Importing and Distributing Agricultural Pesticides in Peru: What Buyers Should Know About Class 9 Solid Products

Introduction

Peru is an important agricultural market with strong demand for crop-protection products used in crops such as rice, maize, potato, coffee, grapes, citrus, avocado, vegetables and other commercial crops.

For international suppliers, however, selling pesticides into Peru is not simply a matter of offering the right active ingredient and price. Agricultural pesticides must comply with SENASA registration requirements, import procedures, local labeling rules and, where applicable, dangerous-goods transport regulations.

This is particularly relevant for solid formulations such as:

Thiamethoxam 25% WG
Imidacloprid 70% WG
Copper Oxychloride + Metalaxyl 50% WP
Metalaxyl + Mancozeb 58% WP
Copper Hydroxide 77% WP

These products are all solid formulations, but that does not automatically mean they are all transported under the same dangerous-goods classification.

The correct approach is:

Product Registration + SDS Verification + Transport Classification + Packaging Compliance + Import Documentation

Peru Requires Agricultural Pesticide Registration

In Peru, agricultural pesticide regulation is managed by SENASA — Servicio Nacional de Sanidad Agraria.

SENASA states that agricultural pesticides imported, manufactured, formulated, packaged, distributed or commercialized in Peru must be registered with the authority.

Peru's pesticide regulatory system operates under the national agricultural pesticide framework together with the Andean Community system, including Decision 804 and the Andean Technical Manual for registration and control of agricultural chemical pesticides.

This means a distributor cannot assume that a formulation legally sold in another country can automatically be imported and commercialized in Peru.

Before shipment, the buyer should confirm:

Active ingredient registration status
Exact concentration
Formulation type
Registered crop uses
Target pests or diseases
Label requirements
Import authorization
Technical dossier requirements

Importers Must Also Be Registered

Peru regulates not only the pesticide product but also the companies involved in its import and distribution.

SENASA's regulatory framework requires registration of relevant participants, including importers, exporters, distributors, manufacturers and formulators.

SENASA also provides an online pesticide procedure system for processes such as:

Import authorization
Efficacy trial applications
Import inspection procedures
Agricultural pesticide administrative processes

For overseas manufacturers, this means the Peruvian buyer should normally confirm its SENASA status before an order is finalized.

What Happens When Pesticides Arrive in Peru?

SENASA states that imported agricultural pesticides may require:

Product registration
Importer registration
Physical inspection in the primary customs zone
Import inspection and authorization documentation before entry

For exporters, this makes document consistency especially important.

The following information should match across the commercial documents:

Product name
Active ingredients
Concentration
Formulation
Batch number
Net weight
Manufacturer
Country of origin
Label information
SDS information

Differences between the invoice, packing list, COA, SDS and registered specification can create problems during clearance.

Are All Solid Pesticides Class 9 Dangerous Goods?

No.

This is one of the most important points for Peruvian importers and exporters.

Products such as WG, WDG and WP are physically solid, but physical state alone does not determine the dangerous-goods class.

A solid pesticide may be:

Class 6.1 toxic substance
Class 9 environmentally hazardous substance
Another regulated dangerous-good category
Not regulated as dangerous goods for transport

The decision depends on the finished formulation, not just the active ingredient name.

Therefore:

WG or WP ≠ automatically Class 9

and

solid pesticide ≠ automatically UN3077

Why UN3077 Is Common for Solid Pesticides

Many pesticide formulations are hazardous to aquatic organisms but do not meet the criteria for a more specific transport hazard class.

When the finished product meets the relevant environmental-hazard criteria, a common international transport classification is:

UN 3077 — Environmentally Hazardous Substance, Solid, N.O.S.

Class: 9
Packing Group: III

This is commonly seen with solid pesticide products that pose significant aquatic environmental hazards.

However, exporters should never assign UN3077 merely because the product contains an insecticide or fungicide.

The correct classification should come from the product-specific SDS Section 14 — Transport Information.

Product Examples Relevant to Peru

1. Thiamethoxam 25% WG

Thiamethoxam 25% WG is a systemic neonicotinoid insecticide used in registered crop-protection programs against susceptible sucking pests.

As a WG formulation, it is physically a solid granule.

Because thiamethoxam can be hazardous to aquatic organisms and pollinators, some commercial formulations may carry dangerous-goods transport classifications. However, the exact UN number and transport class must be confirmed from the manufacturer's current SDS.

For a Peruvian buyer, important checks include:

SENASA registration
Exact formulation specification
Approved crops and pests
SDS Section 14
Packaging and label compatibility

2. Imidacloprid 70% WG

Imidacloprid 70% WG is another high-concentration neonicotinoid insecticide formulation.

It is commonly supplied as a solid water-dispersible granule.

Depending on the formulation's environmental classification, some products may be transported as environmentally hazardous solids under Class 9.

But different formulations can contain different carriers, dispersants and concentrations, so the transport classification must not be copied from another manufacturer's SDS.

For Peru, the exporter should provide the exact SDS corresponding to the batch and commercial formulation being supplied.

3. Copper Oxychloride + Metalaxyl 50% WP

This type of product combines:

A copper-based contact fungicide
A systemic phenylamide fungicide

The WP formulation is a solid wettable powder.

Copper compounds can be highly hazardous to aquatic organisms, which may influence transport classification. Metalaxyl also contributes its own toxicological and environmental profile.

For this reason, the combined formulation may qualify for Class 9 in some commercial products, but classification must be based on the finished formulation's data.

Peruvian importers should confirm:

Exact ratio + SDS + registration + crop/disease claims

before placing an order.

4. Metalaxyl + Mancozeb 58% WP

Metalaxyl + Mancozeb 58% WP is a well-known systemic plus contact fungicide combination.

It is often positioned for oomycete disease management, including registered late blight and downy mildew programs.

As a WP product, it is solid.

Because mancozeb-containing formulations can carry environmental hazard classifications, some products may be shipped as dangerous goods.

However, again, the correct classification must come from the actual commercial SDS rather than an assumed generic category.

This is particularly important for shipments to Peru because the transport description on:

Bill of lading
Dangerous goods declaration
Packing list
SDS

must be consistent.

5. Copper Hydroxide 77% WP

Copper Hydroxide 77% WP is a high-concentration copper fungicide/bactericide formulation.

Copper compounds can be highly toxic to aquatic life. Therefore, some copper hydroxide formulations may meet criteria for environmentally hazardous solid classification.

This makes UN3077 Class 9 a possible transport classification for certain formulations.

But the supplier still needs to verify:

Product-specific SDS
Marine pollutant status
Packing group
UN number
Proper shipping name

before shipping.

Why the SDS Is Critical

For agricultural pesticide exports to Peru, the SDS is not merely a marketing document.

Section 14 — Transport Information should be checked carefully.

Typical information includes:

UN Number
Example: UN3077

UN Proper Shipping Name
Example: Environmentally Hazardous Substance, Solid, N.O.S.

Transport Hazard Class
Example: Class 9

Packing Group
Example: III

Marine Pollutant / Environmentally Hazardous Status

The SDS should match the actual formulation being exported.

A supplier should not use an SDS for:

Imidacloprid 70% WG

to classify:

Imidacloprid 20% SL

because concentration, physical state and formulation components are different.

Packaging for Dangerous Goods Shipments

If the product is classified as dangerous goods, export packaging must comply with the applicable transport requirements.

Depending on shipment mode and classification, this may involve:

UN-approved packaging
Correct hazard labels
UN number markings
Proper shipping name
Net quantity information
Orientation or handling marks where required
Marine pollutant marks where applicable

The freight forwarder should receive the SDS before booking so that dangerous-goods acceptance can be confirmed with the shipping line.

For Peruvian destinations, many agricultural imports enter through Callao, making correct maritime documentation especially important.

Peru-Specific Compliance Matters Beyond Shipping

Dangerous-goods transport classification and pesticide registration are two separate compliance systems.

A product can be correctly shipped as:

UN3077 Class 9

and still be illegal to commercialize in Peru if it is not registered with SENASA.

Likewise, a pesticide may be registered in Peru but still require special dangerous-goods shipping procedures.

Therefore, professional buyers should check both:

Transport Compliance

and

Agricultural Pesticide Registration

before placing an order.

Peru Has Banned Certain Active Ingredients

Peruvian importers should also verify whether the active ingredient remains legally permitted.

SENASA has previously prohibited the registration, importation and commercialization of certain agricultural pesticides.

For example, Peru prohibited agricultural products containing paraquat and later prohibited chlorpyrifos, with the chlorpyrifos prohibition extending to use, commercialization, storage, distribution and packaging from August 2024.

Other active ingredients such as phorate and dicofol have also been prohibited.

This shows why checking current SENASA status before shipping is essential.

A product being commercially available elsewhere does not prove it can legally enter Peru.

What Documents Should a Peruvian Buyer Request?

Before confirming a pesticide order, a professional importer should normally request and review:

Certificate of Analysis — COA
Safety Data Sheet — SDS
Technical Data Sheet — TDS
Product specification
Commercial invoice
Packing list
Certificate of origin where required
Registration-support documents
Product label artwork
Batch information
Dangerous-goods declaration where applicable

SENASA specifically monitors pesticide registration, importation, storage, commercialization and product labeling as part of the national agricultural pesticide control system.

Recommended Procurement Workflow for Peru

A safer purchasing process is:

1. Confirm active ingredient legality in Peru

Check whether the ingredient is permitted and whether restrictions apply.

2. Confirm SENASA product registration

Verify the exact active ingredient, concentration and formulation.

3. Review the SDS

Pay particular attention to Section 14.

4. Confirm transport classification

Determine whether the product is non-dangerous, Class 9, Class 6.1 or another class.

5. Confirm packaging

Verify UN packaging requirements if dangerous goods regulations apply.

6. Confirm documents

Ensure COA, SDS, invoice, packing list and labels all use consistent product information.

7. Confirm freight booking

Send the SDS to the freight forwarder before shipment.

Common Mistakes Importers Should Avoid

One common mistake is assuming that every WP or WG pesticide is automatically UN3077 Class 9.

Another is copying dangerous-goods information from a similar product.

For example:

Thiamethoxam 25% WG from Supplier A

and

Thiamethoxam 25% WG from Supplier B

may not necessarily have identical transport classifications if their formulations and hazard data differ.

A third mistake is confirming freight before checking whether the product has the necessary registration in Peru.

The better approach is to verify regulatory and transport requirements before production and shipment.

FAQs

Are all WP and WG pesticides Class 9 dangerous goods in Peru?

No. WP and WG only describe formulation type. Dangerous-goods classification depends on the finished product's hazard profile and SDS.

What does UN3077 mean?

UN3077 is used internationally for certain environmentally hazardous solid substances, N.O.S., generally transported as Class 9 when they meet the relevant classification criteria.

Can a pesticide be imported into Peru just because it has an SDS?

No. Agricultural pesticides also need to comply with Peru's SENASA registration and import requirements.

Who regulates agricultural pesticides in Peru?

The principal agricultural pesticide authority is SENASA, under Peru's Ministry of Agrarian Development and Irrigation.

Should importers classify a product from the active ingredient alone?

No. Transport classification should be based on the complete commercial formulation and its current SDS.

What should exporters check before shipping to Callao?

Confirm SENASA compliance, product registration, import authorization, SDS Section 14, dangerous-goods classification, packaging, labels and shipping documents.
