FDA Detention Sampling & Testing Services
Sampling and Testing Coordination
FDA Detention Sampling helps importers, manufacturers, customs brokers, warehouses, and regulatory professionals coordinate product sampling, chain of custody, independent laboratory testing, shipping, and documentation for shipments detained by FDA.
Service Overview
FDA detention sampling services cover the practical work between an FDA detention notice and a usable laboratory report: reviewing the available detention information, coordinating access to the shipment, arranging representative sample collection, documenting sample identity and chain of custody, packaging and transporting samples, coordinating independent laboratory analysis, and organizing the reports and supporting records for the authorized parties handling the response.
The exact scope of any case depends on:
Common Situations
Sampling and laboratory coordination is most often requested in situations like these:
Not every FDA detention requires private testing. The need for sampling or testing should be determined based on the detention notice, applicable procedures, professional advice, and case-specific facts.
Full Service Scope
Every case is assembled from the services below based on the product, the detention reason, and the shipment's circumstances. Nothing is applied as a template.
Each case starts with a review of the available shipment and detention information to understand the practical sampling and testing needs. This is a logistical review, not legal advice or an FDA decision.
Documents reviewed may include
Detained cargo is often held at a facility that must authorize any sampling. We coordinate with warehouses, cold-storage facilities, bonded facilities, container freight stations, distribution centers, and third-party logistics providers, alongside the importer, broker, and freight forwarder.
Access depends on
A laboratory result is only as good as the sample behind it. We help plan collection so samples fairly represent the detained lot — there is no universal sampling plan, and the right approach varies case by case.
Planning considers
Qualified or appropriate sampling resources may be coordinated when available for the shipment's location and product. Samplers are engaged for the case rather than employed in every market.
Coordination depends on
Chain-of-custody records connect the tested sample to the detained shipment without gaps, documenting identity, handling, and every transfer along the way.
Records may document
Packaging is planned around the product, the laboratory method, and the transport conditions — requirements vary and are confirmed per case.
Considerations may include
Once collected and packaged, samples move to the laboratory under coordinated logistics. Courier timing is coordinated but not guaranteed, since carriers control their own networks.
Coordination may cover
Testing is coordinated with an appropriate independent laboratory matched to the case — never a government facility, and never presented as one.
Laboratory matching considers
Microbiological analysis is frequently requested for food, seafood, spices, and supplements detained for contamination concerns. Available methods depend on the product and the laboratory.
Examples may include
Chemical analysis addresses detentions involving residues, additives, and contaminants across food, supplement, cosmetic, and drug categories.
Examples may include
When FDA questions what a product actually is or contains, identity and composition analysis may support the response.
Examples may include
Physical parameters can matter as much as contamination results, particularly for perishable, canned, and packaged products.
Examples may include
Products, manufacturers, or shipments connected with FDA import alerts or detention without physical examination (DWPE) may require coordinated sampling and testing. Import alert matters often require a broader regulatory strategy — testing alone may not be sufficient.
Review import alert testing supportPhotographic documentation can support the record when facility permissions and case requirements allow it.
Documentation may include
Available laboratory reports and supporting records are organized for the importer, broker, regulatory consultant, attorney, or other authorized party handling the response. Documents are not automatically submitted to FDA — use and submission remain decisions for the authorized parties.
A detention case can involve ten parties working from different information. We keep the logistics and information moving among the importer, manufacturer, broker, warehouse, freight forwarder, sampler, courier, laboratory, and the consultants or attorneys involved — coordinating logistics and information, not acting as legal counsel or a government representative.
Every one of the services above is scoped to the individual case. Before work begins, the proposed coordination scope is reviewed with you so expectations, third-party involvement, and limitations are clear from the start.

Transparency
We would rather be clear now than surprise you later. Sampling and testing coordination is logistics and documentation work — it does not control regulatory decisions, third-party conduct, or laboratory outcomes.
Depending on the case, separate services may also be required from attorneys, customs brokers, regulatory consultants, laboratories, warehouses, couriers, samplers, freight providers, process authorities, or other specialists. Those services are provided by those parties, on their own terms.
Getting Started
Five steps take a case from first contact to a confirmed coordination scope.
The notice identifies the detention reason, the entry, and the response window — it anchors everything that follows.
Entry documents, product details, labels, and quantities let the practical needs be assessed accurately.
The facility holding the cargo and its contact determine how access and sampling can be coordinated.
Known testing requirements, laboratory instructions, or professional recommendations shape the plan.
You receive the proposed scope — what is included, what depends on third parties, and what is not covered — before work begins.
Prepare Your Submission
Send what you have — missing items can be gathered while coordination begins. A complete submission simply moves faster.
A sampling coordinator can review your documents, confirm what is feasible for your shipment, and outline the next steps.
Review your case with a sampling coordinatorCost Transparency
Sampling and testing cases usually involve independent third parties — facilities, samplers, laboratories, and couriers — each with their own charges. These are separate from coordination services and are billed by, or passed through from, the parties that perform the work.
Whenever possible, the scope and applicable third-party charges are reviewed with you before work begins, so costs are understood rather than discovered.
The Value of Organization
A detention response can fall apart on small failures: a sample pulled from the wrong lot, an undocumented transfer, a laboratory that never received handling instructions, or a warehouse waiting on paperwork nobody sent. Organized coordination exists to prevent exactly those failures.
Who We Work With
Different parties come to a detention with different responsibilities. Coordination serves each of them without acting as anyone's legal representative.
The party responsible for the entry, usually driving the response and the decision to test.
Producers whose product or facility is named on the notice or an import alert.
Brokers managing the entry who need sampling logistics handled without losing the timeline.
Facilities holding detained cargo that need clear, formal sampling instructions.
Forwarders tracking cargo status and coordinating movement around the detention.
Foreign Supplier Verification Program importers supporting verification with analysis.
Consultants building the response who need reliable sampling and testing execution.
Counsel handling the regulatory matter who need documented, traceable evidence.
Distributors with inventory committed to customers waiting on the detained entry.
E-commerce sellers whose imported inventory is detained before reaching fulfillment.
Brands protecting product claims, quality, and launch timelines during a detention.
Retailers with purchase orders and shelf dates tied to the detained shipment.
Coverage
Coordination may be available at ports, warehouses, cold-storage facilities, bonded facilities, container freight stations, distribution centers, importer locations, and third-party logistics facilities.
Detained cargo most often sits in and around the major trade markets:
Availability depends on shipment access, location, facility authorization, product type, sampler availability, and case-specific requirements.
Common Questions
Direct answers to what importers and trade professionals ask most about the service scope.
No. Some detentions are resolved through documentation, labeling corrections, or other responses without any laboratory testing. Whether sampling is appropriate depends on the detention reason stated on the FDA notice and, often, professional advice from a broker, consultant, or attorney.
When the detention involves contamination, identity, or composition questions, laboratory evidence is more likely to be relevant — but the decision should always be based on your specific notice and case facts.
No. FDA determines its own requirements and makes the final admissibility decision. What we do is coordinate the testing identified for the case — based on the detention reason, applicable methods, laboratory capabilities, and the instructions of the authorized parties handling the response.
Where the required analysis is unclear, a regulatory consultant or attorney is the right party to determine strategy; we coordinate execution once the direction is set.
Often yes, subject to the facility's authorization and the rules that apply to goods held under bond. Bonded facilities have their own procedures for access, supervision, and documentation, which vary by facility.
The warehouse name and contact are among the first intake details reviewed, because they determine what is feasible for your specific shipment.
The facility holding the cargo controls physical access, and the importer or its broker typically authorizes activity related to the entry. No private company can compel access to a detained shipment.
Our role is coordinating among the importer, broker, and facility so that authorization, timing, and instructions line up before a sampler arrives.
Not necessarily. Qualified or appropriate sampling resources are coordinated for each case based on the shipment location, the product, facility rules, required qualifications, and availability.
What matters for your case is that the collection is performed appropriately and documented — collector information is part of the chain-of-custody record.
Yes, temperature-controlled packaging and transport may be coordinated when the product and testing method require it — including refrigerated and frozen samples with appropriate containment.
Feasibility depends on the courier's capabilities, the laboratory's receiving hours, and the distance involved, which is why temperature condition is requested at intake.
Laboratory reports and supporting records are organized and provided to you and your authorized parties — the importer, broker, consultant, or attorney handling the response. Documents are not automatically submitted to FDA.
How and whether results are submitted is a decision for the authorized parties managing the regulatory response, and the appropriate submission path depends on the case.
Laboratory, courier, sampler, and warehouse charges are third-party costs, separate from coordination services. Each third party bills for its own work at its own rates.
Whenever possible, the applicable third-party charges are identified and reviewed with you before work begins, so the total picture is understood up front.
No. No private company can guarantee FDA release, and you should be cautious of anyone who does. FDA makes the final admissibility decision based on its own review.
What testing coordination provides is documented, traceable laboratory evidence that the authorized parties may use in the response. Whether that evidence is sufficient depends on the detention reason, the results, and FDA's evaluation.
Coordination may be available at authorized locations throughout the United States, with the heaviest activity around major import markets. Availability for any specific shipment depends on its location, facility authorization, the product, and sampler availability.
Provide the shipment location at intake and feasibility can be confirmed quickly. See the service areas page for the markets covered.
If the current facility cannot or will not authorize sampling, the options are worked through with your broker and the facility — which may include additional authorization paperwork, supervised access, or in some cases coordinating an authorized transfer of the goods, subject to the applicable procedures for detained cargo.
Warehouse access is never guaranteed, which is why the facility's position is confirmed early in the case rather than assumed.
Yes, sampling and laboratory logistics may be coordinated for products, manufacturers, or shipments associated with FDA import alerts, including detention without physical examination (DWPE) situations, depending on the alert and the case requirements.
Import alert matters often require a broader regulatory strategy beyond testing alone. Review the import alert testing support page for how these cases differ.
