1. What Mexican Buyers Should Do First
For a Mexican company importing mobile phone screens from China for the first time, the safest approach is to build a complete import plan before comparing unit prices. The final cost and customs risk normally depend on five factors: the product’s physical structure, its Mexican tariff classification, NOM requirements, the shipping arrangement, and the importer’s own customs qualifications.
As a Chinese wholesale exporter of mobile phone screens, ARI Electronics can support Mexican customers from product confirmation through export-document preparation. A typical purchasing process includes the following steps:
1.Confirm the screen model, quality grade, construction, and quantity.
2.Obtain specifications, photographs, bills of materials, and packing data.
3.Ask a Mexican customs broker to confirm the applicable TIGIE/NICO classification and tariff treatment.
4.Check NOM and other non-tariff requirements based on the final classification.
5.Select the Incoterm, transport method, insurance arrangement, and delivery location.
6.Estimate IGI, import VAT, customs-broker fees, port charges, and inland transportation.
7.Complete purchasing, export, transportation, customs clearance, and delivery to the Mexican warehouse.
Mexican buyers do not need to manage every information exchange alone. ARI Electronics can prepare product and export documentation so that the buyer can coordinate more efficiently with its Mexican customs broker, freight forwarder, and warehouse team.
2. What ARI Electronics Can Provide to Mexican Customers
Clear supplier information is essential for a smooth import. Before quotation and shipment, ARI Electronics can prepare the following information according to the order requirements:
| Support area | Typical information | Why it matters |
| Product identification | Brand, model, display technology, and quality grade | Supports purchasing and inventory control |
| Technical data | Specifications, dimensions, interfaces, BOM, and product photographs | Supports tariff classification and compliance review |
| Packing information | Individual packaging, carton quantity, gross weight, net weight, and carton dimensions | Supports freight quotation and packing-list preparation |
| Commercial documents | Commercial invoice, packing list, and purchase-order information | Supports export and import declarations |
| Order information | Quantity, unit price, lead time, and Incoterm | Supports quotation and landed-cost planning |
| Quality information | Sample approval, quality grade, and inspection requirements | Reduces disputes in volume orders |
| After-sales information | Warranty, replacement, and problem-reporting procedures | Supports the buyer’s after-sales management |
ARI Electronics should not describe every product simply as “mobile phone parts.” Standard LCD panels, OLED assemblies, touch-screen assemblies, components with driver boards, and complete phones should be identified separately whenever applicable. Clear model information and product descriptions help Mexican buyers maintain consistent customs and inventory records.
3. HS Codes: From the Chinese Export Code to Mexico’s TIGIE/NICO
3.1 The six-digit HS code is only the starting point
The international Harmonized System generally provides a six-digit classification level. Mexican import declarations require the applicable Mexican tariff classification under the TIGIE, together with the NICO, Mexico’s commercial identification number. SNICE explains that the NICO adds a fifth pair of digits to the eight-digit tariff item to further distinguish merchandise. Source1: SINCE:structure of Mexican's TIGIE and NICO
Therefore, an HS code provided for export from China should be treated as a reference for product communication and preliminary quotation only. The Mexican buyer must ask a local customs broker to confirm the complete Mexican classification, tariff rate, unit of measure, and regulatory requirements based on the actual product.
3.2 Why there is no universal code for every mobile phone screen
A mobile phone screen may be:
•An LCD or OLED panel without a touch layer;
•A display module with a touch layer, cover glass, and flex cable;
•A display assembly with a driver IC or interface board;
•A component with a control unit or other electronic parts; or
The product’s principal function, construction, ability to operate independently, power characteristics, and condition of sale may affect classification. Importers should not determine the final Mexican code solely from invoice descriptions such as “LCD screen,” “OLED screen,” or “mobile phone spare parts.”
3.3 The recommended classification process for Mexican buyers
Step 1: Request model-specific information from ARI Electronics. Obtain specifications, photographs, BOMs, dimensions, weight, interfaces, and packaging data.
Step 2: Submit the information to a Mexican customs broker. The broker should review the Mexican tariff text, section and chapter notes, and the product’s actual configuration.
Step 3: Confirm the current IGI rate. Do not estimate import duty using another country’s rate, an old supplier quotation, or an unverified online source.
Step 4: Check NOM and other non-tariff measures. After the tariff item is identified, verify whether it appears in the current NOM annex or another regulatory list. [2]
Step 5: Keep a classification file. The Mexican importer should retain technical documents, the broker’s written opinion, the final declaration description, and the tariff version used. If the model, construction, packaging, or included accessories change, the classification should be reviewed again.
ARI Electronics can support this process by providing accurate product information. However, neither a supplier’s export code nor a generic product name should be treated as a universal Mexican HS/TIGIE/NICO classification without local review.
4. NOM Compliance: Start with the Product’s Actual Form
4.1 NOM applicability depends on the tariff item and product scope
NOM refers to Mexico’s official standards system. Whether a particular NOM requirement applies generally depends on the Mexican tariff item, NICO, product description, technical characteristics, intended use, scope, and stated exceptions.
SNICE’s NOM annexes normally identify the tariff item, merchandise description, applicable NOM, and limiting conditions. [2] A product should not be assumed to require a specific certification merely because it is an electronic product. Conversely, a product should not automatically be treated as exempt merely because it is a repair part.
4.2 Key questions for different screen configurations
| Product configuration | Questions the Mexican importer should verify |
| Stand-alone display module without a power supply | Whether the tariff item appears in the current NOM annex and whether a parts exception applies |
| Display assembly with touch layer and flex cable | Whether the construction changes the tariff classification or regulatory scope |
| Component with a driver board or control unit | Whether it has additional electrical functionality that triggers other requirements |
| Product supplied with a battery, power module, or adapter | Electrical safety, labeling, instructions, and conformity-assessment requirements |
4.3 NOM-024, NOM-001, NOM-019, and NOM-212
NOM-024-SCFI relates to instructions, warranties, and labeling for certain electronic, electrical, and household products. SNICE materials show that NOM requirements are generally linked to specific tariff items and scopes rather than being applied uniformly to all electronic products. [2]
The relevance of NOM-001, NOM-019, NOM-212, or another standard must also be checked against the product’s actual function and the current regulatory list. A stand-alone replacement screen is not technically the same product as a complete phone with communications functions. Rules applicable to a finished device should not automatically be applied to a screen module.
ARI Electronics can provide specifications, photographs, packing information, model lists, and other product documents available for the order. The Mexican importer, its customs broker, and any applicable conformity-assessment body remain responsible for confirming the final NOM position, assessment method, labeling requirements, and import declaration responsibilities.
Before shipment, the Mexican buyer should obtain confirmation of:
1.The final TIGIE/NICO classification;
2.Whether the current NOM annex covers that tariff item;
3.The applicable NOM, assessment method, and responsible party;
4.Whether Spanish-language labels, instructions, or warranties are required;
5.The specific exception or limitation if the product is considered outside the requirement; and
6.Any other non-tariff measures, quotas, or trade-remedy measures.
A historical annex may support background research, but it should not replace the official version in effect on the shipment date.
5. The Complete Import Process for Mexican Customers
Step 1: Send the purchasing requirements to ARI Electronics
The Mexican buyer should provide the target brands and models, screen type, quality grade, estimated quantity, delivery city, required arrival date, and preferred Incoterm. If the order includes standard screens, OLED screens, frame assemblies, or other repair parts, each category should be quoted and documented separately.
Step 2: Approve samples and quality standards
Before placing a volume order, the buyer should verify display performance, touch function, cosmetic grade, compatibility, packaging, and labels. The approved sample and quality grade should be recorded in the purchase order so that both parties have the same acceptance standard for the shipment.
Step 3: Confirm the Mexican importer’s qualifications
A Mexican importer generally needs a valid RFC, an active electronic signature, and registration in the Padrón de Importadores. SAT lists conditions including an active RFC, valid e.firma, compliance with tax obligations, a located or validated tax address, and an authorized customs broker, customs attorney, or legal representative for foreign-trade operations. [2]
Step 4: Ask the broker to confirm HS, NOM, and taxes
The Mexican buyer should send ARI Electronics’ technical documents to its local customs broker and confirm the TIGIE/NICO, IGI, NOM, import VAT, and other non-tariff requirements before placing a large order or releasing the shipment.
Step 5: Select the Incoterm and transport method
The parties should clearly define FOB, CIF, DAP, or another Incoterm, and separate the product price, international freight, insurance, destination charges, Mexican inland transportation, and delivery location. Air freight may suit small or urgent replenishment orders. Ocean freight may suit larger volumes, but the decision should consider quantity, delivery time, and inventory cost.
Step 6: Prepare export and import documents
ARI Electronics should provide the commercial invoice, packing list, and other agreed export documents. The Mexican buyer and customs broker should verify the model, quantity, unit, unit price, country of origin, transport information, and packaging details.
Step 7: Clear customs and pay import charges
ANAM requires importers to maintain inventory controls, retain origin and provenance evidence, provide customs-value information to the customs broker, transmit commercial and value information, submit the pedimento, pay foreign-trade taxes, and comply with non-tariff regulations and customs formalities. [3]
ARI Electronics is responsible for providing accurate and consistent export information according to the order. The Mexican importer and its customs broker are responsible for the local import declaration, tax payment, and customs process.
Step 8: Receive, store, and manage after-sales service
After release, the Mexican buyer should retain the pedimento, tax-payment records, broker invoice, supplier documents, and warehouse records. If the model, construction, packaging, or included accessories change in a later shipment, the buyer should review the classification and NOM position again.
6. How Mexican Import VAT Is Calculated
Mexico’s Value Added Tax Law provides that imports of goods are subject to VAT, generally called IVA in Mexico, at a standard rate of 16%. Article 24 treats the entry of goods into Mexico as an import, and Article 26 generally treats the import as occurring when the importer presents the pedimento for processing. [4]
Article 27 provides that the VAT base for imported tangible goods is the value used to calculate the general import tax, plus the IGI and other taxes, duties, or charges payable as a result of the importation. [4]
For preliminary budgeting, a Mexican buyer can use the following simplified formulas:
Customs value = Transaction value + includable freight, insurance, and additions
IGI = Customs value × Applicable IGI rate
VAT base = Customs value + IGI + other import taxes, duties, and charges
Import VAT = VAT base × 16%
Import VAT should not be estimated simply by multiplying the ARI Electronics invoice amount by 16%. The customs value, applicable IGI, and other import charges may affect the final VAT base. The formal calculation should be based on the customs broker’s estimate and the applicable Mexican rules.
7. How to Calculate the Landed Cost of Mobile Screens from ARI Electronics
Mexican buyers should distinguish between the supplier purchase price and the full commercial cost of receiving the goods at a Mexican warehouse. The following items should normally be considered in the budget:
| Cost item | Budget consideration |
| ARI Electronics product price | Important purchase-cost and customs-value element |
| International freight and insurance | Depends on Incoterm, weight, volume, and transport method |
| IGI | Calculated using the final TIGIE/NICO and current rate |
| Import VAT/IVA | Calculated under the Article 27 VAT-base logic |
| DTA or other import charges | Confirm with the Mexican customs broker under current rules |
| Customs-broker service fee | Include in commercial landed cost and check whether VAT is added |
| Port, terminal, storage, and inspection charges | Affected by port, transport method, inspections, and delays |
| NOM testing, certification, labeling, and translation | Include in the procurement budget if applicable |
| Mexican inland transportation | Cost from the port or airport to the customer’s warehouse or distribution center |
| Inspection, warranty, and inventory-loss costs | Include in the wholesaler’s final pricing model |
Whether import VAT is creditable depends on the Mexican importer’s tax position and applicable local rules. For cash-flow planning, however, the buyer should include the import VAT that may be payable at customs.
8. Landed-Cost Example for a Mexican Wholesale Order
The following is an illustrative example only. It does not represent ARI Electronics’ actual quotation, Mexico’s actual tariff rate for a particular screen, or a specific customer’s brokerage charges.
Assumptions:
•ARI Electronics product price: USD 12,000;
•International freight and insurance assumed includable in customs value: USD 960;
•Assumed customs value: USD 12,960;
•Assumed IGI rate: 10%;
•Assumed other import charge: 0.8% of customs value;
•Mexican customs-broker service fee: USD 600;
•Port and local handling charges: USD 400;
•Mexican inland delivery: USD 300;
•Exchange-rate effects, banking fees, actual NOM expenses, and after-sales costs are excluded.
| Calculation item | Formula | Illustrative amount (USD) |
| Customs value | 12,000 + 960 | 12,960.00 |
| IGI | 12,960 × 10% | 1,296.00 |
| Illustrative import charge | 12,960 × 0.8% | 103.68 |
| VAT base | 12,960 + 1,296 + 103.68 | 14,359.68 |
| Import VAT | 14,359.68 × 16% | 2,297.55 |
| Illustrative commercial landed cost | 12,000 + 960 + 1,296 + 103.68 + 2,297.55 + 600 + 400 + 300 | 17,957.23 |
Under these assumptions, the product purchase price from ARI Electronics is USD 12,000, while the illustrative commercial landed cost for the Mexican buyer is USD 17,957.23. This is approximately 1.50 times the purchase price. The ratio applies only to these assumptions and should not replace a formal quotation.
The example demonstrates two important points. First, import VAT is not calculated simply from the supplier invoice amount. Second, customs-broker fees, port charges, and inland transportation should be listed separately and should not all be added to the VAT base without a legal or accounting basis. The Mexican buyer should analyze the products quotation, freight-forwarder quotation, and customs-broker tax estimate together.
9. How ARI Electronics and Mexican Buyers Can Reduce Import Risk
9.1 Use consistent model and commercial descriptions
ARI Electronics’ quotation, commercial invoice, and packing list should use clear English descriptions and identify the brand, model, screen type, quality grade, and quantity. The Mexican buyer’s purchase order should use the same information.
9.2 Provide technical documents that support classification
ARI Electronics can provide specifications, photographs, dimensions, weight, interfaces, and packing information so that the Mexican buyer can explain the product accurately to its customs broker.
9.3 Do not promise an unverified tariff rate
ARI Electronics may provide an export-side HS reference, but the Mexican buyer must confirm the complete TIGIE/NICO, IGI, and NOM position with a local broker. An unverified tariff rate should not be presented as a final landed-cost commitment.
9.4 Keep samples, volume goods, and documents consistent
If the display technology, touch layer, driver board, packaging, or included accessories change, the supplier and importer should review the product documentation, classification, and regulatory requirements again.
9.5 Show the customer the full cost before ordering
The Mexican buyer should understand the product price, freight, IGI, import VAT, brokerage, port charges, storage, inland transportation, compliance costs, and after-sales costs. ARI Electronics’ quotation should clearly state which costs are included and which costs remain the responsibility of the Mexican buyer.

Make ARI Electronics Your China-to-Mexico Supply Partner
Importing mobile phone screens from China to Mexico should be managed as a complete supply-chain process rather than as a simple price purchase. ARI Electronics can support Mexican customers from the China side by providing product specifications, packaging information, commercial documents, and order coordination. The Mexican customer, together with its local customs broker, is responsible for confirming the TIGIE/NICO classification, NOM requirements, taxes, and import declaration.
The HS code should not be based only on a supplier’s six-digit reference. NOM applicability should not be determined solely by the product name. Import VAT should not be calculated only from the invoice value. Landed cost should not be measured only by the screen unit price.
The most reliable process is:
Confirm the product configuration → prepare technical documents → confirm Mexico’s TIGIE/NICO classification → check NOM → select the Incoterm and transport method → calculate IGI and import VAT → clear customs and deliver to the Mexican warehouse.
If you are a Mexican mobile-parts wholesaler, repair-chain purchasing manager, distributor, or electronics importer, send ARI Electronics the target models, estimated quantities, quality grade, delivery city, and preferred Incoterm when requesting a quotation. The more complete the information, the more effectively ARI Electronics can prepare a clear wholesale quotation, product-document package, and delivery plan for importing from China to Mexico.
