1. What U.S. import data measures

USITC DataWeb provides public access to official U.S. import and export statistics published by the U.S. Department of Commerce, Census Bureau. Users can query trade flow, classification, measures, periods, partners, and commodities. USITC - DataWeb That makes DataWeb a strong source for questions such as:

• Is product flow persistent, growing, declining, volatile, or seasonal?

• Which partner countries account for recorded imports in the classification?

• Are value and reported quantity moving in the same direction?

• Does a change remain when the product group is narrowed?

• Did an HTS change alter the time series? It cannot directly answer:

• Which named companies bought the goods?

• Which final applications used them?

• How much inventory remains unsold?

• What buyers paid after freight, duty, distribution, installation, and service?

• Whether buyers are satisfied or willing to switch suppliers?

• What share of total U.S. demand is served by domestic production? Official fact: USITC states that public DataWeb statistics aggregate individual company activity so confidential firm-level information is not disclosed. USITC - Company-level data limitations

2. Choose general imports or imports for consumption

The two flows answer different timing and customs-status questions. General imports Official fact: General imports measure physical arrivals from foreign countries, including goods entering consumption channels immediately and goods entering bonded warehouses or Foreign Trade Zones under customs custody. U.S. Census Bureau - International Trade Definitions Imports for consumption Official fact: Imports for consumption measure merchandise that has cleared through Customs into consumption channels, either immediately or after withdrawal from bonded warehouses or Foreign Trade Zones. U.S. Census Bureau - International Trade Definitions SellersGPT recommendation: For many commercial-demand screens, imports for consumption are the clearer starting flow because they measure clearance into U.S. consumption channels. Use general imports when physical arrival, warehousing, or zone movement matters. State the chosen flow and do not combine them. Neither flow means the product has been consumed by an end user or sold through retail or distribution.

3. Build a reproducible query

Use the SellersGPT U.S. Import Query Card.

1. Decision question Write the question before opening the database. Example: Is U.S. import activity in the narrow product classification persistent enough to justify account-level validation in selected industrial regions?

2. Product classification Record:

• current HTS code and description;

• code level used;

• included and excluded products;

• current schedule version;

• predecessor or successor codes for the selected period;

• reason the classification fits the product. Use USITC HTS Search and qualified classification review where material. A six-digit query can improve international comparability but may combine multiple U.S. ten-digit products. A ten-digit query can be precise but may have code changes or suppressed quantities.

3. Trade flow Select General Imports or Imports for Consumption and document why.

4. Measures and valuation Request customs value and relevant first or second quantities when available. Do not assume the quantity unit is pieces. Official fact: U.S. customs value is generally the price paid or payable for merchandise sold for export to the United States, excluding U.S. import duties and freight, insurance, and related charges incurred in bringing the merchandise to the United States. U.S. Census Bureau - Information on Trade Statistics Customs value is therefore not landed cost, distributor revenue, end-user spend, or market revenue.

5. Partner basis Select all partners for the market total, then review relevant country detail. Preserve the exact partner concept shown in the query and avoid mixing country groupings across runs.

6. Period and frequency Use enough history to see volatility and seasonality, often monthly and annual views across several years. Record partial-year cutoffs and compare like periods.

7. Data status Record retrieval date, update date, revisions, suppressed quantity markers, and system warnings. USITC says Census revises historical merchandise trade data, including annual revisions affecting prior years. USITC - DataWeb FAQs

8. Export the query definition Save the query parameters and raw export before transforming data. Name every calculation column.

4. Interpret value, quantity, price, and mix

Read value and quantity together If value rises and quantity rises, commercial flow may be expanding. If value rises while quantity is flat, the change may reflect price, specification, mix, valuation, or quantity-quality issues. If quantity rises while value falls, unit composition or pricing may have changed. Unit value is not transaction price When quantity is usable, calculate: customs value / reported quantity = average customs unit value Label it calculated from official data with the code, flow, partner, period, currency, and quantity unit. It is an aggregate ratio. It can change because product mix, related-party valuation, quality, package size, or classification changes - not only price. Check concentration Partner-country concentration can show supply exposure or a dominant source pattern. It cannot identify buyer concentration. A customs-district concentration can show where goods enter, not necessarily where they are used. Check the classification timeline USITC DataWeb introduced warnings and suggestions related to classification changes and suppressed quantity data. A code split can make one line appear to collapse even when the product flow moved to successor lines. USITC - DataWeb 5.0 capabilities Reconcile other explanations Before calling a pattern demand, test:

• domestic production and exports;

• inventory and warehouse timing;

• one-time projects or shipments;

• tariff or trade-policy changes;

• related-party transfers;

• exchange rates and commodity costs;

• classification or reporting changes;

• product mix within the code;

• seasonality and incomplete periods.

5. Use the SellersGPT Import Evidence Ladder

Import data becomes more decision-useful as it is connected to additional evidence. Level Evidence Responsible conclusion

1. Classification Verified product scope and code history The query covers these goods with stated limitations.

2. Flow Value, quantity, partner, period, and revisions Recorded import activity has this pattern.

3. Market structure Domestic activity, establishment clusters, route, and regulation The flow exists within this broader supply and buyer environment.

4. Account and application Named facilities and evidence of relevant These accounts may fit the application. use

5. Primary validation Buyer, channel, service, and technical evidence The hypothesis is ready for Go, Test, or Wait review. Do not publish a Level 5 conclusion from Level 2 data. Reproducibility line for every chart Include: Source | DataWeb query | HTS code and vintage | flow | measure | partner | period | currency | quantity unit | retrieval date | calculation USITC provides a recommended citation format for merchandise trade data and distinguishes DataWeb statistics from the official HTS used for tariff information.

6. Illustrative example

Illustrative example. The values and product are fictional. No market forecast or customer result is implied. A team queries imports for consumption for a narrowly reviewed machinery classification. Annual customs value increases from an illustrative USD 10 million to USD 12 million, while reported quantity is exactly 1,000 reported units in each period. Calculated from fictional data: Average customs unit value changes from USD 10,000,000 / 1,000 = USD 10,000 to USD 12,000,000 / 1,000 = USD 12,000 per reported unit. The responsible conclusion is not "demand grew 20 percent." The recorded customs value grew 20 percent while reported quantity was unchanged at 1,000 reported units. Possible explanations include price, product mix, specification, valuation, or quantity issues. The next steps are to check code continuity, monthly and partner patterns, quantity warnings, product mix, domestic supply, and relevant accounts. Buyer interviews then test whether replacement, expansion, compliance, or lead-time conditions are actually changing.

7. Common mistakes

Calling import value market size Imports omit domestic production and do not equal downstream revenue or end-user spending. Treating one year as a trend Use comparable multi-year and monthly views, note partial periods, and inspect unusual shipments. Ignoring quantity units Weight, count, area, volume, and other units cannot be interchanged. Some quantities may be missing or suppressed. Dividing value by quantity and calling it price Use "average customs unit value" and disclose aggregation limits. Using a broad code because it creates a larger number Choose the narrowest defensible scope and disclose mixed products. Inferring named importers Public official trade data does not disclose individual firm activity. Treat commercial shipment databases as separate sources with their own methods and limitations. Reading ports as customer locations Entry location is not necessarily final destination or application location. Ignoring revisions and code changes Preserve retrieval date and rerun material charts at decision points.

8. What this guide does not mean

• It does not classify a product or determine tariff, origin, admissibility, duty, or customs compliance.

• It does not estimate total U.S. demand without domestic-production and other relevant evidence.

• It does not identify importers, buyers, facilities, applications, or purchase intent.

• It does not predict leads, meetings, orders, market share, or revenue.

• It does not treat official data as error-free, final, or perfectly current.

• It does not replace qualified customs, legal, regulatory, or statistical advice.

9. Common questions

Should I use monthly or annual data? Use both when the decision requires trend and timing. Monthly data reveals volatility and seasonality; annual data reduces noise. Compare complete like periods. Which is better: six-digit HS or ten-digit HTS? Use the narrowest level that validly represents the product and provides a continuous, interpretable series. Six digits improve international comparability but can be broad; ten digits improve U.S. detail but can change and may have quantity limitations. Can I use import growth to choose a market? Use it as one demand signal. Combine it with account density, application fit, buyer access, competitive conditions, entry requirements, domestic supply, and economics. How do I know whether a jump is real? Check code history, monthly distribution, partner and quantity patterns, revisions, warnings, product scope, and alternative explanations. Then corroborate with market and account evidence.
