
| Other markets | National food-safety law of the importing country. The Codex Code of Practice for Fish and Fishery Products (CXC 52-2003) is the international reference many authorities build on. | Confirm national requirements with the importer and the importing authority before design freeze |
Hygiene design questions to put in the RFQ
Equipment does not make a plant compliant, but poor layout and hard-to-clean machines can make compliance impossible. Ask designers and equipment suppliers to answer these points in writing, so offers can be compared on the same basis.
- Product flow: one-way movement from raw receiving to finished packing, with physical separation of raw and cooked or ready-to-eat areas.
- Food-contact materials: material specifications and declarations for every surface that touches product, packaging or ice.
- Cleanability: cleaning and disinfection instructions for each machine, access for cleaning, drainage, and whether parts must be dismantled to clean them.
- Water and ice: source, treatment and monitoring for process water and ice, sized for peak demand.
- Temperature control: chilling capacity at receiving, room temperatures by zone, and freezing performance at your product size and peak throughput.
- Waste and by-products: separate routes for shells, heads and trimmings so they never cross clean product flows.
- Staff hygiene: changing rooms, hand-wash and boot-wash points located on the routes staff actually walk.
Frozen shrimp: glaze, net weight and labelling
Glazing protects frozen shrimp from dehydration, but it also affects how much product the buyer actually receives. The Codex Standard for Quick Frozen Shrimps or Prawns (CXS 92-1981) states that where the food has been glazed, the declared net contents shall exclude the glaze. Commercial buyers usually specify a maximum glaze and a test method in their purchase specification.
For the plant, this means glazing must be controlled and repeatable. Checkweighers and quality-control procedures must work on net weight, and the deglazing test method should be agreed with customers before production starts. Our wholesale shrimp RFQ checklist covers the buyer-side specification.
Machinery conformity: the 2027 switch in the EU
Regulation (EU) 2023/1230 on machinery was adopted on 14 June 2023 and published on 29 June 2023. It generally applies from 20 January 2027 and repeals Directive 2006/42/EC from that date; a few provisions apply earlier. For a processing line ordered in 2026 for installation in the EU, the delivery date can therefore decide which regime the conformity documents must follow.
Lines are often assembled from machines made by several manufacturers. Decide in the contract who is responsible for the conformity of the integrated line, the risk assessment of the interfaces between machines, and the final documentation. For plants outside the EU, ask which national machinery and electrical safety rules apply at the site, and require documents for those rules, not only for the supplier's home market.
- State in the RFQ which legal regime the EU declaration of conformity must reference, based on the planned delivery date.
- Require technical documentation, instructions and safety information for each machine and for the integrated line.
- Name the party responsible for integrating the line and its conformity.
- Include factory acceptance and site acceptance tests that check safety functions, not only throughput.
Refrigeration and freezing: safety and resilience
Freezers, chillers and cold stores are usually the plant's largest energy users and its largest single-point-of-failure risk. Many industrial freezing and cold-storage systems use ammonia, which brings specific safety duties. In the US, OSHA's Process Safety Management standard covers ammonia refrigeration systems containing 10,000 lb or more of ammonia. Other countries set their own thresholds and duties, so confirm them with a local engineer.
Cold-chain temperatures are a regulatory requirement, not just a quality target. For example, EU rules require frozen fishery products to be kept at no more than −18 °C in all parts of the product (Regulation (EC) No 853/2004, Annex III, Section VIII). Size freezing and storage for your peak intake and product size, and ask how the system behaves when one compressor or evaporator is out of service.
- Refrigerant choice and total charge, with the safety regime that charge triggers at your site.
- Machinery-room design, gas detection, alarms and emergency procedures.
- Freezing-time validation at your product size and load, not the catalogue maximum.
- Redundancy (N+1) for compressors and critical pumps, and the backup power strategy.
- Operator training, maintenance contract and spare-parts stock.
Comparing processing-line offers on the same basis
Offers for processing equipment are hard to compare because they quietly differ in scope and assumptions. Convert each offer into the same table and mark every figure as a supplier claim, your own estimate, or a verified fact (for example, from a witnessed test or a reference site you visited).
| Item | What to ask for | How to label it |
|---|---|---|
| Scope boundary | Which machines, conveyors, utilities, controls, installation and civil works are included or excluded | Contractual scope |
| Throughput basis | Raw input kg/h versus finished output kg/h, for each product and size grade | Supplier claim until tested |
| Yield | Assumed yield per product and raw-material condition | Supplier claim; verify on trial or reference data |
| Utilities | Installed and running power (kW), water (m³/h), refrigeration load (kW), compressed air | Supplier claim; check against your site capacity |
| Hygiene and conformity documents | Food-contact declarations, cleaning instructions, declaration of conformity and the legal regime it cites | Document received / missing |
| Testing and handover | Factory acceptance test, site acceptance test, commissioning, training | Contractual milestone |
| Spares and service | Recommended spares list, local service capability, response times, warranty terms | Contractual commitment |

Buyer questions
What approvals does a shrimp processing plant need to export to the EU?
The country must be eligible for the product, and the plant itself must appear on the EU list of authorised establishments for that category. The listing is proposed by the exporting country's competent authority and published through TRACES-NT. Consignments also need the required official certificates. Confirm the current requirements with the competent authority before investing.
Does HACCP apply to equipment suppliers?
HACCP is the processor's obligation. Equipment suppliers should provide what the processor needs to apply it: cleanable design, food-contact material declarations, cleaning instructions and verified performance at critical steps such as cooking and freezing.
Is the glaze included in the net weight of frozen shrimp?
Under the Codex standard CXS 92-1981, the declared net contents of glazed product exclude the glaze. Your customers' specifications and the importing country's labelling law decide the exact requirement, so agree the glaze limit and test method in writing.
When does the new EU Machinery Regulation apply?
Regulation (EU) 2023/1230 generally applies from 20 January 2027, when it replaces Directive 2006/42/EC. A few provisions apply earlier. For deliveries around that date, fix the applicable regime in the contract.
Can FishMatch Group give a price for a processing plant?
We do not publish prices without dated, scope-specific evidence. The main cost drivers are capacity, product mix, level of automation, freezing and cold-storage capacity, utilities and civil works. Our example shrimp processing project shows how scope is structured. For commercial projects (generally USD 250,000 and above), we run supplier-neutral, human-reviewed RFQs so offers can be compared on the same basis.
