Style-specific measurement	For solid cuts, report each required dimension and the in-size fraction; for minced material, report particle distribution; for moulded puree or portions, report unit mass and refining grade separately.	Apply the measurement method to the selected physical style; do not use a portion weight as a solid-cut dimension.

02 / Physicochemical & Residue Controls

Parameter	Specification / reference	Verification & order basis
Pesticide residue schedule	Named active ingredients and commodity-specific limits are selected for the destination market. EU source	Link farm spray history, laboratory LOQ and batch result to the destination MRL. EU database is one market reference; apply the actual destination rule.
Lead, cadmium and other contaminants	Apply the limit for the exact commodity and processed form in the destination market. EU source	State analyte, preparation basis, method, LOQ and lot result. Do not transfer a fresh-commodity limit to a processed form without the required assessment.

03 / Microbiological Criteria

Parameter	Specification / reference	Verification & order basis
Hygiene-indicator panel	Select aerobic count and relevant Enterobacteriaceae, coliform or E. coli indicators for the declared process and intended use. Codex	Report each quantitative result in CFU/g, method/reporting limit, sample plan and lot identity.
Pathogen acceptance programme	Define Salmonella and Listeria criteria when applicable to the destination, ready-to-eat status and buyer programme. Codex	State analytical portion, sample-unit plan, method and detected/not-detected reporting; identify the treatment and release basis.
Acceptance schedule	Select the test panel and limits by intended use (ready-to-eat or further processing), product form and destination. EU source	State organism, analytical method, sample mass and n/c plan; report actual lot results. A universal APC, coliform, Salmonella or Listeria limit is not assigned to every frozen product.

Shelf-life basis	The labelled period applies only to its validated pack and continuous stated storage condition. Codex	Review stability study or approved shelf-life file and production-date code.

06 / Process Controls

Parameter	Specification / reference	Verification & order basis
Processing Method	Sorting, peeling, washing, slicing / dicing / whole selection, IQF freezing, metal detection and packingPublished reference	Check the approved product flow, line settings and identified production record; validate numerical critical limits within the site HACCP plan.
Raw-material preparation checks	Confirm peeled state and wash/trim controls; separate pure water chestnut from a formulated mix.	Verify the selected product flow and the relevant trimming, sorting and pretreatment record.
CCP designation	Use the site-approved HACCP plan to identify true CCPs and their validated critical limits. Codex	Check hazard analysis, monitoring, deviation and corrective-action records. A quality-control step is not automatically a CCP.

07 / Ingredients, Additives & Allergens

Parameter	Specification / reference	Verification & order basis
Added glaze / coating declaration	Declare any intentionally added water glaze, syrup, oil or coating and the measurement basis; loose ice is assessed separately.	Verify formula/addition records; agree a deglazing or coating test and net-content basis where applicable.

Hazardous foreign matter	No foreign matter detected in the defined inspection sample; reject and investigate any finding.External reference Codex	Define visual-inspection sample size and detector challenge in the signed quality schedule. "None detected" is a sampling statement, not an absolute guarantee of zero particles.

09 / Packaging Materials & Label

Parameter	Specification / reference	Verification & order basis
Food-contact pack	Specify inner-contact material and obtain the applicable food-contact compliance declaration. NHC standard	Review film structure, supplier DoC, migration evidence and actual intended conditions. GB 4806 series is China-specific; EU export also checks Regulations 1935/2004 and 10/2011.
Carton and seal integrity	Define carton stacking strength, bag seal and puncture resistance for the confirmed net weight and pallet plan. EU source	Inspect pack drawing, compression/seal test and shipment configuration.
Label verification	Match product name, ingredient/allergen statement, net weight, lot/date, shelf life and storage instruction to the destination artwork. Codex	Approve artwork against the signed specification and destination rules.

10 / Detection & Traceability

Parameter	Specification / reference	Verification & order basis
Foreign-body detector	Validate Fe, non-Fe and stainless-steel challenge pieces for the actual product, aperture, pack and line; record the proven sensitivity. Codex	Challenge at defined start, changeover, interval and end points; retain rejection records. Do not copy generic detector sizes into a plant capability claim.
Lot traceability	Link input source lot, processing run, packaging code, test records, frozen storage and shipment to one finished lot. Codex	Trace one sample lot forward and backward in a recorded mock recall. Recall speed is stated only when the site has a validated target and record.

Order approval: Confirm the selected form and grade, ingredient formula, intended use, destination market, packing, sampling plan and test panel. The signed specification controls acceptance; the identified lot COA reports actual results.
